Fenaflex

Couplings

Fenaflex couplings provide all the desirable features of an ideal flexible coupling, including Taper-Lock® fixing.The Fenaflex coupling is a "torsionally elastic" coupling offering versatility to designers and engineers with achoice of flange combinations to suit most applications.The flanges are available in either F or H Taper-Lock® fitting or pilot bored, which can be bored to the required size.With the addition of a spacer the coupling can be used to accommodate standard distances between shaftends and thereby facilitate pump maintenance.Fenaflex couplings can accommodate simultaneous maximum misalignment in all planes without imposingundue loads on adjacent bearings and the excellent shock-absorbing properties of the flexible tyre reducevibration and torsional oscillations.Fenaflex tyres are available in natural rubber compounds for use in ambient temperatures between –50OCand +50OC. Chloroprene rubber compounds are available for use in adverse operating conditions (e.g. oil orgrease contamination) and can be used in temperatures of –15OC to +70OC. The chloroprene compoundshould also be used when fire-resistance and anti-static (F.R.A.S.) properties are required.

SELECTION

(a) Service Factor

Determine the required Service Factorfrom table below.

(b) Design Power

Multiply the normal running power bythe service factor. This gives the designpower which is used as a basis forselecting the coupling.

(c) Coupling Size

Refer to Power Ratings table(page 195) and from the appropriatespeed read across until a power greaterthan that required in step (b) is found.The size of Fenaflex coupling requiredis given at the head of that column.

(d) Bore Size

Check from Dimensions table(page 196) that chosen flanges canaccommodate required bores.

EXAMPLE

A Fenaflex coupling is required to transmit45kW from an A.C. electric motor whichruns at 1440 rev/min to a rotary screen for12 hours per day. The motor shaft is 60mmdiameter and the screen shaft is 55mmdiameter. Taper Lock is required.(a) Service Factor

The appropriate service factor is 1,4.(b) Design Power

Design power = 45 x 1,4 = 63kW.(c) Coupling Size

By reading across from 1440 rev/min inthe power ratings table the first powerfigure to exceed the required 63kW instep (b) is 75,4kW. The size of couplingis F90 Fenaflex.

(d) Bore Size

By referring to the dimensions table itcan be seen that both shaft diametersfall within the bore range available.

Dimensions in millimetres unless otherwise stated.

§ G is the amount by which clamping screws need to be withdrawn to release tyre.† J is the wrench clearance to allow for tightening/loosening the bush on the shaft and the clamp ring screws on sizes F40, F50 and F60. The use of a shortened

wrench will allow this dimension to be reduced.¶ M is half the distance between flanges. Shaft ends, although normally located twice M apart, can project beyond the flanges as shown. In this event

allow sufficient space between shaft ends for end float and misalignment.* Mass and inertia figures are for single flange with mid range bore and include clamping ring, screws and washers and half tyre.‡ For pilot bore 'B' flange code as listed.

Flanges are also available finish bored with keyway if required.Bore must be specified on order.

# Note: On sizes F70, 80, 100 and 120 the 'F' direction bush is larger than that in the 'H'direction.

Fenaflex Spacer Couplings

Comprising a Fenaflex tyre coupling (sizeF40–F140) complete with a spacer flangedesigned for use on applications where it isan advantage to be able to move eithershaft axially without disturbing the driving ordriven machine (e,g, centrifugal pumprotors), Fenaflex spacer couplings areprimarily designed for standard distancebetween shaft end dimensions 100, 140 and180mm.

SELECTION1. Select a suitable size of Fenaflex

coupling using the method shown onpage 194. Read down the first columnin table below and locate the size ofcoupling selected.

2. Read across until the required distancebetween shaft ends can beaccommodated.

3. Note the required spacer coupling

designation at head of column.

4. Check from the Spacer CouplingDimensions table below that theselected spacer/coupling combinationcan accommodate the machine shaftsize.

INSTALLATION INSTRUCTIONS

Note: Satisfactory performance depends oncorrect installation and maintenance. Allinstructions must therefore be followedcarefully.

1. Thoroughly clean all components, payingparticular attention to the removal of theprotective coating in the bore of the drivenflange.

2. Slip bolt ring, clamping, and then element(with large diameter facing flywheel) ontodriven shaft. Fit flange to shaft. (Where aTaper Lock® bush). Locate flange on shaftso that dimension M will be achieved onassembly (see paragraph 3).

3. Bring driven shaft into line with flywheeluntil dimension M is correct (see table). Ifshaft end float is to occur, locate driven shaftat mid position of end float when checkingdimension M. Note that driven shaft mayproject beyond the face of the flange ifrequired. In this event, allow sufficientspace between shaft end and flywheel forend float and misalignment.

4. Accurately align driven shaft with flywheel.Check both parallel and angular alignmentby mounting a dial indicator near the outsidediameter of the flange (as shown) androtating the flywheel through 360o. Indicatorreadings for both parallel and angularalignment should not exceed the valuesgiven in the table overleaf. Then bolt drivenmachine in place.

5. Place flexible element and bolt ring* inposition, fit screws finger tight. Placeclamping ring in position and fit screwsfinger tight.

6. Working alternately and evenly round eachflange, tighten each screw (approx. 1/2 turn)until the required screw torques areachieved – see table.

R

† For 213W Flywheel coupling M - 104 mm when adaptor ring fitted, see diagram.Note: It may be necessary to back off the shaft to allow room to remove and replace theflexible element.

WHR and WBR Configurations

These flanges are available for use inapplications where close-couplings is essential.It should be noted that the coupling must beassembled on the driven machine shaft beforeoffering the driven machine up to the engine,i.e. First place bolt ring on driven shaft then fitdriven flange, element and clamping ring. Takecare to position the driven flange so that thecorrect dimension Lr will be achieved onassembly (see table). Tighten the clamping ringscrews alternately and evenly (1/2 turn each) untilthe required screw torques are achieved. Afterthe two machines are brought together the boltring screws should be inserted and tightenedalternately are achieved.

• On size 213W only, place bolt ring adaptorbetween flexible element and flywheel. Line upunthreaded holes in adaptor with threaded holesin flywheel and fit the 6 long screws into theseholes. Fix the 6 short screws in the other holes.

These semi-elastic couplings designed for general purpose use, permit quick and easy assembly by means of Taper-Lock® bush fixing.Fully machined outside diameters allow alignment by simple straight edge methods.Shaft connection is "fail safe" due to interacting dog design.

SELECTION(a) Service Factor

Determine appropriate Service Factorfrom table below

(b) Design PowerMultiply running power of drivenmachinery by the service factor. Thisgives the design power which is usedas a basis for coupling selection.

(c) Coupling SizeRefer to Power Ratings table belowand read across from the appropriatespeed until a power equal to or greaterthan the design power is found. Thesize of coupling is given at the head ofthat column.

(d) Bore SizeFrom Dimensions table on page 204check that the required bores can beaccommodated.

EXAMPLEA shaft coupling is required to transmit70kW between a 1200 rev/min dieselengine and a hoist running over 16hrs/day.Engine shaft is 70mm and the hoist shaft is75mm.(a) Service Factor

The appropriate service factor is 2,5.(b) Design Power

Design power 70 x 2,5=175kW.

(c) Coupling SizeReading across from 1200 rev/min inthe speed column of Power Ratingstable below, 251kW is the first powerto exceed the required 175kW (designpower). The size of the coupling at thehead of this column is 230.

Satisfactory performance depends on

correct installation and maintenance. All

instructions in this manual must therefore

be followed carefully.

1. Thoroughly clean all components, payingparticular attention to the removal of theprotective coating in the bore of the drivenflange.

2. Fit driven flange (with driving dogs facingflywheel) onto driven shaft. (Where a TaperLock® Flange is used, see separate fittinginstructions supplied with the Taper Lock®

Bush). Locate flange on shaft so thatdimension ‘M’ will be achieved on assembly(see paragraph 3).

3. Bring driven shaft into line with flywheeluntil dimension ‘M’ is correct (see tablesoverleaf). If shaft end float is to occur, locatedriven shaft at mid position of end floatwhen checking dimension ‘M’. Note thatdriven shaft may project beyond the faceof the flange if required. In this event, shaftdiameter + key must be within the borediameter ‘E’ of the element (see tableoverleaf). Allow sufficient space betweenshaft end and flywheel for end float andmisalignment.

4. Fit driving flange to flywheel, using screwsfrom appropriate screw pack (to suit threadtype in flywheel). Initially screws should befinger tight. Check location surface i.e.outside diameter or spigot in back face offlange are seating square with flywheel.Alternatively flange location can be achievedby using dowel pins. (2 at 180o).

5. Working alternately and evenly round theflange, tighten each screw until the requiredscrew torques are achieved – as below.

6. With open assembly type drives check bothparallel and angular alignment by placingstraight edge across the coupling usingsetting diameter on flywheel flange andshroud on driven flange (as shown below).Re-check with straight edge after rotatingthe flywheel through 180o.

NOTES ON THE INSTALLATION OFUNIVERSAL JOINTS

LUBRICATIONFor both intermittent and continuouslyrated joints where constant lubrication(such as an oil bath) is not available, jointcovers suitable for grease packing arerecommended. These are available for allsizes of single joint and can be used in pairson double joints.

Where the use of covers is not practical,the working areas of the joint must be oiledat least once a day.

Where constant angular velocity throughout each revolution of the connected shafts isrequired, the working angles must be equal - see Fig. 1. Where an intermediate shaft isused either telescopic (to accommodate lateral movement between the driving anddriven shafts) or plain, the relationship of the joint ends must be as shown in Fig. 2.

Applications involving tension or compression of the universal joint should be referredto Fenner Power Transmission Distributor.

FIG. 2

2. The torque to be transmitted is 105,05N.m but since the joint angle is 20o onemust select a joint of larger dimensionsand torque carrying capacity tocompensate.

Since the torque factor for 20o is 0,75(as indicated on the table 2) one dividesthe torque factor M by factor F.

Taper-Lock® Rigid Couplings — Cast Iron

Taper-Lock® Rigid Couplings provide a convenient method of rigidly connecting ends of shafts. Taper-Lock® Bushes permit easier andquicker fixing to the shafts with the firmness of a shrunk-on fit. These couplings have a male and female flange fully machined. The maleflange can have the bush fitted from the Hub side H or from the flange side F; the female flange always has bush fitting F. This gives twopossible coupling assemblies HF and FF. When connecting horizontal shafts, the most convenient assembly should be chosen. When

connecting vertical shafts use assembly FF only.

This Coupling has many outstanding advantages and is supplied in three alternative assemblies: HH, FF and HF as shown on page 168.These enable the Taper-Lock® Bush to be fitted from the hub side or the flange side, the choice depending on the application.

The flanges and Taper-Lock® Bushes are of close-grained cast iron, machined to close tolerances and the flexible disc is of a non- metallicrubber-impregnated fabric. The unit is designed and manufactured to the high standard already long associated with other Fenner products.

LONG LIFEThe power ratings are based on a life concept. They assume that misalignment is present and are such that long life of pins and disc, bothof which are replaceable, will be realised at all permitted speeds. Under conditions of perfect alignment the nominal torque capacity of thecoupling at 100 r/min is, of course, available at higher speeds.

THE ELIMINATION OF TIGHT PRESS FITTINGThe separate operation of press-on or shrunk-on fitting is done automatically when, on tightening the grub-screws, the Bush is drawn intothe flange.

THE ELIMINATION OF RE-BORINGWith Taper-Lock® Bushes, reboring is not necessary. Bushes to suit all normal shaft sizes from 10 mm to 90 mm are obtainable ‘off theshelf’.

EASY REMOVAL OR REPLACEMENTTo replace the central disc or to repair one of the coupled units, coupling dismantling and re-assembly is greatly simplified; there are no boltsto disconnect, and the flange is removed simply by slackening the Taper-Lock® Bush. The hole in the disc will permit the shafts to projectbeyond the faces of the flange where this is necessary, and will permit the flanges and the disc to be slid along one of the connected shaftswhere required.

FLEXIBILITYThe Coupling accommodates accidental parallel or angular shaft misalignment; it provides resilience against shock loads; it reduces oreliminates the transmission of torsional vibration.

SELECTION – FROM DRIVEN MACHINE REQUIREMENTDetails required for coupling selection are:

(1) Type of driven machine and operating hours per day.(2) Speed and power absorbed by driven machine (if absorbed power is not known calculate on power rating of primer mover).(3) Diameter and length of shafts to be connected.

NORMAL SERVICE / 1

Bakery dough mixers - compressors(centrifugal; 3 or more cylinders) -conveyors (apron, belt, chain, screw) -elevators (bucket) - fans and blowers(centrifugal, propeller) - generators andexciters - laundry machinery - line shafts -machine tools - printing machinery - pumps(centrifugal: rotary: 3 or more cylinders) -screens (conical, revolving) - textile reels -warpers - wood working machinery.

PROCEDURE(a) Service Factor

Determine appropriate Service Factorfrom table 1.

(b) Design PowerMultiply running power of drivenmachine by the service factor. Thisgives the design power which is usedas a basis for coupling selection.

(c) Coupling SizeRefer to table 2 and read across fromthe appropriate speed until a powerequal to or greater than the designpower is found. The size of coupling isgiven at the head of that column.

(d) Bore SizeFrom dimension table 3 check that therequired bores can be accommodated.

EXAMPLEA shaft coupling is required to transmit70kW between a 1200 r/min d.c. electricmotor and a mixer running 8hrs/day. Motorshaft is 70mm and the mixer shaft is75mm.(a) Service Factor

From table 1 the service factor is 1.(b) Design Power

Design power 70 x 1 = 70kW.

(c) Coupling SizeReading across from 1200 r/min in thespeed column of table 2 93,3kW is thefirst power to exceed the required70kW (design power). The size of thecoupling at the head of this column is254.

(d) Bore SizeTable 3 shows that both shaftdiameters are within the bore rangeavailable.

Selection MethodSelection Processes

1) By using the following formula, obtain DesignTorque required.

Torque (Nm) = Power (kW) x 9550 x S.FSpeed (Rev/min)

2) Select the size with the same or with greater valuein the Basic Torque column. Refer to the maximum speed allowedto the size selected and then compare the shaft diameters of theapplication with the maximum bore diameter of the size selcted. Ifthe coupling bore size is not suitable, select the larger couplingsize.

3) Special requirements:A. On calculating the torque required use the

lowest operating speed of the application.B. If there are reverse motions repeatedly or

frequent irregular load changes, double the service factor.

Example

When you select a COUPLING to connect a 45 kW 1440rpm motor to a rotary type pump, with shaft diameters of 60mmfor the motor and 52mm for the pump. Service factor from tableis 1,75 (from Page 218)

T = 45 x 9550 x 1.751440

T = 522.26 Nm

The coupling size 1060 accepts the calculated torque of522.26 Nm and then compare the application shaft size (60mm)to the maximum bore of the selected coupling size 1060(55mm). You will select the coupling size 1070 accepting up to65mm shaft diameter. The size also accepts the applicationmotor speed 1440 rpm. Either TH or TV covers are available.Finally the coupling size 1070 is selected.

4) TORSIONAL FLEXIBILITYTorsional flexibility is the advantage of Taper Grid Couplings.Providing flexible accommodation to changing load conditions.

Characteristics and Merits

Vibration Absorption Shock Load Absorption

Taper Grid Couplings demonstrate the excellent performance as shown below

3) AXIALEnd Float for both driving and driven members is permittedbecause the grid slides freely in the lubricated grooves.

SHOCK LOADThe coupling is flexible within its rated power capacity. Underextreme overloads, the grid bears fully on the hub teeth andtransmits full load directly.

2) ANGULARUnder angular misalignment, the grid-groove design permits arocking and sliding action of the lubricated grid and hubswithout any loss of power through the resilient grid.

NORMAL LOADAs the load increases, the distance between the contact pointson the hub teeth is shortened, but a free span still remains tocushion shock loads.

1) PARALLELThe movement of the grid in the lubricated groovesaccommodates parallel misalignment and steel permits fullfuntioning of the grid - groove action in damping out shock andvibration.

LIGHT LOADThe grid bears near the outer edges of the hub teeth. The longspan between the points of contact remains free to flex underload.

Escogear

ADVANTAGE

WHY ESCOGEAR?

High torque and misalignment capacityThanks to the patented Escogear Multicrown profile (used on the C and F series), theoptimised coupling design and the standard use of 12,9 quality bolts, the Escogear couplingsoffer the user a very high torque capacity.

This means that for a given torque a smaller coupling can be used which results in moreefficient machine design and performance. Furthermore, this high torque is available atimportant angular misalignment.

Transparent coupling selectionThe torque capacity of a gear type coupling strongly depends on the angular misalignmentto which it is subjected: the higher the misalignment, the lower the torque capacity. It isclear that this relationship can and will cause problems in coupling selection becausemisalignment during operation is almost impossible to predict. Escogear couplings of the Fand C...M type are equipped with Esco Multicrown tooth form. Thanks to this quite uniquedesign, the Escogear has a torque capacity that is practically independent of the angularmisalignment. Therefore, coupling selection is easy and mistakes are avoided: long couplinglife is guaranteed.

High precision gearingPitch error in the gearing of coupling can strongly affect, the load distribution between theteeth can be strongly influenced. In come cases, the maximum load applied on the teethcan be twice the value of the load calculated. The consequence will be higher surface androot stresses and coupling failure might be the result. Thanks to the high precisionmanufactured, and the sophisticated quality control, pitch error is minimized and the bestpossible gear quality level and life time can be guaranteed.

Reduced backlashOne of the consequences of the Multicrown design is that the necessary backlash betweenthe teeth can be reduced to an absolute minimum. This will reduce the impact loads in start/stop and reversing torque applications. As a result, the teeth can be designed with a largersection and the root stresses will be reduced. Thanks to this feature the Escogear couplingsare ideal for use in presses, mills, punching machines, portal cranes etc.

Perfect gear top centringGear type couplings require, in order to operate, a “clearance” between the top of each hubtooth and the root of the sleeve teeth. Due to this clearance, the sleeve cannot be perfectlycentred on the hubs. This will create vibrations in applications where the load constantlychanges from no load to full load (e.g. portal cranes). These vibrations will of course influencethe operation of the connected equipment. Thanks to special design and machiningtechniques, Esco is able to pilot the top of each hub tooth into the root of the sleeve teeth.By doing so, the sleeve will remain perfectly centred on the hub and vibrations will beavoided. This specific feature is standard on all F and C...M couplings.

Excellent protection of componentsIn order to guarantee optimum operation, all Escogear couplings are protected with specialsurface treatment or coating. All bolts are coated with Dacromet and the nuts are zincplated which gives an excellent corrosion resistance and makes disassembly possible, evenafter numerous years of service life. Furthermore, all the steel components are protectedwith a special coating to improve their corrosion resistance.

Lower stressesThe Esco Multicrown tooth form is a curvewith constantly changing radii of curvature.The tooth contact area under misalignedconditions has a much larger radius ofcurvature than conventional crowning. Thecontact area therefore is larger thus reducingthe surface stresses.

Constant velocity power

Less backlashThe Esco Multicrown tooth design requiresless backlash for a given angle ofmisalignment than the conventionalcrowning, thus reducing shocks in reversingapplication.

TABULATION 2

HOW TO USE THE GRAPH?

Maximum torque, maximum speed and maximum misalignment may not occur simultaneously.Graph must be used as follow:

1. Calculate Tn and Tp and select coupling size as usual. Tn = nominal torque – Tp = peak torque.2. Calculate Tn/Tnref and N/Nref and plot the resulting point in the graph.3. If the resulting point is located in the white area, a standard coupling may be used as far as maximum misalignment doesn’t exceed the

maximum misalignment indicated in the graph.4. If the resulting point is located in the shaded area, refer to Fenner Power Transmission Distributor.

SERIES N - C - F

HOW TO SELECT THE RIGHT COUPLING SIZE

A. Select the size of Escogear coupling that will accommodate the largest shaft diameter.B. Make sure this coupling has the required torque capacity according to following formula:

torque in Nm = 9550 x P x Fu

n

P = power in kW — n = speed in rpm — Fu = service factor according to tabulation 1.The coupling selected (A) must have an equal or greater torque capacity than the result of the formula (B). Otherwise select a larger sizecoupling.Check if peak torque does not exceed tabulated peak torque Tp indicated in the selection chart.Check also max. allowable misalignment using the graph of tabulation 2.C. Check if shaft/hub connection will transmit the torque. If necessary, select a longer hub.

ESCO FST SERIES

1. Introduction

Coupling must be selected properly according to selection chart . These documents are available from page 183 or on our web site"www.escocoupling.com". Maximum misalignment figures at assembly are given is this document (see point 4: assembly). Max misalignment,max speed and max torque may not be applied simultaneously. In case of any change or adaptation not performed by ESCO on the coupling, itis customer responsibility to size and manufacture it properly to guarantee safe torque transmission and absence of unbalance that could affect thelife of the coupling and the connected machines. It is customer responsibility to make sure that shaft and key material, size and tolerance suit theapplication. Maximum bore capacity is given in the catalogue. It is customer's responsibility to make sure that hub length, bore size and machiningtolerances will transmit the torque. It is customer's responsibility to make sure that interference and machining tolerances will transmit the torqueand not exceed hub material permissible stress. The hubs must be axially secured on the shaft by means of a setscrew, an end plate or a sufficientinterference. It is customer's responsibility to size and manufacture it properly to guarantee safe torque transmission and absence of unbalancethat could affect the life of the gearing. It is customer responsibility to protect the coupling by p.ex. a coupling guard and to comply with the localsafety rules regarding the protection of rotating parts.

2. Preparation

Ensure the conformity of the supplied equipment:– Verify coupling size and conformity (see catalogue or web site)– Identify any damaged and/or missing parts– Verify conformity of the coupling/machine interfaces.Coupling original protection allows for storage indoors dry 18 months, indoor humid 12 months, outdoors covered 9 months and outdoors open 3months. For longer periods, it is customer responsibility to protect the parts properly. Instructions are a part of the supply of the coupling. Be surevalid and complete assembly, operation and maintenance instructions are available. Make sure they are well understood. Assembly, disassemblyand maintenance must be performed by qualified, trained and competent fitters. Before starting with assembly, disassembly and maintenance,verify the availability of the tooling necessary.– To manipulate the parts – To assemble the interfaces – To align the coupling – To tighten the screws and nuts

3. Warnings

Before removing the coupling guard and proceeding with any assembly, operation or maintenance operation of the coupling, make sure thecomplete system is completely shut down and definitively disengaged from any possible source of rotation, such as, for example:– Electrical power supply – Any loss of braking effect.Make sure everyone attending the equipment area will be properly informed (for example by means of warning properly located) about themaintenance or assembly situation.In case of use in explosive atmospheres , specific protective measures must be considered. They are described in an extra attachment(IM/A200-Ex) to the actual instructions with the couplings marked .

4. Assembly

4.1. Coupling without end-cap

4.1.1. Ensure all parts are clean.4.1.2. Apply a light coat of grease to the O-Rings A and insert O-Rings into grooves J of sleeves B.4.1.3. Place sleeves B over shaft ends. Care should be taken not to damage O-Rings A.4.1.4. Install hubs C on their respective shafts with the longest hub end towards shaft end or towards machine bearing depending on the

type (see fig. 1 and 3). If needed, for keyway assembly, uniformly heat hubs C (max 120˚C) to install them easily on the shaft, in thiscase, avoid any contact between the hub C and O-Ring A. Hub faces have to be flush with shaft end. In case of doubt, please consultus. Introduce setscrew on key with Loctite and tighten properly.

4.1.5. Install units to be connected in place and check the spacing G between hubs. See tabulation or approved drawing for correct hubspacing G, according to coupling size. In case of doubt, please consult us.

4.1.6. Align the two shafts, check alighment using an indicator. Alignment precision depends on running speed (see tabulation 4).4.1.7. Coat hub and sleeve gearing with grease (see tabultaion 3) and slide sleeves B over hubs.4.1.8. Insert gasket F and bolt sleeves together. Tighten bolts uniformly. See tabulation 2 for correct tightening torque (T1 Nm). Make sure

that sleeves are freely sliding over hubs by axially displacing it to a value equal to G (see tabulation 1).4.1.9. For the types FST, FMM and FDMM, remove both lube plugs H of one sleeve B and add grease in sufficient amount to overflow with

lubricant holes in horizontal position. For types FFS, FSE, FSLE, FLE, FSP, FIN and FSV repeat this operation for the second sleeve. Forquantity and quality of grease, see tabulation 3. Re-install the 2 plugs H; see tabulation 2 for correct tightening torque (T3 Nm) and keysize (s mm). For type FSV consult us.

4.2. Coupling with end-cap

MOST COMPACT SOLUTION

Thanks to the high torque capacity and thecontinuous sleeve design, the Escogear Cand C... M couplings are the most compactanswer to any transmission applications. Incomparison to other types of couplings andfor a given torque they have a substantlylower weight and reduced outside diameter:

<–> Flanged Gear type : 17% smaller O.D.<–> Disc type : 30% smaller O.D.<–> Elastic type : 52% smaller O.D.

This compactness makes the Escogear Cseries ideal for use in applications wherespace is limited and weight important.

ADVANTAGES

WHY ESCODISC?

High Torque and Misalignment capacity

Thanks to the optimised disc shape and thickness (which could be obtained by infinite elementanalysis and laser cutting), the optimised number of bolts and the standard use of 12.9quality bolts, Escodisc couplings have a high torque and misalignment capacity combinedwith reduced reaction forces on connected equipment (bearings, mechanical seals....).

Infinite Life

All Escodisc coupligns have been calculated, designed and tested for infinite life. This ispossible thanks to the use of discs in AISI 301 stainless steel with special surface treatment,the standard use of fillers between the discs to eliminate fretting corrosion and the use ofhigh Safety margin on catalogue values.

No Buckling

In order to guarantee perfect centring of the spacer under all working condition (very importantfor long DBSE applications) and well controlled stresses in the disc pack, Escodisc couplingshave been calculated and tested to have no buckling up to the peak torque. This results introuble free operation, maximum efficiency and reduced risk for disc failure.

Flexible Spacer Design

Thanks to the unique design of the Escodisc spacer (flanges bolted to the intermediate tubesection – see catalogue drawings DMU/DPU). its length is easily adaptable to customerrequirements. Therefore quick delivery (even for non-standard DBSE) is possible and customerstock can be reduced to a minimum level.

Suitable for extreme temperatures and corrosive environment

Escodisc couplings can operate at temperatures as high as 270˚C and as low as -40˚C,(lower or higher temperature level on request). Furthermore, thanks to the use of stainlesssteel discs, the standard use of Dacromet protection for the hardware and a special surfacetreatment, Escodisc couplings are ideal for use in a corrosive environment.

Easy assembly and disassembly

To save cost at the assembly and the disassembly stages, the design of all Escodisc couplingshas been optimised (factory assembled disc pack or transmission unit, shipping screws...).

Torque transmission in case of disc pack failure

In the unlikely event of a disc pack failure, the Escodisc couplins have been designed in suca way that torque transmissions remains guaranteed for a limited time (through the bolts).This system furthermore keeps the spacer well centred and works as an anti-fly systemthrough which optimum user safety can be assured.

1. MISALIGNMENT CAPACITY

ESCODISC COUPLING CAN ACCOMMODATE 3 TYPES OF MISALIGNMENT:

Axial displacement: Angular misalignment: Offset misalignment:

da mm per coupling α degree per half coupling: dr mm per coupling

∆Ka= max. axial displacement α = max. (α1' α2) ∆Kr= max. offset misalignment

(see data sheet) ∆Kw = max. angular misalignment (see data sheet) (∆Kr=S tg ∆Kw)

(see data sheet)

Max. combinedmisalignment during operation iscalculated by using the graph:

In case of use in potentionally explisive atmospheres , European Directive 94/9/EC,the combination of misalignement may not exceed 0,8.

At assembly, we however recommend not to exceed 20% of the complete misalignment capacity of the coupling,See installation and maintenance instructions (IM).

2. TORQUE CAPACITY AND SELECTION

2.1 Tabulated torques are independent from misalignment and speed conditions as far as combined misalignment is within thespecified values (see above) and speed does not exceed tabulated values.

2.2 How to select?

A. First select the size of ESCODISC coupling that will accommodate the largest shaft diameter.

B. Make sure this coupling has the required nominal torque capacity according to the formula: Torque in Nm=

Where P = Power in kW, n = speed in min-1

Fu = Service factor depending on the connected machine (see below).

F = 1,5 in case of use in potentionally explosive atmospheres . In normal atmospheres, F = 1.

The coupling selected per A must have an equal or greater nominal torque capacity Tn (see planographs A104 to A121) thanthe resultof the formula B. If not, select a larger size coupling.

C. Check that the selected coupling has the required peak torque capacity according to the following formula:

Calculated peak torque = Peak torque of the application x F ; F , see above (Point B).

For application with direct starting of an AC motor, the transmitted peak torque has to be calculated with the following formula:

Calculated Peak Torque =

Peak torque capacity Tp of the coupling (see planographs A105 to A121) must be higher than the calculated peak torque. If not, selecta larger coupling.

D. Check if shaft/hub assembly will transmit the torque. (If in doubt, please consult Fenner Power Transmission).

E. Read carefully assembly and maintenance instructions.

The General Purpose High Torque/High Misalignment Solution

Maximum torque capacity: up to 260000 Nm – Bore Capacity: up to 370 mm

General Purpose Design

Because of the high torque, bore and misalignment capacity of the Escodisc DMU couplingrange, its high degree of natural inherent balance (AGMA class 9) up to size 85 and the factthat it meets the API 610 standards, this coupling is the ideal solution in a multitude ofapplications up to 260000 Nm (and larger upon request).

Unitised Disc Pack

The DMU disc pack consists of an optimised number of discs or separated links (for sizesgreater or equal to size 190) and has been factory assembled for easy field assembly. Toeliminate fretting corrosion (which limits disc type coupling life), stainless steel fillers betweenthe discs are used.

Close Coupled Design

The Escodisc DMU coupling is also available in close coupled design (DMUCC). The hightorque/bore capacity makes it an ideal maintenance free alternative for close coupled gearand elastic type couplings and can be modified in such a way that replacement of gear andelastic couplings is possible without axial displacement of the connected machines.

1. Introduction

Coupling must be selected properly according to selection charts. These documents are available in coupling catalogue or on our web site"www.escocoupling.com". Maximum misalignment figures at assembly are given is this document (see point 4: assembly). Max misalignmentfigures in operation (combination of radial, angular and axial) are given in catalogue. Max misalignment values may not be applied simultaneously.

as mentioned in selection. It is customer's responsibility to size and manufacture it properly to guarantee safe torque transmission and absence ofunbalance that could affect the life of the coupling and the connected machines. It is customer's responsibility to make sure that hub length, boresize and machining tolerances will transmit the torque. It is customer's responsibility to make sure that interference and machining tolerances willtransmit the torque and not exceed hub material permissible stress. The hubs must be axially secured on the shaft by means of a setscrew, an endplate or a sufficient interference. It is customer's responsibility to size and manufacture it properly to guarantee safe torque transmission andabsence of unbalance that could affect the life of the Discs. It is customer responsibility to protect the coupling by p.ex. a coupling guard and tocomply with the local safety rules regarding the protection of rotating parts.

2. Preparation

Ensure the conformity of the supplied equipment:

– Verify coupling size and conformity (see catalogue or web site).

– Identify any damaged and/or missing parts.

– Verify conformity of the coupling/machine interfaces.

Coupling original protection allows for storage indoors dry 18 months, indoor humid 12 months, outdoors covered 9 months and outdoors open3 months. For longer periods, it is customer responsibility to protect the parts properly. Instructions are a psrt of the supply of the coupling. Besure valud and complete assembly, operation and maintenance instructions are available. Make sure they are well understood. Assembly,disassembly and maintenance must be performed by qualified, trained and competent fitters. Before starting with assembly, disassembly andmaintenance, verify the availability of the tooling necessary.

– To manipulate the parts – To assemble the interfaces – To align the coupling– To tighten the screws and nuts

3. Warnings

Before removing the coupling guard and proceeding with any assembly, operation or maintenance operation of the coupling, make sure thecomplete system is completely shut down and definitively disengaged from any possible source of rotation, such as, for example:

– Electrical power supply – Any loss of braking effect.

Make sure everyone attending the equipment area will be properly informed (for example by means of warning properly located) about themaintenance or assembly situation.

In case of use in explosive atmospheres , specific protective measures must be considered. They are described in an extra

attachment (IM/A100-Ex) to the actual instructions with the couplings marked .

4. Assembly

4.0. WARNING

4.0.1. The hubs (1) and the spacer (4) are supplied unassembled. The disc-packs (3) are supplied packed with the screws (2) and nuts (5)under plastic film to ensure a perfect protection. They will only be unpacked during final mounting on the machine.

4.0.2. If coupling is supplied rough bored, bore and keyway must be machined in hubs (1). When machining the bore, surface marked (M)must be taken as the turning reference.

4.1. ASSEMBLY

4.1.1. Ensure that parts are clean and mount the hubs (1) in the correct position on the shafts of the machines (the flange at the shaft end).Hub faces must be flush with shaft end. In case of doubt, please consult us. Introduce setscrew on key with Loctite and tightenproperly.

4.1.2. Position the machines to be connected and check distance G between the hubs (fig. 1). See tabulation or approved drawing fordistance G following type of coupling. In case of doubt, please consult us.

4.1.3. Align the shafts using an indicator. The alignment precision (X, Y–Z) is given in the tabulation.

4.1.4. Ensure that the flanges of the hubs (1) and the spacer (4) are perfectly degreased. Unpack the discs and the screws. Mount the disc-pack (3) on one hub (1) with screws (2) and nuts (5) in the direction shown on the fig. 2. Tighten to torque T mentioned while holdingthe screws still and turning the nuts. See tabulation for tightening torque (T Nm) and socket size (s mm).

4.1.5. Install the spacer (4) between the hubs and connect it to the already assembled disc-pack (3) with screws (2) and nuts (5), in thedirection shown on the fig. 3 (in case of long spacer, it is essential to support the spacer in position from the beginning to the endof the assembly). Tighten to torque T mentioned in the tabulation while holding the screws still and turning the nuts.

4.1.6. Engage the second disc-pack (3) between the spacer (4) and the second hub (1) and assemble with screws (2) and nuts (5) asindicated in fig. 4.

4.1.7. Check once again the alignment by measuring the max. value H1 and the min. value H2 of the distance between the hub flange andthe spacer flange (see fig 5). See tabulation for the permissible values.

5. Operation, inspection and maintenance

5.1. OPERATION AND MAINTENANCE

No maintenance is necessary. It is however recommended to verify the alignment (see point 4.1.7.) and the tightening torque of thescrews (2) and nuts(5) (see tabulation) after the first running hours. Every 6.000 hours or 12 month, inspect external discs of disc pack forany fatigue crack and verify alignment.

5.2. DISASSEMBLY AND INSPECTION

Every 12.000 hours or every 24 month.

5.2.1. Remove the screws (2) and nuts (5) each side.

5.2.2. Remove the spacer (4) and inspect the discs (3). In case of damage, the disc-pack (3) must be replaced.

The easy to assemble High Torque/High Misalignment Solution

Maximum torque capacity: up to 23100 Nm – Bore Capacity: up to 220 mm

Easy assembly and disassembly

Thanks to the standard use of shipping screws and the factory assembled transmissionunit, Escodisc DPU couplings combine the high torque and misalignment capacity of theDMU couplings with easiness of asssembly. On average users can cut down assembly anddisassembly costs by 50% when using Escodisc DPU couplings. Furthermore, becausethe transmission unit is factory assembled, the risk for assembly errors is reduced to anabsolute minimum level which results in reliable operation and extended life of the coupling.

High Speed/Long DBSE applications

Thanks to the concept of the DPU coupling range (centering spigots) and the highmanufacturing standards, it is ideal for use in medium to high speed applications with no orminor modificatios. Furthermore, thanks to the perfect centering of the transmission unit,it can be used in applications where a long DBSE is required (e.g. cooling towers) and it canbe adapted to meet the API 671 requirements.

Large Bore Capacity

The Large Hub execution (L-hub) of the Escodisc DPU series makes selection virtuallyindependent of the shaft size which makes it possible in several applications to downsizecompared with DMU type couplings.

BALANCING

BALANCING OF ESCODISC COUPLINGS

1. Balancing

The actual requirement for balancing of a coupling depends amongst other on:

– Manufacturing quality of the coupling (Natural Inherent Balance Quality)

– Application speed

– The mass of the coupling (relative to the masses of the machine rotors)

– Distance between shaft ends

– Sensitivity of the system

Thanks to their high manufacturing quality, escodisc couplings have a high degree ofnatural inherent balance and generally don’t require additional balancing for normal speedapplications. Up to size 95, Escodisc DMU/DPU couplings have a minimum balancequality of Q6.3 at 1500 rpm. For larger sizes, Q6.3 is guaranteed without any additionalbalancing until 1000 rpm. In the below graph you can find when additional balancing isrequired based on application speed and DBSE. Also you can find the maximum limitsfor high speed/long DBSE applications based on the coupling size. Above these limits,please consult us.

2. Esco Balancing Procedures

Based on the application data or specific customer requirements, Fenner Transmissionswill perform a component blancing to Q6.3 or Q2.5 (as specified – Q1 is obtainable yetnot advisable for standard couplings) for standard couplings and a component balancingfollowed by an assembly balancing procedure for high speed applications. Other balancingoptions are of course available upon request but must be clearly specified when ordering.

Remark: for DMU couplings, only component balancing is possible.

ESCODISC SERIES DPU

1. Introduction

Coupling must be selected properly according to selection. These documents are available in coupling catalogue or on our web site"www.escocoupling.com". Maximum misalignment figures at assembly are given is this document (see point 4: assembly). Max misalignmentfigures in operation (combination of radial, angular and axial) are given in catalogue. Max misalignment values may not be applied simultaneously.In case of any change or adaptation not performed by ESCO on the coupling, it is customer responsibility to size and manufacture it properly toguarantee safe torque transmission and absence of unbalance that could affect the life of the coupling and the connected machines. It is customer'sresponsibility to make sure that shaft and key material, size and tolerance suit the application. Maximum bore capacity is given in the catalogue. Itis customer's responsibility to make sure that hub length, bore size and machining tolerances will transmit the torque. It is customer's responsibilityto make sure that interference and machining tolerances will transmit the torque and not exceed hub material permissible stress. The hubs mustbe axially secured on the shaft by means of a setscrew, an end plate or a sufficient interference. It is customer's responsibility to size andmanufacture it properly to guarantee safe torque transmission and absence of unbalance that could affect the life of the Discs. It is customerresponsibility to protect the coupling by p.ex. a coupling guard and to comply with the local safety rules regarding the protection of rotating parts.

2. Preparation

Ensure the conformity of the supplied equipment:– Verify coupling size and conformity (see catalogue or web site).– Identify any damaged and/or missing parts.– Verify conformity of the coupling/machine interfaces.Coupling original protection allows for storage indoors dry 18 months, indoor humid 12 months, outdoors covered 9 months and outdoors open 3months. For longer periods, it is customer responsibility to protect the parts properly. Instructions are a part of the supply of the coupling. Be surevalid and complete assembly, operation and maintenance instructions are available. Make sure they are well understood. Assembly, disassemblyand maintenance must be performed by qualified, trained and competent fitters. Before starting with assembly, disassembly and maintenance,verify the availability of the tooling necessary.– To manipulate the parts – To assemble the interfaces – To align the coupling – To tighten the screws and nuts

3. Warnings


4. Assembly

4.0. WARNING

4.0.1. The pack sub-assembly (1) including flange DP (1.1) discs (1.2), sandwich flange (1.3) and bolts and nuts (1.4) has to be considered asone single component. Bolts have been factory tightened for optimal torque transmission and infinite life. It may not be disassembled.Any external intervention to this sub-assembly (torquing bolts and nuts, seperating components) will automatically cancel suppliersguarantee, customer being fully responsible of any operation risk and damage.

4.0.2. The pack sub-assembly (1) is supplied compressed and fixed by shipping screws (15). This arrangement protects the flexible discsduring storage and shipment and makes assembly easier. These shipping screws (15) must be removed at assembly and beforestarting the machines (see pont 4.1.5.)

4.0.3. If coupling is supplied rough bored, bore and keyway must be machined in hubs (8) and (9). When maching the bore, surface marked(M) must e taken as the turning reference.

4.0.4. It is customer’s responsibility to protect the coupling and to conform his equipment to local safety legislation.4.1. ASSEMBLY

4.1.1. Install hubs (8) and (9) on their respective shafts in their proper position (see fig. 6). Hub faces must be flush with shaft end. In case ofdoubt, please consult us. Introduce setscrew on key with Loctite and tighten properly.

4.1.2. Position units to be connected and check distance G between the hubs. See tabulation or approved drawing for correct distance G,according to coupling type. In case of doubt, please consult us.

4.1.3. Align the two shafts using an indicator. Alignment precision (X and Y–Z) is given in alighment tabulation (fig. 6).4.1.4. Ensure that both spacer ends (2) and DP flange (1.1) are perfectly degreased. Mount (see fig. 2) hub sub-assemblies (1) and spacer (2)

with screws (3) and washers (4). Tighten screws (3) uniformly (tighteneing torque T3). See tabulation for correct tightening torque(Spacer T3 Nm) and key size (s mm).

4.1.5. Ensure that both hubs faces (8) and (9) and sandwich flange (1.3) are perfectly degreased. Introduce floating assembly between thetwo hubs (fig. 3). Remove the shipping screws (15) with rings (17) and shipping inserts (16) at each end (fig. 4). The floating assemblymust be maintained in position by the two hubs (8) and (9). If not, the distance between the hubs and (or) the alignment are wrong andmust be corrected (see points 1.3 and 1.4).

4.1.6. Engage the 6 screws (5) and rings (6) or the 6 screws and washers (7) in each hub (fig. 5). Tighten the screws (5) or (7) uniformly(tightening torque T5). See tabulation for correct tightening torque (Hubs T5 Nm) and key size (s mm).

4.1.7. Check once again the alignment and axial distance by measuring the max. value H1 and the min. value H2 of the distance betweenflange DP (1.1) and sandwich flange 1.3 (see gigure). See tabulation for the permissible values.



No maintenance is necessary. It is however recommended to verify the alignment (see point 4.1.7.) and the tightening torque of the screws(5) (see point4.1.6.) after the first running hours. Every 6.000 hours or 12 month, inspect external discs of disc pack for any fatigue crack andverify alignment.


Every 12.000 hours or every 24 month.5.2.1. Remove the 6 screws (5) or (7) (according to the case) each side. Introduce the shipping screws (15) and shipping inserts (16) and

tighten the screws (15) to compress pack sub-assembly (1). Note that the minimum distance H0 in stationary condition between flangeDP (1.1) and sandwich flange (1.3) should never be less than H0 given in tabulation.

5.2.2. Remove floating assembly (2) and inspects discs (1.2) without dismounting hub sub-assembly (1) (see point 4.0.1). In case of damage,complete sub-assembly (1) must be replaced.

ATTACHMENT : Specific Protective Measures for ESCODISC Couplings in case of use in explosiveatmospheres.

0. Introduction

General assembly and maintenance instructions are established for standard ESCODISC couplings.In case of use in potentially explosive atmospheres, further to the general assembly and maintenance instructions, the specific measures describedin this attachment must be taken.

1. Coupling Selection

The coupling must be selected according to the general assembly and maintenance instructions.In explosive atmosphere, the following specific rules must apply:A Service Factor of 1.5 must be applied on the max torque values for nominal torque (Tn) and peak torque (Tp) given in the tables.

2. Use of the coupling

The coupling is dedicated for use in potentially explosive atmospheres according to European Directive 94/9/EC (Atex 100 A).Coupling is classified in equipment group II, equipment catetgory 2 and 3, intended for use in areas in which explosive atmospheres caused bygases, capours, mists of air/dust mixtures are likely to occur.In function of the ambient temperature in the coupling proximity (85,55, 45˚C), the temperature classes have been defined (T4, T5, T6).This is based on a temperature increase of the machine shafts (in regard of the ambient temperature) that will not exceed 50˚C in operation.The coupling is marked as follows: CE 11 2G T4/T5/T6 D 120˚C –20˚C � Ta � 85˚C / 55˚C/ 45˚C

3. Warnings

The warnings mentioned in the general asssembly and maintenance instructions must apply in any case.In explosive atmosphere, the following specific warnings must apply:• Complete machining of the coupling parts (bores, keyways, spacers, floating shafts etc...) must be performed by ESCO transmission N.V.

No modification shall be made on the supplied and marked product without the agreement of ESCO Transmissions N.V.• Before proceeding with any assembly, operation or maintenance operation on the coupling, make sure that the necessary measures have

been taken to ensure safety, such as but not limited to:� Proper ventilation of the area � Proper lightening and electrical tools

• If hub must be heated for assembly on the shaft, make sure heating source and surface temperature will not affect the safety of the workingarea.

• It is recommended to have a strong coupling guard, preferably in stainless steel with openins (if any) smaller than the smallest centrifugablepart (nut is 10mm dia.). The coupling guard is intended to protect the environment from the centrifugation of any rotating part and therotating coupling from any falling part. To limit ventilation effects, distance between cover and coupling outside surface should be at least10mm.

4. Assembly

The general assembly and maintenance instructions must apply in any case.In explosive atmosphere, the following specific instructions must apply:Alignment of the machine in cold condition must take into account the possible heat expansion to make sure that in continuous runningconditions, max misalignment calculated on the base will not exceed 80% of the max allowed value:Da/∆ka + α/∆kr +dr/∆kr � 0.80.

5. Operation

The general assembly and maintenance instructions must apply in any case.In explosive atmosphere, the following specific instructions must apply:• Before Start-up

� Make sure coupling is perfectly clean and properly aligned. � Make sure, screws, nuts are properly tightened.� Coupling guard must be properly installed and fixed. � Monitoring system, if any, must be tested to verify its effectiveness.

• During Start-up� Check for any abnormal noise and/or vibration. If any, immediate stop is mandatory and appropriate action must be taken.
