Sprockets for 815, 820, and 881 are all double duty. Sprockets with odd numbers of teeth are recommended for longer wear since a given tooth engages the chain every other revolution. Sprockets with 19, 21, 23, and 25 teeth are preferred. Sprockets with even number of teeth should be advanced one tooth periodically to attain even wear.

Safety
SafetySafety must be considered a basic factor in machinery operation at all times. Most accidents are the results of carelessness or negligence. All rotating power transmission products are potentially dangerous and must be guarded by the contractor, installer, purchaser, owner, and user as required by applicable laws, regulations, standards, and good safety practice. Additional specific information must be obtained from other sources including the latest editions of American Society of Mechanical Engineers; Standard A.N.S.I B15.1 It is the responsibility of the contractor, installer, purchaser, owner, and user to install, maintain, and operate the parts or components manufactured and supplied by Martin Sprocket & Gear, Inc., in such a manner as to comply with the Williams-Steiger Occupational Safety Act and with all state and local laws, ordinances, regulations, and the American National Standard Institute Safety Code.
WarningGuards, access doors, and covers must be securely fastened before operating any equipment. If parts are to be inspected, cleaned, observed, or general maintenance performed, the motor driving the part or components is to be locked out electrically in such a manner that it cannot be started by anyone, however remote from the area. Failure to follow these instructions may result in personal injury or property damage.

Stock QD BushingsThe Martin Quick Detachable bushings are easy to install and remove. They are split through flange and taper to provide a true clamp on the shaft that is the equivalent of a shrink fit. All sizes except JA and H have a set screw over the key to help maintain the bushings position on the shaft until the cap screws are securely tightened.
Removal1. Loosen and remove cap screws. 2. Insert cap screws in tapped removal holes. 3. Tighten inserted screws until sprocket is loose on shaft. 4. Remove sprocket from shaft.
Installation1. Be sure the tapered cone surfaces of the bushing and the inside of sprocket are clean.5 2. Place bushing in sprocket, sheave, pulley, or other Martin QD parts. On M through S bushings, the mating part and bushing MUST be assembled so the two threaded holes in the mating part are located as far as possible from the sawcut in the bushing. 3. Place cap screws and lock washers loosely in pull-up holes. Bushing remains fully expanded to assure sliding t on shaft. 4. With key on shaft, slide sprocket to desired position on shaft. Be sure heads of capscrews are on outside. 5. Align sprocket. Tighten screws alternately and progressively until they are pulled up tight. To increase leverage, use wrench or length of pipe (see wrench torque chart on pg. B-5). Do not allow sprocket to be drawn in contact with ange of bushing; there should be a gap of 18 to 14 inch.
STANDARD
REVERSE
CAUTION: When mounting screws, apply pressure by hand only. If extreme tightening forces are applied, bursting pressures will be created in the sprocket hub. There should be a gap of 18 to 14 between the face of the sprocket hub and the flange of the QD bushing. This gap must not be closed. If the gap is closed under normal tightening, the shaft is seriously undersized.
5 WARNING : USE OF ANTI-SEIZE LUBRICANT ON
TAPERED CONE SURFACES MAY RESULT IN DAMAGE TO SHEAVES AND SPROCKETS.

Stock QD BushingsREVERSE Mounting Assembly for QD Sheaves and Sprockets using JA, SH, SD, SDS, SK, SF, E, F, & J BushingsThese bushings, as well as the sprockets and sheaves for them, are each drilled with six holes (three drilled and three tapped) to allow pull-up bolts to be inserted from either side. This enables variations of mounting characteristics to suit a particular installation.
STANDARD MOUNTING
REVERSE MOUNTING
MOUNTING1. Assemble sheave or sprocket with bolts inserted (But not tightened) through DRILLED holes in bushing ange into TAPPED holes in sheave or sprocket. 2. With key in shaft keyseat, slide assembly into approximate position on shaft with ange end of bushing away from bearing. 3. Position QD bushing on shaft by tightening set screw over key hand tight with standard Allen wrench only. Do not use excessive force. 4. Tighten pull-up bolts alternately and evenly to tighteness indicated in torque table below. Do not use extensions on wrench handles. There should be a gap between the face of the sheave or sprocket hub and the ange of the QD Bushing to insure a satisfactory cone grip and press t. CAUTION: THIS GAP MUST NOT BE CLOSED.
DISMOUNTING1. Remove pull-up bolts and screw them into TAPPED holes in bushing ange and against hub of sheave or sprocket to break cone grip. 2. Loosen set screw in bushing ange and slide QD bushing from shaft.
Bushing Installation TorqueWhen a wrench or length of pipe is used to increase leverage in tightening bushing screws, it is imperative to adhere to the wrench torque values given in the chart below. This adherence is important because, in mounting the bushing, the tightening force of the screw is multiplied many times by the wedging action of the tapered surface. This action compresses the bushing for a snug t on the shaft. The bushing screws should always be tightened alternately and progressively.
Wrench Torque Values For Tightening BushingsQD Bushing Size Size of Cap Screw In. Lbs. to Apply With Torque Wrench Proper Wrench Pull With Open End or Socket Wrench Wrench Length Wrench Pull in Lbs.
CAUTIONA. Be sure cone surfaces are free of paint, grease and dirt. B. Tighten pull-up bolts alternately and evenly per bolt torque table. C. Never close gap between sheave or sprocket and ange of QD Bushing. WARNING: use of Anti-seize lubricant on tapered cone surfaces when mounting sheaves voids all mfg. warranties. See A, B, C on drawings.

To Install:1. Clean shaft, bore, and outside of bushing, and bore of hub (taking bushing from hub if already assembled). Remove any oil, lacquer, or dirt. Place bushing in hub and match half holes to make complete holes (each complete hole will be threaded on one side only). 2. Oil thread and point of set screws or thread and under head of cap screws. Place screws loosely in holes that are threaded on hub side (shown thus in diagram). 3. Make sure bushing is free in hub. Slip assembly onto shaft and locate in position desired. 4.Tighten screws (see note5) alternately and evenly until all are pulled up very tightly. Use a piece of pipe on wrench to increase leverage. (See table for wrench torque on reverse side.) 5. Hammer against large end of bushing using hammer and block or sleeve to avoid damage. Screws can now be turned a little more using the specified wrench torque. Repeat this alternate hammering and screw re-tightening until the specied wrench torque no longer turns the screws after hammering. Fill other holes with grease to exclude dirt.FOR INSTALLATION
FOR REMOVAL ONLY
Recommended Wrench TorqueBushing Number Screws Wrench Torquev (Pounds-Inches)
vWhen torque wrench is not available, it is possible to approximate these values by using an ordinary wrench and piece of pipe on wrench. For example, to obtain 1000 poundinches wrench torque, pull 100 pounds at 10 distance from center of pull to center of screw, or pull 50 pounds at 20 distance.

To Remove:1. Remove all screws. Oil thread and point of set screws or thread and under head of cap screws. 2. Insert screws in holds that are threaded on bushing side (shown thus in diagram). In sizes where washers are found under screw heads, be sure to use these washers. Note that one screw in each hub is left over and is not used in this loosening operation. 3. Tighten screws alternately until bushing is loosened in hub. If bushing does not loosen immediately, tap on hub.
When ordering Bushings give: Number stamped on large end of bushing, bore, and quantity. 5If two bushings are used in the same sheave, pulley, or other unit member, tighten one bushing on shaft per steps 4 and 5 before starting to tighten screws in other bushing.

Taper Bushed Type S-Type W Weld-On Hubs DimensionsMartin Taper Bushed Type S Weld-On Hubs are suitable for use in many applications such as for welding to plate steel sprockets. The outside diameters of these hubs have been reduced to a minimum. This is permissible because of the reinforcing strength of the items to which they are to be welded. Cases where the attached item is of small dimensions should be referred to Martin.Type S Weld-On Hubs are made of steel, drilled, tapped, and taper bored for Tapered Bushings. Their small size and the convenience and advantages of Taper Bushed construction make them of great value on many devices for use on shafts.

ParallelQUADRA-FLEX couplings absorb parallel misalignment without wear and with minimal loss of energy. The amount of parallel offset handled varies by size from .015 on the size 5 up to .062 on the size 16. This minimizes the radial loads on bearings when parallel misalignment occurs.
AngularDue to the exing characteristics of the sleeve and the locking action of the teeth, QUADRA-FLEX couplings easily handle angular misalignment up to 1 degree without any appreciable wear.
TorsionalQUADRA-FLEX sleeves are torsionally resilient and are well suited to absorbing shocks and dampening vibrations that would otherwise be transmitted between the equipment.
AxialThe axial flexibility of the sleeve allows the QUADRAFLEX coupling to accept a limited amount of end float. This serves to reduce thrust loads transferred to bearings. QUADRA-FLEX units will accept axial movement of approximately 1/8.

QUADRA-FLEX couplings come in a variety of styles and designs to meet specific customer needs. These include flanges and sleeves of various types and materials. The total product line includes 13 sizes varying in torque ratings up to 72,000 in-lbs. When ordering QUADRA-FLEX couplings, the following basic procedure should help expedite order processing. For coupling anges, give the basic coupling size, then the letter for the type ange followed by the bore size required. For coupling sleeves, give the coupling size followed by the letter(s) designating the type and material required. (See above) The following are various examples for reference: Example: Type J Flange Size 5 7 Flange J S Bore 3 4 30mm

Sleeve SelectionQUADRA-FLEX coupling sleeves are available in four different types of compounds. These include TPR (ThermoPlastic Rubber) in types JEM, JEMS, EM; EPDM Rubber in type E; Neoprene in type N; Hytrel in type H and HS. To determine the sleeve best suited for the application, the material characteristics are given below.
TPR(Sizes 3-10)QUADRA-FLEX couplings are usually supplied with TPR sleeves in sizes 3-10. TPR is a general use sleeve which combines the characteristics of both EPDM & Neoprene into one. These sleeves operate within a temperature range from -50 F to +275 F (-46 C to +135 C). Torsional exibility is 15.
EPDM(Sizes 11-16)QUADRA-FLEX couplings are usually supplied with EPDM rubber sleeves in sizes 11-16. EPDM is a general use sleeve and can operate within a temperature range from 30 F to +275 F (-34 C to +135 C). Torsional flexibility is 15.
NEOPRENE5(Sizes 13-16)Neoprene exible sleeves are also available in sizes 11-14. These sleeves offer a higher resistance than EPDM and are self-extinguishing. Operating temperature range for this sleeve is 0 F to +200 F (-18 C to +93 C). Torsional exibility is 15.
HYTREL5(Sizes 6-14)Hytrel sleeves are molded specifically for high torque applications. The type H will transmit approximately four times as much power as an equivalent TPR, EPDM, or Neoprene sleeve. Hytrel has an operating temperature from 65 F to +250 F (-54 C to +121 C). Torsional exibility is 7. Note: Do not use a Hytrel sleeve as a replacement for a TPR, EPDM, or Neoprene sleeve.

Selection ProcedureSelection ProcedureWhen the driver is an electric motor with standard speed. Step 1. Determine Service Factor (SF) Symbol based on equipment listed on page C-10. Step 2. Determine proper Service Factor from chart at top of page C-10. Step 3. Refer to page C-12 and C-13 for proper selection of coupling. Based on chemical resistance and operating environment found on page C-8, select from chart the type of sleeve material. Find RPM of motor, then, in the column for service factor determined in Step 2, read down to the corresponding horsepower of motor being used as the driver. The number listed is the correct coupling size. Example: A coupling is needed to connect a 25 HP standard electric motor to a lumber log haul at 1750 RPM. 1. Service Factor Symbol H 2. Service Factor 2.0 3. Coupling Size 9 with TPR sleeve or 6 with Hytrel Sleeve Step 4. Select flanges from pages C-13 thru C-16, check coupling bore size range for proper shaft t. When the driver is other than an electric motor or the speeds are different than those shown in the chart on pages C-8 and C-9. Step 1. Follow steps 1 & 2 in previous procedure. Step 2. Calculate Horsepower at 100 RPM as follows: HP at 100 RPM = HP x Service Factor x 100coupling RPM
Step 3. Select coupling size from Table 2. Find a HP equal to or greater than the HP/100 RPM Step 4. Check Maximum bore to be sure that both shaft sizes do not exceed figure listed for size selected in step 4. If maximum is exceeded select the next largest size which will allow for bore size. Do not exceed maximum RPM for new size selected. Example: A bucket elevator is driven by a motor/reducer and requires a coupling to transmit 14 HP at 1300 RPM. 1. Service Factor Symbol M 2. Service Factor 1.5 3. HP at 100 RPM = 14 x1.5 x 100 = 1.61 HP/100 RPM1300
5 NOTE: Do not oversize coupling hub will cause premature wear of element.
4. Refer to page C-11; under column for 100 RPM the required 1.61 HP falls between the size 7 (1.2) and the size 8 (1.8). Correct selection is size 8 with TPR sleeve. Check bore sizes for anges on pages C-11 thru C-13.
