At our PowerStop the exhausting channel (throttle) is directly incorporated into the piston compared to the conventional shock absorber. Because of the continious conicity (spiral groove) of the piston there is a dynamic force over the total Stroke and a maximum energy consumption at minimum power.By the spiral groove a lubricating film in form of a classical hydrostatic slide bearing is built up between the piston and high-pressure bushing. The technogical improvement is evident.

• smooth braking (without sudden cross section constrictions)

• higher power consumption by max. capacity use in each piston position

• individual manual adjustment for each matter of application

• compact construction space by substancial higher energy consumption

• minimum abrasion rates by optimal bearing

• assembly in pneumatic pressure chamber possible (PowerStop)

• higher operation safety and longer service life by oil reserve (PowerStop)

Ideal Damping Characteristic

An industrial shock absorber of conventional design squeezes the oil out by the throttle bores which are inserted on one side of a bushing. The oil will be force-diverted and enormously strained by the high velocities of hitting.Pressure peaks are producing vibration and are reducing the service life of elements involved at the damping process. The damping behaviour will be destinated by the number of throttle bores, the energy consumption is restricted.

The exhausting channel of the PowerStop is directly inserted in the piston as spiral groove. During damping the piston dives into the oil bath and picks up over the exhausting channel the oil to be squeezed. The mechanical strain of the oil remains low because of the rotary rising spiral groove. The section form allows a continuous throttle activity and guarantees a smooth damping. The result is a maximum energy consumption across the entire damping Stroke!

Damping with Spiral Groove Technologyconvetional

The new Damping curveThe PowerStop approaches with its damping course to the ideal line of an industrial shock absorber. By the special sectioned groove a smooth energy absorbtion will be started, the variation of the braking power is low. So, an exact positioning will be ensured also with extreme quick damping cycles with a short Stroke.

The characteristic curve of the spiral groove shows a continious course of the throttle cross-section over the entire piston Stroke. By this, in each piston position an ideal limiting is realized and the energy consumption optimized . The masses to be moved can be smoothly and safely positionned, also with slow speeds. A further important advantage results by the STROKE-COURSE-ADJUST-MENT. In case the screw-in depth will modified, the damping cha-racteristic can be adapted individually to matter of application.Throttl bores, however, are producing a graduated characteristic curve with strong variations in the energy consumption!

By the spiral groove technology the energy consumption will be tripled in comparison to the conventional type with throttle bores (under comparable test conditions). The diagram shows the energy consumption at the example of construction series:M33 x 1.5, Stroke 30mm!

result:• higher energy consumption• smaller construction series

Triple Energy Absorption

Hydrostatic Piston Guidance by Spiral Groove TechnologyThe piston of the PowerStop diving in the oil bath produces during damping process a hydrostatic slide bearing between piston and bushing by the symmetric axis of the in-tegrated spiral groove. The sliding film separates the movable elements during damping process. High service life expectancy, maintenance-free and reliability guarantee a high production safety.

Industrial shock absorber for the employment under constant load. High energy consumption, small design, durability and the possibility of insertion in pneumatic pressure chamber distinguish the PowerStop.

Industrial shock absorber for the employment as Emergency Stop. Very high energy consumption at optimal damping behaviour. Not suitable for a constant load by continual recurring loading cycles.

Design with long Stroke

Typ W (SUPER SOFT) Execution for high velocities of hitting. For decelerating without pressure peaks.

Typ S (SOFT) Execution for high velocities of hitting. Preferably at free falling masses.

Typ M (MEDIUM) Execution for medium velocities of hitting. Employment, e.g. at quick pneumatic drived masses.

Typ H (HARD) Execution for slow velocities of hitting. Employment at slow (reduced) movements.

Executions:

The wide spectrum – low speeds at big masses upto quick speeds at small masses – at same ener-gy consumption per Stroke is subdivided into three groups.

Note: Generally all shock absorbers can be customized to non-standard requests!

Examples:

Special designs

The spiral groove technology even more effective with our new product range of PowerStop type „W“:

high velocities of hitting will be damp with extremely low supporting forces and bounce-free.

different from accepted throttle bore damping, the PowerStop „W“ is able to damp without pressure peaks.

Up to 100mm more traverse path with the EmergencyStop I-Class. The EmergencyStop i-Class (I=intelligent) now enables you to process larger components with the same machine. While approaching the absorber the supporting power complies only with the value of the spring for relocating the piston.In the case of an EmergencyStop the machine's damping effect is executed as usual. The power absorption complies with the shock absorbers of the standard EmergencyStop series.

More security for your machinery:PowerStop with oil alarm.The integrated oil reserve of our PowerStop guarantees a higher number of cycles as well as a longer service life. In case the oil reserve run short, a signal at the control panel indicates that the absorber has to be exchanged.

Stop SleeveThe PowerStop can not be used as an arresting stop. It must be integrated into the construction or a stop must be used sleeve.Through the stop sleeve the final stop can be adjusted individually for each application. By this, the impact damper will be fix screewed into the connecting construction. The adjusting follows by the arresting sleeve and the counternut.

Plastic Head/Steel HeadBy using a steel head the surface hit with load will be enlarged (minimization of surface load).This accessory mainly is applicated for soft counter material (aluminium)of the movable carriage, on applications for which the noise processing have to be reduced, we recommend the using of a plastic head. When using a head, this has to be glued on. To do so, we recommend to use Loctite fast cleaner 7063, Loctite activator set 7649 and Loctite retaining compound 638. Also available as gluing set (Order no. ZUB0055).

Cooler NutThe operation temperature should not exceed 70°C. The stated values (energy absorption/h) are relating to a vicinity temperature of 20°C. If a shorter cycle time is required, we recommend the application of a cooler nut. By the assembly of the cooler nut the PowerStop Damper can be used with a shorter cycle time. The energy absorption per hour of the impact damper can be increased to the double. Note: The maximum allowed energy absorption per Stroke may not be exceeded.

Bolt Pre-supporting/Air CurtainTwo requirements solved by one component.• If the impact angle is larger than 2°, a bolt pre-supporting must be adapted. This

allowes the impact angle to be increased up to 30°. We recommend the use of the bolt pre-supporting for swivelling moments with relative small swivelling radius.

• Applications with increased dirt volume, the use of a lock air adapter is to recommend. The lock adapter distinguishes by the low consumption of air. The penetration of dirt particles will avoided and guarantees, therefore, a longer service life.

The fi ne adjustment of the energy absorption is performed by manually changing the (screwed) position depending on each individual application (see Fig.).

The PowerStop is screwed into the construction (Fig.1) The PowerStop has to be positioned in a manner

which guarantees a remaining Stroke of 0.5mm – 1.0mm before the reach of the end stop.

The PowerStop has to be positioned step by step in the direction of rotation (Fig.2), in order to guarantee an optimal damping.This is achieved as soon as the damping velocity decreases linearly and reaches its minimum directly before impinging upon the mechanical end stop.

Locking of the counter nut resp. the stop sleeve, the cooling nut with required moment.

Operational Test

After the appropriate installation of the shock absorber the operating readiness has to be tested.The mobility of the piston rod has to be tested by manual movement.All attachment screws have to be checked for their required moment.The deviation from the angle adjustment of a 2° maximum has to be checked.Max. damping Stroke (Table 1) must not be exceeded.
