ZIMMER Industrial Shock Absorbers
The Spiral Groove as Damping Principle…
In contrast to the customary industrial
impact damper the exhausting channel (throttle) is directly incorporated
in the piston. By its continuous spiral groove there is a dynamic force
over the total stroke and a maximum energy absorption at minimum power. A
lubricating film in the form of a hydrostatic slide bearing is built up
between the piston and high-pressure tube. The technological improvement
is evident.
…and its advantages:
•
Smooth deceleration without cross section constrictions.
•
Higher power absorption through use of maximum capacity in each piston
position.
•
Small construction space by substantial higher energy absorption.
•
Minimum consumption rates by optimal bearing.
•
Insertion in pneumatic pressure chamber possible.
•
Higher operation safety and increased operating life.
Characteristics:
 Customary
Design
An industrial impact damper of conventional design squeezes the oil out by
the throttle bores which are inserted on one side of a tube. The oil is
force-diverted and enormous strain is generated by the high velocities of
impact. The vibrations produced drastically effect the life of the
elements involved in the damping process.
 New
and Improved Design
Zimmer GmbH incorporated the exhausting channel directly in the piston as
a spiral grove. During the damping process mechanical strain of the oil
remains low because of the rotary spiral groove. The result is maximum
energy absorption over the entire damping stroke and guarantees a smooth
damping process.
Hydrostatic Piston Guidance by Spiral Groove Technology
The piston of the PowerStop driving into the oil bath, produces during the
damping process, a hydrostatic slide bearing between the piston and tube
by the symmetric axis of the integrated spiral groove. The sliding film
separates the movable elements during the damping process. The result is
high life expectancy, maintenance-free operation and the guarantee of a
high production safety. |
