Torsion vibration damper for machine parts limiting gap

摘要

The damper has a spring body (4) which is arranged in the gap enclosed by the two machine parts (2,3), consists of elastomer material and has at least two half surfaces fixed to one of the machine parts. The other opposing surfaces of the spring body and machine parts are formed by guide surfaces, which are spaced apart. The intermediate space (8) formed by the spacing is fluid-tight and filled with a viscous fluid (9). The intermediate space is formed by a shrink gap (10) and has a wave-shape when observed in a peripheral direction. The machine part limited by the shrink gap and the spring body have on the facing sides a congruently formed surface profiling (11,12).
