DECOUPLING DEVICE FOR MOUNTING A SHAFT ON A BASE AND RADIAL UNDULAR WASHER

摘要

Disclosed is a decoupling device for mounting a shaft, particularly the shaft of a spherical-disk-shaped enveloping gear operating with a chain as an enveloping means, on a base. The inventive decoupling device comprises an outer bearing ring (4) which has a circular cylindrical outer surface (14) and inside which the shaft is mounted, and an inner surface which is rigidly connected to the base and surrounds the outer surface. At least one radial undular washer is disposed between the outer surface and the inner surface (16). Said radial undular washer allows the inner surface and the outer surface to be radially moved relative to each other to a limited degree while being elastically deformed.
