Decoupling device for mounting a shaft on a base and radial ondular washer

摘要

A decoupling device for the bearing arrangement of a shaft carried in a housing, in particular a shaft of a belt-driven conical-pulley transmission with a chain that functions as the belt. The decoupling device includes an outer bearing ring configured with a circularly cylindrical outer surface and within which the shaft is mounted, and an inner surface of a housing that encloses the bearing ring outer surface. At least one radial ondular washer is arranged between the bearing ring outer surface and the housing inner surface, which allows a limited relative radial movement between the housing inner surface and the bearing ring outer surface by elastic deformation of the washer.
