Abstract:
1. A decoupling device for a bearing arrangement for rotatably supporting a shaft in a housing, said decoupling device comprising an annular outer bearing ring configured with a circularly cylindrical outer surface and radially-extending lateral surfaces, within which bearing ring the shaft is rotatably mounted, a housing inner surface that surrounds the bearing ring outer surface, wherein at least one radially elastically deformable ondular washer is positioned between the bearing ring outer surface and the housing inner surface and which ondular washer allows a limited relative radial movement between the housing inner surface and the bearing ring outer surface, wherein on the outer surface and the radially-extending lateral surfaces of the bearing ring is fitted an annular spring sleeve that forms the radially elastically deformable ondular washer and has an overall U-shaped cross section that includes an axially-extending base having radially outwardly curving axial ends, and wherein an annular region of the ondular washer projects between the radially-extending lateral surfaces into a peripheral recess of the outer surface of the bearing ring.
