Acoustic decoupling device for roller bearing for bearing shaft of cone disk set in cone disk embracing gear in motor car, has axial middle area curved outward in convex manner along recesses that are arranged in distributed manner

摘要

The device (3) has an axial middle area (5) designed in a hollow cylindrical shape, and edge areas (6, 7) axially attached at the middle area, where the device is made of steel using deep-drawing method. The edge areas extend radially inward, and the middle area comprises recesses at a radial inner outer surface (4). The recesses extend in an axial direction, and are arranged in a distributed manner at the circumference. The middle area is curved outward in a convex manner along the recesses, and the edge areas exhibit non-uniform axial expansion. An independent claim is also included for a bearing that comprises rolling members.
