Abstract:
1. A bearing assembly for a continuously variable transmission for rotatably supporting a rotatable member, said bearing assembly comprising: an outer bearing ring and an inner bearing ring, wherein the outer bearing ring is adapted to be axially secured in a stationary bearing retainer having a substantially cylindrical inner wall, and a vibration damping device including a resilient member that is flexible in a radial direction and positioned between an outer peripheral surface of the outer bearing ring and the substantially cylindrical inner wall of the stationary bearing retainer, wherein the resilient member includes a pair of axially spaced, connected annular bands and a plurality of circumferentially spaced radially inwardly projecting and substantially axially extending, elastically deflectable formations positioned between the annular bands and arranged on substantially the entire circumference of the annular resilient member, the resilient member including connecting regions positioned between the circumferentially spaced formations for connection with the annular bands, wherein the annular bands contact the substantially cylindrical inner wall of the stationary bearing retainer and the radially inwardly projecting formations contact the outer bearing ring, wherein the stationary bearing retainer includes at least one inner, substantially-axially-extending annular edge that is spaced radially inwardly of the bearing retainer cylindrical inner wall and radially outwardly of the outer peripheral surface of the outer bearing ring, for limiting outward radial displacement of the outer bearing ring upon radial deflection of the resilient member, and flexible elements disposed against the outer bearing ring for damping axial vibrations of the outer bearing ring.
