  • Patent number: 9593756
    Abstract: A bearing assembly and a related power transmitting component. The bearing assembly includes a first bearing, which is an angular contact bearing, and a second bearing, which is a tapered roller bearing. The first bearing has a first inner bearing race, a first outer bearing race and a plurality of spherical bearing balls disposed between the first inner bearing race and the first outer bearing race. The second bearing assembly has a second inner bearing race, a second outer bearing race and a plurality of tapered bearing rolls disposed between the second inner bearing race and the second outer bearing race. One of the first inner and first outer bearing races is fixedly coupled to one of the second inner and second outer bearing races for axial and rotational movement therewith. The first and second bearings are configured to handle thrust in a common axial direction.

  • Patent number: 8460149
    Abstract: A power transmitting component that includes a housing, a differential case, a ring gear coupled to the differential case for rotation therewith, a pinion gear meshed with the ring gear, a bearing mount, a differential bearing and a retaining ring. The housing has a bearing mounting aperture and a retaining ring groove. The bearing mount is received in the bearing mounting aperture. The differential bearing disposed is between the differential case and the bearing mount. The retaining ring is received into the retaining ring groove and is sized in thickness a) to control a pattern of mesh between the ring gear and the pinion gear, b) to maintain a predetermined preload on the differential bearings, or c) to control the pattern of mesh between the ring gear and the pinion gear, and to maintain the predetermined preload on the differential bearings.
