  • Patent number: 10161493
    Abstract: A power transmitting component that includes a housing, a case, a bearing, a bearing adjuster, and a retaining member. The housing defines a bearing bulkhead and an aperture, the aperture being disposed about a first axis. A pinion is coupled to the housing for rotation about a second axis that is not coincident with the first axis. A ring gear is coupled to the differential case and is meshed with the pinion. A bearing supports the case for rotation relative to the housing about the first axis. A bearing adjuster is disposed within the aperture and abuts the bearing. The retaining member is formed of a polymeric material and couples the bearing adjuster to the bearing bulkhead such that the bearing adjuster is non-rotatably and axially fixed to the housing and a preload is applied to the bearing in a direction along the first axis.

  • Patent number: 10161495
    Abstract: Mating bevel gears generally include a pinion gear having a body that rotates about an axis and a side gear having a body that rotates about an axis that intersects the axis of the pinion gear. Pinion gear teeth of the pinion gear have a side that defines a curvature with an involute section through which a pitch line extends and a parabolic shape between the pinion gear teeth. Side gear teeth of the side gear have a side that defines a curvature with an involute section through which a pitch line extends and a parabolic shape between the side gear teeth. The curvatures on the pinion and the side gear teeth cooperatively define a controlled relative radius of curvature section except where the involute sections are located. The controlled relative radius of curvature section defines a sum of values of radius of curvature at a point of contact between the curvatures of the pinion gear teeth and the side gear teeth. The sum has a constant or decreasing value.
