Abstract:
1. A ring gear, comprising: a cylindrical ring gear body having a wall with opposing first and second ends and a longitudinal length extending therebetween, the wall having a radially outer surface and a radially inner surface, wherein the inner surface has a first portion that extends a first sub-length of the ring gear body and a second portion that extends a second sub-length of the ring gear body, wherein the inner surface of the wall of the ring gear body comprises a circumferentially extending rim positioned longitudinally between the first and second portions of the inner surface of the wall of the ring gear body and configured to longitudinally space apart the first and second portions, wherein the first portion of the inner surface of the wall of the ring gear body extends from the first end of the ring gear body to the circumferentially extending rim and the second portion of the inner surface of the wall of the ring gear body extends from the second end of the ring gear body to the circumferentially extending rim, wherein the first portion of the inner surface of the wall of the ring gear body comprises a plurality of longitudinally extending splines and the second portion of the inner surface of the wall of the ring gear body is devoid of the splines, and further wherein the second portion of the inner surface of the wall of the ring gear body comprises at least one of: (a) longitudinally extending slots that extend in an axial direction along the second sub-length of the second portion of the inner surface of the wall of the ring gear body from the circumferentially extending rim to the second end of the wall of the ring gear body; (b) radially inward projecting, longitudinally extending rails that extend in an axial direction along the second sub-length of the second portion of the inner surface of the wall of the ring gear body from the circumferentially extending rim to the second end of the wall of the ring gear body; or (c) at least one each of a longitudinally extending slot and a radially-inward projecting, longitudinally extending rail that extend in an axial direction along the second sub-length of the second portion of the inner surface of the wall of the ring gear body from the circumferentially extending rim to the second end of the wall of the ring gear body.
