Abstract

A gear retention assembly for retaining a gear that has a plurality of gear outer splines includes a gear housing and a retaining ring. The gear housing has a first end, a second end, and a plurality of inner splines each including a ramp portion. The second end of the gear housing includes an annular continuous rolled lip, where the continuous rolled lip and the ramp portions of the plurality of inner splines define a groove. The plurality of inner splines engage with the gear outer splines of the gear to transmit torque between the gear and the gear housing. The retaining ring is disposed in the groove and axially retains the gear. The rolled lip axially retains the retaining ring.
