Abstract
A gear box includes a housing, a shaft that is driven by the gear, the shaft including a recess, a bearing mounted between the shaft and the housing to support the shaft for rotation with respect to the housing about a rotation axis, and a ring assembly for axially securing the bearing to the shaft. The ring assembly surrounds the shaft and is seated in the recess. The recess has a retaining surface including a conical surface extending at an angle to the rotation axis, a curved surface, and a transition surface extending between the conical surface and the curved surface, the transition surface extending generally parallel to the rotation axis.
