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.

Bearing retention system

A gear box includes a housing, an actuator coupled to the housing, and a bearing assembly pivotably coupled to the actuator. The bearing assembly including an outer raceway, a cylindrical housing positioned within the outer raceway, and an annular bearing positioned between the outer raceway and the housing. The cylindrical housing has a first end and a second end opposite the first end. A sensor is coupled to the first end of the cylindrical housing and configured to monitor an operating condition of the annular bearing. A linkage couples the actuator to the second end of the cylindrical housing and an output shaft is rotatably coupled to the bearing assembly.
