Abstract
The present invention relates to a device for retaining a shaft within a differential case. A first groove is formed on the interior of an aperture formed through the differential case, which aperture is adapted to receive and retain one end of a shaft therein. The end of the aperture which faces outwardly of the differential case is provided with a chamfered shoulder thereabout. One or both of the sidewalls of the first groove are also chamfered outwardly from the groove. A second groove is formed in the exterior of the end of the shaft. The first and second grooves are adapted to be aligned when the end of the shaft is in a desired position relative to the differential case. A retaining ring is disposed in the first and second grooves in interfering relationship between the shaft and the differential case so as to prevent axial movement of the shaft relative to the differential case. The depths of the two grooves and the angles of inclination of the sidewalls of the first groove formed in the differential case can be varied so as to permit or prevent destruction of the retaining ring when the shaft is removed therefrom, and further to vary the amount of force required to accomplish such disassembly.
