ABSTRACT:
A helical gear differential includes lubrication passages for circulating lubricating oil to the helical pinion counter bores and the side gear counter bores, thereby to increase the operating life of, and to reduce the operating noise level of, the differential. Openings contained in one of the housing and cover sections introduces lubricating oil into the ends of the associated pinion bores to lubricate the ends of the adjacent pinions, and the oil flows through the housing openings to lubricate the remote ends of the pinions. The adjacent ends of the other pinions are lubricated via second housing openings contained in the walls of housing relieved portions. An improved retaining means including a plate and a split snap ring serve to retain the cross pin spacer member within a transverse bore contained in the housing body section.
