ABSTRACT:
A gear mesh configuration which eliminates independent means for retaining a gear in rotational contact with another. As illustrated by the mesh formed between the cooperating teeth of a side gear and pinion mate in a vehicle differential assembly, the mesh is formed axially and radially inward of the side gear as compared to conventional gear combinations. In this manner, an area is formed in the side gear which is outward of the teeth and which extends around the rear portion of a pinion to retain it in its desired position upon the supporting shaft. Because the gear mesh is now substantially sealed, this configuration also serves to create a limited-slip effect.
