An Influence of Reciprocating Motion of Rotary Shaft on Sealing Characteristics of Oil Seals for Automotive Transmission

It is clear that excessive lip wear is one of the origin of oil seal leakage in the market. In this paper, follows are discussed; Oil seals used for the rear side of automotive mission gear case have excessive lip wear as typical failure mode, and the sealing characteristics of oil seals is influenced by reciprocating motion of rotational shaft with rough surface.
