LIMITED-SLIP DIFFERENTIAL, AND METHOD OF MANUFACTURING LIMITED-SLIP DIFFERENTIAL

摘要

PROBLEM TO BE SOLVED: To provide a limited-slip differential capable of securing high silence by optimizing a lubrication condition between sliding surfaces.;SOLUTION: A plurality of fine grooves 31 is formed in the teeth end surface of each planetary gear to thereby forming irregular recessed and projecting portions. The irregular recessed and projecting portions are composed of a plurality of first fine grooves 31a functioning as an oil groove and a plurality of second fine grooves 31b having depth shallower than that of each fine groove 31a.;COPYRIGHT: (C)2009,JPO&INPIT
