Method for manufacturing a torque transmission mechanism

摘要

This method is for manufacturing a torque transmission mechanism (A) between a starter motor and a crankshaft (4) of an internal combustion engine, comprising a one-way clutch (8) including an outer ring (84) fast in rotation with the crankshaft (4) via a front plate (10). This method comprises the following steps: a) forging the outer ring (84) out of carburizing steel, b) carburizing the outer ring (84), c) tempering the outer ring (84), d) grinding an inner surface (842) of the outer ring (84), e) manufacturing the front plate (10) out of standard low equivalent carbon content steel, f) assembling the front plate (10) and the outer ring (84).
