Abstract
A one-way clutch of the invention includes an inner race supported for rotation on a power transmission shaft, an outer race concentrically surrounding the inner race, and torque transmitting members interposed between the inner race and the outer race and capable of transmitting torque in one direction of the inner race to the outer race. The outer race is integrally provided with an extending portion that extends inwardly in a radius direction thereof. The extending portion is capable of being engaged with the power transmission shaft.
Claims12
A one-way clutch comprising:
- an inner race supported for rotation on a power transmission shaft;
- an outer race concentrically surrounding the inner race;
- and
- torque transmitting members interposed between the inner race and the outer race and capable of transmitting torque in one direction of the inner race to the outer race;
- wherein the outer race is integrally provided with an extending portion that extends inwardly in a radius direction thereof, and
- the extending portion is capable of being engaged with the power transmission shaft, the outer race and the extending portion being formed as a single member by forging, wherein
- the outer race including the extending portion is subjected to a carburizing process, and then the extending portion is treated by a tempering process.
