Abstract
A full type one-way clutch includes rollers arranged in a full type state between an outer ring having inclined cam surfaces on the inner peripheral surface thereof and a rotary shaft. A spring biases the rollers in such a direction as to engage the cam surfaces, and the spring is arranged in a groove formed in the inner peripheral surface of the outer ring. By keeping all the rollers in abutment with one another, it is possible to reliably and instantly transmit the biasing force of the spring to all the rollers without reducing the torque-transmitting ability while improving the responsiveness of the clutch.
Claims22
A one-way clutch comprising:
- an outer member having an inner peripheral surface;
- an inner member having an outer peripheral surface, a first one of said inner peripheral surface of said outer member and said outer peripheral surface of said inner member having a plurality of inclined cam surfaces formed thereon, and a second one of said inner peripheral surface of said outer member and said outer peripheral surface of said inner member having a cylindrical surface;
- a plurality of rollers arranged between said outer member and said inner member so as to oppose said cam surfaces and so that adjacent rollers abut each other;
- and
- a resilient member engaging one of said inner peripheral surface of said outer member and said outer peripheral surface of said inner member, said resilient member being arranged to bias said rollers in a circumferential direction with respect to said inner member and said outer member so that said rollers engage said cam surfaces.
