One-way clutch

Abstract

The purpose of the present invention is to provide a one-way clutch that is simple and easy to manufacture, can be made compact in the axial direction, is compact and lightweight, is resistant to breakage, and can prevent abrasion of an inner peripheral engagement surface and an outer peripheral engagement surface of a cam during high-speed idling. This one-way clutch is provided with an inner ring (110) and an outer ring (150) that are disposed coaxially so as to be able to rotate relatively to one another, a plurality of cams (140) that are disposed between the inner ring (110) and the outerring (150) in the circumferential direction, and side plates (120), (130) that are disposed on at least the inner ring (110) or the outer ring (150) and are located on both sides of the cams (140) inthe axial direction. Each of the plurality of cams (140) receives a prescribed centrifugal force when the inner ring (110) and the outer ring (150) both rotate in the same direction and turns in thedirection of engagement with the inner ring (110) and the outer ring (150).

Description

technical field [0001] The present invention relates to a one-way clutch provided with a plurality of cams between an inner ring and an outer ring and configured so that when the inner ring is rotated in one direction or the outer ring is rotated in the other direction , the engaging surface on the inner peripheral side and the engaging surface on the outer peripheral side of the cam are respectively frictionally engaged with the outer peripheral engaging surface of the inner ring and the inner peripheral engaging surface of the outer ring. When the inner ring is rotated in the other direction or the outer When the ring rotates in one direction, the inner ring or the outer ring performs idle rotation. Background technique [0002] Conventionally, one-way clutches used when the inner and outer rings are idling at high speeds have used cages that hold cams. By holding the cam with a retainer fixed to the inner or outer ring on the high-speed idling side, the cam rotates in th...

Problems solved by technology

However, when the inner and outer rings are idling at high speeds, the influence of abrasion of the inner and outer engagement surfaces of the cam becomes greater, so this structure is not suitable for inner and outer rings. One-way clutch used when idling at high speed

[0011] In addition, the one-way clutch has a problem that it is difficult to reduce the size of the one-way clutch in the axial direction due to the urging means that urges the plurality of cams in the inner diameter direction or the outer diameter direction.

In addition, there is also a problem that, when assembling the clutch, a large number of parts are required, resulting in a large workload.
