ROLLER-TYPE ONE-WAY CLUTCH

摘要

In a roller type one-way clutch comprising: an outer race; an inner race that is apart from the outer race on an inner diameter side in a radial direction and concentrically arranged to allow its relative rotation; a plurality of rollers that are arranged between the outer race and the inner race and transmit a torque between the outer race and the inner race; and a plurality of block bearings that are arranged between the rollers and between the outer race and the inner race, the roller type one-way clutch is characterized in that a curvature in a circumferential direction of a bearing surface of the block bearing facing an outer peripheral surface of the inner race is higher than a curvature in the circumferential direction of the outer peripheral surface of the inner race.
