Roller-type one-way clutch

摘要

Provided is a roller type one-way clutch that can prevent rollers from coming off at the time of conveyance and assembling of an outer race without increasing a cost and a weight. The roller type one-way clutch includes: an outer race having pockets that have a cam surface formed on an inner surface thereof; an inner race that is apart on an inner diameter side in a radial direction from the outer race, concentrically arranged to allow its relative rotation, and has an annular outer peripheral raceway surface; a plurality of rollers each of which is arranged in each pocket, engaged with the cam surface, and transmits torque between the outer race and the inner race; and springs each of which is arranged in each pocket and energizes each roller by one end portion thereof in an engaging direction with respect to the cam surface, the other end portion of each spring is fixed to the outer race, and a support portion that supports each roller in a radial direction is provided at the other end portion.

1. A roller type one-way clutch comprising:
an outer race having pockets that have a cam surface formed on an inner surface thereof; an inner race that is concentric with the outer race and that is spaced from the outer race in a radial direction of the clutch to allow relative rotation of the races, and that has an annular outer peripheral raceway surface; a plurality of rollers each of which is arranged in a corresponding pocket, engaged with the cam surface, and transmits torque between the outer race and the inner race; and springs each of which is arranged in a corresponding pocket and energizes a corresponding roller by one end portion thereof in an engaging direction with respect to the cam surface, wherein the other end portion of each spring is fixed to the outer race, and has, as an integral part of the other end portion of the spring, a support portion that supports an adjacent roller in said radial direction and that is constructed so that a single support portion for each roller is sufficient to prevent the roller from coming off of its pocket in the radial direction.
