STRUCTURE OF ONE-WAY BEARING

Abstract: a one-way bearing is arranged between an input member and an output member and includes a plastic mounting base, a plurality of rollers, and a metallic transmission base. the plastic mounting base is molded to form a plurality of equidistant and radially-penetrating mounting recesses, and the rollers are respectively received in the mounting recesses. a circumferential surface of the metallic transmission base that corresponds to the plastic mounting base is formed with a plurality of transmission slopes respectively corresponding to the mounting recesses, so that the rollers arranged in the plastic mounting base may selectively clamp the metallic transmission base by means of the transmission slope to induce an effect of one-way driving. in this way, the molded plastic mounting base may help reduce the weight of the one-way bearing without affecting the strength for power transmission, achieving advantages of light weight, cost reduction, and easy machinability.
