One way clutch

A one way clutch comprising an outer member integrally formed of a polymeric resin composition rotatable about a longitudinal axis and having formed therein a longitudinal cavity open at an end thereof, a sleeve of a relatively hard material located in said cavity and interlocked and rotatable with said outer member and having an inside peripheral face, an integrally formed cage member projecting into said cavity and including an outer base section and a plurality of circumferentially spaced inwardly directed longitudinal columns delineating retainer spaces, a rotatable inner drive member coaxial with said sleeve and outer drive member and having an outer peripheral faces delineating with said sleeve inside face a plurality of circumferentially spaced wedge spaces each containing a respective one of said retainer spaces, said cage and outer members having integrally formed therewith relatively radially resiliently movable complementary fastening means interlocking said members in assembled condition against relative longitudinal movement, a roller element disposed and circumferentially movable in each of said retainer spaces between wedging and release positions in respective wedge spaces to respectively drive couple and uncouple said drive members.

A one way clutch comprising an outer member integrally formed of a polymeric resin composition rotatable about a longitudinal axis and having formed therein a longitudinal cylindrical cavity open at an end thereof and having a peripheral groove formed therein at said end, a sleeve of a relatively hard material located in said cavity and interlocked and rotatable with said outer member and having on its inside peripheral face a plurality of circumferentially spaced similarly directed circumferentially radially inclined wedge surfaces, an integrally formed cage member projecting into said cavity and including an outer cylindrical base section telescoping said cavity and having a peripherally extending rib snap fit into engagement with said peripheral groove, and a plurality of circumferentially spaced inwardly directed longitudinal columns delineating retainer spaces registering with respective wedge surfaces, said cage and outer members having integrally formed therewith complementary fastening means interlocking said members in assembled condition against relative longitudinal movement, a roller element disposed and circumferentially movable in each of said retainer spaces and a shaft coaxially registering with said cage member, the opposite faces of said roller elements confronting the surface of said shaft and respective sleeve wedge surfaces.
