Abstract

A one-piece sheet metal cage for an overrunning roller clutch wherein the cam rollers roll between a smooth inner races and an outer race provided with camming surfaces comprising a U-shaped sheet metal element provided in its longitudinal section with radial ends of different height, the higher end engaging the camming surfaces in a locking manner with a corresponding outer profile and the cage is provided with folding springs on radially directed segments on the cross-bars forming the cage pockets which cause the cam rollers to bear against an inner and outer retaining element of an adjacent cross-bar, each said cross-bar comprising a short segment extending in the circumferential direction at the bottom of the U-profile which forms the inner retaining elements at its axial ends adjoining the end flanges connecting the cross-bars and a flap between the inner retaining elements bent radially outward to which is secured a folding spring engaging an opening of the flap with an elastic projection, said flap being provided at its two axial ends with bent outer retaining lugs.
