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.
A one-piece sheet metal cage for an overrunning roller clutch wherein the cams 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.

A one-piece sheet metal cage for an overrunning roller clutch wherein the cams 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.
Claim 3
Dependent Claim
33 words
The cage of claim 1 wherein the higher end flange engaging the camming surfaces in a locking manner with an outer profile is provided with at least one opening for passing of lubricant.
Claim 4
Dependent Claim
42 words
The cage of claim 1 or 2 wherein securing tongues extending radially outward are provided on one end flange at various points about, the circumference bearing on the outer race with the camming surfaces to secure the cage in one axial direction.
Claim 5
Dependent Claim
27 words
The cage of claim 3 wherein the securing tongues are double offset so that the higher end flange is inside the outer race carrying the camming surfaces.
Claim 6
Dependent Claim
16 words
The cage of claim 1 wherein it is formed by bending round a flat metal strip.
