Cam follower for high axial load applications
First Claim
1. A roller assembly for a cam follower or a yoke roller, the roller assembly comprising:
- an outer ring having an interior area, the interior area being defined by an inner surface extending between a first axial end and a second axial end of the outer ring, the inner surface having a radially inward facing bearing surface extending between a first radially inwardly extending flange and a second radially inwardly extending flange, the first radially inwardly extending flange has a first axially inward facing abutment surface and the second radially inwardly extending flange has a second axially inward facing abutment surface;
a one piece shaft extending into the interior area, the shaft extending continuously between a third axial end and a fourth axial end of the shaft, the shaft having a head flange extending radially outward from the shaft proximate the third axial end, the head flange having a third axially inward facing abutment surface, and the shaft having an exterior bearing surface, extending between the third axially inward facing abutment surface and a circumferential retainer receiving surface, the circumferential retainer receiving surface being located between the third axial end and the fourth axial end;
a first row of a plurality of first rollers positioned in the interior area between and in rolling engagement with the exterior bearing surface and the radially inward facing bearing surface;
a second row of a plurality of second rollers positioned in the interior area between and in rolling engagement with the exterior bearing surface and the radially inward facing bearing surface;
a spacer ring disposed around and engaging the exterior bearing surface, the spacer ring being positioned between the first row of the plurality of first rollers and the second row of the plurality of second rollers;
a retainer ring secured to the retainer receiving surface, the retainer ring having a fourth axially inward facing abutment surface;
the outer ring being axially retained on the first row of the plurality of first rollers and the second row of the plurality of second rollers by and between the first axially inward facing abutment surface and the second axially inward facing abutment surface; and
the first row of the plurality of first rollers, the spacer and the second row of the plurality of second rollers being axially retained on the shaft by and between the third axially inward facing abutment surface and the fourth axially inward facing abutment surface such that the roller assembly withstands an axial load of up to 100 percent of an applied radial load.

Abstract
A roller assembly includes an outer ring having an interior area defined by an inner surface extending between a first and second axial end thereof. The inner surface has a bearing surface. A flanged headed shaft having an exterior bearing surface extends into the interior area. The shaft has a circumferential retainer receiving surface thereon. Two rows of rollers are positioned in the interior area with a spacer ring therebetween. A retainer ring is secured to the retainer receiving surface. The two rows of rollers and the spacer are axially retained on the shaft by and between the flanged head and the retaining ring so that the roller assembly withstands an axial load of up to 100 percent of an applied radial load.
