Abstract
An axial bearing includes a shaft washer and a housing washer. An extension of the shaft interface is incorporated into the shaft washer and an extension of the housing interface is incorporated into the housing washer. As a result, the forces on the bearing are distributed more reliably to the shaft and housing, and the stresses internal to the bearing are more reliably and evenly distributed. This results in improved bearing performance and improved operating life. The bearing washer is more reliably located. The assembly is optimized in that mating components are potentially eliminated, and component dimensions are potentially reduced.
Claims12
An axial bearing assembly comprising:
- a housing washer having a first extension protruding in a first axial direction and a radial locating feature protruding in a second axial direction opposite the first axial direction;
- a shaft washer having a second extension protruding in the first axial direction;
- and
- a plurality of rollers separating the housing washer from the shaft washer and radially inside the first extension.
An axial bearing comprising:
- a shaft washer and a housing washer separated by a plurality of rollers;
- wherein the shaft washer has a body in contact with the rollers and a first extension protruding away from the rollers to contact a shaft abutment;
- and
- wherein the housing washer has a second extension protruding radially outside the rollers beyond the body of the shaft washer.
