Abstract
A bearing with shallow grooves on the surface of the rolling element. In addition, pockets of lubricant are carried in its own internal structure via a network of through-holes crossing at its center which release lubricant to the grooves and surface of the rolling element upon the rotation of the bearing assembly.
Claims17
A bearing rolling element, comprising:
- a solid, spherical bearing ball having a circumferential equator, an external surface, a solid interior, an interior center, and two poles on the external surface, one designated as the north pole and the other designated as the south pole, said bearing ball having a plurality of interconnecting shallow grooves formed on the bearing ball external surface, said bearing ball having a plurality of generally straight, elongated apertures having a circular cross section formed along a bearing ball radial axis through said interior center, each said aperture having two ends, each said end opening into at least one of said grooves.
A bearing rolling element, comprising:
- a solid, cylindrical bearing rolling element having a first side from which a cylindrical side wall extends horizontally to a second side, opposite and parallel to said first side, said sides defining a longitudinal axis of said cylindrical bearing, said longitudinal axis being generally perpendicular to the bearing sides, said cylindrical bearing having an external surface, a solid interior, a plurality of equally spaced, parallel, longitudinal, shallow grooves formed in said external surface, each said groove extending from the first side wall to the second side wall, each said longitudinal groove being parallel to the longitudinal axis of the cylindrical bearing, said cylindrical bearing having a generally straight, elongated aperture formed through the cylindrical bearing center along a central, longitudinal axis of the cylindrical bearing, said cylindrical bearing having a plurality of sets of a plurality of apertures interconnecting each longitudinal surface groove with the central, elongated aperture, said sets of apertures being equally spaced along the longitudinal axis of said cylindrical bearing.
