ABSTRACT:
This rolling bearing includes an inner race, an outer race, rolling members--either balls or rollers--disposed between these races and rotatably supporting them relative to one another, and generally cylindrical retainers disposed between these rolling members, each rolling on its two adjacent rolling members and keeping them apart. Each retainer has an axially central portion rollingly contacting with these two adjacent rolling members, a pair of circumferential grooves each near one of its ends, and a pair of disk shaped end portions each near one of its ends. These retainers are positioned by their disk shaped end portions rolling on the one radial sides of support rails defined on a pair of covers mounted each at one axial end of one race, and by their grooves being engaged over the other radial sides of free rings each at one bearing axial end. The retainers either may roll on the radially outer sides of the rails and on the radially inner sides of the rings, or vice versa. The covers may be mounted to the inner or outer race. Radial play may be available for the retainers between the rails and rings. The center line of each retainer and the locuses of symmetry of the two adjacent rolling members may be coplanar. The thickness of the rings may be greater remote from where they contact the grooves of the retainers than proximate thereto. A device may be provided for impelling lubricant through the space between the races.
