Bearing with bearing cage
First Claim
Patent Images
1. A bearing comprising:
- a first race;
a second race spaced from the first race;
a cage located in the space between said races and normally spaced from both the first race and the second race, said cage having a plurality of circumferentially spaced rolling member pockets;
rolling members located in said pockets, said cage being rotated by the rolling members in response to relative rotation of the first race with respect to the second race;
fluid in the space between said two races;
said cage having a plurality of generally wedged-shaped recesses, each recess having at least one opening at its deep end, the opening at said deep end being located so that during cage rotation in a particular direction, fluid is scooped into the recess and wedged at the shallow end of its recess between the cage wall and a cage piloting surface so that during rotation of the cage, any force tending to move the cage from said normally spaced position into contact with said cage piloting surface is automatically opposed by a hydrodynamic force acting to keep the cage out of such contact.

Abstract
An annular cage for the rollers of a bearing is located in the annular space between two bearing races and is normally spaced from both races when concentric. The cage is so constructed that, when unbalanced forces on the cage during rotation in the bearing tend to move the cage from its concentric position into contact with a piloting surface, hydrodynamic forces are developed which act to keep the cage out of contact with that surface.
