Rolling-element bearing
First Claim
1. A rolling-element bearing comprising:
- an inner race;
an outer race; and
an array of rolling elements arranged within a bearing cage situated between inner race and the outer race, an inner surface of the bearing cage being piloted on the inner race for limiting eccentric movement of the bearing cage within the bearing, and further having a reservoir formed between a pair of circumferential weirs on the bearing cage, an outer surface of the inner race comprising a raised land portion for contacting oil in the reservoir thereby to control a relative speed of the bearing cage and the inner race, whereina radial depth of each of the weirs is greater than a maximum radial clearance between the land portion and the bearing cage for maintaining a controlling contact between the land portion and the oil during the eccentric movement of the bearing cage,one or more of the weirs are detachable for permitting axial disassembly of the bearing cage from the inner race, andone or more of the detachable weirs are in a form of a resilient ring element that engages the inner surface of the bearing cage in a compression fit.

Abstract
A rolling-element bearing 1 comprising an inner race 3, an outer race 2 and an array of rolling elements 4 arranged within a bearing cage 5 situated between the two races 2, 3, the inner surface of the bearing cage 5 being piloted on the inner race 3 for limiting eccentric movement of the cage 5 within the bearing 1 and further having a reservoir 9 formed between a pair of circumferential weirs 6a, 7b on the cage 5, the outer surface of the inner race 3 comprising a raised land portion 3d for contacting oil 9a in the reservoir 9 thereby to control the relative speed of the cage 5 and the inner race 3, wherein the radial depth of each weir 6b, 7b is greater than the maximum radial clearance between the land portion 3d and the cage 5 for maintaining said controlling contact between the land portion 3d and the oil 9a during said eccentric movement of the cage 5.
