Abstract

The invention concerns a bearing comprising concentric, annular, inner and outer races between which there is concentrically disposed an annular cage having pockets within which are retained rolling elements which are in rolling engagement with the inner and outer races, the radially inner surface of the cage being provided both with at least one journal portion which engages the inner race and with lubricant reservoir means which communicate with the said pockets for the supply of lubricant thereto.

Claims

1. A bearing comprising:

concentric annular inner and outer races;

an annular cage disposed concentrically between said inner and outer races, said annular cage having angularly spaced-apart pockets;

rolling elements retained in said pockets and in rolling engagement with said inner and outer races;

said cage having a radially inner surface with at least one journal portion engaging said inner race;

lubricant reservoir means provided on said cage and which communicates with said pockets for the supply of lubricant thereto, said lubricant reservoir means comprising a plurality of angularly spaced-apart recesses in said inner surface of said cage, one of said recesses being provided between eacH two adjacent pockets, each of said recesses being separated from each of its adjacent pockets by axially extending lands, at least one of said lands for each recess being provided with at least one lubricant passage through which lubricant may pass from the recess to the respective pocket.

2. A bearing as claimed in claim 1 in which only the trailing land, with respect to the direction of rotation of said cage, is provided with said at least one lubricant passage, each of the leading lands acting as lubricant barriers.

3. A bearing as claimed in claim 1 in which said rolling elements are balls.

4. A bearing as claimed in claim 1 in which said rolling elements are rollers.
