Abstract
Abstract An antifriction bearing comprising an inner and outer ring between which a plurality of bearing elements are located. The elements are arranged in two parallel rows spaced from each other and a cage holding at least one row is interposed therebetween. The cage is provided with surfaces which engage the antifriction elements and which cause them to clamp against the races and stop from rotating in one direction. At least one of the cage, inner race and outer race members is divided in the radial direction and a resilient element is interposed between the divided portions to bias one portion with respect to the other.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
A bearing comprising inner and outer race rings, a plurality of antrifriction bearing elements positioned therebetween and arranged in two annular rows axially spaced from each other, a cage arranged between said rows provided with means for holding the bearing elements in at least one row and having clamping surfaces thereon adapted to engage said bearing elements for selective clamping of said elements between same and said inner and outer race rings, resilient means being provided in association with at least one of said cage and inner and outer race rings for resiliently biasing said bearing elements against said clamping surfaces to thereby stop rotation of said bearing elements in a selected direction.
Claim 2
Dependent Claim
113 words
A bearing comprising inner and outer race rings, a plurality of antrifriction bearing elements positioned therebetween and arranged in two annular rows axially spaced from each other, a cage arranged between said rows provided with means for holding the bearing elements in at least one row and having clamping surfaces thereon adapted to engage said bearing elements for selective clamping of said elements between same and said inner and outer race rings, resilient means being provided in association with at least one of said cage and inner and outer race rings for resiliently biasing said bearing elements against said clamping surfaces to thereby stop rotation of said bearing elements in a selected direction.
Claim 3
Dependent Claim
28 words
The bearing according to claim 1 wherein the bearing elements are balls and the rings are formed with inclined race surfaces for each of the rows of balls.
Claim 4
Dependent Claim
48 words
The bearing according to claim 2 wherein the resilient bias causes the balls to be engaged in a triangular point array, one point being on the clamping surface, one point on the race of the outer ring and one point being on the race of the inner ring.
Claim 5
Dependent Claim
67 words
A bearing according to claim 1, wherein the clamping surfaces of said cage are adapted to engage said bearing elements in the axial direction in One direction of bearing rotation, at least one of said cage, inner and outer race ring being axially divided, said resilient means being arranged between the divided portions for resiliently biasing said portions in an axial direction with respect to one another.
Claim 6
Dependent Claim
17 words
The bearing according to claim 4 wherein said means for resiliently biasing said portions comprises a spring.
Claim 7
Dependent Claim
22 words
The bearing according to claim 4 wherein said means for resiliently biasing said portions comprises a sealed pressure chamber and piston arrangement.
Claim 8
Dependent Claim
18 words
The bearing according to claim 4 wherein said means for resiliently biasing said portions comprises a resilient block.
Claim 9
Dependent Claim
36 words
The bearing according to claim 4 wherein at least one of said race rings is divided and including an actuating device for axially shifting the portions of the divided race rings in relative to one another.
Claim 10
Dependent Claim
45 words
The bearing according to claim 1 wherein said means for resiliently biasing said bearing elements comprises an annular member secured to the surface of said cage, said annular member having extending tongues resiliently engaging the antifriction elements and biasing the same against the clamping surface.
