Abstract
Abstract A roller bearing having inner and outer rings each having races of a curved shape axially of the bearing. A plurality of rollers are arranged between the rings, the rollers having a surface conforming to curvature of the races and axes sloping toward the axis of the bearing. At least one of the rings having a separate retaining rim.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
111 words
A roller bearing comprising an inner and outer ring each having an axially curved race surface, a plurality of rollers arranged between said rings in a single row each with their respective axes inclined in the same direction toward the central axis of said bearing, said rollers having curved outer surfaces conforming to the curve of said races, a shoulder integrally formed at the axial end of one of said rings to maintain said rollers against axial movement in one direction and at least the other one of said rings having a separate retaining rim at the axially opposite end for maintaining the rollers against axial movement in the other direction.
Claim 2
Dependent Claim
111 words
A roller bearing comprising an inner and outer ring each having an axially curved race surface, a plurality of rollers arranged between said rings in a single row each with their respective axes inclined in the same direction toward the central axis of said bearing, said rollers having curved outer surfaces conforming to the curve of said races, a shoulder integrally formed at the axial end of one of said rings to maintain said rollers against axial movement in one direction and at least the other one of said rings having a separate retaining rim at the axially opposite end for maintaining the rollers against axial movement in the other direction.
Claim 3
Dependent Claim
33 words
The bearing according to claim 1 wherein said races are concave and said roller surface is convex, and the high point of said curve lies along the radial transverse axis of the bearing.
Claim 4
Dependent Claim
28 words
The bearing according to claim 1 wherein curve of said race and said rollers is unsymmetrical and has a greater diameter at one end than at the other.
Claim 5
Dependent Claim
88 words
A roller bearing comprising an inner and an outer ring each having an asymmetrical axially curved race surface having a greater diameter at one end than at the other, a plurality of rollers arranged between said rings with their respective axes inclined toward the central axis of said bearing, said rollers having curved outer surfaces conforming to the curve of said races, at least one of said rings having a separate retaining rim, said separate retaining rim being located on the outer ring adjacent the larger diameter end.
Claim 6
Dependent Claim
88 words
A roller bearing comprising an inner and an outer ring each having an asymmetrical axially curved race surface having a greater diameter at one end than at the other, a plurality of rollers arranged between said rings with their respective axes inclined toward the central axis of said bearing, said rollers having curved outer surfaces conforming to the curve of said races, at least one of said rings having a separate retaining rim, said separate retaining rim being located on the outer ring adjacent the larger diameter end.
Claim 7
Dependent Claim
25 words
The bearing according to claim 3 wherein the separate retaining rim is located on the inner ring adjacent the smaller diameter end of the raceway.
Claim 8
Dependent Claim
37 words
The bearing according to claim 1, wherein said separate rim is secured to said retAining ring by an annular clip having lateral flanges adapted to seat within mating grooves formed in the rim and associated ring, respectively.
Claim 9
Dependent Claim
33 words
The bearing according to claim 1 wherein the sides of said rollers are formed with a bow shape and the surfaces of said ring rims are formed with a corresponding curved race surface.
