Abstract
Abstract A roller bearing assembly comprising inner and outer ring members spaced apart to define an annular space for a plurality of rollers, each of the ring members having a radially directed flange confronting the axial end faces of the rollers, said roller end faces and flange surface confronting said roller end faces being of a predetermined configuration whereby the rollers assume an essentially stable equilibrium condition tilted at a predetermined angle relative to the bearing axis during operation of the bearing under axial load and a cage having a plurality of pockets for the rollers defined in part by axially oriented bars of a configuration so that the rollers can be tilted said predetermined angle and essentially limited only by the contact between said roller end faces of the surface of said flanges confronting and engaging said roller end faces.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
161 words
A roller bearing assembly comprising inner and outer ring members spaced apart to define an annular space for a plurality of rollers, each of the ring members having a radially directed flange having a surface confronting the axial end faces of the rollers, said roller end faces and flange surfaces confronting said roller end faces being of a predetermined configuration whereby the rollers assume an essentially stable equilibrium condition tilted at a predetermined angle relative to the bearing axis during operation of the bearing under axial load and a cage having a plurality of pockets for the rollers defined in part by axially oriented bars of a configuration so that the contact between rollers and cage is in a zone adjacent the middle of the cage bars and the rollers can be tilted said predetermined angle and essentially limited only by the contact between said roller end faces and the surface of said flanges confronting and engaging said roller end faces.
Claim 2
Dependent Claim
161 words
A roller bearing assembly comprising inner and outer ring members spaced apart to define an annular space for a plurality of rollers, each of the ring members having a radially directed flange having a surface confronting the axial end faces of the rollers, said roller end faces and flange surfaces confronting said roller end faces being of a predetermined configuration whereby the rollers assume an essentially stable equilibrium condition tilted at a predetermined angle relative to the bearing axis during operation of the bearing under axial load and a cage having a plurality of pockets for the rollers defined in part by axially oriented bars of a configuration so that the contact between rollers and cage is in a zone adjacent the middle of the cage bars and the rollers can be tilted said predetermined angle and essentially limited only by the contact between said roller end faces and the surface of said flanges confronting and engaging said roller end faces.
Claim 3
Dependent Claim
28 words
A roller bearing assembly as claimed in claim 1, characterized by that the cage pockets are relatively narrower at their middle positions and are widening towards the ends.
Claim 4
Dependent Claim
37 words
A roller bearing assembly as claimed in claim 2 wherein the side edges of the pocket confronting the rollers taper outwardly from the center portion of the bar at an angle of between about 20'' and 1*.
Claim 5
Dependent Claim
19 words
A roller bearing assembly as claimed in claim 1 wherein the roller end faces are of a spherical shape.
