Abstract:
A roller bearing ( 10 ) defines a bearing axis ( 34 ) and a radial plane ( 52 ) oriented parallel with the bearing axis. The roller bearing ( 10 ) includes an inner ring ( 42 ) having an inner raceway ( 44 ) and an inner flange ( 46 ) extending from the inner raceway. The inner flange ( 46 ) includes an inner guide surface ( 48 ). The roller bearing ( 10 ) also includes a plurality of rollers ( 22 ) in rolling engagement with the inner raceway ( 44 ) about the bearing axis ( 34 ). Each roller ( 22 ) includes a first end surface ( 24 a ) in engagement with the inner guide surface ( 48 ) of the inner flange ( 46 ) as the plurality of rollers ( 22 ) move relative to the inner ring ( 42 ). The first end surfaces ( 24 a ) of each roller ( 22 ) define a curvature such that a ratio of a first principal effective curvature (Rx) radius in a plane perpendicular to the radial plane ( 52 ) and a second principal curvature radius (Ry) in the radial plane ( 52 ) is no less than 3.0.

Claim (Index 7):
A method for design of the roller bearing of  claim 5 , including determining the ratio of the first and second principal effective curvature radii at the contact area between the first and second end surfaces and the corresponding inner and outer guide surfaces by minimizing a friction moment between the first and second end surfaces and the corresponding inner and outer flanges.
