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 6):
A method for design of the roller bearing of  claim 1 , including determining the ratio of the first and second principal effective curvature radii at the contact area between the first end surfaces and the corresponding inner guide surface by minimizing a friction moment between the first end surfaces and the corresponding inner flange.
