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 1):
A roller bearing defining a bearing axis and a radial plane oriented parallel with the bearing axis, the roller bearing comprising:\n an inner ring including an inner raceway and an inner flange extending from the inner raceway, the inner flange including an inner guide surface; and a plurality of rollers in rolling engagement with the inner raceway about the bearing axis, each roller including a first end surface in engagement with the inner guide surface of the inner flange as the plurality of rollers move relative to the inner ring; wherein the first end surfaces of each roller define a curvature such that a ratio of a first principal effective curvature radius in a plane perpendicular to the radial plane and a second principal effective curvature radius in the radial plane is no less than 3.0; wherein the first principal effective curvature radius at a contact area between the inner flange and the first end surfaces of the plurality of rollers is defined as: R x = ( D rol - 2 \ue89e h cnt ) \ue89e ( D inr + 2 \ue89e h cnt ) 2 \ue89e ( D rol + D inr ) \ue89e sin \ue89e \ue89e \u03b2 and wherein D rol  is the diameter of the plurality of rollers, h cnt  is the height of contact between the plurality of rollers and the inner guide surface relative to the inner raceway, D inr  is the diameter of the inner raceway, and \u03b2 is the contact angle between a tangent line through a contact point between the first end surfaces of the plurality of rollers and the inner guide surface and a line perpendicular to the bearing axis; and wherein the second principal effective curvature radius is defined as: R y = R rib \ue89e \ue89e 2 \u00b7 R rol \ue89e \ue89e 2 R rib \ue89e \ue89e 2 + R rol \ue89e \ue89e 2 and wherein R rib2  is a curvature radius of the inner guide surface within the radial plane, and R rol2  is a curvature radius of the first end surfaces of the plurality of rollers near the contact point within the radial plane.
