Abstract:
A raceway surface ( 3 a ) of an outer ring ( 3 ) of a tapered roller bearing ( 1 ) includes a composite crowning surface. The composite crowning surface includes a center curve ( 3 a 1 ), which is formed at a center portion in a generating-line direction, and end portion curves ( 3 a 2  and  3 a 3 ), which are formed on both sides of the center curve ( 3 a 1 ) in the generating-line direction. The raceway surface ( 3 a ) of the outer ring ( 3 ) is entirely subjected to superfinishing. Each of a ratio (R 2 /R 1 ) of a curvature radius (R 2 ) of the end portion curve ( 3 a 2 ) to a curvature radius (R 1 ) of the center curve ( 3 a 1 ) and a ratio (R 3 /R 1 ) of a curvature radius (R 3 ) of the end portion curve ( 3 a 3 ) to the curvature radius (R 1 ) is set to 0.02 or more. Each of drop amounts of the end portion curves ( 3 a 2  and  3 a 3 ) is set to 0.07 mm or less.

Claim (Index 9):
The tapered roller bearing according to  claim 7 ,\n wherein the inner ring comprises a small-flange portion which is formed on a small-diameter side of the raceway surface, and wherein, under the state in which the inner ring, the outer ring, and the plurality of tapered rollers are arranged at the normal positions, a distance between a small-diameter-side end surface of the each of the plurality of tapered rollers and the small-flange portion of the inner ring is set to 0.4 mm or less.
