Abstract
A superfinishing method of a tapered roller bearing, including the steps of: rotating an outer ring of the tapered roller bearing about a center axis thereof; inserting a straight-shaped superfinishing stone from a front face of outer ring; and slidingly contacting a leading end face of the superfinishing stone with a taper-shaped raceway surface formed in an inner peripheral surface of the outer ring to thereby superfinish the raceway surface. The superfinishing stone is inclined outwardly of the front face of outer ring with respect to a vertical line of the raceway surface.

A superfinishing method of a tapered roller bearing, comprising the steps of:
- rotating an outer ring of the tapered roller bearing about a center axis thereof;
- inserting a straight-shaped superfinishing stone from a front face of outer ring;
- and
- slidingly contacting a leading end face of the superfinishing stone with a taper-shaped raceway surface formed in an inner peripheral surface of the outer ring to thereby superfinish the raceway surface,
- wherein the superfinishing stone is inclined outwardly of the front face of outer ring with respect to a vertical line of the raceway surface.
A superfinishing apparatus of a tapered roller bearing, comprising:
- a rotating device rotating an outer ring of the tapered roller bearing about a center axis thereof;
- a superfinishing stone holder holding a straight-shaped superfinishing stone;
- a driving device moving the superfinishing stone holder so that the superfinishing stone is inserted from a front face of outer ring and a leading end face of the superfinishing stone is slidingly contacted with a taper-shaped raceway surface formed in an inner peripheral surface of the outer ring to thereby superfinish the raceway surface,
- wherein the superfinishing stone holder holds the superfinishing stone in such a manner that the superfinishing stone is inclined outwardly of the front face of outer ring with respect to the vertical line of the raceway surface.
