Patent ID: 8151434

Claim:
A method of producing a rolling bearing device for a wheel, wherein the rolling bearing device includes an outer ring, an inner ring, and a plurality of rolling elements, wherein the outer ring or the inner ring is provided with a brake disk mounting flange, wherein the brake disk mounting flange includes a brake disk mounting surface, and wherein the brake disk mounting surface is formed to accept a brake disk directly or indirectly mounted thereto, wherein the method of forming the rolling bearing device comprises: providing the rolling bearing device for the wheel in a state where the outer ring, the inner ring and the plurality of rolling elements are assembled and an annular recess is formed on the brake disk mounting surface; providing an annular grinding wheel, the annular grinding wheel including a width smaller than a width of the recess in a radial direction, the annular grinding wheel being inclined with respect to the brake disk mounting surface such that a distance between the grinding surface and the brake disk mounting surface increases in a direction from the annular recess of the brake disk mounting surface toward an outer edge of the brake disk mounting surface; rotating the outer ring or the inner ring around a center axis of the inner ring or a center axis of the outer ring; grinding the brake disk mounting surface, wherein the brake disk mounting surface is ground by bringing the brake disk mounting surface into contact with the annular grinding wheel, wherein during the grinding of the brake disk mounting surface a first portion of the annular grinding wheel overlaps the recess over an entire region of the annular grinding wheel in the radial direction from an outer periphery to an inner periphery of the annular grinding wheel, and wherein a second portion of the annular grinding wheel does not overlap the annular recess.
