PURPOSE:To grind the outer peripheral surface of the outer ring of a rolling bearing with a shaft without dismantling the bearing or as it is by pushing the outer ring toward the shaft center by means of both a power transmission wheel and a pusher roll and then bringing a grinding wheel in contact with the counter periphery of the outer ring in said pushing direction. CONSTITUTION:A shaft 1 is fixed by center-supports. With suitable pressure-contact force, both a power transmission wheel 17 and a pusher roll 18 are pushed to the outer peripheral surface of an outer ring 3, during which time the ring 3 is ground as it is being turned. At this time, resultant force A, whose components consist of the pressure-contact force and the turning force of the transmission wheel 17, is produced at the top of the outer ring 3, while pressure contact force B of the pusher roll 18 acts at the front bottom, thereof and resultant force C consisting of pushing force and turning force of grinding wheel 19 is produced at the front face of the ring 3. As a result, the total resultant force D consisting of the force A, B, and C acts on the contact point between the grinding wheel 19 and the outer peripheral surface 3b of the outer ring 3 in nearly a fixed direction thereby making the radial clearance between a rolling body 4 and the track-surface 2a or 3a of the outer or inner ring, respectively, zero. As a result, this grinding work is equivalent to that based on the shaft center. Accordingly, the outer ring 3 can be ground as it is.
