PCT No. PCT/JP82/00018 Sec. 371 Date Sep. 14, 1982 Sec. 102(e) Date Sep. 14, 1982 PCT Filed Jan. 19, 1982 PCT Pub. No. WO83/02418 PCT Pub. Date Jul. 21, 1983.A method of manufacturing a bearing assembly for the wheels of automobiles, wherein an axle member B is ground by a first step wherein a raceway surface 5 and a cylindrical seat 6 are simultaneously ground, a second step wherein any deviation of the finished raceway diameter from its predetermined size is fed back to a gauge 23 for in-process control which controls the grinding operation on back-face rib surface 21 and shoulder 9, and a third step wherein the back-face rib surface 21 and shoulder 9 are ground simultaneously, while an inner annular member C is ground by a first step wherein a raceway surface 11 is ground, a second step wherein any deviation of the finished raceway diameter from its predetermined size is fed back to a gauge 29 for in-process control which controls the grinding operation on back-face rib surface 21 and front face 10, and a third step wherein the back-face rib surface 21 and front face 10 are ground simultaneously, and the inner annular member B is then fitted on the cylindrical seat 6 of the axle member B until the front face 10 abuts against the shoulder 9. The method eliminates the influences on the internal bearing clearance of the outer peripheral raceway surfaces of the axle member B and inner annular member C. |
