摘要： An outer ring of an axle bearing is heat-treated and a through hole can be formed quickly and reliably. The outer ring has raceways on its inner periphery along which rolling elements roll. A through hole for mounting an antilock brake sensor is formed in the outer ring to extend from its outer periphery to the inner periphery. A plug is inserted into the hole thus formed. After hardening the raceways, the plug is pulled out of the hole. Since the hole is formed before hardening the raceways, it can be formed easily by drilling with an ordinary carbon steel tool. Since the raceways are hardened after inserting the rod-shaped metal plug into the hole 9, the heat produced during hardening will disperse through the plug. It is thus possible to prevent shoulder portions of the raceways from melting due to overheating.
摘要翻译：对轴承的外圈进行热处理，能够快速，可靠地形成通孔。外圈在其内周上具有滚道滚动的滚道。在外圈中形成有用于安装防抱死制动器传感器的通孔，以从其外周延伸到内周。将插头插入如此形成的孔中。将导轨硬化后，将插头从孔中拉出。由于在硬化滚道之前形成孔，所以可以用普通的碳钢工具进行钻孔来形成。由于在将棒状金属塞插入孔9之后使滚道硬化，所以在硬化过程中产生的热将分散通过塞子。因此可以防止滚道的肩部由于过热而熔化。

摘要： A bearing apparatus for a driving wheel of vehicle where the weight and size of the apparatus can be reduced and the durability can be improved with adopting plastic deformed connection between essential parts forming the apparatus. The bearing apparatus for a driving wheel of vehicle has a hub wheel, a constant velocity universal joint, and a double row rolling bearing which are assembled as a unit. One of the inner raceway surfaces is formed on the outer circumferential surface of the hub wheel. The other of the inner raceway surfaces is formed on the outer circumferential surface of the outer joint member. The hub wheel and the outer joint member are fitted with each other with one end surface being abutted against the shoulder of the outer joint member. The inner circumferential surface at the fitting portion of the hub wheel is formed with a hardened irregular portion. The hub wheel and the outer joint member are integrally connected via plastic deformation of the outer joint member. The hardened irregular portion bites into the outer circumferential surface at the fitting portion of the outer joint member by radially outwardly expanding the fitting portion of the outer joint member. The outer circumferential surface of the outer joint member is formed with a hardened layer at least at a region including the inner raceway surface and the shaft portion except for the fitting portion of the outer joint member.

摘要： A wheel bearing assembly is provided which has a rotating speed sensor unit which includes a seal for preventing entry of foreign matter and which takes up little space and thus can be mounted on the wheel bearing assembly without increasing the axial dimension of the fixed member of the wheel bearing assembly. The assembly includes a fixed member fixed to a vehicle body, and a rotary member rotatably supported in the stationary member through a bearing and mounted to a vehicle wheel. An annular sensor is fitted to a knuckle, which is a part of the fixed member, on the inboard side of the bearing. A sensor seal is fitted to the annular sensor and has a seal lip kept in slide contact with a seal land formed on a constant-velocity joint outer ring, which is a part of the rotary member, to define a sealed space on the inboard side of the bearing. An encoder is mounted on a bearing inner ring, which is a part of the rotary member, in the sealed space. The sensor element is disposed in the sealed space, opposite the encoder.
