    摘要： A bearing device for a wheel enabling the easy control of quality since there is no possibility of cracking even if caulking is applied thereto. The bearing device comprises an outer ring having double rows of raceway surfaces on the inner periphery thereof, an inner member having raceway surfaces opposed to the raceway surfaces, and balls interposed between the double rows of raceway surfaces opposed to each other. The inner member further comprises a HUB ring and an inner ring. Caulking is applied to the HUB ring to join it to the inner ring. The grain size number of the austenite grains of a caulked section is at least 6.

    摘要： A joint outer ring of a constant-velocity joint has a stem portion protruding from of a cup portion and inserted to a through hole of a hub in a bearing device. The joint outer ring has an abutment face abutting against an end face of a bearing inner ring fitted to an outer periphery of the hub in an outer bottom face of the cup portion, and is composed of a forged product of a steel material. The joint outer ring has a base material portion composed of a standard structure and an outer surface layer partially formed as a non-standard structure portion. The non-standard structure may be a tempered martensite structure, or a mixed structure including the tempered martensite structure and at least one of an upper bainite structure and a lower bainite structure.

    摘要： A vehicle wheel bearing apparatus which can increase the strength and durability of the hub wheel under rotary bending conditions as well as lighten the apparatus without changing the configuration and dimension of the wheel mounting flange and without causing surface run-out has an outer member formed with double row outer raceway surfaces on its inner peripheral surface. An inner member is formed with double row inner raceway surfaces arranged opposite to the double row outer raceway surfaces. Double row rolling elements are freely rollably contained between the outer and inner raceway surfaces, respectively, of the outer and inner members. A wheel mounting flange is integrally formed with either one of the outer or inner members. At least one of the outer and inner members, on which the wheel mounting flange is formed, is heat treated and their raceway surfaces are hardened by quenching to a predetermined surface hardness.

    摘要： A vehicle wheel bearing apparatus has an outer member formed with a body mounting flange on its outer circumferential surface. The body mounting flange is to be mounted on a knuckle of the vehicle. The outer member inner circumference includes double row outer raceway surfaces. An inner member includes a wheel hub with a wheel mounting flange formed on one end. A cylindrical portion extends from the wheel mounting flange. At least one inner ring is press-fit onto the cylindrical portion of the wheel hub. The inner ring outer circumference is formed with an inner raceway surface arranged opposite to the double row outer raceway surfaces. Double row rolling elements are freely rollably contained between the outer raceway surfaces and inner raceway surfaces of the outer member and the inner members. Seals are mounted within annular openings formed between the outer member and the inner member. The inner ring is axially secured relative to the wheel hub by a caulked portion. The caulked portion is formed by radially outwardly plastically deforming the end of the cylindrical portion of the wheel hub. Outer side rolling elements of the double row rolling elements are balls. The inner side rolling elements of the double row rolling elements are tapered rollers. The fundamental rated load of the inner side row of tapered rollers is set larger than that of the outer side row of balls.
