    摘要: A shaft portion of a joint outer ring where projections extending in an axial direction are provided is press-fitted into a hole portion of a hub wheel to thereby form recesses by the projections in an inner diameter surface of a shaft fitting hole of the hub wheel, by which a recess-projection fitting structure is constructed. An entire area of fitting sites of the projections and the recesses are brought into close contact. Moreover, a bolt member is fastened in a bolt hole provided in the shaft portion of the joint outer ring after the construction of the recess-projection fitting structure, which restricts separation between the hub wheel and the joint outer ring. As the bolt member, if an outer diameter of a seating surface thereof is d1 and a shaft diameter is d2, a bolt member satisfying a relational expression of 2.3≦(d1/d2)2≦4.9 is used.

    摘要: An object of the present invention is to enhance assemblability of a wheel bearing device, and stably maintain predetermined torque transmissibility over a long period of time. A shaft portion (12) of a joint outer ring (5) where projections (35) extending in an axial direction are provided is press-fitted into a hole portion (22) of a hub wheel (1) to thereby form recesses (36) by the projections 35 in an inner diameter surface (37) of a shaft fitting hole 22a of the hub wheel (1), by which a recess-projection fitting structure M is constructed, where an entire area of fitting sites of the projections (35) and the recesses (36) are brought into close contact. Moreover, a bolt member (50) is fastened in a bolt hole (13) provided in the shaft portion (12) of the joint outer ring (5) after the construction of the recess-projection fitting structure (M), which restricts separation between the hub wheel (1) and the joint outer ring (5). As the bolt member (50), if an outer diameter of a seating surface thereof (50a1) is d1 and a shaft diameter is d2, a bolt member satisfying a relational expression of 2.3≦(d1/d2)2≦4.9 is used.

    摘要: Provided is a bearing device for a wheel capable of suppressing a backlash in a circumferential direction, excellent in coupling workability of a hub wheel and an outer joint member of a constant velocity universal joint, and excellent in strength owing to stable fitting between the hub wheel and the outer joint member of the constant velocity universal joint. An axle module using such bearing device for a wheel is also provided. Projecting portions extending in an axial direction are provided on one of an outer surface of a shaft section of the outer joint member and an inner surface of a hole portion of the hub wheel. The projecting portions are press-fitted into the other along the axial direction, and recessed portions are formed in the other through press-fitting of the projecting portions. Thus, a recess-projection fitting structure is formed, in which the projecting portions and the recessed portions are held in close contact with each other through an entire region of fitting contact regions therebetween. Hardness of at least press-fitting start end portions of the projecting portions is set to be higher than hardness of a recessed-portion forming region. A hardness difference therebetween is set to be equal to or larger than 20 points in HRC.

    摘要: Provided is a small-sized, lightweight, low-cost, and highly reliable bearing device for a driving wheel which needs no tapered spline, and eliminates a circumferential backlash in spline fitting portions to thereby prevent unusual noise. The bearing device for a driving wheel comprises an outer race (5) having an inner periphery in which double-row outer raceway surfaces (13, 14) are formed; a hub wheel (1) and an inner race (2) having outer peripheries in which double-row inner raceway surfaces (7, 8) opposed to the outer raceway surfaces (13, 14) are formed; and double-row rolling elements (3, 4) interposed between the outer raceway surfaces (13, 14) of the outer race (5) and the inner raceway surfaces (7, 8) of the hub wheel (1) and the inner race (2). A shaft hole (28) of the hub wheel (1) is formed into a cylindrical shape, and a male spline (26) is formed on an outer periphery of a stem section (27) of the outer joint member (15) so that the stem section (27) of the outer joint member (15) is press-fit into the shaft hole (28) of the hub wheel (1). With this, recesses caused to closely fit on the male spline (26) with interference are formed in the shaft hole (28) of the hub wheel (1), whereby the hub wheel (1) and the outer joint member (15) are separably coupled to each other.
