摘要： A constant velocity universal joint shaft, capable of suppressing a rotational backlash when incorporated in the constant velocity universal joint, and improving the assembly efficiency as well as reducing the manufacturing cost, is to be provided. The present invention relates to the constant velocity universal joint shaft having a spline that fits an inner race of the constant velocity universal joint. The shaft includes a shaft body with a spline formed thereon, and a yoke portion with a ring-shaped fitting portion. The shaft body and the yoke portion are integrally formed of medium carbon steel. By a pressing force of a pressing member the fitting portion of the yoke portion is tightened, so that such fitting portion fits a shaft external to the joint. In the constant velocity universal joint, the pressing member and an abutment member are elastically butted via an elastic member, so that a ball constantly remains in contact with a raceway of an outer member and a raceway of an inner member.

摘要： To prevent inverting of a mountain portion of a bellows member when a rotating shaft is angularly displaced, the boot includes a bellows member with large and small diameter mounting members. A first mountain portion nearest the large diameter mounting member rises from the large diameter mounting member. A length (L1) between a top of the first mountain portion and a bottom at the large diameter mounting member side is not more than a length (L2) between the inner peripheral position of the bottom and an end portion of an outer ring at the rotating shaft side. A first valley portion adjacent to the first mountain portion is positioned at the rotating shaft side from the end part.

摘要： A fixed type constant velocity joint includes an outer ring (1), an inner ring (2), torque transmitting balls (3), a cage (4), and a pre loading mechanism in which either a pressing section for axially applying an elastic pressing force or a receiving section for receiving the pressing force from the pressing section is disposed in the cage (4), the other being disposed in the inner ring (2). The axial clearance between the inner ring (2) and the cage (4) is greater than the axial clearance which is due to the radial clearance of the track, and the axial clearance which is produced by the radial clearance of the track is 2.5-6.5 times as large as the radial clearance of the track. Further, the center of the outer spherical surface (2b) of the inner ring (2) is shifted to the spread side of the ball tracks (1a, 2a) over the center of the inner spherical surface (4b) of the cage, thereby improving the cross operation.

摘要： An outer joint member (10) and an inner joint member (40) each have a shaft portion (18 and 46) having a male spline formed thereon, and shaft clamps (60) are press-fitted onto the respective shaft portions (18 and 46). Each of the shaft clamps (60) includes: a connection hole (66) that has a female spline formed therein, extends from a first axial end partway toward a second axial end, and has no quench-hardened layer; and a cylindrical portion (64) that has no female spline formed therein and extends from the second axial end partway toward the first axial end. The shaft portions (18 and 46) each have a quench-hardened layer on the outer circumference thereof. The inner diameter of the connection hole (64) at a portion having no female spline formed therein is less than the outer diameters of the shaft portions (18 and 46).

摘要： To make a bellows section of a boot to be flexibly and repeatedly deformable without deterioration in durability, to thereby reduce rotational resistance when a joint angle is large, the boot has the bellows portion where three or more circumferentially extending crest portions and root portions therebetween are alternately formed. A large-diameter attaching portion is formed at one end of the bellows portion. A small-diameter attaching portion is formed at the other end. A rising wall closest to the large-diameter attaching portion and a rising wall closest to the small-diameter attaching portion have smaller wall thickness than other portions of the bellows section. A ratio (t1/t2) of the thickness (t1) of the rising walls to the thickness (t2) of the other portions of the bellows portion is set to 0.6≦t1/t2
