摘要： A constant velocity universal joint includes an inner roller and a trunnion. The inner roller has a chamfered portion formed by an inclined surface inclined at an angle not less than an assembling angle &thgr;. The inclined surface extends from a starting point defined by a crossing point of a spherical recess of the inner roller and a short radius r of an elliptic cutout formed on the inner roller.

摘要： A variety of cutout surfaces are formed on trunnions by cutting out parts of a spherical surface of each of the trunnions, to which no torque is applied. The cutout surfaces comprise a pair of opposite flat surface sections, bores, recesses or wide flat surfaces, and curved surface sections, for example.

摘要： A constant velocity joint, wherein all rolling elements annularly held by a tool are inserted into an inner diameter part from one end opposite to the flange part of a roller member along the axis of the inner diameter part of the roller member or the rolling elements remaining after one rolling element is removed from all rolling elements are charged into the inner diameter part and the removed one rolling element is inserted into a clearance between the rolling elements from the other end along the axis of the inner diameter part. After all rolling elements are fitted into the inner diameter part of the rolling member, a snap ring is fitted into an annular groove formed at the end part of the inner diameter part on the opposite side of the flange part to hold the rolling elements between the flange part and the snap ring.

摘要： An annular member is installed on a circular cylinder section of a trunnion, and a roller member, in the inner periphery of which a needle bearing is held, is installed on the circular cylinder section. The needle bearing is held between a flange section formed on one end of the roller member and the annular member installed on the trunnion with a predetermined gap between them. Further, a gap (X) between the needle bearing and the annular member is set to satisfy the following relationship. X>R/2·(1/cos θ max−1) where R: Radius of rotation of the center of the roller member relative to the center axis of an outer member. θ max: Maximum inclination angle of an inner member.

摘要： A constant velocity joint, wherein all of those rolling elements excluding a plurality of rolling elements are divided into a plurality of rolling element groups and arranged along the inner diameter part of a roller member. The excluded plurality of rolling elements are dispersed in first to third cam grooves at intervals in the circumferential direction. When the rolling elements are pressed in the radial outer direction by the first to third pressing faces of a cam rotating in the arrow A direction, they are simultaneously press-fitted into first to third clearances between the rolling elements from the side of the inner diameter part of the roller member.
