摘要： An annular support ring 32 is fitted onto the outer periphery of each trunnion 22. This support ring 32 and the roller 34 are unitized via a plurality of needle rollers 36 to constitute a roller assembly capable of relative rotations therebetween. In longitudinal section, each trunnion 22 has an outer periphery of straight shape, parallel to the axis of the trunnion 22. In cross section, the trunnion 22 has a generally ellipse shape with the major axis orthogonal to the axis of the joint. The inner periphery of each support ring 32 is arcuate and convex in section. This combines with the general elliptic cross sections of the trunnions 22 and the provision of predetermined clearances between the trunnions 22 and the support rings 32, to allow the support rings 32 to move along the axial directions of the trunnions 22 as well as make tilting movements with respect to the trunnions 22.

摘要： A perpendicular distance (PCR1) between a centerline (L1) including the center (O3) of the outer circumference surface (4b) of an outer roller (4), orthogonal to axis Z of a trunnion (2a) and a joint center O is shifted by &Dgr;h (=PCR1−PCR2) from a perpendicular distance (PCR2) between a centerline (L2) including the center (O1) of the outer circumference surface (3b) of an inner roller (3), orthogonal to axis Z of a trunnion (2a) and a joint center O. Under the most favorable conditions, PCR2 is shifted by an optimal amount of &Dgr;H from PCR1 toward the proximal end of the trunnion, and the position of contact (S) between the inner circumference surface (4a) of the outer roller 4 and the outer circumference surface (3b) of the inner roller (3) is located on the centerline (L1) (on PCR1) of the outer circumference surface (4b) of the outer roller (4).

摘要： The tripod member has three trunnions which are projected radially. Each of the trunnions carries a roller, and this roller is accommodated in one of the track grooves in the outer joint member. The outer peripheries of the rollers and the roller guideways make angular contact with each other. Support rings are fitted onto the outer peripheries of the trunnions. These support rings and the rollers are assembled (unitized) via a plurality of needle rollers to constitute roller assemblies capable of relative rotations. In longitudinal sections, the outer peripheries of the trunnions have straight shapes parallel to the axes of the trunnions. In cross sections, the outer peripheries are elliptic in shape, with their respective major axes perpendicular to the axis of the joint. The inner peripheries of the support rings have arcuate convex sections.
