摘要： Wedge angles are formed between mutually facing central track-groove portions (11b, 12b, 21b, 22b) of an outer joint member (1) and an inner joint member (2). Track grooves (11, 12) provided to the outer joint member (1) and track grooves (21, 22) provided to the inner joint member (2) include a first pair of track grooves (11, 21) respectively including the central track-groove portions (11b, 21b) forming therebetween the wedge angle (α) opening to an opening side of the outer joint member (1) under a state in which an operating angle is 0°, and a second pair of track grooves (12, 22) respectively including the central track-groove portions (12b, 22b) oppositely forming therebetween the wedge angle (β) opening to an inner-end side of the outer joint member (1) under the state in which the operating angle is 0° . Both the first track groove (11) and the second track groove (12) of the outer joint member (1) include opening-side track-groove portions (11c, 12c) connected respectively to the central track-groove portions (11b, 12b) directly, each of the opening-side track-groove portions (11c, 12c) being formed in such a shape as to be free from an undercut toward the opening side. Accordingly, it is possible to manufacture at low cost a high-efficient fixed type constant velocity universal joint which involves less torque loss.

摘要： A constant-velocity joint includes an outer ring formed formed with a bore defined by six flat surfaces parallel to its axis, and a trunnion member received in the bore of the outer ring. The trunnion member has an outer periphery formed with three first spherical surfaces circumferentially spaced apart from each other and three second spherical surfaces circumferentially spaced apart from each other and each disposed between adjacent first spherical surfaces. Each first spherical surface is in contact with one of the flat surfaces at a point offset from the circumferential center of the flat surface in one circumferential direction. Each second spherical surface is in contact with another flat surface at a point offset from the circumferential center of the flat surface in the other circumferential direction. At least one of the outer ring and the trunnion member is made of a synthetic resin.

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.

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： For butt-welding, which includes bringing joining end surfaces of a cup member and a shaft member into abutment against each other and radiating a high energy intensity beam from a radially outer side, the shaft member has a recess on a radially inner side of the joining end surface to obtain a welded portion having a closed hollow cavity on a radially inner side after butt-welding. The joining end surface (protruding surface) of the cup member protrudes toward a radially inner side with respect to an inner diameter of the joining end surface of the shaft member. With this, a welded portion of an outer joint member of a constant velocity universal joint, which is manufactured by joining the cup member and the shaft member, can be improved in strength and quality.
