    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： A fixed constant velocity joint is provided, which is suitable for an application where a rotational backlash should be avoided. A pressing member is attached to a shaft, and simultaneously a receiving member is attached to a cage. Then, an elastic force of an elastic member elastically bring a pressing part of the pressing member in contact with a receiving part of the receiving member. As a result, an inner race and a cage relatively travel in the axial direction, balls are pushed toward a direction along which wedge-shape ball tracks narrow, and consequently a track clearance in the axial direction decreases.

    摘要： In a fixed type constant velocity universal joint, track grooves of an outer joint member include first track groove portions positioned on an interior side and second track groove portions positioned on an opening side. The first track groove portions each have an arc-shaped ball raceway center line having a curvature center that is prevented from being offset in an axial direction of the outer joint member with respect to a joint center. Planes each including at least the ball raceway center line and the joint center are inclined with respect to a joint axial line with their inclination directions alternately opposite to each other in the first track groove portions that are adjacent to each other in a peripheral direction of the outer joint member.

    摘要： An object of the present invention is to ensure the miniaturization, strength, durability, load-carrying capacity, and an operating angle of a constant velocity universal joint. Six balls 3 are disposed in the constant velocity universal joint. The ratio r1 (=PCDBALL/DBALL) between the pitch circle diameter PCDBALL (PCDBALL=2×PCR) of the ball 3 and the diameter DBALL thereof is set in a range of 1.5≦r1≦4.0. The ratio r2 (=DOUTER/PCDSERR) between the outside diameter DOUTER of an outer member 1 and the pitch circle diameter PCDSERR of serrations (or splines) 2d of an inner joint member 2 is set in a range of 3.0≦r2≦5.0.
