摘要： Six track grooves formed in a spherical inner peripheral surface of an outer joint member are each formed into an arc shape having a curvature center at a joint center. The track grooves are inclined in a circumferential direction of the outer joint member with respect to a joint axial line, and are adjacent to each other in the circumferential direction with their inclination directions opposite to each other. Six track grooves formed in a spherical outer peripheral surface of an inner joint member are formed so as to be mirror-image symmetrical with the track grooves paired therewith of the outer joint member with respect to a joint center plane at an operating angle of 0°. An inclination angle of each of the track grooves of the outer joint member with respect to the joint axial line is set to 8° or more and 16° or less.

摘要： A fixed type constant velocity universal joint of a track groove crossing type has track grooves of an inner joint member formed to be mirror-image symmetrical with paired track grooves of an outer joint member with respect to a joint center plane at an operating angle of 0°. The track grooves of both the joint members each have a length corresponding to a maximum operating angle (θmax) required for a propeller shaft, and surface treatment is performed, for example, on a defined surface of each of the track grooves of the outer joint member so as to reduce frictional resistance (sliding resistance) against balls.

摘要： In a fixed type constant velocity universal joint, track grooves of an outer joint member include first and second track groove portions positioned on interior and open sides, respectively. Each of the first track groove portions includes an arc-shaped ball raceway center line having a curvature center 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 opposite to each other in the first track groove portions, which are adjacent to each other in a peripheral direction of the outer joint member. Each of the second track groove portions includes a ball raceway center line having a straight part when being projected onto corresponding one of the planes.
