    摘要： Provided is a fixed type constant velocity universal joint of an eight-ball undercut-free type, which is capable of achieving an improvement of torque capacity at a high operating angle while ensuring durability at the time of a low operating angle. In the fixed type constant velocity universal joint of the eight-ball undercut-free type, a center of a track groove (32) of an outer joint member and a center of a track groove (35) of an inner joint member are separated from a joint center plane (P) respectively to both sides in an axial direction, and are offset to be positioned away from a joint center axis (X) to a radially opposite side relative to the track grooves (35). When Rt represents a distance between a center of a ball (37) and the center of the track groove (32) of the outer joint member, and F represents an axial distance between the joint center plane (P) and the center of the track groove (32) of the outer joint member, a ratio R1 between F and Rt is set to satisfy 0.061≦R1≦0.087, and, when fr represents a radial offset amount as a distance between the joint center axis (X) and the center of the track groove (32) of the outer joint member, a ratio R3 between fr and Rt is set to satisfy 0.07≦R3≦0.19.

The power transmission shaft according to the present invention includes a torque-transmission teeth portion (2) formed on an outer peripheral surface on an end portion side, and a smooth portion (3) formed on the outer peripheral surface adjacent to the torque-transmission teeth portion (2) so as to have a stepwise reduced diameter. A ratio of a minimum diameter (D3min) of the smooth portion (3) to a minimum diameter (D2min) of the torque-transmission teeth portion (2) is set to 0.9 or more and 1.02 or less. Further, the torque-transmission teeth portion (2) and the smooth portion (3) undergo heat treatment so as to from a heat-treated hardened layer (4). The heat-treated hardened layer (4) is formed to increase in depth from a side of the torque transmission teeth portion (2) to a side of the smooth portion (3). At least a minimum diameter portion (3a) of the smooth portion (3) undergoes full hardening for forming the heat-treated hardened layer (4) from a surface to an axis (X).

    摘要： A constant velocity universal joint is disclosed in which the end of a track groove 24 which opens to the open end surface 26 of the outer joint member 2 is formed with a cut portion 28a, 28b for the incorporation of a ball, thereby making the incorporation of balls possible without shifting the position of the open end surface 26. Therefore, the strength of the inlet portion of the outer joint member 2 is increased. Furthermore, since the ball incorporating angle .alpha. of the cage 5 can be decreased, it is possible to increase the width of the pocket column portion 58 of the cage 5 and increase the strength of the cage 5.

    摘要： A fixed type constant velocity universal joint of an eight-ball undercut-free type has improved torque capacity at high operating angle while ensuring durability at low operating angle. Centers of a track groove (32) of an outer joint member and a track groove (35) of an inner joint member are respectively separated from a center plane (P) toward axially different sides, and are offset away from a joint center axis (X) to a radially opposite side relative to grooves (35). When Rt represents a distance between a center of a ball (37) and the center of groove (32), and F represents an axial distance between plane (P) and the center of groove (32), a ratio R1 between F and Rt is 0.061≦R1≦0.087. When fr represents a radial offset amount as a distance between axis (X) and the center of groove (32), a ratio R3 between fr and Rt is 0.07≦R3≦0.19.
