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.

摘要： A shaft coupling includes plates fitted on ends of input and output shafts, respectively. A plurality of guide grooves are formed in the opposed surfaces of the plates, respectively, so that each of the grooves extends perpendicular to the corresponding groove formed in the other plate. A steel ball is disposed between each pair of guide grooves of the plates at a portion where the pair of grooves cross each other. When the steel balls are pushed by the driving plate, they push the driven plate while rolling in the guide grooves, with their movements restricted by a retainer in the radial direction of the plates. Thus, large power can be smoothly transmitted between the rotary members with less frictional resistance. The offset amount can be changed easily. Between the plates, there are only the steel balls and the retainer.
