    摘要： A novel constant velocity universal joint with eight ball is provided for realizing the improved durability of the joint under high-loaded conditions and the suppressed variations of lifetimes of the joints. The universal joint has an outer joint member having eight curved track grooves axially extending along an inner circumferential surface with a spherical shape, an inner joint member having eight curved track grooves axially extending along an outer circumferential surface with a spherical shape, eight balls respectively arranged in eight ball tracks provided as pairs of the track grooves of the outer joint member and the track grooves of the inner joint member, and a cage having pockets for respectively holding the balls. The center of each track groove of the outer joint member is axially displaced a predetermined distance from the spherical center of the inner circumferential surface. The center of each track groove of the inner joint member is axially displaced the same distance from the spherical center of the outer circumferential surface in the direction opposite to that of the outer joint member. A PCD gap in the ball track is in the range of 5 μm to 50 μm.

The power transmission shaft has coupling members respectively provided on the opposite ends of an pipe part made of a steel material. The steel material includes 0.30-0.45% by weight of C, 0.05-0.35% by weight of Si, 1.0-2.0% by weight of Mn, 0.05% by weight or less of Al, 0.01% by weight or less of S, and the remainder (iron Fe and unavoidable impurities). The pipe part has an electro-unite portion that extends in the axial direction. The electro-unite portion and neighborhood thereof are hardened so as to have a Rockwell hardness HRC of 45 or more. Also, another power transmission shaft has coupling members integrally formed on opposite ends thereof. In addition, the shaft is formed from a steel element tube by a plastic working. The shaft has an inner diametrical surface which is subjected to a high-frequency induction hardening and tempering treatment to make the surface portion hardness of the inner diametrical surface to have a Rockwell hardness HRC of 35 or more.

    摘要： A shaft member 1 and an outer peripheral member 2 disposed on the outer periphery of the shaft member 1 are joined together by splines 3 through which the teeth 31 of the shaft member 1 and the teeth 32 of the outer peripheral member 2 are fitted together. At one axial end of each spline 3, a trough 31 in the tooth 31 of the shaft member 1 is diametrically increased to provide a diametrically increased region S1. In this diametrically increased region S1, there is defined a fit region F for the tooth 31 of the shaft member 1 and the tooth 32 of the outer peripheral member 2.
