摘要： A spherical inner surface of the outer race and track grooves in the outer race are each defined by a post-hardening cut surface. A spherical outer surface of the inner race and track grooves in the inner race are also each defined by a post-hardening cut surface. A retainer has a spherical outer surface, a spherical inner surface and inner surfaces of the pockets, all of which are defined by a post-hardening cut surface. Respective surfaces of the retainer, the outer race and the inner race which contact with each other are formed with a surface treatment layer for reducing a frictional resistance.

摘要： The homokinetic joint accommodates variations in angle between two shafts. It incorporates an outer ring (1) with a spherical inner surface (2) with a series of curved grooves (3) accommodating balls (7). The balls are accommodated in a cage (8). There is an inner ring (4) with a spherical outer surface (5) with grooves in it to accommodate the balls. The cage has spherical inner and outer surfaces (9) which are a close fit with the spherical surfaces of the inner and outer rings between the grooves. The grooves in the inner and outer spherical surfaces are produced by plastic deformation of the metal, using tools of complementary shape to the grooves.

摘要： A power transmission shaft having an improved strength and ensuring a stable torsion fatigue strength. 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.

SOLUTION: The universal joint is applied to a uniform motion universal joint of fixed type for a propeller shaft. A spherical inside surface 5 of the outer ring 1 and the track groove 7 are mad a cutting surface after quenching. A spherical outside surface 6 of the inner ring 2 and the track groove 8 are also made the cutting surface after quenching. A holder 4 makes the spherical outside surface 10, the spherical inside surface 11 and an inner surface of a pocket 9 the cutting surface after quenching. A surface treatment layer for reducing the abrasion resistance is formed on the surface mutually coming into contact with the holder 4, the outer ring 1 and the inner ring 2.
