    摘要： A heat treatment method is capable of molding, by mobile quenching of induction quenching, an outer joint member of a tripod type constant velocity universal joint having excellent strength without forming hardened layers in larger radially-inner portions. Mobile quenching is performed in such a manner that a high-frequency induction heating coil is moved in an axial direction relative to an outer joint member, and thus hardened layers are formed on the roller guide surfaces. Magnetic field line cut-out bodies for cutting out generated magnetic field lines are arranged on the high-frequency induction heating coil. The larger radially-inner portions become an unquenched portion by cutting out the magnetic field lines with the magnetic field line cut-out bodies.

    摘要： A tripod constant velocity universal joint is configured with only three parts including an outer ring (10), a tripod (20), and spherical rollers (30). Trunnions (26) are allowed to make direct contact with the spherical rollers (30). The outer ring (10) includes three track grooves (14) parallel to its axis in the inner circumference thereof. Roller guide surfaces (16) are formed on both side walls of the respective track grooves (14). The tripod (20) is inserted inside the outer ring (10) and composed of a boss (22) and three trunnions (26) protruding radially from the boss (22). The spherical rollers (30) are rotatably supported on the trunnions (26), and can move in the axial direction of the outer ring (10) as they roll in the track grooves (14) of the outer ring (10) along the roller guide surfaces (16).

    摘要： Proposed are a heat treatment method capable of molding, by mobile quenching of induction quenching, an outer joint member of a tripod type constant velocity universal joint excellent in a strength thereof without forming hardened layers in larger radially-inner portions, and the outer joint member and the tripod type constant velocity universal joint which are manufactured by the above-mentioned heat treatment method. Mobile quenching is performed in such a manner that a high-frequency induction heating coil (51) is moved in an axial direction relative to an outer joint member (21), and thus hardened layers (S) are formed on the roller guide surfaces (27) of the outer joint member (21). Magnetic field line cut-out bodies (A) for cutting out magnetic field lines generated through the high-frequency induction heating coil are arranged on the high-frequency induction heating coil (51), and each of the larger radially-inner portions (46) of the outer joint member (21) becomes an unquenched portion (50) by cutting out the magnetic field lines with the magnetic field line cut-out bodies (A).

    摘要： In a no-flange type outer joint member, the amount of abrasion in a large inner diameter portion formed for a track groove is intended to be restrained. In a tripod type constant velocity universal joint including: a no-flange type outer joint member; and a roller assembly including a roller, being attached to a trunnion so as to be capable of oscillating, hardened layers are formed on portions of a large inner diameter portion of the outer joint member, which are in contact with an inclined roller assembly. In this case, a value of F/D is set equal to or less than 0.45, where a distance from a center of the track groove of the outer joint member to the ends of both the hardened layers on the side of the center of the track groove is F, and a diameter of an outer circumference of the roller assembly is D.

    摘要： A tripod type constant velocity universal joint includes an outer joint member including three track grooves having roller-guide surfaces arranged to face each other in a circumferential direction, a tripod member including three leg shafts projecting in a radial direction, and roller units each including a roller and an inner ring for supporting the roller in a freely rotatable manner. The inner ring is externally fitted to corresponding one of the three leg shafts. The roller is movable along the roller-guide surfaces of corresponding one of the three track grooves. Each of the three leg shafts includes a region formed into a substantially circular-arc shape in horizontal cross-section that is orthogonal to an axial line of the each of the three leg shafts.
