Abstract: A fixed type constant velocity universal joint secures smooth rotation and reduces a load on a cage even at a large operating angle and when bearing large torque. The universal joint includes an outer joint member having an inner spherical surface in which track grooves are circumferentially formed in an axial direction and an inner joint member having an outer spherical surface in which track grooves paired with the track grooves of the outer joint member are circumferentially formed in the axial direction and multiple outer spherical surface portions circumferentially arranged. Balls are interposed between the track grooves of the outer and inner joint members for transmitting torque. A cage is interposed between the inner spherical surface and the outer spherical surface for retaining the balls. A spherical surface angle of the outer spherical surface on a joint opening side is set to 12.5° or more.

Abstract: A fixed type constant velocity universal joint is capable of securing a ball groove depth larger than conventional products and enhancing performance without an increase in a “force of pushing out balls in an axial direction”, the force having an influence on joint efficiency. In the fixed type constant velocity universal joint, a center of each of a plurality of guide grooves of an outer joint member and a center of each of a plurality of guide grooves of an inner joint member are offset with respect to a spherical surface center of an inner surface and a spherical surface center of an outer surface. A ratio (F/PCR) of an offset amount F to a length of a segment (PCR) ranges from 0.045 to 0.065. A ratio (αt/α) when an angle α is the total of an angle αt and an angle αc ranges from 0.45 to 0.65.

Abstract: Constant-velocity fixed joints may comprise an outer joint part with outer ball tracks, an inner joint part with inner ball tracks, torque transmitting balls which are guided in pairs of tracks each formed of an outer and an inner ball track, and a ball cage with circumferentially distributed cage windows in which the balls are received. Here, the balls are held in a common central plane and are guided onto the bisecting plane when the joint is deflected. Constant-velocity rotary joints of this type are known as Rzeppa fixed joints (RF) or as undercut-free fixed joints (UF).

Abstract: Wedge angles are formed between mutually facing central track-groove portions (11b, 12b, 21b, 22b) of an outer joint member (1) and an inner joint member (2). Track grooves (11, 12) provided to the outer joint member (1) and track grooves (21, 22) provided to the inner joint member (2) include a first pair of track grooves (11, 21) respectively including the central track-groove portions (11b, 21b) forming therebetween the wedge angle (α) opening to an opening side of the outer joint member (1) under a state in which an operating angle is 0°, and a second pair of track grooves (12, 22) respectively including the central track-groove portions (12b, 22b) oppositely forming therebetween the wedge angle (β) opening to an inner-end side of the outer joint member (1) under the state in which the operating angle is 0° . Both the first track groove (11) and the second track groove (12) of the outer joint member (1) include opening-side track-groove portions (11c, 12c) connected respectively to the central track-groove portions (11b, 12b) directly, each of the opening-side track-groove portions (11c, 12c) being formed in such a shape as to be free from an undercut toward the opening side. Accordingly, it is possible to manufacture at low cost a high-efficient fixed type constant velocity universal joint which involves less torque loss.

Abstract: The present invention provides a constant velocity universal joint component and a manufacturing method thereof capable of achieving increased strength without significant procedural changes, and that can contribute to size reduction and weight reduction. In the constant velocity universal joint component of the present invention, a sharp-angled portion 15 is formed by machining after cold plastic working is applied. A carburization process is then performed in which surface carbon concentration of 0.45 mass % to less than 0.60 mass % is obtained. Quenching is then performed. High-frequency induction hardening is subsequently performed.
