The constant velocity universal joint includes an outer joint member having an inner spherical surface (1) in which multiple track grooves (2) are formed; an inner joint member having an outer spherical surface (4) in which multiple track grooves (5) paired with the track grooves (2) of the outer joint member are formed; multiple balls (7) interposed between the track grooves (2) of the outer joint member and the track grooves (5) of the inner joint member so as to transmit torque; and a cage (9) interposed between the inner spherical surface (1) of the outer joint member and the outer spherical surface (4) of the inner joint member so as to retain the balls (7). A tapered relief portion (17) retracted with respect to the outer spherical surface (4) is formed with low curvature at a back end portion (4a) of the outer spherical surface (4) of the inner joint member so as to be smoothly continuous with the outer spherical surface (4).

    摘要： Provided is a fixed type constant velocity universal joint (1) of a track groove crossing type, in which track grooves (7) of an outer joint member (2) are each formed into an arc shape having a curvature center at a joint center (O), the track grooves (7) being inclined in a peripheral direction of the outer joint member (2) with respect to a joint axial line (N-N) and being adjacent to each other in the peripheral direction with their inclination directions opposite to each other, and in which track grooves (9) of an inner joint member (3) are formed so as to be mirror-image symmetrical with the paired track grooves (7) of the outer joint member (2) with respect to a joint center plane (P) at an operating angle of 0°.

Further, each axial clearance (ΔSia1, Δsia2) between the inner joint member (3) and the cage (5) is set larger than an axial clearance (ΔTao+ΔTai) formed by a ball track clearance (ΔT) between each of balls (4) and each track groove (7, 9).

    摘要： A joint arrangement (2) comprises an outer joint component (4), an inner joint component (6), a cage (8) and at least two balls (10) located between the outer and inner joint component and in openings (14) of the cage. The balls run in ball recesses, while at least two are in a mechanical contact with pressing devices (12), which are adapted for holding the respective balls in a radially flexible position relative to one of the inner joint component, the outer joint component and the cage and for pressing the respective balls into the corresponding recesses. Such a joint arrangement is based on a homokinetic joint and allows a homogenous transfer of torque without alternating acceleration and deceleration due to the action of the joint itself. Furthermore, a reliable and effective torque limitation may be accomplished.
