  • Patent number: 5704838
    Abstract: A universal joint assembly (12) includes a coupling hub member (26) and a female coupling member (24). The female coupling member (24) includes a receptacle (28) at one end for receiving a pivot end (30) of the coupling hub member (26). The joint (12) includes a central bearing structure (34) interposed between the coupling hub member (26) and female coupling member (24) for enabling the coupling members to pivot up to a maximum pivot angle with respect to each other about a coupling axis. The universal joint (12) also includes a plurality of torque transmitting rollers (50), each received in a different roller slot and spaced apart about the periphery of the coupling hub member (26) near its pivot end (30). The roller slots are formed on both the coupling hub member (26) and female coupling member (24) and enable the torque transmitting rollers (50) to transmit torque between the coupling members while rolling with respect to the roller surfaces as the coupling members pivot about the coupling axis.

  • Patent number: 5692960
    Abstract: The homokinetic joint has an inner ring and and an outer ring formed with axial track grooves so as to be opposite to each other, balls received in the track grooves, a cage mounted between the inner and outer rings and having pockets accommodating the respective balls, whereby torque is transmitted between the inner and outer rings through the balls so that the inner and outer rings will rotate at the same speed. The distance between said track grooves formed in the inner ring and those formed in the outer ring is determined so that the balls are fitted in the grooves between the ring and the inner ring with a predetermined interference, while leaving an axial clearance between the pockets of the cage and the balls. Thus, the balls can roll smoothly with little play in the direction of rotation.

    Abstract: A cage for a constant velocity universal joint has an increase in the fracture strength of the cage and thus the torque capacity of the entire constant velocity universal joint. This is achieved in that the apertures for the windows in the cage at the circumferentially extending contact faces do not extend parallel to the central axis but contact a virtual sphere arranged at the point of intersection between the radial center plane of the cage and the joint axis. As a result, the webs of the cage comprise a larger cross-section and in consequence, its fracture strength is improved.

  • Patent number: 5368523
    Abstract: A fixed constant velocity universal joint having direct spherical contact and support between inner and outer race members to prevent axial movement has inserts which can be replaced, when worn, with new inserts. The universal joint includes an inner race member having a plurality of recesses and an outer race member with a plurality of recesses, each containing one of the inserts. Bearing balls are located in grooves in the inserts which are so arranged that they require axial support in one direction only by a retainer which is fully enclosed in the universal joint and abuts the bearing balls. A seal engages the inner and outer race members on the side of the bearing balls opposite the retainer. The seal includes a base held in an annular recess in the outer race member and at least one resilient finger engaging a partially spherical surface on the inner race member.

  • Patent number: 5334096
    Abstract: In a mechanical element such as a uniform velocity type universal joint having an inner joint member and one of a plurality of spherical ball elements or an outer joint member and one of the spherical ball elements, the ball rolls and slides on the surface of either or both of the inner and outer joint members thus generating relative harmonic vibrations due to a frictional force generated thereon by the sliding contact between the ball and the joint members. To reduce high-frequency harmonic vibrations, a pair of piezoelectric actuators are installed between a flange of one rotation axle of the (constant) uniform velocity type universal joint and the outer joint member and/or between a mounting bolt head of the universal joint and the outer joint member.

  • Patent number: 5292285
    Abstract: A cross groove variety of constant velocity universal joint includes an inner race having a plurality of grooves formed in an outer surface thereof and an outer race having a plurality of grooves formed in an inner surface thereof. For each pair of associated inner and outer race grooves, the inner race groove is inclined in one direction relative to the rotational axis of the joint, while the outer race groove is inclined in the opposite direction. A ball is disposed in each of the associated inner and outer race grooves for providing a driving connection between the inner and outer races.
