    Abstract: A disclosed constant velocity joint includes an outer ring including an annular space with an open end, plural outer grooves axially extending in an outer wall of the annular space and being equally spaced from each other in a circumferential direction, and plural inner grooves axially extending in an inner wall of the annular space and facing the respective outer grooves; and a cage configured to hold balls that slide along the inner walls and the outer walls. The outer ring and/or the cage is made of a synthetic resin. A drive force of one of the cage and the outer ring is transmitted to the other one of the cage and the outer ring when part of the cage is inserted in the annular space and the balls held by the cage are engaged in the inner grooves and the outer grooves.

    Abstract: The pocket 4a of the retainer 4 comprises a pair of axial walls 4a1 opposed in the axial direction of the retainer 4, a pair of circumferential walls 4a2 opposed in the circumferential direction, and corner round sections 4a3 connecting the axial wall 4a1 and the circumferential wall 4a2. The ratio (R/d) of the radius of curvature R of the corner round section 4a3 to the diameter d of the torque transmission ball 3 is set in a range of 0.45?R/d?0.62. Also, the circumferential wall 4a2 and the corner round sections 4a3 are drawn in a single arc with the radius of curvature R. Furthermore, as to the axial walls 4a1, grinding, cutting by quenched steel, or the like is carried out after the heat treatment (carburizing and quenching) of the retainer 4 in order to reduce variations in a processing margin.

  • Patent number: 6685571
    Abstract: My universal joint will use the outer and inner members to hold the balls in alignment. The male or female part would hold the ball in a half spherical recess and the other component would have a race groove to allow movement. It will also have means of attachment on each end with both ends being integral components of the final product. The male and female components could be made out of a pipe, tube, bar or cylinder of any length desired. The male component could consist of the unit holding 3 balls. This method would turn the friction wear of a rubbing surface into a rolling movement that would allow more speed of motion and less vibration. If necessary, in order to provide more bearing surface, increase torque, speed and reduce vibrations, it would be possible to use several paired ball tracks and ball seats. The center ball would impart rolling movement to all balls in contact with the ball race.

  • Patent number: 6267683
    Abstract: The invention relates to an assembly having a constant velocity joint (1) and a receiving part (16). The constant velocity joint (1) comprises an outer part (2), an inner part (7), a cage (12) and balls (13). The outer part (2), on its outer face, is provided with a centering face (14) by means of which the outer part (2) is centrically received in a centering bore (17) of a receiving part (16). The flange (5) is tensioned against a contact face of the receiving part (16) by fixing bolts (20). The outer part (2) is produced from plate metal by a non-chip producing forming operation. Because of the type of arrangement, it can be correspondingly lighter in weight than a solid part incorporated for the transmission of the same amount of torque.

  • Patent number: 6206785
    Abstract: A non-stroking constant velocity universal joint including an inner joint member, an outer joint member, and a plurality of torque transferring bearing spheres in facing pairs of ball grooves in the inner and outer joint members. The bearing spheres are maintained in a common plane bisecting the angle of articulation between the inner and outer joint members by a cage consisting of a pair of hollow hemispherical segments (“hemi-segments”) clamped radially against each other by the outer joint member. Interlocking lugs and notches on the hemi-segments prevent relative linear translation therebetween. The hemi-segments are made from flat blanks which are perforated for the cage windows and then plastically deformed to the shape of the hemi-segments. The cage is assembled around the inner joint member and may, therefore, have dimensions which reduce unit stresses in the cage and preclude assembly of the inner joint member into the cage through a circular open end of the cage.

The spherical surface parts act as sliding faces. The outer joint part includes inner surface parts which are interrupted by the tracks and which act as guiding faces. When the joint is articulated, the surface parts which act as guiding faces, supportingly act on the surface parts acting as sliding faces around at least one fulcrum positioned on the longitudinal axis of the outer joint part.
