  • Patent number: 10215222
    Abstract: A universal joint comprising a first band, a second band, and a third band. The three bands are cylindrical bands coaxial with one another with respect to a common axis. The first band and the second band are separated by a first slot, and the second band and the third band are separated by a second slot. Two connection points, which are diametrically opposed, assure the connection of the first band and of the second band. Two other connection points, which are diametrically opposed, assure the connection of the second band and of the third band. The two connection points between the first band and the second band are offset by substantially 90° in rotation about the common axis with respect to the two connection points between the second band and the third band.

  • Patent number: 6682432
    Abstract: Compression exerted by a clamp collar integral to a molded plastic flexible shaft coupling accommodating angular shaft misalignment upon the circumferential outward surface of a radially compressible molded sleeve insert located in a shaft bore of the flexible coupling facilitates engagement of a reduced diameter shaft located within the sleeve insert. Use of a sleeve insert having a different internal diameter similarly accommodates flexible coupling to another diameter shaft. Utilization of sleeve inserts selected from a plurality of different reduced internal diameters and exterior diameters sized to fit either shaft bore enables flexible coupling of both multiple matched shaft diameters and an exponential number of differing opposed shaft diameter combinations within a range limited by the flexible coupling shaft bores. Radial compressibility of the sleeve insert is facilitated by the utilization of resilient material, interruption of the circumferential extension by a longitudinal slot, or both.

  • Patent number: 6261182
    Abstract: An installation structure of a rotation detector for detecting a rotation amount of a rotational shaft such as a kingpin. The installation structure prevents wear and damage to an input shaft of the rotation detector caused by a radial force applied to the input shaft and has high detection accuracy by eliminating slack between the rotational shaft and the input shaft. The rotation detector is fixed to a support member rotatably supporting the rotational shaft such that the input shaft is substantially coaxial with the rotational shaft. The input shaft is coupled to the rotational shaft through a rotation transmitting means. The rotation transmitting means permits the axis of the input shaft to be offset from the axis of the rotational shaft and limits relative rotation between the input shaft and the rotational shaft.
