  • Patent number: 7168902
    Abstract: A locking device for a threaded fastener comprises a pair of washers each having a plurality of wedge cam sets that include a base-cam and a raised tooth-cam. When the washers are mated together in use, the wedge cam sets of each washer are placed into confronting engagement with those of the other washer, with the raised tooth-cams of each washer engaging the base-cams of the other washer. The base-cam surfaces are ramped so that, as the tooth-cams slide along them during relative rotational movement, the combined axial height of the two washers changes—decreasing during tightening and increasing during loosening so that unintended partial loosening of the fastener is offset by expansion of the washers to thereby maintain bolt tension. Raised shoulders at each end of the tooth-cams are used to inhibit the amount of relative rotational movement of the two washers in both directions.

  • Patent number: 5873678
    Abstract: Vertical movement of a floating marine platform is reduced by tendons extending from the platform to anchors on the seabed. A final tension adjustment to equalize the load on all of the tendons is made by a respective tension adjustment mechanism incorporated into the top connector of each tendon. The tension adjustment mechanism includes a split load ring assembly having an upper ring and a lower ring. The upper ring and the lower ring abut each other at respective complementary surfaces. Each surface has a series of serrated ramps. A rotation of one ring with respect to the other causes the upper ring to climb over the lower ring to thereby increase the tension in the tendon. Rotation of the upper ring with respect to the lower ring, for example, is achieved by a motor driven gear ring.
