  • Patent number: 6158302
    Abstract: A torque support, especially for wheel blocks, is arranged between a gear unit housing with a drive shaft and a driven unit housing. The torque support includes a plate-shaped base body which is detachably fastened to the gear unit housing with fastening elements. The plate-shaped base plate has at least two fastening locations comprising through openings for fastening the torque support to the driven unit housing. To keep the shearing forces resulting from the torque support and acting on the gear shaft small while the torsional moment is simultaneously absorbed with low play and in such a way that load peaks are damped, a corresponding plastic ring body is inserted into each through-opening in a positive-locking engagement. A side of the plastic ring body facing the driven unit housing has an edge area which widens radially outward forms an elastic disk element arranged between the driven unit housing and the torque support.

  • Patent number: 6065920
    Abstract: A securing ring, includes a body defining a ring opening and having a circumference of substantially circular configuration at formation of a slotted gap to define confronting ring ends. The body defines a ring plane and an axis of symmetry and has a radial width which continuously increases, at least in sections, from the ring ends onwards at both sides of the axis of symmetry. Each of the ring ends has a L-shaped configuration and is extended by a lug jutting out from the ring plane and formed with a throughbore. Both lugs of the ring ends are positioned on a same side of the ring plane, with the throughbores of the lugs extending in parallel relationship to one another and to the ring plane.
