    摘要: A rotationally elastic coupling has a first coupling part with elastomers. The elastomers are arranged in the first coupling part in such a way that the elastomers serve to transfer a force onto a second coupling part when the first coupling part and the second coupling part are connected to one another. In order to improve the identification of wear, the rotationally elastic coupling has a switching element that is arranged at least in part in a first elastomer of the elastomers. A method is provided for producing a first elastomer for a rotationally elastic coupling of this kind. A method is provided for identifying a wear state for a rotationally elastic coupling of this kind.

    摘要: A driving-side transmission portion of an output shaft of an electric motor and a driven-side transmission portion of a worm shaft are coupled to each other via a torque transmission joint including an elastic member and a coupling such that the torque can be transmitted. One axial end portion of a coupling-side concave-convex portion of the coupling is engaged with a first driving-side concave-convex portion of the driving-side transmission portion with a gap in the circumferential direction, and the other axial end portion thereof is engaged with a first driven-side concave-convex portion of the driven-side transmission portion with a gap in the circumferential direction. The elastic member is provided between an axial center portion of the coupling-side concave-convex portion, and a second driving-side concave-convex portion of the driving-side transmission portion and a second driven-side concave-convex portion of the driven-side transmission portion such that the torque can be transmitted respectively.

    摘要: A claw coupling includes two coupling elements having claws which engage alternately into one another and have confronting concave claw surfaces configured to follow a first circular track. Disposed between the coupling elements is a pressure body arrangement having pressure bodies respectively received between the claws of one coupling element and the claws of the other coupling element. The pressure bodies have convex pressure body surfaces which engage during a torque transmission with the claw surfaces of the claws. Each pressure body surface is configured to follow a second circular track, with the radius of the first circular track and the radius of the second circular track touching one another at a radially innermost point of the claw surface which is disposed on a common straight line having a center point of the first circular track and a center point of the second circular track.
