  • Patent number: 10119574
    Abstract: A device for transmitting torque on an axis from a drive to an output has a first connection for connecting with the drive and having a vulcanization surface, and a second connection for connecting with the output and also having a vulcanization surface. An elastic element formed of rubber-elastic material is in the power transmission path between the two connections, is constructed so as to be radially soft, permitting a radial offset of up to 1 mm between the first connection and the second connection, is torsionally rigid to permit an only very small torsion angle of at most 1.5° between the first connection and the second connection, and is vulcanized to the vulcanization surface of the first connection and to the vulcanization surface of the second connection.

  • Patent number: 9759287
    Abstract: A coupling for transmitting torque from a drive to a load has a first connection for connection with the drive, a second connection for connection with the load, and an elastic element for vibration damping and between the first and second connections in the energy transmission path therebetween. An actuator carried on the elastic element has a base body and a centrifugal mass body rotatable relative thereto. One of the two bodies carries an electrical conductor and the other of the two bodies carries a permanent magnet. The conductor is in a magnetic field of the permanent magnet. Thus a flow of current through the conductor makes the centrifugal mass body exert an angular force on the base body to compensate for rotational vibrations.

  • Publication number: 20160138656
    Abstract: The invention relates inter alia to a device (10) for the transmission of torques from a drive (12) to an output (14), comprising a first connection (11), in particular a flange, for connection with the drive, and a second connection (13), in particular a hub, for connection with the output. The characteristic of the invention consists inter alia in that in the power transmission path between the two connections an elastic element (25) is arranged, which is constructed so as to be radially soft, permitting a radial offset between the first connection and the second connection, and so as to be torsionally rigid, permitting an only very small torsion angle between the first connection and the second connection.
