US 9,759,287 B2 · Torque-transmitting coupling

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.

Dependent claims

A device for transmitting torque from a drive to a load, the device comprising:

a first connection for connection with the drive;
a second connection for connection with the load;
at least one elastic element for vibration damping and between the two connections in the energy transmission path;
an actuator element associated with the elastic element and having at least one base body and a centrifugal mass body rotatable relative thereto;
at least one conductor section on one of the two bodies;
and
at least one permanent magnet on the other of the two bodies, the conductor section being positionable in the magnetic field such that, when current flows through the conductor section, the base body is able to be acted upon by an angular momentum generated by the centrifugal mass body in the sense of a compensation of rotational vibrations.
