Torque-transmitting coupling

A device for the transmission of torque from a drive to an output, the device comprising:

• a first connection for connecting with the drive,
• a second connection for connecting with the output, the device being constructed so as to be substantially torsionally rigid to permit only a very small torsion angle of at most 1.5° between the first and second connections, and
• an elastic and circular ring disk of rubber-elastic material in the power transmission path between the two connections and constructed in the manner of a rubber track and having a radial dimension more than twice as great as its axial dimension so as to permit an offset radially of the axis of up to 1 mm between the first and second connections while being torsionally rigid to permit an only very small torsion angle of at most 1.5° between the first and second connections.

A modular system for torsionally rigid couplings permitting offset radially of a rotation axis of the system, the system comprising:

• a first device with a first connection in the form of a ring flange with dimensions of a first type and with a second connection in the form of a first hub, wherein the device is constructed so as to be substantially torsionally rigid to permit only a very small torsion angle of at most 1.5° between the first and second connections and radially soft to permit a radial offset to of up to 1 mm relative to the axis, there is in the power transmission path between the two connections an elastic element formed as a rubber track with a radial dimension more than twice as great as its axial dimension, and
• a second device with a first connection in the form of a ring flange with dimensions of a second type, differing from the dimensions of the first type, and with a second connection in the form of a second hub the same dimensions as the first hub, the second device has between the respective first and second connections an elastic element that is substantially torsionally rigid and radially soft like the first connection and formed as a rubber track with a radial dimension more than twice as great as its axial dimension.
