Claim Text:
1. A friction drive for force transmission, having a drive element, an output element, and a torque-limiting device acting between the drive element and output element, which torque-limiting device transmits a drive torque introduced by the drive element up to a transmission torque, which is set by means of the torque-limiting device, to the output element and generates free running for a drive torque which exceeds the set transmission torque, and which comprises at least one rolling bearing having an inner race and an outer race as well as rolling bodies arranged therebetween, as well as a clamping device that uses the inner race and the outer race of the at least one rolling bearing of the torque-limiting device that are displaceable towards one another in the axial direction or are clamped to each other in the radial direction for setting the transmission torque, wherein a torsional isolation device is provided between the clamping device and the torque-limiting device and the torsional isolation device is formed as a rolling bearing; wherein the rolling bearing of the torsional device is arranged to be axially displaceable by the clamping device with its inner ring; and wherein an annular gap is provided between the inner race of the at least one rolling bearing of the torque-limiting device and a shaft section of the drive element, at least two sealing elements which are arranged at a distance to each other being arranged in said annular gap.
