Patent abstract
A device for damping vibrations in a drive train, in particular for plug screws in the pulp and paper industries. The device is principally characterized in that a cylindrical shaft, preferably designed as a hollow shaft, is provided, wherein the cylindrical shaft is arranged between the halves of a coupling and at least one ring having friction surfaces is arranged around the cylindrical shaft. Stick-slip vibrations that occur can thereby be favorably eliminated, and thus the gearbox and the motor of the drive train can be protected.
