Abstract
A gear stage assembly having a gear stage with two meshing gearwheels for mechanically transmitting a torque includes individual magnets arranged in the form of a ring on each of the gearwheels in a manner corresponding to that of the teeth of the gearwheels, for producing magnetic forces in the gear stage, individual magnets of respective ones of the magnets formed in a ring being arranged with alternating polarity in the direction of rotation and forming a stage of magnets in a ring disposed parallel to the gear stage, for producing a preload torque in the gear stage; and a varnishing unit including the gear stage assembly.
