Drive for rotating part of printer has motor locally variable by servo drive in direction with component parallel to rotary axis of rotating part

摘要

The rotating part (1) is driven by a motor (9) which is locally variable by a servo drive (12). In the engaged state the first coupling (6) can be compressed and strained in the axial direction of the rotating part. The journal (2) of the rotating part and the axis (8) of the motor are connected together as regards movement with at least one component parallel to a rotational axis of the rotating part by means of a second coupling which compensates any angular deviations. Independent claim describes method of separating drive from rotating part in that first the coupling is released by remote control and then the motor is moved linearly by a servo drive in a direction with at least one component parallel to the rotational axis of rotating part.
