An adjusting device for a machine tool comprises a base body (), a movable body () movable along a moving direction (X) relative to the base body, and a drive () for moving the movable body relative to the base body. In order to effectively damp vibrations between the movable body and the base body (in particular so-called stray vibrations) and yet still enable rapid positioning movements of the movable body relative to the base body, the adjusting device comprises an auxiliary body () which can be releasably fixed to the base body and, in the released state, can be moved together with the movable body relative to the base body. The adjusting device also comprises at least one vibration damper () which is arranged between the auxiliary body and the movable body.

Adjusting device for a gear cutting machine with a reduced tendency to vibrate

The invention relates to an electrical machine having a rotor (), a stator () radially surrounding the rotor, and a housing () radially surrounding the stator. In order to minimize stresses in the housing and nonetheless decrease the tendency of the stator to torsional vibrations, the stator is connected to the housing at least at one end in a radially and torsionally rigid but axially movable manner, for example, by way of an axially compliant material area. The electrical machine can, in particular, be a motor spindle in a gear finishing machine.
