  • vibrations are generated in particular from a striking mechanism, which leads to a faster fatigue and to a reduction of holding forces of an operator. Vibrations transmitted from a machining location via the machining tool can amplify such vibrations. It is known to reduce such vibrations or vibrations, for example in the form of handles that are partially rubberized. A vibration damping achieved thereby is often only insufficient.

  • An axial preload can be produced via a screw connection or another connection between the housing part shells.
  • a design of the teeth is often critical.
