The invention relates to a hand-held electric power tool comprising at least one driven rotating part () that is mounted in at least one bearing (). According to the invention, the rotating part () is vibrationally decoupled from the bearing ().

Electric hand-held power tool

An eccentric transmission having an imbalance compensation element (-) and having an eccentric element (-) for converting a revolving rotary motion of an armature shaft (-) into an oscillating rotary motion of a drive shaft (-) in order to drive an insert tool (-) of a hand-held power tool (-) to oscillate. The imbalance compensation element (-) is integral to another functional unit (-).

Eccentric transmission with an imbalance

A machine tool and a tool include an automatic balancing device, with a first balancing mass located such that it is movable relative to the shaft of the machine tool in all radial directions and in the circumferential direction, that may be started rotating via the rotation of the shaft, and that, during rotation, exerts a force on the shaft in the radial direction.

Machine tool and tool, both with an automatic balancing device

A hand held power tool has a housing, a drive, a mechanical striking mechanism with a striker, a drive element for driving the striker in its striking movement and having at least one curved track with raised and depressed portions, and a sensing element in operative connection with the striker supported on the drive and having a sensing member bringable in operative position with the raised and depressed portions of the curved track.
