Abstract

The invention relates to a driving device, in particular a screw foundation driving device, having an anchor with a rotational axis for receiving a driving tool, an outer rotor, which is arranged concentrically to the rotational axis of the anchor and can be rotationally driven by a motor, and an impact device from which an impact energy can be introduced into the anchor. By means of rolling bodies arranged circumferentially on the anchor, the anchor is mounted in the outer rotor in such a way that a relative movement between the anchor and the outer rotor can be executed in the direction of the rotational axis and a torque about the rotational axis can be introduced from the outer rotor to the anchor via the rolling bearings.
