Abstract
A vibration generator comprises two unbalance shafts, which are positively coupled in a contra-rotative manner and whose relative phrase position can be shifted by a phase shifting device. Each of the unbalance shafts supports a main unbalance mass and a partial unbalance mass that can move in relation thereto. The position of the partial unbalance masses on the respective unbalance shafts can be actively altered within a large range by adjusting devices. The resulting vibration vector generated by the vibration generator can set in a diverse manner with regard to direction and magnitude.
