Abstract
A vibration generator has at least two shaft groups, on which at least two imbalance groups are disposed, and which are connected with at least one drive by means of which they are put into rotation. The shaft groups are connected with the at least one drive so that the speed of rotation of one shaft group amounts to a multiple of at least one other shaft group, and the shaft groups demonstrate a significantly different static moment with regard to one another. At least one of the shaft groups is connected with a phase shifter, by way of which the static moment of the shaft group can be adjusted.
