Abstract
A vibration exciter for a soil compacting device includes a first unbalanced shaft on which at least one first unbalanced mass is arranged, a second unbalanced shaft which is arranged axially parallel to the first unbalanced shaft, which is contra-directionally rotatably coupled to the first unbalanced shaft in form-locked manner, and on which at least one second unbalanced mass is arranged, and a drive device for rotatably driving one of the unbalanced shafts and a rotation device. The drive device can be actuated by an actuation device in order to rotate the second unbalanced mass relative to the first unbalanced mass. The second unbalanced shaft has a cavity, and the actuation device is at least partially arranged inside the cavity.
