Abstract
A vibration exciter is provided. The vibration exciter includes a shaft and at least two unbalanced weights arranged on the shaft, in which the radial distance of the common center of gravity of the unbalanced weights from the rotational axis of the shaft is adjustable in an infinitely variable way by means of a gear. The vibration exciter comprises a gear which is a spatial coupling gear, e.g. a spatial vibration slider gear. A simple and compact configuration of the vibration exciter is thus proposed, in which the required adjusting forces for changing the imbalance are very low.
