Regulator for a vibrations generator with unbalanced masses

Abstract

Abstract Vibrating elements (10 and 12) of an unbalanced mass vibration generator can be driven by means of controllable drive means (18, 20). Means (26) which have an integrating effect react to the differential of the speeds of rotation omega 1 to omega 2 of the unbalanced waves (14, 16) and integrate the latter to form an output variable @ which corresponds to the relative phase position of the two unbalanced waves (14, 16). The drive means (18, 20) can be driven by this output variable @ on a return path (32) via a power distributor with the effect of a negative feedback in order to restore the identity of speeds of rotation. In the return path there is an actuating device (36) by means of which the output variable @ can be additively acted upon with an actuating signal DELTA @. Thus, using little actuating force the centrifugal force resulting in a circulatory vibrator or the vibration direction in a directional vibrator can be adjusted. <IMAGE>
