Abstract (en)
[origin: WO9958258A1] The invention relates to a regulating device for an unbalanced mass vibration generator, comprising at least two pairs of partial unbalanced mass bodies that can be driven around an allocated axis whose vectorially added partial centrifugal force vectors form the resulting centrifugal force vector. Adjustment is carried out between a resulting minimal unbalance moment (amplitude of oscillation = minimal) and a resulting maximal unbalance moment (amplitude of oscillation = maximal) without any intermediate positions, whereby both allocated limiting phase angles are regulated using two stops. The regulating device also enables acceleration and stopping of the vibrator with a regulated minimal unbalance moment. The regulating device selectively utilizes one or two drive motors for regulating the phase angle. Due to the utilization of stops in adjusting the phase angle, it is no longer necessary to use complicated control means and a compact structure is made possible. The invention is preferably used in construction and construction material machines.
