Abstract: Device for the balancing of rotors, comprising a chamber for a liquid balancing compound, the chamber containing electrodes connected to a pulse generator which is connected electrically with the output of a control unit whose input is connected to a transmitter which registers vibration parameters of the rotor while the latter rotates in supports in front of a nozzle in the chamber. At a moments when the "light" point on the surface of the rotor passes in front of the nozzle, the transmitter sends signals to the control unit and, responding to these signals, the pulse generator sends corresponding electric pulses to the electrodes in the chamber; the resultant electrohydraulic impacts discharge portions of the balancing compound through the nozzle onto the "light" point of the rotor.

Abstract: A rotor balancing apparatus comprises a chamber for balancing material, the chamber having a nozzle and being arranged in the field produced by an electromagnetic inductor coupled to a pulse generaor which, in turn, is electrically connected to the output of a control unit. The input of the control unit is connected to a transducer of vibration parameters of the rotor being balanced, as the latter rotates in front of the nozzle of the chamber. As electric pulses are applied to the inductor from the generator, magnetic pulse forces are generated in the chamber, whereby doses of the balancing material are ejected through the chamber's nozzle onto the surface of the rotor being balanced, which takes place at the moment when the "light" point area of the rotor is in front of said nozzle.
