FIELD: electricity.
SUBSTANCE: device includes vibration exciter and elastic elements. As per the first version, stable angular oscillations of yoke with working piece, which is rigidly connected to shaft of oscillation exciter, are provided with passive magnetic suspensions made as system of constant magnets operating as per differential circuit in mode of repulsive powers, and elements to control the distance between magnets. As per the other version, excitation of yoke oscillations with working piece is performed with active magnetic suspension consisting of motor, constant magnet fixed on end part of motor shaft rotating at specified speed and direction, and magnet rigidly connected to yoke. Passive magnetic suspensions made as system of constant magnets operating as per differential circuit in mode of repulsive powers, and elements to control the distance between magnets, are used as elastic elements. Working piece is brought into additional movement with the second oscillation exciter.
EFFECT: invention provides the creation of the device with adjusted position of stable balance of shaft of oscillation exciter and increase of amplitude and frequency of oscillations of working piece; improves reliability, service life of etching device, efficiency and quality of its operation.
