FIELD: reclamation of worn-out parts of machines by methods of deposition of coats by pulse electric discharges. SUBSTANCE: gear has vibration head 1 of vertical movement flexibly coupled to counterweight 5, spindle made fast to armature of electromagnet and suspended from four similar cylindrical springs of right-hand and left-hand coiling placed horizontally, planetary differential gear train, toothed rack 27, source of power supply of electrode circuit and electromagnet. With build-up of worn-out surfaces of parts of machines with the use of material of bar electrode vibration head lowers smoothly. Differential gear train enables compression of spring to be diminished and by this resonance mode of operation of vibrator to be automatically ensured to keep frequency of inherent oscillations equal to frequency of disturbing current. EFFECT: increased functional efficiency and reliability of gear. 6 dwg
