FIELD: vibration equipment.
SUBSTANCE: invention relates to vibration equipment, namely to electromechanical centrifugal vibration exciter of resonant oscillations used in mining, construction, chemical, food and other industries. Centrifugal vibration exciter of resonant oscillations consists of a drive, on shaft ends of which unbalances with additional axes of rotation are fixed, on which unbalanced masses are installed so that unbalanced masses remained stationary relative to their rotation axes during rotation of unbalances around horizontal axis of vibration exciter shaft and occupied natural positions under action of gravity.
EFFECT: technical result consists in the possibility of creating both superharmonic and subharmonic resonant oscillations in vibration machines with non-linear characteristic of elastic elements depending on for which resonance oscillations this vibration system is tuned.
