FIELD: mechanical engineering. SUBSTANCE: vibration suppressor has two vibration exciters of directed action, each having a pair of like unbalanced rotors connected with their gears and driven by their own electric engine. Setting of vibration suppressing force is effectuated by system, which selects rotation phases of unbalanced rotors creating suppression and excitation forces of equal value and opposite directions. EFFECT: increased efficiency in protecting machines, instruments and other objects from vibration effects including vibrations developed within objects, simplified construction and enhanced reliability in operation. 24 cl, 1 dwg |
