FIELD: process engineering.
SUBSTANCE: invention relates to manual machines with dynamic damper. Hand-held machine comprises percussion axle, idle shaft parallel with said axle, first oscillator and second oscillator. First oscillator drives the percussion mechanism and is fitted on idle shaft and comprises oscillating element. Second oscillator drives the dynamic vibrosignal and includes second oscillating element. Phase shift Δ, other than zero, is provided for between first oscillating element motion and second oscillating element. Phase shift Δ is not equal to 180°.
EFFECT: better damping.
