FIELD: process engineering.
SUBSTANCE: invention relates to suppression of vibrations in electrically driven hand-held machines. Proposed machine comprises drive, percussion mechanism generating vibrations along the line of its action and dynamic damper of said vibrations. Said dynamic damper comprises moving inertial element with degree of freedom that forms with percussion mechanism action line the angle other than zero and corresponds to crosswise displacement. Inertial element is fitted on dynamic damper axle inclined to percussion mechanism action line at the angle other than zero.
EFFECT: higher efficiency of damping.
