FIELD: process engineering.
SUBSTANCE: invention relates to percussion-type tools. This tool comprises dynamic vibration damper and vibrator. The latter is driven by the motor to make dynamic damper work by application of external forced thereto. Said damper comprises weight linearly displacing in axial direction of the hammer and resilient element to apply shifting force to said weight in axial direction of said hammer. Vibrator comprises camshaft driven by said motor, off-centred cam and two pins. At least one camshaft axial end runs in the bearing. Pins are linearly driven by off-centred cam for actuation of dynamic damper. One of said pins abutting on off-centred cam is fitted in bearing housing across camshaft axis.
EFFECT: easier assembly.
