HAND-DRIVEN MACHINE WITH DYNAMIC VIBRATION DAMPER

摘要

FIELD: machine building.;SUBSTANCE: invention relates to a hand-driven machine. The hand-driven machine includes a drive, a pusher, a holder for an operating tool related to the pusher and a counterbalance related to the drive for compensation of forces determined with the specified back-and-forth movement of the pusher. The drive has the possibility of transmitting to the pusher of back-and-forth movement along the translation movement axis. The counterbalance is installed with the possibility of back-and-forth movement along the translational movement axis and is kinematically connected to a guide cam made in a rotation body. A rotation axis of the rotation body coincides with the translational movement axis. Besides, at rotation of the rotation body, the counterbalance performs back-and-forth oscillatory movement.;EFFECT: increasing the vibration damping efficiency.;7 cl, 2 dwg
