VIBRATION DEVICE FOR CREATION OF BIHARMONIC MODES OF OSCILLATIONS

摘要

FIELD: machine building.;SUBSTANCE: using the proposed technical solution makes it possible to provide for solving of process tasks on reduction of hazardous dynamic loads at environment (structure, nature, service personnel). The vibration device comprises four parallel installed eccentric shafts that rotate in bearings, and on the tails of the shafts there are imbalances installed. The shafts connected to each other by means of geared wheels form a kinematic chain. A torque is applied to one of the shafts with the possibility to change the rotation frequency. On eccentrics of two adjacent shafts there are connecting rods of a lever-hinge suspension of the working element, which comprises a control beam and a lever of the working organ.;EFFECT: complete balancing of dynamic loads on the first and second harmonics of all structural parts of a vibratory machine moving in periodical mode.;2 dwg
