VIBRATION GENERATOR AND METHOD OF CONTROL OF ITS VIBRATIONS DIRECTION Russian patent published in 2009 - IPC B06B1/16 

FIELD: mechanics.

SUBSTANCE: invention refers to facilities for vibrational impact on oil pool from ground surface in order to increase output and it ensures precision control of phase and direction of vibrations of vibration generator in vertical and horizontal planes without use of mechanical drives for vibrators turn. Vibration generator contains a pair of coaxial load shafts with balance weights, mechanically independent drive of each shaft is as electric motor connected to shaft by coupling and provided with disk-carrier of code of noncontact sensor of rotation frequency and phase turn angle of balance weight, which sensing head is connected to synchronising system of vibration generator control. At that shafts with balance weights are arranged horizontally on vibrobench provided with vertical centerline with electric collector, noncontact sensor of turn angle and electrically controlled lock. Method of precision control of direction of vibrations of vibration generator in horizontal plane is implemented by the above device.

EFFECT: providing of precision control of vibrations direction in two perpendicular planes without use of additional mechanical drive.
