METHOD OF CONTROL OF OPERATING FORCE (VERSIONS) AND REGULATED VIBRATOR FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC B06B1/16 

FIELD: machine building.

SUBSTANCE: group of the inventions includes the methods of control of operating force at excitation of vibration oscillations by rotating of two and more unbalanced masses by change of their mutual angular location, and unbalanced regulated vibration exciter. The offered method of control of operating force includes operations of excitation of vibration oscillations by rotating of two and more unbalanced masses, change of their mutual angular location. The named change is performed smoothly, by separate rotating drives by each unbalanced mass at continuous rotating or by combining of moves of two and more drives at continuous rotating. Meanwhile the maintaining of operating force at a constant level is possible at change of frequency of vibration and/or its change at constant frequency. During change of operating force at excitation of simple harmonic motions the unbalances composition is changed simultaneously. The offered unbalanced regulated vibration exciter includes a power shaft, with unbalance, and additional unbalance, installed with a possibility of change of angular position with reference to the first unbalance. The additional unbalance is installed on the additional shaft located axially with the first shaft and equipped with a drive. The shaft drive is made as the differential mechanism, one drive of which is connected to a spider and satellites, minimum amount is per amount of shafts. At least one satellite is connected to the shaft and with the motionless wheel, and at least one more satellite is connected to the respective shaft and movable wheel with own drive.

EFFECT: ensuring of smoothness and comprehensiveness of regulation of operating force in a wide frequency range of mechanical oscillations, including harmonic ones, without vibrating process interrupt.
