METHOD OF ADJUSTING VIBRATIONS AMPLITUDE DISTRIBUTION OF VIBRATING PROCESS BENCH WORKING ELEMENT AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC F16F15/04 

FIELD: machine building.

SUBSTANCE: group of inventions relates to the field of machine building. When correcting the distribution of oscillations amplitude of the working member, two vibration exciters are created by the flat oscillatory motion. Vibration exciters are installed on ends of working element. Two-type lever mechanisms are introduced on both sides of the working element. Length of lever mechanisms and rigidity of resilient elements are adjusted. Specified rigidity of the system is changed to achieve the required level of the working member amplitudes. Proposed device comprises working element furnished with two symmetrically arranged second-type lever mechanisms. Mechanisms of the second kind on free ends have additional bulkheads. Additional tails are configured to vary masses. Gear ratio ratios change the elastic element stiffness between the weight and the bearing surface by changing the arm lengths.

EFFECT: possibility of correcting distribution of amplitude of working member.
