ROTOR BALANCING METHOD Russian patent published in 2015 - IPC G01M1/00 

FIELD: machine building.

SUBSTANCE: unbalance is measured, correction action parameters are determined for each correction plane, and weights are corrected, parameters of the correction actions complying with requirement for equality to zero of the residual unbalances in specified correction planes. Then the rotor corrections are determined considering shift of the corrected weight centres from the rated radiuses and planes using simulation of the expected consequences of corrections, then rotor weight is corrected. At that the virtual 3D image of the rotor balance is created, on the virtual rotor the static and instantaneous unbalances are simulated before shift of the main central axis of inertia with axis of rotation. The unbalance parameters are specified, weights are corrected on the virtual reference rotor sample, and virtual correction of the rotor is monitored in the correction planes, and database of the virtual rotor samples is created. Then the balanced rotor is installed in the machine, dynamic pressure is measured in its unbalance supports, unbalances are coincided and compared, and by deviation value the necessity of the rotor balance is determined after deletion of the correcting weight, and as per the minimum residual unbalance of the rotor the balance quality is determined.

EFFECT: increased accuracy of the rotor balancing.
