ROTOR BALANCING METHOD IN ONE CORRECTION PLANE Russian patent published in 2013 - IPC G01M1/16 

FIELD: machine building.

SUBSTANCE: rotor is installed in supports of balancing stand. There are two correction planes on rotor butt-ends, one of the planes is balancing and the other is testing. The rotor has specified maximum allowable asymmetry parameters - values of transverse displacement of masses centre and displacement angle of longitudinal principal axis of inertia at centre of gravity relative to its geometric axis. Rotor rotation is started, during rotation at first amplitudes and phases of vibration of both supports, induced by initial imbalances of rotor, are determined. Then, attaching test weights to each correction planes in sequence, amplitudes and phases of vibration of both supports are determined again. Then by the obtained results coefficients of balancing sensibility of the stand and coefficients of impact of correction planes are calculated. Then determined are values and angles of initial imbalances in each correction plane, used for determination of initial values of parameters of mass-inertial asymmetry. If at least one of these values exceeds specified admissible limit value, balancing imbalance is created in balancing correction plane. For its creation at first modelled is imbalance in balancing correction plane providing exclusion of initial imbalance in this correction plane, and then, considering coefficients of impact of correction planes, modelled is imbalance in balancing correction plane providing values of parameters of mass-inertial asymmetry not exceeding corresponding specified admissible limit values.

EFFECT: possibility of optimisation of parameters of mass-inertial asymmetry, improving accuracy of residual parameters of imbalance determination and reduction of labour intensity of balancing process.
