FIELD: machine building.
SUBSTANCE: procedure consists in balancing vane rotor on balancing machine, first with aerodynamic balancing, and further with mass balancing. Also, aerodynamic balancing is performed successively with rotations twice less, than rotations of mass balancing, and further with rotations of mass balancing with record of values and angular positions of vector unbalances. Further, there are determined vanes creating aerodynamic unbalance. Their ends are improved to eliminate unbalance with alternate control for aerodynamic unbalance, whereupon mass is balanced.
EFFECT: more efficient reduction of vibration of vane rotors.
