BALANCING METHOD OF ASSEMBLED ROTOR Russian patent published in 2009 - IPC G01M1/32 F04D29/66 

FIELD: mechanical engineering.

SUBSTANCE: balancing method of assembled rotor is that it is balanced shaft and successively, after installation on shaft of regular component it is balanced assembled rotor. Additionally balanced rotor is fixed to flanges of motor shafts and compressor and it is implemented correction of assembly imbalance, for that there are measured values of maximal radial runout of balancing surfaces of rotor. There are marked places of zero radial runout of balancing surfaces of rotor. On surfaces of rotor in correction planes there are installed flyweights from the side zero radial runout of balancing surfaces. Mass of correcting flyweights are defined by formula depending on parts mass of assembled rotor, corrected in particular planes, values of beatings of closest to the correction plane balancing surface, installation radius of flyweight.

EFFECT: application of method iteratively reduces imbalance of rotor, provided by concentricity of its installation, increases operation resort of aggregate, reduces cost of balancing and commissioning, increases accuracy of mounting and productivity of labour.
