PROCEDURE FOR ASSEMBLED ROTOR BALANCING Russian patent published in 2014 - IPC G01M1/32 F04D29/66 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used for assembling and balancing of modular rotors of compressors of gas transfer units. According to the method of balancing of the modular rotor the shaft is balanced using the plains of correction unbalances at the ends of the shaft and its coupling and the assembled rotor is balanced, meanwhile the flapping of connecting flanges of couplings with reference to their balancing surfaces are measured, the places of the maximum radial flapping of flanges are determined and marked. Then the marked locations are mated and couplings are joined, the assembly is balanced first with correction of the main vector in the plain of the joint, and then with correction of the main moment of unbalances in plains located near balancing surfaces. After that, couplings are disjoined, the rotor is assembled with arranging of the marked locations in one plain, and it is balanced using the plains of correction of unbalances at the ends of the shaft.

EFFECT: invention is aimed at improvement of precision of rotor assembly.
