METHOD OF ROTOR ASSEMBLY BALANCING Russian patent published in 2015 - IPC F04D29/66 G01M1/32 

FIELD: machine building.

SUBSTANCE: invention refers to machine building and can be used at mounting of rotor assemblies of gas compressor units. When a rotor is assembled, a shaft and all its elements are balanced, the assembled rotor is balanced and fixed to the shafts of a motor and a compressor, mounting disbalances are corrected by weight units, their weight is determined on the basis of the weights of the rotor assembly parts whose disbalances are corrected in these planes, the values of balancing rotor surfaces' beating and the distance from the point of the weight unit installation to the rotation axis. Four points are chosen and marked on every control rotor surface, they are arranged pairwise diametrally oppositely in mutually perpendicular planes. Radial beating of control surfaces is measured in the marked points in respect to the zero point after rotor balancing and after the balanced rotor is attached to the shafts of the motor and compressor. The results of both measurements are recorded, the weight units are mounted on the prepared points in the measurement planes, the weight and points for the weight units are determined on the basis of the proposed dependencies.

EFFECT: invention is aimed at improving the rotor assembly balancing accuracy due to the minimisation of local mounting disbalances determined by the eccentricity of installation.
