BALANCING OF ROTORS OF COMPRESSORS AND TURBINES WITH INCOINCIDENT WORKING AND BALANCING SURFACES

S.M. Beloborodov, I.V. Shibanov

The analysis of the reasons of occurrence of a disbalance of rotors of compressors and turbines aviation engines and industrial GTU is resulted. The disbalance which principal cause is eccentricity a balancing axis concerning an axis of rotation of a rotor, can exceed admissible values on usages. The balancing methods one of which consist in preliminary measurement warp a shaft in planes of correction concerning landing surfaces under bearings with the subsequent balancing by means of removal of metal and installation imitating mass the set weight are offered, and another is based on a method of calculation mutual centering error axes.

Key words: balancing, disbalance, rotor, imitating method, turbine, vibration level.
