A method for stepwise balancing of disk-type compressor rotor

Abstract

The application belongs to the technical field of aero-engine assembly technology, and particularly relates to a method for step-by-step balancing of a disk compressor rotor. The method adopts a step-by-step balancing mode to perform static balancing adjustment or dynamic balancing adjustment on each component of the compressor rotor during installation. Compared with a traditional process scheme of directly performing dynamic balancing on the entire rotor, the method can effectively improve the force imbalance and force couple imbalance that may occur at each impeller installation section of the rotor, so that each order vibration amplitude of the rotor meets the requirements, and thus overcomes the rotor deflection deformation and engine vibration problems caused by local dynamic imbalance.
