Description

technical field

[0001] In particular, the invention relates to a balancing assembly, a rotor system, a gas turbine and a balancing method. Background technique

[0002] The axial-flow aeroengine is composed of high-pressure and low-pressure dual rotors, in which the low-pressure rotor is composed of a fan booster stage and a low-pressure turbine, and the high-pressure rotor is composed of a high-pressure compressor and a high-pressure turbine. The dual-rotor structure puts forward higher requirements for the balance process of the aero-engine. In the design and manufacturing process of the aero-engine, due to uneven material or blank defects, errors in processing and assembly, even the design is asymmetrical Due to various factors such as the geometric shape of the engine, when the engine is running normally, the centrifugal inertial forces of the rotating parts cannot cancel each other out, and act on other parts through the bearings, causing vibration and noise, which acce...
