Problems solved by technology

Balance weights / balance screws used for counterweights are all of a similar structural design, changing the height, length or thickness of the weight / balance screw by increasing or decreasing a dimension on a feature, and thus changing its weight, requires Due to repeated disassembly and replacement, sometimes the required balance cannot be achieved. At the same time, on-site grinding of the balance weight / balance screw is required, which greatly affects the balance efficiency.

Abstract

The invention relates to a gas turbine, a rotor system and a balancing assembly and a balancing method for balancing the rotor system. The balance assembly comprises a balance screw used for being connected with an air inlet cone rear supporting ring of the rotor system in the circumferential direction, the balance screw is provided with a groove extending from the head end of the balance screw tothe tail end of the balance screw, the groove comprises a groove head and a groove body extending from the groove head, and a first mass balance piece is contained in the groove body.

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...
