Embodiment Construction

[0017] Depend on figure 1 It can be seen that the gas turbine (1) is composed of a compressor, a combustion chamber and a turbine, and the power generated by the turbine is used to drive a generator or other working machines except for driving the compressor, wherein the compressor casing, the combustion chamber and the turbine The casing (2) is stationary on the gas turbine, while the compressor and turbine rotating parts consist of several disks, shafts and blades, arranged on a common rotor part (3), all parts of the rotor are Rotate at high speed around the rotor axis of rotation.

[0018] There are shafts (4) at the front and rear ends of the rotor of the gas turbine, and the rotor is supported on the stationary casing of the gas turbine through radial sliding bearings (6) and bearing casings (5) on the front and rear shafts to transmit the rotor mass force and rotational unbalance Force to the stationary receiver.

[0019] A thrust disc (9) is fixed on the front shaft ...

Abstract

The tiltable bush-spring sheet assembly for gas turbine has separated main bush and auxiliary bush supported onto the spring sheet assembly tiltably. The spring sheet assembly comprising several laminated spring sheets is used to balance the loads on different bushes caused by their tilt and unevenness. Via measuring the rigidity of each spring sheet, the rigidity of the laminated spring sheet assembly is calculated. During trial or running of the gas turbine, the spring sheet assembly is forced to deform, and measuring the axial displacement of the rotor can measure the axial force of therotor.

Description

Technical field [0001] The invention relates to a tilting shoe spring leaf assembly for transferring aerodynamic axial force on a rotor in a gas turbine composed of a compressor, a combustion chamber and a turbine part. The compressor and turbine components of a gas turbine have a stationary casing and blades to form a stator, and a high-speed rotating compressor, a turbine disk and a rotor to form blades. The rotor is supported on radial sliding bearings, and the aerodynamic axial force on the rotor is transmitted to the static block-type main and auxiliary tilting pad bearings through the rotating thrust plate and then transmitted to the elastic assembly on the stator casing of the gas turbine. Background technique [0002] Gas turbines not only have the characteristics of high cycle efficiency and convenient operation, but also need to quickly adapt to load changes. Therefore, it has been widely used in power generation, natural gas transmission booster station, chemical...
