Stator blade and inner ring supporting mechanism

Abstract

A stator blade and inner ring support mechanism is described that includes a stator blade, an inner ring, and an elastic structure located between the stator blade and the inner ring, the upper portion of the elastic structure abutting below the stator blade, and the lower portion of the elastic structure abutting above the inner ring. When the elastic structure is installed on the inner ring but not provided with the stator blade, the elastic structure can freely slide in the groove of the inner ring in the circumferential direction of the inner ring, and the height of the elastic structure in the free state is larger than the gap between the stator blade and the inner ring. After the stator blade is installed on the inner ring, the elastic structure is compressed, so that the elastic structure generates acting force between the stator blade and the inner ring, and under the condition that a gap exists between the stator blade and the inner ring, the stator blade and the inner ring supporting mechanism can not only play a role in supporting the inner ring, but also play a role in supporting the inner ring. And the radial positions of the inner ring and the honeycomb can be ensured to be consistent, so that the honeycomb and the labyrinth of the rotor are structurally matched with each other to obtain a better sealing effect.

Description

technical field [0001] The invention relates to the technical field of aero-engines, in particular to the technical field of gas turbines and other turbine-impeller rotating machines, and more particularly to a stator blade and inner ring support mechanism that can be applied to gas turbines and other turbine-impeller rotating machines. Background technique [0002] A gas turbine is an internal combustion power machine that uses a continuous flow of gas as a working medium to drive the impeller to rotate at a high speed, thereby converting the energy of the fuel into useful work. The air is sucked in by the outside atmospheric environment, and is compressed by the axial flow compressor to pressurize it step by step, and the air temperature is also increased accordingly; the compressed air is pressed to the combustion chamber and mixed with the injected fuel to generate high temperature and high pressure gas; then Then enter the turbine to expand and do work, and push the tur...

However, this prior literature does not refer to any elastic structures

[0013] Obviously, above-mentioned existing literature all can't effectively solve the technical difficult problem existing at present
