Embodiment 1

[0014] refer to figure 1 , the embodiment of the present invention proposes a vane crank-slider mechanism for a turbine compressor, including: a housing 1, a vane 2, a crank 3, a pin 4, a slider 5 and an adjusting cylinder 6; Mounting holes are provided in the radial direction, and one end of the vane 2 is provided with a shaft handle 201. The shaft shaft 201 protrudes out of the housing 1 through the mounting hole. One end of the crank 3 is fixedly connected to the shaft handle 201 laterally, and the other end A pin shaft 4 is arranged laterally, and a slide block 5 is arranged to rotate on the pin shaft 4. The adjustment cylinder 6 surrounds the outside of the housing 1, and an annular groove 601 is arranged inside the adjustment cylinder 6, and the slide block 5 is slidably fitted in the ring groove 601. Among them, both sides of the slider 5 are slidingly matched with both sides of the annular groove 601, wherein the material of the slider 5 is a carbon-metal composite mat...

Embodiment 2

[0017] refer to figure 1 , On the basis of Embodiment 1, a through hole 501 is provided in the middle of the slider 5 , and the pin shaft 4 is rotatably matched with the inner side wall of the through hole 501 .

[0018] The pin shaft 4 is made of 35# steel material. Since the slider 5 is made of carbon-metal composite material, it has the characteristics of compression resistance, wear resistance, high temperature resistance and self-lubrication, and can be directly rotated with the pin shaft 4 through the through hole 501. No additional bearing pads or wear sleeves are required.

Embodiment 3

[0020] refer to figure 1 , On the basis of Embodiment 1, the end of the pin shaft 4 passing through the through hole 501 is provided with a washer 7 .

[0021] The groove bottom of annular groove 601 is arc-shaped, and one end of bearing pin 4 passing through the through hole 501 of slider 5 is fixed with gasket 7, and gasket 7 separates slider 5 from the groove bottom of annular groove 601 to avoid slipping. The block 5 is in contact with the bottom of the annular groove 601 .

Abstract

The invention proposes a stator vane crank slider mechanism for a turbine compressor. The stator vane crank slider mechanism comprises a shell, a stator vane, a crank, a pin shaft, a slider and an adjusting cylinder; a mounting hole is arranged on the shell in a radial direction; one end of the stator vane is provided with a mandrel; the mandrel passes through the mounting hole and extends out ofthe shell; one end of the crank is fixedly connected with the stator vane in a lateral direction; the other end of the crank is provided with the pin shaft in the lateral direction; the pin shaft is rotatably provided with the slider; the adjusting cylinder is enclosed on the outer side of the shell; an annular groove is arranged at the inner side of the adjusting cylinder; the slider is slidablyassembled in the annular groove; and the two sides of the slider are in sliding fit with the two sides of the annular groove, wherein the material of the slider is a carbon-metal composite material. The stator vane crank slider mechanism for the turbine compressor provided by the invention is simple and compact in structure, convenient to install, simplifies the mechanism and improves the workingperformance of the mechanism.

Description

technical field [0001] The invention belongs to the technical field of turbocompressors, and in particular relates to a vane crank slider mechanism for a turbocompressor. Background technique [0002] The turbo compressor unit is a dynamic compressor with high-speed rotating impellers, which is widely used in the corresponding process of transporting various gases, and can increase the pressure of the gases. Among them, the axial flow turbine unit relies on adjusting the angle of the vane to adjust the flow of air entering the fan to meet the requirements of different working conditions. In order to meet the conditions of use, automatic, flexible and rapid adjustment of the vane is required. However, the structure of the conventional vane angle adjustment mechanism is complicated, the process is complicated, the installation is very inconvenient, time-consuming and labor-intensive, and it is not suitable for high-temperature conditions. Contents of the invention [0003] ...
