Embodiment
[0031] The existing support devices for gas turbines meet the requirements of stable work, but the heat deformation and uneven force deformation encountered during the working process are inevitable, but the existing support devices lack corresponding treatment for the above two deformations structure, then, the accumulated deformation after long-term use will make it difficult for the support device to achieve the function of stable operation, affect the normal operation of the gas turbine, and even cause damage and destruction to the gas turbine.
[0032] Therefore, a support device that can cope with the above two deformations is proposed here, specifically, as figure 1 As shown, a gas turbine double-layer power transmission device includes a first part 1, a second part 2 and a third part 3, wherein the second part 2 includes an upper part and a lower part, and the upper part and the first part 1 form a "Z" structure, the lower part and the third part 3 form a "person" stru...

The invention discloses a gas turbine double-layer force transmission device, the gas turbine double-layer force transmission device comprises a first part, a second part and a third part, the second part comprises an upper part and a lower part, the upper part and the first part form a Z-shaped structure, and the lower part and the third part form a herringbone structure; the two sides of the Z-shaped structure are each provided with a baffle, the first part, the second part and the baffles define an air guiding cavity, correspondingly, an air guiding hole communicated with the air guiding cavity is formed in the upper portion, and an air outlet communicated with the air guiding cavity is formed in the first part. According to the double-layer force transmission device of the gas turbine, a Z-shaped structure and a herringbone structure are sequentially formed from top to bottom, the acting direction of acting force is adjusted, transmission of the acting force is more uniform, and deformation caused by uneven stress is reduced. Through mutual cooperation of the Z-shaped structure and the baffle, heat is guided to be discharged, a temperature buffer area is formed, thermal deformation is reduced, and damage caused by thermal deformation is reduced.
Description
technical field [0001] The invention belongs to the technical field of force transmission structures, and in particular relates to a double-layer force transmission device for a gas turbine. Background technique [0002] The compressor is a part of the gas turbine engine that uses high-speed rotating blades to do work on the air to increase the air pressure. The front end of the blades of the compressor impeller is curved and is called a guide wheel. Its function is to introduce the gas without impact The working impeller reduces the impact loss of air flow. There is a diffuser at the outlet of the impeller of the compressor, so that the kinetic energy obtained by the gas in the impeller can be converted into pressure as much as possible. [0003] The gas turbine compressor works under the condition of high-speed rotation, so the intermediate support device generally used at the connection between the high-pressure compressor and the low-pressure compressor plays a vital ro...
