Embodiment 1

[0023] Such as Figure 1 to Figure 4 As shown, a gas turbine includes a first transmission shaft 1 , a second transmission shaft 2 , a flexible coupling 3 , a compressor stator 4 and an exhaust volute 6 .

[0024] In the present invention, since the power turbine shaft of the gas turbine is required to output power at the cold end and the hot end of the shaft at the same time, due to the influence of different temperatures, the power turbine shaft of the gas turbine will be deformed, and the position relative to the compressor stator will change, so that the load will be affected . In order to eliminate the impact of the power turbine shaft of the gas turbine on the load due to temperature deformation, the first transmission shaft 1 and the second transmission shaft 2 are connected by a flexible coupling 3 .

[0025] The advantage of the flexible coupling 3 is that the flexible coupling 3 has lower requirements on the installation accuracy of the connected first transmission ...

Embodiment 2

[0049] The second embodiment is basically the same as the above-mentioned first embodiment, the difference is that the connection plate 32 on the flexible coupling 3 is connected to the first transmission shaft 1 or the second transmission shaft 2 without a key, and the connection plate 32 The sleeve 321 of the sleeve 321 is hollow and is set as a light hole. The ends of the first transmission shaft 1 and the second transmission shaft 2 that are used to connect with the connecting disc 32 are all set as an optical axis. The light hole of the sleeve 321 is connected to the first transmission shaft. 1 or the optical axis of the second transmission shaft 2 are connected by expansion sleeves.

[0050] The advantage of adopting the keyless connection is that the processing is simple and the installation is convenient. Since there is no keyway on the shaft, under the condition of the same shaft diameter, the first transmission shaft 1 and the second transmission shaft 2 can carry a l...

Abstract

The invention discloses a gas turbine and relates to the technical field of gas turbines. The gas turbine comprises a first transmission shaft (1), a second transmission shaft (2), a flexible coupler (3), a gas compressor stator (4) and an exhaust volute (6), wherein one end of the first transmission shaft (1) is connected with one end of the flexible coupler (3), the other end of the first transmission shaft (1) is used for being connected with a load, and the middle of the first transmission shaft (1) is connected with the gas compressor stator (4); one end of the second transmission shaft (2) is connected with the other end of the flexible coupler (3), the other end of the second transmission shaft (2) is used for being connected with a load, and the middle of the second transmission shaft (2) is connected with the exhaust volute (6). The gas turbine has the beneficial effect that due to the fact that a power turbine shaft of the gas turbine is provided with two output ends, the requirement of a power turbine of the gas turbine for outputting torque at the gas compressor stator end and the exhaust volute at the same time is met.

Description

technical field [0001] The invention relates to the technical field of gas turbines, in particular to a gas turbine. Background technique [0002] In existing gas turbines, the power turbine shaft is an output structure at one end, and the output end is located in front of the compressor (cold end) or near the exhaust volute (hot end). The design of a certain type of gas turbine requires simultaneous output power at the cold end and the hot end , while the existing power turbine shaft structure is a single output, which cannot meet the requirements of simultaneous output torque at the cold end and the hot end. It is necessary to design a new structure so that the power turbine can output power at the cold end and the hot end at the same time. Contents of the invention [0003] The purpose of the present invention is to provide a gas turbine to solve the problem in the background art that the power turbine shaft of the existing gas turbine cannot output power at the cold en...
