Problems solved by technology

[0002] With the development of science and the progress of society, the country has been promoting the development of advanced technology. Among them, there has always been a relatively difficult technical problem in the field of turbine technology. The general turbine has the problem of cooling the turbine shaft, and the oil cooling method is often used. However, only relying on the limited cooling of the engine oil cannot completely cool the shaft, which will cause excessive heat generation and affect the efficiency and service life. The main purpose is lubrication. The device of the present invention solves this problem

Abstract

The invention discloses a turbine shaft. The turbine shaft comprises a machine body and a first cavity formed in the machine body, symmetrical second cavities are formed in the left end and the rightend of the first cavity, a third cavity is formed in the right end of the right-end second cavity, the turbine shaft extending left and right is in rotational fit in the first cavity, the left end andthe right end of the turbine shaft extend into the second cavities, a cooling flow oil hole with an opening formed leftwards penetrates through the turbine shaft, fixed blocks which are in rotationalfit with the turbine shaft are fixedly connected in the second cavities, bearings which are in rotational fit with the turbine shaft are arranged in the inner walls between the first cavity and the second cavities, oil sealing rings are arranged at the portions, close to the first cavity ends, of the bearings, and protruding parts located on the fixed blocks and close to the first cavity end arearranged on the turbine shaft.

Description

technical field [0001] The invention relates to the technical field of turbines, in particular to a turbine shaft. Background technique [0002] With the development of science and the progress of society, the country has been promoting the development of advanced technology. Among them, there has always been a relatively difficult technical problem in the field of turbine technology. The general turbine has the problem of cooling the turbine shaft, and the oil cooling method is often used. However, only relying on the limited cooling of the engine oil cannot completely cool the shaft, which will cause excessive heat generation and affect the efficiency and service life. Its main purpose is still lubrication, and the device of the present invention solves this problem. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a turbine shaft, which can solve the above-mentioned problems in the prior art. [0004] The pres...
