Problems solved by technology

[0002] The turbine blades of gas turbines are often manufactured and processed in one piece, and the one-piece turbine blades are cut into one piece by using the whole blank under the action of the machining center. In the case of damage, it is difficult to replace and repair. There is an urgent need for an assembled turbine blade, and it is difficult to change the angle of the turbine blade during actual work. This equipment effectively solves this problem

Abstract

The invention discloses a blade for a turbine of a gas turbine. The blade comprises a bottom box fixedly arranged on the ground, wherein a lower open cavity with an upward opening is fixedly formed inthe upper end surface of the bottom box, a penetrating cavity is formed in the right end wall of the lower open cavity in a communicating mode, a track cavity is formed in the upper end wall of the penetrating cavity in a communicating mode, and a connecting cavity is formed in the lower end wall of the penetrating cavity in a communicating mode, a motor-driven main meshing gear is rotatably arranged in the connecting cavity, and a sealing plate is arranged above the main meshing gear in a meshing mode; and the sealing plate is in sliding fit connection with the track cavity. The blade is simple in structure and convenient to use. The blade adopts a thread adjusting method and utilizes gear meshing functions such as bevel gear transmission to realize the angle change function of turbine fan blades. A connecting rod type working mode is adopted to realize opening and closing of related closed valves, and thus the practicability of the blade is effectively improved.

Description

technical field [0001] The invention relates to the field of gas turbines, in particular to blades for gas turbine turbines. Background technique [0002] The turbine blades of gas turbines are often manufactured and processed in one piece, and the one-piece turbine blades are cut into one piece by using the whole blank under the action of the machining center. In the case of damage, it is difficult to replace and repair. There is an urgent need for an assembled turbine blade, and it is difficult to change the angle of the turbine blade during actual work. This equipment effectively solves this problem. Contents of the invention [0003] The object of the present invention is to provide a blade for a gas turbine turbine that overcomes the above-mentioned drawbacks of the prior art. [0004] According to the present invention, the blades used for gas turbine turbines of the equipment of the present invention include a bottom box fixed on the ground, a lower open cavity wit...
