Abstract

The invention discloses a power transmission mechanism of a gas compressor and a turbine, which is used for a mini-type ground gas turbine. The power transmission mechanism comprises a gas compressor impeller and turbine back tooth transmission mechanism, and a turbine shaft end conical surface nut locking device; the gas compressor impeller and turbine back tooth transmission mechanism is formed by engaging the turbine with a straight-line trapezoid back tooth and the gas compressor impeller with a straight-line trapezoid end tooth with each other; and the turbine shaft end conical surface nut locking device is formed by matching a locking nut with a conical surface with a shell, and is used for axially locking an engaging gear ring. The power transmission mechanism has the advantages of simple mechanism form, low machining cost and reliable transmission; and on the precondition of realizing a power transmission function of the gas compressor and the turbine, the axial size of the gas turbine is effectively shortened and the mechanism compactness is improved.

Description

technical field [0001] The invention belongs to the technical field of power transmission between a compressor and a turbine in a micro gas turbine, and relates to a power transmission mechanism between a compressor and a turbine in a micro gas turbine, specifically, a compressor used in a miniature ground gas turbine Power transmission mechanism with turbine. Background technique [0002] The micro gas turbine is a ground distributed energy power system that my country has focused on research and development for more than ten years. Its main features are small size, high power density, flexible energy supply, wide range of available fuels, energy saving and environmental protection, etc. At present, the country does not have the design capability of the whole machine, and the breakthrough of key technologies is of great significance to the realization of the design ability of the whole machine. The invention proposes a back-tooth transmission mode of a compressor and a tu...
