Gas compressor

Abstract

The invention discloses a gas compressor, which comprises a variable speed transmission mechanism and a gas compression mechanism. An impeller of the gas compression mechanism is fixed at the front end of a wheel axle, the center of a shell is provided with an air inlet, the periphery of the shell is provided with an air outlet, the rear end of the shell is provided with a rear plate, and the rear plate is fixedly connected with the shell and a box body; the variable speed transmission mechanism comprises a box body, a main shaft, a driving gear, and a driven gear; the rear part of the main shaft is provided with the driving gear which is fixedly connected with the main shaft, both sides of the driving gear are provided with a No.1 bearing and a No.2 bearing which are rotatablely connected with the main shaft, and the No.1 bearing and the No.2 bearing are fixed on one side of the box body; the driven gear is fixed on the wheel axle, both sides of the driven gear are provided with a No.3 bearing and a No.4 bearing respectively which are rotatablely connected with the wheel axle, and the No.3 bearing and the No.4 bearing are fixed on the other side of the box body; and the driving gear and the driven gear are engaged with each other. The gas compressor has the advantages of scientific design, strong practicability, compact structure, less material consumption, low cost and steady performance, and is suitable to be matched with high-pressure engines of spacecrafts and the like.

Description

technical field [0001] The invention relates to a compressor, in particular to a high-efficiency compressor capable of generating high pressure, extremely stable output flow and pressure, long service life, stable and reliable performance. Background technique [0002] The compressor is an integral part of the turbocharger, that is, the exhaust gas discharged from the engine drives the turbine, and the rotation of the turbine drives the impeller of the compressor to rotate, which is the whole process of the compressor implementing the compression. Although the intake air boosting of the engine is a relatively mature technology, and the forms of the compressor are also various, under the specific environment and conditions of use, sometimes the compressor cannot work stably and reliably, especially in low-speed operating conditions. The problems exposed below are more serious. It often shows that the pressure and flow of the output gas are not stable enough, and the temperat...
