Turbine pneumatic motor

Abstract

A turbine compressed motor comprises a motor housing and an output shaft. A counterpunched micro-turbine is arranged inside the motor housing and comprises a vent, a turbine stator, a turbine rotor, a turbine shaft and an air inlet, wherein the turbine shaft is connected with the inner end of the output shaft through a decelerating mechanism of a planet gear wheel; a sealing device is arranged between a first bearing close to the turbine rotor, the turbine rotor and the turbine stator; and an annular gas path is formed between the left part of the outer surface of the sealing device, the motor housing and the turbine stator, and communicated with the air inlet. The compressed motor has the advantages of high efficiency, low working pressure, high rotating speed, high power density, long service life and easy maintenance; and no lube needs to be added to the working gas, and the motor has broad aspects for application in the field of industrialized automatization and to compressed tools.

Description

technical field [0001] The present invention relates to a turbo pneumatic motor, in particular to a new type of pneumatic motor with the characteristics of high efficiency, low working pressure, high rotational speed, high power density, long working life, easy maintenance and no need to add lubricating oil to the working gas. The invention relates to the application of volumetric air motors that can replace vane type, gear type, etc. in the field of industrial automation and pneumatic tools, and belongs to the field of energy and power technology. Background technique [0002] As one of the two typical actuators (air cylinder and air motor) of the pneumatic system, the air motor is the basic element that converts the energy contained in the compressed air into mechanical energy and outputs rotary motion, which is equivalent to an electric motor or a hydraulic motor. Because the air motor has the characteristics of safe work, anti-flammation and explosion-proof, anti-electro...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned deficiencies such as low efficiency, high working pressure, and poor energy utilization rate of the volumetric air motor, the purpose of the present invention is to provide a new type of air motor, that is, a counterattack turbo air motor, which counterattack turbo air motor It converts the available enthalpy drop (not only pressure energy) of the gas working medium into mechanical energy. Except that the gas working medium does not need to add lubricating oil, it also has high efficiency (up to 65%) and low working pressure (3 ~4bar), long life and easy maintenance etc.
