The invention provides a pneumatic motor which comprises a shell, a spindle and a plurality of impeller units. The shell is provided with a power output side and an exhaust side. An air inlet is formed in the side, close to the power output shaft, of the shell. A curve surface unit is disposed in the shell. The outer contour of the curve surface unit is of a streamline form to reduce motion resistance of high-pressure air flows. An air chamber is formed between the shell and the curve surface unit, so that high-pressure air can enter the air chamber through the air inlet in the shell. One end of the spindle which is a power output end penetrates the curve surface unit and extends out of the shell from the power output side of the shell. The impeller units are serially connected to the spindle and closer to the exhaust side as compared with the curve surface unit. Each impeller unit comprises a stator impeller and a rotor impeller. The high-pressure air entering the air chamber is guided to the impeller units along the curve surface unit, the rotor impellers in the impeller units are driven to rotate, and the spindle is driven to rotate.
Description
technical field [0001] The present invention relates to an air motor, in particular to an air motor driven by compressed fluid or air. Background technique [0002] The air motor is a pneumatic actuator that converts the pressure energy of compressed air into mechanical energy and generates rotational motion. The air motor realizes the transformation of pressure energy into mechanical energy through the expansion of compressed air and the change of solvent by the pressure of gas. Its function It is equivalent to an electric motor or a hydraulic motor and can be used as a rotating power source. The air motor has many advantages. For example, the air motor uses air as the medium, and does not need to deal with the used air, and will not cause environmental pollution; another example, the speed and output of the air motor can be adjusted by the flow of compressed air. power. Moreover, the air motor is not affected by high temperature, high magnetism, radiation, etc., and is s...
