Problems solved by technology
[0004] This method mainly has the following problems: one is that the airflow mainly works on the outside of the rotor blades, and the airflow that passes through is often only worked on part of the rotor blades, and is discharged through the exhaust holes, and the utilization efficiency of the airflow is not high; It can be discharged in time to form "back pressure resistance" and affect the rotation of the rotor
The above two "contradictory" points greatly restrict the conversion efficiency of the airflow in the air motor, and it is difficult to increase the motor speed

The invention discloses a pneumatic motor, which comprises a casing and a rotor rotatably arranged in the casing. The rotor is fixedly provided with a hollow rotating shaft passing through the casing, and an air inlet is opened on the side wall of the casing. The rotor is composed of two or more rotor units arranged in sequence from the outside to the inside, each rotor unit includes three arc-shaped or straight-shaped rotor blades, the three rotor blades are enclosed in a triangle, and the adjacent rotor blades are kept between the head and tail. The air intake gap, the air intake gap of the adjacent rotor units is staggered, the rotor units form a certain angle of deflection layer by layer, so that there are airflow channels between the adjacent rotor units; the hollow part formed by the innermost rotor unit Connect the hollow shaft. The present invention provides an air motor, which can realize efficient air flow utilization by driving the rotor inside, so that the air flow introduced from the outside is used multiple times inside the rotor, so as to obtain more efficient efficiency conversion and rotational speed.
Description
technical field [0001] The invention relates to the technical field of power devices, in particular to an air motor. Background technique [0002] An air motor is a device that converts compressed air potential energy into mechanical energy, and is widely used in various power fields. [0003] Existing air motors mainly include a housing and a rotor disposed in the housing, and the power output (mainly reflected in the rotation of the rotating shaft) is realized through the rotation of the rotor driven by the airflow. CN2014204432512 provides an air motor, and the air motor disclosed in CN201611031078 mainly uses compressed air to drive the outer side of the rotor to achieve rotation and finally realize the rotation output of the shaft. [0004] This method mainly has the following problems: one is that the airflow mainly works on the outside of the rotor blades, and the airflow that passes through is often only worked on part of the rotor blades, and is discharged through ...
