The invention discloses a rotary piston air-driven motor, including stator component, where the inner hole is columnar, the middle of two side surfaces of the stator symmetric to the axis is made with air inlet cavity and exhaust cavity, and the air inlet cavity leans tightly against one end of the exhaust cavity; rotor component, where the rotor is columnar, a piston is held in the side columnar hole and linked with one end of the link rod by piston pin, the other end rotates around a fixed point, the side surface of the stator or rotor is installed with sealing ring or groove or not, the rotary radius of the link rod is half of the rotor's, and one end of the link rod or the rotor is the torque output end. When it works, the piston rotates all the time, and runs a circle to automatically complete charging and exhausting without air distributing mechanism. When the piston rotates a circle, it completes two pressure circulations. The piston is equivalent to two ones of reciprocating piston air-driven motor. It has good technical and sealing properties, and high integrative efficiency.
Description
Technical field [0001] The present invention relates to an air motor, in particular to a rotary piston air motor. Background technique [0002] In the existing piston-type air motors, the pistons are all reciprocating. Because the inertial force of the reciprocating motion needs to be overcome, the energy consumption is large, the operation is unbalanced, and the noise is large. And the gas distribution mechanism is complicated. Therefore, the overall efficiency of the motor is relatively low. Contents of the invention [0003] The object of the present invention is to provide a rotary piston air motor. The piston is always rotating when the air motor is running, and it runs for one cycle, and automatically completes the air intake and exhaust, without the need for air distribution mechanisms such as intake and exhaust valves. The piston rotates once to complete two pressure cycles. [0004] In order to achieve the above object, the technical scheme adopted in the prese...
