The purpose of reducing the speed of the pneumatic motor through the reduction gear to increase the

The working principle of pneumatic motor is similar to that of hydraulic motor. Compressed air enters from transmission line A. Acting on the blades on both sides of the studio. Due to the eccentric installation of the rotor, the torque difference caused by the air pressure acting on the blades on both sides makes the rotor rotate counterclockwise. When the eccentric rotor rotates, the volume of the working chamber changes, resulting in a pressure difference on the blades of the adjacent working chamber, which is used to drive the rotor to rotate. The gas after work is discharged from the output port. If the compressed air input direction is changed, the rotation direction of the rotor can be changed.

Structural principle of gear reduction pneumatic motor

When the compressed air enters the air chamber from the left air port, it immediately sprays into the blade and acts on the extended part of the blade to generate torque to drive the rotor to rotate along the needle and output the rotating mechanical energy. The waste gas is discharged from the middle air port and the residual gas is discharged from the right air port; If the left and right air ports are interchanged, the rotor reverses and outputs mechanical energy in the opposite direction.

The centrifugal force of rotor rotation and the air pressure and spring force at the bottom of the blade make the blade closely against the inner wall of the pneumatic motor to ensure sealing and improve volumetric efficiency.

The deceleration pneumatic motor reduces the speed of the pneumatic motor through the deceleration gear, so as to increase the torque of the motor.

Principle of piston pneumatic motor

In order to obtain linear motion from compressed air, piston system is commonly used. The compressed air is fed into a sealed chamber, which is equipped with a piston shaft. In this chamber, the spring is wound around the piston shaft to keep the chamber fully open when air is not pumped into the chamber. When air enters the cavity, the force on the piston shaft begins to overcome the force applied to the spring. As more and more air enters the combustion chamber, the pressure increases and the piston begins to move down the combustion chamber. When it reaches a large length, the air pressure is released from the chamber, and the spring completes the cycle by closing the chamber and returning to the original position.

Piston pneumatic motor is a commonly used pneumatic motor in hydraulic system. In essence, piston engines are the same as hydraulic engines, except that they are used to convert hydraulic energy into mechanical energy. Piston engines usually use a series of two, three, four, five or six cylinders, which are encapsulated in a shell. This allows the piston to provide more energy because several motors are synchronized at a specific time of their cycle.
