Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a piston type air motor having improved rotational speed and energy efficiency,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a piston-type air motor in which efficiency is improved by improving the structure in which air is moved and friction is reduced.

Generally, air motors are used variously in various devices requiring torque (torque) like an electric motor, and the driving power source is a motor operated by compressed air rather than electricity.

These air motors are divided into large-sized and piston-shaped air motors, which are actuators that convert compressed air energy into mechanical rotational energy. The forward, reverse, and reverse rotations are controlled by directional control valves.

In particular, compared to an electric motor, an air motor is smooth in starting and stopping, and its output / weight ratio is large. Because of the compressibility of the air, the rotation speed is easily influenced by the load but is safe against overload.

In addition, it can be safely used even in an explosive atmosphere, and it is easy to change the speed control and the forward / reverse rotation, and is not limited by the motor as much as the ambient temperature and humidity in use. .

In addition, frictional heat of each sliding part is cooled by adiabatic expansion of compressed air, and besides compressed air, nitrogen gas, carbon dioxide gas and the like can be used. If an air tank is installed, emergency operation is possible for a short time during power failure.

Accordingly, the development of an air motor having an improved efficiency by improving the structure of such an air motor is in the process of being developed.
