Pneumatic Gear Motor

 

 

HISCORE Pneumatic Gear Motor is an efficient and reliable power source device. The application range of pneumatic gear motor is very wide. It is widely used in flammable and explosive, chemical enterprises, coal mining operations, oil wellhead tools, etc. In mechanical processing, pneumatic gear motor is used for high-speed grinding, part chamfering, drilling, etc. At the same time, in the field of industrial manufacturing, pneumatic gear motor is also widely used in robots, automatic control systems and production lines. It is specifically used in pneumatic monorail cranes, pneumatic shotcrete machines, pneumatic manned winches, pneumatic grinders, pneumatic mixers and other power equipment. It is a pneumatic actuator that uses the power generated by gas pressure to drive the gear to rotate and work externally. Its function is equivalent to a hydraulic motor or an electric motor. Changing the direction of air intake can change the direction of the gear motor, that is, it can achieve forward and reverse rotation.

Pneumatic gear motor is an efficient, reliable, safe and environmentally friendly mechanical device that is widely used in various fields. In the future, with the continuous development of science and technology, the application prospects of pneumatic gear motor in various industries will be broader.

The working principle of pneumatic gear motor is to use the pressure of gas to drive the gear to rotate, thereby generating power. The working chamber of the pneumatic motor is composed of a pair of gears. Compressed air is input from the symmetric center, and the gears rotate under the action of pressure. Pneumatic motors using spur gears can rotate forward and reverse, while pneumatic motors using herringbone gears or helical gears cannot reverse. Spur gear pneumatic gear motors can achieve free switching between forward and reverse directions without damaging the internal structure. We can change the direction of rotation of the motor output shaft by changing the intake and exhaust paths.

 

 

Pneumatic gear motor uses compressed air as its power source and has characteristics different from other prime movers such as electric motors and internal combustion engines. The advantages of this type of air motor are:

(1) It is less restricted by ambient temperature, humidity, corrosive substances and dust;

(2) It can be used safely in an environment with explosive gases (such as gas);

(3) It does not pollute the atmosphere, and only a small amount of oil mist is formed in the exhaust gas;

(4) It has a simple structure and a large power per unit weight;

(5) It can operate under overload. When it stops due to overload, it will start again by reducing the load;

(6) It can start under load.

Geared air motors can be divided into three types according to the tooth shape: spur gear, helical gear and herringbone gear. Among them, spur gear air motors have the simplest structure and are easy to process and manufacture, so they are widely used.

 

HISCORE pneumatic gear motor has three main advantages:

1. The internal gear precision is very high. HISCORE uses imported processing equipment throughout the process to ensure that the gear precision reaches level 5, which is at the world's leading level and the energy conversion is more efficient.

2. For the processing of the shell, HISCORE uses imported machining center equipment for shell processing, with a tolerance of 0.01 mm. The internal matching of the shell is more precise, and the actual power is higher when used.

3. HISCORE uses imported NSK bearings from Japan, which are more reliable and durable.

 

Compared with traditional electric motors, pneumatic gear motors have the following advantages:

 

 

Since this type of motor uses compressed air as the power source and gears as the transmission and energy conversion medium, it has different characteristics from other prime movers such as electric motors and internal combustion engines. The rotation, torque and power of the gear-type pneumatic motor will change with the intake pressure, intake volume and load. This is the characteristic curve of the pneumatic motor. When the motor is idling, the speed is the highest and the torque is zero; when the motor is under load, the speed decreases and the torque increases; when the motor is almost stopped, the torque is the highest. As the load increases and the speed decreases, the air consumption will gradually decrease, and the intake pressure will also decrease. The maximum power point of the motor (that is, the rated power point) is at half of the idling speed. At this time, the gear-type pneumatic motor is most efficient in working outward.
