What is a gear reducer？ 

The gear reducer uses the gear transmission of all levels to achieve the purpose of speed reduction. It is composed of gear pairs of various stages, for example, the gear can be driven by a pinion to achieve a certain deceleration. By using a multi-stage structure, the speed can be greatly reduced.
Gear reducer is generally used for transmission equipment with low speed and increased torque. The motor, internal combustion engine or other high-speed power is meshed with the large gear on the input shaft of the reducer to mesh the large gear on the output shaft to achieve the purpose of deceleration. Ordinary reducers will also have several pairs of identical gears to achieve the desired deceleration effect, the ratio of the number of teeth of the large and small gears is the transmission ratio. 

The meaning of the gear reducer 

    The gears of the two gears mesh with each other to transmit mechanical transmission of power and motion.
The relative position of the gear axis is divided into a parallel shaft cylindrical gear reducer, an intersecting shaft bevel gear reducer and a staggered shaft helical gear reducer. Compact structure, high efficiency and long life.

Gear reducer introduction 

The external meshing involute helical gear reducer produced by the national professional standard ZBJ19004 is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical, textile, printing and dyeing, pharmaceutical and other fields. The scope of application is as follows:
1. The high speed shaft rotation is not more than 1500 rpm.
2. The peripheral speed of the gear drive is not more than 20 m / s.
3. The working environment temperature is -40-45 °C. If it is lower than 0 °C, the lubricating oil should be preheated to above 0 °C before starting, and it can be used in both positive and negative directions. 

Gear reducer features 

1. The gear is made of high-strength low-carbon alloy steel by carburizing and quenching. The hardness of the tooth surface is up to HRC58-62. The gears are all CNC grinding technology with high precision and good contact.
2. High transmission rate: single stage is greater than 96.5%, double level is greater than 93%, and third level is greater than 90%.
3. Smooth operation and low noise.
4. Small size, light weight, long service life and high carrying capacity.
5. Easy to disassemble and easy to install.
