The Hard tooth surface Helical gear reducers is an external meshing involute helical gear reducer produced according to the national professional standard ZBJ19004. The Hard tooth surface Helical gear reducers is widely used in the East China region and East China region for the slewing mechanism of the tower-introduction crane machinery. It is widely used. In the fields of metallurgy, mining, lifting, transportation, cement, construction, chemical, textile, printing and dyeing, pharmaceutical.

  Hard tooth surface Helical gear reducers is generally used for transmission equipment with low speed and high torque. The ordinary reducer of the motor 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. As the speed reducer industry continues to develop, more and more companies are using reducers.

 

1. Scope of application:
2. The high speed shaft rotation is no more than 1500 rpm.
3. The peripheral speed of the gear drive is not more than 20 m / s.
4. 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.
5. The gear reducer can be used in both forward and reverse directions.
6. 二. Machine features:
7. 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.
8. High transmission rate: single stage is greater than 96.5%, double level is greater than 93%, and third level is greater than 90%.
9. Smooth operation and low noise.
10. Small size, light weight, long service life and high carrying capacity.

 5, easy to dismantle and easy to install.

 

三．In short

1. R, K, S, F four series of Hard tooth surface Helical gear reducers are designed and manufactured on the basis of modular combination system. There are many motor combinations, installation forms and structural schemes. The transmission ratio is finely graded to meet different working conditions. Mechatronics.
2. The four series of gear reducers of R, K, S and F adopt the modular design principle of unit structure, which greatly reduces the types of parts and stocks.

  3, R, K, S, F four series of Hard tooth surface Helical gear reducers transmission efficiency, low energy consumption, superior performance.

4. R, K, S, F four series of gear reducers have high-rigidity cast iron box with ribs. The gears are made of high-quality alloy steel. The surface is hardened by carburizing and quenching. The grinding teeth are finely processed, the transmission is stable and the noise is low. Large carrying capacity, low temperature rise and long life.

  Reduction ratio: 25~4000r/min (combined with RX, R, K series can achieve greater speed ratio)

  Output torque: up to 2600000Nm

  Motor power: 0.4-12934KW
