Involute helical cylindrical gear reducer:
Widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical and other fields.
Scope of application:
1.Speed of high speed shaft is less than or equal to 1500 revolutions per minute;

2.The circumferential speed of gear transmission is less than or equal to 20 meters per second.

3.The working environment temperature is - 40 - 45. If it is below 0 degree, the lubricating oil should be preheated to above 0 degree before starting. The reducer can be used in both positive and negative directions.

Gear reducer is to use all levels of gear transmission to achieve the purpose of deceleration. Gear reducer is composed of all levels of gear pairs. For example, with small gears to drive large gears can achieve a certain purpose of deceleration, and then the use of multi-level structure, you can greatly reduce the speed.
Gear reducer
Gear reducer is an external meshing involute helical cylindrical gear reducer manufactured according to the national professional standard ZBJ19004. Gear reducer is a rotating mechanism widely used in East China for tower crane machinery. It is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and so on. Dyeing, pharmaceutical and other fields.
Scope of application
1, high speed axle rotation is not greater than 1500 rpm.
2, the circumferential speed of gear transmission is not greater than 20 m / sec.
3, the working environment temperature is -40-45 C, if the temperature is below 0 C, the lubricating oil should be preheated to more than 0 C before starting.
4, gear reducer can be used in two directions.
Machine features
1. The gear is made of high-strength low-carbon alloy steel by carburizing and quenching. The hardness of the tooth surface reaches HRC58-62. The gear is grinded by NC grinding technology. The precision is high and the contact is good.




2. transmission rate is high: single stage is greater than 96.5%, two-stage is greater than 93%, and three 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 remove and easy to install.
