Heavy Duty Helical Gear Reducer Gearbox Metallurgical Crane Gearbox Housing
The gear reducer is according to the national standard ZBJ19004 production of external involute helical cylindrical gear reducer, gear reducer is widely used in our country in the East, for tower crane slewing mechanism into the machinery, widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical, textile, printing and dyeing, pharmaceutical etc..
Gear reducer is generally used in low speed, high torque drive equipment, the ordinary motor reducer will also have several pairs of the same principle gear to achieve the desired deceleration effect, the ratio of the number of teeth of the gear is the transmission ratio. With the continuous development of the reducer industry, more and more enterprises use the reducer.
1.The gear is made of high strength low carbon alloy steel through carburization and quenching. The hardness of tooth surface may reach to HRC58-62. All gear adapts NC tooth grinding process, high in accuracy and good in contact performance
2.High in transmission efficiency: single stage, more than 96.5%; double-stage, more than 93%; three-stage, more 90%;
3.Smooth and stable in run, low noise;
4.Compact, light, long life, high bearing capacity;
5.Easy to disassemble, inspect and assemble.
