Summary:...
Helical planetary gearbox is a kind of hardened surface reducer, which is widely used in construction equipment, mining equipment, submarine oil machinery and other large equipment.
The gear of the helical gear hardened reducer is forged from high-quality low-carbon alloy steel. After carburizing and quenching, gas carburizing and other processes, the hardness of the gear is greatly improved, and its bearing capacity is much higher than that of ordinary gears. It is a rolling mill, etc. A necessary reducer for high-strength and high-torque work machines. Ordinary gear reducers can't bear the load of rolling mill speed up to 90-120m/s at all, only the helical gear hardened reducer with gear precision up to grade 3 can take on this important task.
Why does the gear reducer use helical gears instead of ordinary gears? Helical gears are "cylindrical gears with helical tooth lines", and different from ordinary helical gears, they adopt the advanced design technology of the modular combination system, which can withstand greater torque and operate smoothly and accurately. With the characteristics of small size and light weight, it has become a special gear for large mechanical gear reducers. The helical gear hardened surface reducer is made of such a combination of helical gears that have been hardened and processed with precision, and has gained a good market in various large-scale machinery.
The helical gear hardened surface reducer has strict requirements in use. On high-power machinery, the speed of the high-speed shaft should not be greater than 1500 revolutions per minute, and the peripheral speed of the helical gear transmission should not exceed 20 meters per second. In the working environment, the helical gear hardened surface reducer can work normally at minus 40 ℃, but the lubricating oil should be heated to above 0 ℃.
