Structure: it adopts bevel gear + planetary gear direct transmission, the reducer and mill are integrated, the output flange is directly connected with the grinding plate to transfer torque, and at the same time, it is subject to the pressure from the grinding roller.
The bevel gear pair adopts Klingelnberg gear system, the bevel gear, sun gear and planetary gear adopt carburizing quenching furnace grinding technology, and the sun gear and planetary gear adopt the company’s special modification technology and tooth root strengthening shot peening technology.
The inner gear ring adopts the latest design and manufacturing technology, and the accuracy is above grade 5 (iso1328).
All gears are detected at blank stage and after final heat treatment, and the main welds of box and planetary carrier are detected by ultrasonic. The use of advanced automatic welding equipment and welding process to ensure the high strength and high rigidity of the turret.
In the reducer of high-power vertical mill, the flexible connection of the output flange and the output shaft with drum teeth is adopted to further reduce the impact on the gear pair caused by the change of load.
Using dynamic and static pressure, static pressure lubrication system, more safe and reliable.
The optimization design of bearing bush is carried out with the latest optimization software developed by our company.
The service life of all rolling bearings is more than 80000 hours.
Lubricating oil grade: N220 ~ 320 (GB / t5903-1995).
It has the features of light weight, low noise, high efficiency and so on.
Simple structure, safe and reliable, easy to install and maintain.
The main technical indexes of this series of reducers have reached the latest advanced level of similar products at home and abroad.
