What are the characteristics of the special reducer for Steel Rolling Mill Machines
I believe everyone is familiar with Steel Rolling Mill Machines, so what is the special reducer for Steel Rolling Mill Machines, and what are the main features? The following Steel Rolling Mill Machines manufacturer will lead you to learn about the relevant knowledge of Steel Rolling Mill Machines special reducer.
The working characteristics of the special reducer for Steel Rolling Mill Machines are low speed, heavy load, large impact load, frequent impact times, and continuous operation. With the rapid development of my country's steel rolling industry, the continuous expansion of steel varieties, the increase in output, the increase in rolling speed, and the increase in rolling load, the rolling mill gear transmission is required to have sufficient bearing capacity, that is, high strength, high precision, Long life and high reliability.
Therefore, modern large and medium-sized rolling mill gear devices generally use finished hard-toothed and medium-hardened involute cylindrical gears, and use design and manufacturing technologies such as gear tooth modification, deep carburizing, and shot peening. Welded reducers are also widely used. The reducer box and cover are all welded structure, and the welded large gear structure gradually replaces the past cast gear and ring gear structure.
The main reducer used in the transmission of Steel Rolling Mill Machines mostly adopts two types of cylindrical gear reducers, one-stage and two-stage. The reducer gears used by Steel Rolling Mill Machines are mostly made of herringbone teeth, because this gear works relatively smoothly and does not generate axial force on the bearing.
In the two-stage reducer, in order to adapt to the change of the load, the split flow is generally used. The high-speed stage is meshed with two pairs of symmetrical helical gears, and the low-speed stage is mostly made of herringbone teeth. The tooth width is evenly distributed and the bearing is evenly loaded. The torque on the critical section of the intermediate shaft of Steel Rolling Mill Machines is equivalent to half the torque transmitted by the shaft.
