Maintenance and function of Gearbox used for rolling mills

Gearbox used for rolling mills are mainly used for high-speed wire rod, bar, profile and other steel rolling production lines. In the rolling mill transmission device, its role is to transmit and distribute the power of the motor to two or three rolls, and meet the requirements of the rolling mill through the reduction ratio. For the required torque and speed, the production line adopts horizontal and vertical gearboxes arranged alternately, so as to realize continuous and twist-free high-speed rolling of billets.

 
The working characteristics of Gearbox used for rolling mills are low speed, heavy load, large impact load, frequent impacts, and continuous work.

In order to further strengthen the management and functions of Gearbox used for rolling mills, ensure its safe and controlled operation, and meet the needs of stable operation of production, it is necessary to carry out necessary maintenance and maintenance for Gearbox used for rolling mills.

1. Oil change
Gearbox used for rolling mills should be changed after the first 6 months of operation, and the gearbox should be flushed. In the future, the lubricating oil will be replaced once a year for no more than 15 months. It is recommended to clean the gearbox after changing the oil.
2. Make good operation and maintenance records:
Daily record of Gearbox used for rolling mills working load, speed, lubricating oil temperature, bearing temperature. If there is any abnormal change, it should be analyzed and researched in time to find the problem as soon as possible.
3. Maintenance inspection
After 48 hours of operation of Gearbox used for rolling mills, all fasteners are checked once to see if they are loose. And recheck the axis alignment. Check regularly in the future. It is recommended that the ventilation hood on Gearbox used for rolling mills be cleaned once every six months.
