It is reported that at present, the domestic metallurgical industry has started to use a rolling mill that drives the rolls in three separate units. The market demand is large, and most of them are imported from abroad. However, the drive shaft of the imported equipment adopts a hollow split body structure, and there is no positioning support at both ends of the telescopic part, which may cause the front-end coupling to droop; the collision during docking may damage the equipment; at the same time, the gear box has a complex structure and is inconvenient to adjust and maintain. Jiangsu Jinxiang provides a special gear reduction box for a three-high rolling mill. Its advantage is that the drive shaft adopts spline as a moving pair and can be rotated or moved axially; the return spring is installed in the hollow output shaft and has sufficient pre-load. The tight force ensures that the drive shaft can be automatically reset after the Hydraulic Cylinder pulls back and pressure is released. It is easy to manufacture and easy to install and maintain. It can realize rapid rack change, free rolling within a certain specification range, and guarantees trouble-free operation of the rolling mill with reliable and safe performance. . The gearbox can be used for both hot strip mills and tandem cold mills. It can be used for reducers as well as sizing mills and precision sizing mills.
