AI Technical Summary
In existing technologies, during the rolling process, emulsion tends to flow into the bearing housing along the roll surface, leading to poor bearing lubrication and damage. Furthermore, the labyrinth waterproof structure is costly, difficult to assemble, and prone to wear.
The system employs a water-slinging ring and a water-blocking ring structure. The water-slinging ring rotates with the vertical roller to throw away the emulsion, while the water-blocking ring blocks residual liquid to prevent the emulsion from entering the bearing housing. Combined with a fixing ring plate to fix the water-blocking ring, it ensures that the emulsion does not enter the bearing housing.
It effectively prevents emulsion from entering the bearing housing, extends bearing life, reduces processing difficulty and wear risk, and improves equipment reliability.

TECHNICAL FIELD
[0001] The utility model relates to rolling mill technical field, concretely relates to a kind of vertical roll bearing waterproof device. BACKGROUND
[0002] Currently, hot rolling mill is usually used to process aluminum slab ingot, and the vertical roll is used to roll the edge of aluminum slab ingot. For the assembly of the vertical roll, the vertical roll is usually installed through bearings, and the bearings are installed in the bearing box. However, during the rolling process of the edge of aluminum slab ingot by the vertical roll of the hot rolling mill, emulsion needs to be sprayed on the surface of the vertical roll for lubrication and cooling. Due to the vertical assembly structure of the vertical roll, the emulsion is easy to flow into the bearing box below the vertical roll along the surface of the vertical roll, which causes the deterioration of gear oil, leads to poor lubrication of the bearings and damage, and seriously affects the service life of the bearings.
[0003] The prior art usually adopts a labyrinth type waterproof structure to avoid the emulsion flowing into the bearing box. However, the labyrinth type waterproof structure has high cost, and requires to separately manufacture a rotating structure rotating with the vertical roll and a fixed structure fixed on the bearing box. Multiple seals need to be installed between the two structures, and the spacing between the multiple seals requires to be high, which leads to high processing cost. In addition, the assembly of the vertical roll is difficult. Since the gap between the multiple labyrinth seals is small, the sealing structure is easy to be damaged during the hoisting and assembly of the vertical roll, which affects the sealing effect, and even the vertical roll cannot be assembled in place. At the same time, since the impact and vibration are large during the rotation of the vertical roll, and the gap between the labyrinth seals is small, the wear between the rotating structure and the fixed structure is easy to occur, which reduces the service life of the rotating structure and the fixed structure. In addition, the residues generated by the wear will fall into the bearings below the vertical roll, which causes damage to the bearings. SUMMARY
