Description
Technical Field
The utility model provides a sealing mechanism especially provides a sealing mechanism of high-speed wire rod rolling mill roll below roll neck position department, belongs to mechanical seal technical field.
Background
Wire rod rolling mills are mills that are specially used for rolling wire rods. The wire rod is the product with the smallest section size in the section bar, the finished product is rolled from the blank, the total elongation coefficient is large, and the rolled piece is usually rolled on each rolling mill only once, so the wire rod rolling mill is the rolling mill with the largest number of racks and the finest division in the hot rolling section bar. Oil film bearings are generally used between two ends of a roller and a bearing seat of the existing large-scale rolling mill, when the rolling mill runs, the emulsion washes the surface of the strip steel to take away the rolling heat energy of the rolling mill, so that the lubricating capability is improved, and the oil film bearing has good effects on reducing the load of the roller, reducing the thermal deformation of the strip steel and improving the quality of a cold-rolled plate. But spray cooling also poses potential threats to the water leakage prevention of the rolling mill bearing, a large amount of emulsion can splash everywhere, if the bearing seat is not tightly sealed, the outside water can take away the lubricating oil in the bearing, and the oil and the water are mixed. Oil-water mixture can lead to the lubricating oil quality to descend, reduces the lubricated effect of bearing, and the bearing body rusts, and bearing ball and raceway wearing and tearing aggravation influence the normal life of bearing, easily produce equipment trouble simultaneously, lead to unexpected shut down, influence unit production.
The existing commonly adopted water seal and oil seal double waterproof structure has the advantages of simple structure and easy manufacture, but has poor seepage prevention capability on jet water flow with high pressure and large impact force, and obviously insufficient wear resistance and compensation capability of a lip. Therefore, a new waterproof structure is urgently needed to ensure the smooth production. At present, various sealing mechanisms in the field are produced in a large number, and have different sealing performances, wherein the sealing mechanisms are complex or simple in structure. In general, however, it would be desirable to provide a seal mechanism that has a simple structure, good sealing performance, and a long service life.
