Description
Technical field
A kind of improved rolling mill bearing sealing structure is the utility model is related to, belongs to sealing device technical field.
Background technology
Smelter cold rolling mill bearing block is broadly divided into journal bearing and thrust bearing two parts, as shown in figure 1, mainly
Including bearing block casing, thrust bearing and journal bearing.Roll axial direction movement clearance is responsible in thrust bearing part, and lubrication is used and followed
Ring thin oil lubricant mode, thrust bearing are installed in bearing block casing by thrust bush, and the side of thrust bearing is stopped for outside
End cap is pushed away, textile rubber oil seals are installed in the oil seal groove of outside thrust end cap；End cover is installed on outside thrust end cap by bolt
On, for fixing textile rubber oil seals；There are textile rubber oil seals mounting groove, textile rubber oil seals installation in the bearing block casing of thrust bearing opposite side
In in groove, inner seal end cap is installed on bearing block casing by bolt, for the textile rubber oil seals being fixedly mounted in groove；Bearing
Thrust bearing both sides in seat-box body are provided with outside oil-sealing sleeve and inner side oil-sealing sleeve.Journal bearing is installed on bearing block casing
It is interior, fixed by journal bearing end cap, using grease lubrication；Big a pair textile rubber oil seals, water seal are installed in journal bearing end cap

Gap.
A kind of above-mentioned improved rolling mill bearing sealing structure, the oil sealing groove width that the outside thrust end cap inner ring opens up
Spend for the width of 2 textile rubber oil seals；The inner seal end cap is annular shape, and its inner ring opens up close close to the side of thrust bearing
Sealing groove, axial direction of the seal groove along inner seal end cap open up, and width is the width of 1 textile rubber oil seals；The journal bearing end cap
It is made up of outer edge and flange part, flange part is provided with a radial direction gap.
2 textile rubber oil seals of installation in the oil seal groove of thrust end cap, form double containment on the outside of the utility model；Inner seal end
Increase 1 textile rubber oil seals in the seal groove of lid newly, double containment is also formed with original textile rubber oil seals in bearing block casing；Work as lubricating oil
Into in the shoe cream room of thrust bearing, in the presence of the double containment of both sides, even if a wherein seal failure, another sealing is still
Work, sealing function can be played very well, reduce oil leak.The flange part of the utility model journal bearing end cap opens up footpath
To gap, when journal bearing end cap is installed, it is ensured that radial direction gap be located at the bottom of journal bearing end cap, and journal bearing is using oily
Grease lubrication, when part emulsion flows into bearing block inner chamber from V-arrangement water seal to big textile rubber oil seals, by journal bearing end cap bottom
Opening position is discharged, and so as to effectively avoid the immersion that emulsion seals to bearing (ball) cover steel skeleton, ensures bearing (ball) cover steel skeleton
The sealing effectiveness of sealing, effectively prevent emulsion from entering bearing.
The beneficial effects of the utility model are：
The utility model rolling mill bearing thrust bearing both sides use double containment, effectively reduce the leakage of lubricating oil, reduce
Pollution of the lubricating oil to emulsion of rolling mill；The radial direction gap of milling train journal bearing end cap bottom processing, can enter emulsion
