Abstract
The utility model provides a novel-structure multi-lip rubber sealing ring which is provided with a plurality of lips which have the functions of stabilization, activation and automatic sealing. An inner and an outer metal spring skeletons are arranged, wherein, the inside of the inner spring skeleton is provided with a plurality of steel wire cores; in addition, the mouth of each of the lips has a unique shape and a unique angle. The reasonable and perfect structural form better improves the sealing effect and extends the service life of the sealing ring. Besides sealing rolling mills in a steel works, the utility model is also used for sealing other metallurgical machines, mine industrial equipment, etc.
Description
The utility model relates to a kind of many lips rubber seal, be applicable to the sealing of steel mill's milling train supporting roller bearing.Be particularly useful for the sealing of hot rolling mill.
Milling train back-up roll rubber seal is the indispensable vitals of rolling mill transmission system, plays rotary seal in the milling train operation process, is in desirable lubricating status to guarantee the bearing in the transmission system, thereby reaches the purpose of proper functioning.
The hot rolling mill supporting roller bearing at high temperature turns round, and operating conditions is very harsh.The rubber seal of installing at this position was general structural type in the past, and the lubricant oil of bearing portion is leaked easily, and simultaneously, the cooling water that the spray roll is used immerses bearing, caused mixing of oil and water.Because of costing an arm and a leg of used senior lubricant, so the mixing of water oil will bring very big economic loss; In addition, milling train operate to continuous production line, the water content in oil surpasses certain limit, is then directly threatening the normal operation of milling train, in case shut down, its loss is bigger.Existing seal ring can not satisfy the needs of actual use.In order to overcome the problem of above-mentioned existence, must on structure, be improved, can reach usage requirement.
The purpose of this utility model is to provide a kind of novel many lips rubber seal, and it can further improve sealing effect, economizes on the use of funds, and can prolong its working life again.
Task of the present utility model is to finish by the structure of improving sealing lip and skeleton and shape.
Below with reference to accompanying drawing the utility model is described in further detail.
Fig. 1 is the view in transverse section of a kind of concrete structure of the present utility model.
With reference to Fig. 1, the utility model is made up of oily static lip (1), oily static lip (2), hydrodynamic(al) sealing lip (3), oily movable sealing lip (4), oil removal lip (5), inner spring skeleton (6) and spring groove (7).
During the milling train operation, many lips rubber seal is embraced axle tightly, forms bigger seize power, and rotates with axle, and (1), (2) lip can not leak from leaning on axle one side oil, Water breakthrough is entered; Oil removal lip (5) plays cushioning effect to the impulsive force from bearing clearance oil, then, is sealed by (4) again. Like this, then can be better to the sealing effectiveness of lubricating oil.
(3), the shape of (4) lip can be linear, but because the arc lip under the effect of fluid pressure, and is coupling closelyr tactilely, easier, namely its self sealss effect is better than linear; In addition, the sealing surface of lip (1) and the angle of its end face can be the right angles, but when its angle is acute angle, and the component that produces from the oil pressure of oil pocket increases seize power, the radial pressure that just makes sealing ring act on axle increases, and has in improving sealing effectiveness from face.
The operating temperature of hot rolling mill is very high, need carry out spraying cooling with cooling water, and through holding the first road seal action of envelope water shutoff one side, anti-sealing mixes with oil, carries out the sealing of second road by (3) again, has then further prevented water and oily mixing.
Inner spring skeleton (6) also has the Steel Wire Strand core except that metal spring is arranged, to increase the seize power of seal ring.
Insert the metal spring of pre-stretching in the spring groove (7), so that the radial seal effect further improves.
Many lips rubber seal of the present utility model, its structural design is more reasonable, and is perfect, good sealing effect, the life-span is long, except that the sealing that is used for the milling train supporting roller bearing, can also be used for the sealing of equipment such as other metallurgical machinery, mine industry.
Claims (4)
1, a kind of many lips rubber seal, by lip, the inner spring skeleton, spring groove is formed, it is characterized in that having oily static lip (1), oil static lip (2), hydrodynamic(al) sealing lip (3), oil motive sealing lip (4), (5) five lips of oil removal lip, oil static lip (1) and oily static lip (2) are held axle tightly during operation, and rotate with axle, oil can not be leaked from leaning on axle one side, water can not scurried into yet simultaneously, and hydrodynamic(al) sealing lip (3) will carry out the sealing of second road through the water after first road sealing of end envelope water shutoff one side, and anti-sealing mixes with oil, oil removal lip (5) plays buffer function to the impact force from bearing play oil, and then is sealed by oily motive sealing lip (4).
2, by the described many lips rubber seal of claim 1, it is characterized in that hydrodynamic(al) sealing lip (3), the sealing surface of oily motive sealing lip (4) is an arc, and the sealing surface of oily static lip (1) and the angle of its end face are acute angle.
3,, it is characterized in that having in the spring groove (7) metal spring of pre-stretching by the described many lips rubber seal of claim 1.
4,, it is characterized in that in the inner spring skeleton (6) except that spring is arranged, also having the Steel Wire Strand core by the described many lips rubber seal of claim 1.
