Abstract
The present invention relates to a kind of sealing structures, are made of bearing block, sealing cover, round rubber, tapered sleeve, bushing, roll and water seal arrangement etc., and the aluminum ring device to form water seal is also equipped in the cavity between capping, foot-shape sealing, roll and water seal arrangement.The present invention can effectively stop coolant liquid and dirt enters Bearing inner, effectively prevent the oil leakage of Bearing inner, while water seal is able to use in the filmatic bearing structure of different size, reduces production cost.The defects of such sealing structure water shutoff is stronger, substantially improves original structure water inlet, dirt avoids the accident of entire rolling line cisco unity malfunction caused by occurring to intake because of bearing, improves the service life of filmatic bearing.
Description
Technical field
The invention belongs to the rolling mill bearing fields for rolling metal strip, more particularly to a kind of sealing structure.
Background technique
Currently, the sealing device that roll sealing bearing uses, mainly by sealing cover, aluminum ring device, foot-shape sealing, sealing
The composition such as hoop, water seal.Round rubber is filled on sealing cover, is mounted on bearing block end face by screw, and foot-shape sealing installs sealing
On face, sealing hoop is packed into foot-shape sealing, and aluminum ring device is embedded in the water sealing limb side of foot-shape sealing, the limited several copper of water seal
Screw-driving is on sealing cover end face.They play the work of oil sealing water shutoff together with bearing block, tapered sleeve, bushing, roller combination
With.The disadvantage is that: in actual use, after water seal is mounted on sealing cover end face, there is S-shaped shape, reason in water seal surface
It is water seal is rubber bodies, only by limited several brass screws fastening, it is extremely difficult to be fitted close between sealing cover, will go out
It is existing uneven, big gap is formed, water, impurity, iron scale of Bearing outer etc. is made to easily enter Bearing inner, less serious case
Deterioration of lubricant, aging are caused, bearing service life, the great thing that will also entire rolling line be caused to stop production under serious conditions are reduced
Therefore cause biggish economic loss.
Summary of the invention
It is an object of the invention to overcome the above-mentioned prior art, the present invention be directed to above-mentioned existing sealing structures
What structure improved, more effectively to prevent external water, impurity, iron scale etc. from entering inside filmatic bearing, and provide
A kind of sealing structure improving sealing performance and service life.The cross section of the wear ring is rectangle, trapezoidal or round；Institute
Stating wear ring is that polyformaldehyde adds glass fibre guide ring.
The present invention is achieved by the following technical solutions: a kind of sealing structure provided by the invention, it has using Piao bolt
The sealing cover being mounted on bearing block, the round rubber between bearing block and sealing cover, in sealing cover, tapered sleeve, bushing and roll
The foot-shape sealing being filled between roll neck, the sealing hoop installed on foot-shape sealing on sealing cover end face and are embedded in seal groove
Water seal；The aluminum ring device to form water seal is also equipped in cavity between sealing cover, foot-shape sealing, roll and water seal arrangement；
It is characterized in that there are also pressure ring and hold-down bolts for the water seal, bolt passes through pressure ring and connect with sealing cover, and compresses water seal close
It covers on end face.
Sealing cover is mounted on bearing block end face in sealing structure of the present invention, and foot-shape sealing is inserted in after first installing sealing hoop
On the sealing surface of sealing cover, aluminum ring device is embedded in the water sealing limb side of foot-shape sealing, has seal groove on sealing cover end face, water seal is embedding
Enter in seal groove, on sealing cover, water seal is tightly pressed against on sealing cover end face water seal pressure ring screw-driving by pressure ring.It is this close
Seal apparatus and bearing block, tapered sleeve, bushing, roll form closed oil chamber, on the one hand the oil of Bearing inner are prevented to leak, another party
Face prevents water, impurity, iron scale of Bearing outer etc. from entering Bearing inner, has effectively acted as oil sealing water shutoff, impurity, oxidation
The effect of iron sheet etc..Water seal is tightly pressed against on sealing cover end face by pressure ring, avoid water seal surface occur it is uneven, eliminate
Big gap is formed between water seal and sealing cover end face, so that the water of Bearing outer, impurity, iron scale etc. be made to hardly enter axis
Inside is held, plays first of sealing at this, while constituting labyrinth together with sealing cover, aluminum ring device, effectively prevents
The entrance of coolant liquid and dirt, and it is provided with discharge sump below water seal, so that a small amount of water energy entered sufficiently flows back.And water seal
Structure is more reasonable, and same water seal is able to use in the filmatic bearing structure of different size.The water sealing limb of foot-shape sealing exists
This plays second sealing, further prevents the entrance of coolant liquid and dirt.The effective ground resistance of the seal oil limb of foot-shape sealing
The leakage of oil is stopped.
Beneficial effects of the present invention:
The present invention can effectively stop coolant liquid and dirt enters Bearing inner, effectively the oil of Bearing inner be prevented to let out
Leakage, while water seal is able to use in the filmatic bearing structure of different size, reduces production cost.Such sealing kasaya sets water shutoff
Property it is stronger, substantially improve original structure water inlet, dirt the defects of, avoid occur because bearing water inlet caused by entire rolling line not
The accident that can be worked normally, improves the service life of filmatic bearing.
