Description
Technical field
The utility model relates to filmatic bearing of press, more specifically to a kind of sealer with assembled filmatic bearing of press.
Background technique
At present, be used for cold and hot rolling mill,, slab and wire mill filmatic bearing.Be mainly used to bear rolling pressure and guarantee milling train low energy consumption stable operation.The sealability of seal arrangement is very big to the formation influence of pressure oil film in the filmatic bearing, leaking of lubricant oil causes waste and environmental pollution, cooling liquid, dirt enter bearing inside, can cause phenomenons such as lubricated oil descends, part gets rusty to take place, and influence the oil film formation of filmatic bearing.The axial float of the filmatic bearing that milling train causes in the operation of rolling can produce harmful effect to sealing configuration.Existing film bearing seal device as shown in Figure 1, is made up of sealing cover, pin envelope, sealing hoop, aluminum ring device, water-stop etc.Sealing cover 1 is loaded onto round rubber 2 and is installed on bearing support 4 end faces by screw 3, pin envelope 5 is installed sealing hoop 6 and is packed on the sealing surface of sealing cover and hold motion tightly with the roll diameter of axle, aluminum ring device 7 is embedded in the water sealing limb side of foot-shape sealing, water-stop 8 usefulness brass screws 9 are tightened on the sealing cover end face, play the effect that cooling liquid is sealed in oil sealing with bearing support 4, tapered sleeve 10, lining 11, roll 12.The deficiency that is fixed on the water seal existence on the sealing cover in the existing film bearing seal device has the following aspects:
1, is the distance that can increase or reduce sealing limb and roll end face, thereby changes sealing limb decrement, influence sealing effect, cause a large amount of extraneous media to enter bearing;
2, be that the roll end face uses long-time back to produce corrosion and groove because of cooling liquid and wearing and tearing, influence the working life of sealing effect and sealing more;
3, be if going into to soak and can't discharging of cooling liquid takes place.
Summary of the invention
The utility model proposes to improve with regard to the problem and shortage that exists in the above-mentioned existing filmatic bearing of press seal arrangement technology, provide a kind of can effectively preventing to cause dirts such as cooling liquid, iron scale to immerse filmatic bearing of press to axial float, simple and compact for structure, be convenient to install, improve the sealer with assembled filmatic bearing of press in working life.
A kind of sealer with assembled filmatic bearing of press that the utility model provides, comprise oil-sealing arrangement and water seal arrangement two-part, oil-sealing arrangement has the sealing that is installed in sealing cover on the bearing support end face, round rubber, dress sealing hoop by screw, and pin is encapsulated on the sealing surface of sealing cover and with the roll diameter of axle and holds motion tightly; Water seal arrangement is loaded between bearing support, tapered sleeve, lining, the roll; Water seal arrangement has an aluminum ring device and water-stop; Be characterized in that described water-stop is that seal combination by one or several gaps, end face, centrifugal, labyrinth and backflow form forms; Water-stop is fixed on the end face of roll or support roll and with sealing cover and relatively rotates, and is the face of being sealed and matched between water-stop and the sealing cover.
Above-mentioned water-stop contains the retaining ring that is fixed on roll or the support roll, is loaded on the pressure ring sealing on the retaining ring; The outer ring portion of pressure ring sealing constitutes a clearance seal with the cylindrical of sealing cover; In the pressure ring sealing, be provided with the pin envelope, and constitute sealing with the end face of sealing cover; And also constitute a clearance seal with sealing cover upper inner ring face at the interior ring of pressure ring sealing.
Above-mentioned water-stop contains the sealing retaining ring that is fixed on roll or the support roll, is loaded on the pressure ring sealing on the retaining ring; The outer ring portion of pressure ring sealing constitutes a clearance seal with the cylindrical of sealing cover; And also constitute a clearance seal with sealing cover upper inner ring face at the interior ring of pressure ring sealing; A cooling liquid sealing that matches with sealing cover upper inner ring face also is housed in retaining ring.
A kind of sealer with assembled filmatic bearing of press of the present utility model compared with prior art, wherein water seal arrangement has stopped a large amount of cooling liquids and dirt with clearance seal as the first road cooling liquid sealing, end face seal is retracted to the inside, the sealing cover that uses stupalith to make has prevented from the impact of cooling liquid and has prevented to add huge influence to end face seal because of the corrosion that cooling liquid causes effectively; The spiral chute of setting up one clearance seal, radial seal, fitted seal lid again prevents that more effectively cooling liquid from entering, even a spot of infiltration is arranged, by the multiple discharge through-hole of pressure ring sealing, retaining ring, sealing cover cooling liquid is discharged.
The substantive distinguishing features and the obvious improvement of a kind of sealer with assembled filmatic bearing of press of the present utility model are: solved because of the roll axial float causes cooling liquid, dirt and entered filmatic bearing of press inside, caused part to get rusty effectively, lubricated oil descends, and influence oil film formation etc. for a long time since be difficult to overcome problem, and have simple and compact for structure, be convenient to advantages such as raising in working life are installed.
