Abstract

The utility model relates to a mill oil film bearing single direction limb sealing device, which comprises an oil sealing device and a water sealing device, wherein the feet seal is provided with two single direction feet seal limbs which all face to the pad, on the coupling plane between the two single direction feet seal limbs and he sealing cover, every sealing coupling plane is provided with at least one spiral groove and a refulgence hole under the horizontal line, which effectively prevents lubricating oil leakage, reduces waste and is of no pollution, compacted structure, convenient for installation and increases service life.

Description

The unidirectional pin limb of a kind of filmatic bearing of press seal arrangement
Technical field
The utility model relates to filmatic bearing of press, relates in particular to the unidirectional pin limb of a kind of filmatic bearing of press seal arrangement.
Background technique
At present, be used for the filmatic bearing of hot and cold plate continuous mill, heavy and medium plate mill and wire mill, be mainly used to bear rolling pressure and guarantee milling train low energy consumption stable operation.Existing film bearing seal device is made up of sealing cover, foot-shape sealing, sealing hoop, aluminum ring device, water-stop etc.Sealing cover is loaded onto round rubber and is installed on the bearing support end face by screw, foot-shape sealing is installed sealing hoop and is packed on the sealing surface of sealing cover and hold motion tightly with the roll diameter of axle, aluminum ring device is embedded in the water sealing limb side of foot-shape sealing, water-stop is tightened on the sealing cover end face with brass screw, and plays the effect that cooling liquid is sealed in oil sealing with bearing support, tapered sleeve, lining, roll.Milling train causes the axial float of filmatic bearing in the operation of rolling, affect the sealability of seal arrangement.Existing film bearing seal device also exists leaking of lubricant oil, causes waste and environmental pollution, and influences the deficiencies such as oil film formation of filmatic bearing.
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 and can effectively prevent leaking of lubricant oil, simple and compact for structure, be convenient to install, improve the sealer with assembled filmatic bearing of press in working life.
The unidirectional pin limb of a kind of filmatic bearing of press seal arrangement that the utility model provides, comprise oil-sealing arrangement and water seal arrangement two-part, oil-sealing arrangement has the pin envelope that is installed in sealing cover on the bearing support end face, round rubber, dress sealing hoop by screw, and foot-shape sealing is contained 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; Be characterized in that described pin envelope has two unidirectional pin envelope limbs, pin envelope limb is all towards lining, and on the sealing coupled face of two unidirectional pin envelopes and sealing cover, each sealing coupled face has a spiral chute at least, and is positioned at and has a return port below the horizontal line at least.
The spiral chute of the sealing coupled face of above-described sealing cover is left-handed or dextrorotation, and spiral chute pumps out the less amount of lubrication oil of overflowing, and is back to the bearing support oil trap.
The unidirectional pin limb of a kind of filmatic bearing of press seal arrangement that the utility model provides compared with prior art effectively prevents leaking of lubricant oil, cuts the waste and does not have environmental pollution.Have simple and compact for structurely, be convenient to install, improve advantages such as working life.

Fig. 3 is the sectional view of pin envelope.
Embodiment
Below with reference to accompanying drawing more detailed description embodiment of the present utility model:
Shown in Figure 1, the unidirectional pin limb of a kind of filmatic bearing of press seal arrangement, comprise oil-sealing arrangement and water seal arrangement two-part, oil-sealing arrangement has the pin envelope 5 that is installed in sealing cover 1 on bearing support 4 end faces, round rubber 2, dress sealing hoop 6 by screw 3, and foot-shape sealing is contained 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 4, tapered sleeve 10, lining 11, the roll 12; Water seal arrangement have sealing cover form labyrinth seal aluminum ring device 7, and be fitted in water-stop 8 on the bearing support by bolt and pressure ring 9.
Shown in Figure 2, pin envelope 5 has two unidirectional pin envelope limbs, rear foot envelope is installed all towards lining.
Shown in Figure 3, on the sealing coupled face 101 of the unidirectional pin envelope of two of sealing cover limb 501 and sealing cover, each sealing coupled face has a spiral chute, and is positioned at a return port 102 is arranged below the horizontal line.Spiral chute pumps out the less amount of lubrication oil of overflowing, and is back to the bearing support oil trap.Sealing cover sealing coupled face can adopt the spraying abrasion-proof material, to reduce the wearing and tearing of rubber seal, prolongs receiving a mandate of sealing cover.Its surface roughness is selected to decide according to the difference of the outer fluid medium that stops, general surface roughness is R a=0.4~1.6 μ m.
