Abstract
The invention discloses an oil film bearing sealing part which comprises a bushing, a taper sleeve and a roller. The roller is sleeved with the taper sleeve, and the taper sleeve is sleeved with the bushing. The oil film bearing sealing part further comprises a sealing baffle, an aluminum ring device, an outer sealing ring and an oil tank. One side of the oil tank is adjacent to the bushing, and the other side of the oil tank is connected with a sealing cover. An oil collecting groove is formed in the face, opposite to the sealing cover, of the oil tank and a filter screen is arranged at an inlet of the oil tank. The sealing baffle is located between the sealing cover and the roller and is provided with five sealing lips, wherein the sealing lip D and the sealing lip E serve as the water sealing lip and the oil sealing lip of the sealing cover respectively. The outer sealing ring is connected with the sealing cover, and the two ends of the aluminum ring device are connected with the outer sealing ring and the sealing baffle respectively. The surface of the sealing cover is coated with ceramics. Through the structure, blocking which happens in the oil backflow process can be avoided, abrasion of the sealing lips is reduced, the sealing capacity is improved, and the service life of the sealing baffle is prolonged.
Description
Technical field
The present invention relates to field of bearings, be specifically related to filmatic bearing Sealing.
Background technique
The sealing system of filmatic bearing is the critical component of filmatic bearing, has dual function: prevent the lubricant oil in bearing cavity from leaking on the one hand, make lubricant oil return pumping plant from casing, ensures to form continuously oil film; Prevent from the other hand, in extraneous cooling water, ROLLING OIL (emulsified liquid) and iron filings, dust and other impurities infiltration bearing cavity, maintaining the normal operation of bearing.If seal failure, external impurities can be caused to invade, make lubricant pollution aging, reduce the filmatic bearing life-span; Also can cause oil leak in cavity, not only cause the consumption of large gauging to waste, and fluid can throw away along the tangent direction of roller rotational, splashes to the steel band, the surface of steel plate that roll out, pollutes, increase annealing difficulty, affect steel strip surface quality.Filmatic bearing Sealing of today in use seal lip easily weares and teares, and affects sealability, reduces the working life of sealing baffle.Easily produce impurity in the fluid collected in filmatic bearing Sealing in addition, easily block in reflux course, impact normally works.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, provide filmatic bearing Sealing, this structure can avoid fluid to block in reflux course, alleviates seal lip wearing and tearing, improves sealability, extend the working life of sealing baffle.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: filmatic bearing Sealing, comprise lining, tapered sleeve and bundle roller, tapered sleeve is enclosed within roll, and lining is enclosed within outside tapered sleeve, also comprises sealing baffle, aluminum ring device, sealing outer shroud and fuel tank, side and the lining of described fuel tank are adjacent, the opposite side of fuel tank is connected with sealing cover, and the opposing side of fuel tank and sealing cover arranges oil trap, arranges filter screen in the ingress of fuel tank; Described sealing baffle is at sealing cover and prick between roller, sealing baffle arranges five seal lips, seal lip D wherein and seal lip E is respectively as the water shutoff lip of sealing cover and oil sealing lip, and a seal lip in three sealing lips remaining on sealing baffle is then as throwing oily limb; Described sealing outer shroud connects sealing cover, and aluminum ring device two ends connect sealing outer shroud and sealing baffle respectively; Described sealing cover surface spraying has pottery.
Throw oily limb when sealing baffle rotary work, the ROLLING OIL that tapered sleeve and sleeve clearances gush to be got rid of in oil trap, and fluid is flow in fuel tank along spill port reflux again, play the effect of sealing fluid.The filter screen arranged at fuel tank inlet place can stop to fall the impurity in fluid, and then refluxes, and avoids impurity in reflux course, occur situation about blocking.Center flange and the sealing lip tactile with its two shoulder grafting of sealing cover define mazy type barrier, improve sealability.The right part of sealing outer shroud, aluminum ring device and sealing cover forms twice water shutoff defence line, stops the inflow of a large amount of cooling liquid and the intrusion of impurity, and the cooling liquid entered on a small quantity is discharged by the lower fluting of sealing outer shroud.At the pottery of sealing cover surface spraying, the wearing and tearing of contact seal lip can be alleviated, improve sealability, extend the working life of sealing baffle.
The abutting end of described sealing baffle and sealing cover also arranges sealing hoop.Sealing hoop the stability that can increase sealing baffle is set.
The surface of contact of the seal lip D on described sealing baffle and seal lip E and sealing cover is arc shaped surface.Strengthen lip followability, avoid occurring that leakage of oil situation occurs.
Described sealing baffle also arranges sealing steel band.Sealing steel band, for being enclosed within the waist of journal packing, prevents the centrifugal force of axle journal under High Rotation Speed effect to the change of its shape and size.
Compared with prior art, the invention has the beneficial effects as follows:
1, the filter screen arranged at fuel tank inlet place can stop to fall the impurity in fluid, and then refluxes, and avoids impurity in reflux course, occur situation about blocking.
2, at the pottery of sealing cover surface spraying, the wearing and tearing of contact seal lip can be alleviated, improve sealability, extend the working life of sealing baffle.
The surface of contact of the seal lip D 3, on sealing baffle and seal lip E and sealing cover is arc shaped surface, strengthens lip followability, avoids occurring that leakage of oil situation occurs.
4, sealing steel band for being enclosed within the waist of journal packing, preventing the centrifugal force of axle journal under High Rotation Speed effect to the change of its shape and size.
