Abstract
The invention relates to an anti-oil-overflow bearing seal structure of a roller. The anti-oil-overflow bearing seal structure comprises the roller, wherein the roller is sleeved with a bearing, two oil retainers and two bearing covers; an oil storage bin is arranged in the inner side of the side wall of each bearing cover; an oil inlet is formed in the oil storage bin; the oil storage bin and the inside of the bearing cover are communicated through the oil inlet; the outer edge of the side wall of each oil retainer extends to the oil inlet; an oil outlet is also formed in the oil storage bin; and the oil storage bin and the outside of the bearing cover are communicated through the oil outlet. According to the anti-oil-overflow bearing seal structure of the roller, the oil storage bin is arranged in the inner side of the side wall of each bearing cover; the outer edge of the side wall of each oil retainer is aligned with the oil inlet of the oil storage bin; when the roller runs with a high speed, the oil on the oil retainers can be dumped into the oil storage bin and lubricating oil is further prevented from overflowing out the space between each bearing cover and the roller; a bulge for retaining oil is formed in the end part of the side wall of each bearing cover and extends towards the direction of the bearing, so that the overflowed lubricating oil can flow to each oil retainer to the greatest extend and then be dumped into the oil storage bin; and the structure is simple and the effect is remarkable.
Description
Technical field
The present invention relates to high speed hot rolling device domain technical field, especially a kind of roll preventing oil spill bearing seal knot
Structure.
Background technology
Hot-rolling mill belongs to hot worked rolling equipment.Hot rolling production efficiency is high, and scale is big, consuming little energy, low cost, machine
Tool, high degree of automation, are suitable to the continuous production of high-volume, are most important metal-pressed machine modes.Hot rolling is because during processing
The resistance of deformation of metal is low and plasticity is good and be widely used.
In general the bearing being adopted on hot-rolling mill has reasonable rigidity and lubricity, is unlikely to deform, and has
Good service life.When existing bearing is run with roll cooperation, need using lubricating oil, bearing to be lubricated, but profit
Lubricating oil easily overflows from bearing cap with the gap of roll cooperation, causes the leakage of lubricating oil, thus affecting the sealing of bearing.
Content of the invention
The technical problem to be solved in the present invention is: in order to prevent seam between bearing cap and roll for the lubricating oil in bearing
Overflow in gap, the invention provides a kind of roll preventing oil spill bearing seal structure, one storage is set in bearing cap inside sidewalls
Bunker, and oil scraper ring side wall outer is directed at oil storage cabin oil-in, can be by oil scraper ring when roll runs up
Oil gets rid of under the action of the centrifugal into oil storage cabin, has organized lubricating oil to overflow between bearing cap and roll further, structure is simple, effect
Fruit is notable.
The technical solution adopted for the present invention to solve the technical problems is: a kind of roll preventing oil spill bearing seal structure,
Including roll, roll is arranged with bearing, two oil scraper rings and two bearing caps, bearing be between two oil scraper rings and and
Oil scraper ring is fixedly installed on roll jointly, and two bearing caps are located at outside two oil scraper rings, and two bearing caps pass through bearing outer ring admittedly
Surely it is tightly connected, described bearing cap inside sidewalls are provided with oil storage cabin, and described oil storage cabin is provided with oil-in, described oil-in is by oil storage
Storehouse connects with bearing cap, and described oil scraper ring edge sidewalls extend at oil-in, and described oil storage cabin is additionally provided with oil-out, institute
State oil-out to connect oil storage cabin with outside bearing cap.
In order to greatest extent the lubricating oil of spilling be transported in oil storage cabin, described bearing cap side wall ends are provided with a use
In the projection of gear oil, described projection extends to bearing direction.
Preferably, being provided with the folded ring of sealing between described bearing cap and roll.
The invention has the beneficial effects as follows: the invention provides a kind of roll preventing oil spill bearing seal structure, in bearing cap
Inside sidewalls arrange an oil storage cabin, and oil scraper ring side wall outer are directed at oil storage cabin oil-in, when roll runs up
Time can be got rid of the oil on oil scraper ring into oil storage cabin under the action of the centrifugal, organized lubricating oil further from bearing cap and roll it
Between overflow, and bearing cap side wall ends be provided with one to bearing direction extend, for keep off oil projection, can to greatest extent by
The lubricating oil overflowing flow to oil scraper ring, and then gets rid of into oil storage cabin, and structure is simple, effect is significant.
