Waterproof sound labyrinth seals device with the oxidation dust is sealed effectual, extend bearing life.
Description
Technical field
The utility model belongs to mechanical seal field, particularly relates to a kind of rolling mill bearing waterproof sealing structure.
Background technique
Filmatic bearing, also known as full liquid friction sliding bearing, is made up of critical pieces such as axle journal, bearing shell, Sealing, buffers.In working procedure, the oil between axle journal and bearing shell is infinitely extruded, and produces wedge effect, thus forms oil film.Axle journal and bearing shell two positions with high speed relative movement are separated by oil film, define internal fluid friction, and there is powerful bearing capacity, filmatic bearing is enable to adapt to the working condition of Modern Rolling Mill high speed, heavy duty, and there is the incomparable remarkable advantage of other types of bearings many, thus obtain applying more and more widely on modern large-sized rolling mills.
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.
Bearing support seal designs is unreasonable, sealing effect is poor, cause cooling water, iron scale to enter in a large number in bearing support, cause bearing grease to run off, iron sheet is pressed into, cause load mould, pit, corrosion serious, the problem such as even stuck, causes bearing life seriously to reduce, often occurs bearing loss, bearing wear causes greatly roll to collect together greatly, causes the accident of falling steel.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of rolling mill bearing waterproof sealing structure, solves the problem of sealing effect difference.
The utility model is achieved in that a kind of rolling mill bearing waterproof sealing structure, comprises end cap and shoulder ring, specifically comprises:
Described end cap matches with shoulder ring labyrinth structure,
The end face of described end cap forms the first cavity after exceeding the end face of shoulder ring;
The side of described end cap comprises first protruding and the second projection;
The side of described shoulder ring comprises the 3rd protruding and the 4th projection;
Described 4th projection inserts the first projection with in the second groove convexed to form;
Arrange seal ring in the second cavity formed between the bottom end of described end cap and the bottom end of shoulder ring to seal.
Further, described first projection is right angle with the angle of the cross section end face of the second projection.
Further, described 3rd projection is right-angle structure with the cross section of the end face of the 4th projection.
Further, semi-circular plate is set at described first cavity upper open end.
Further, take on ring in described first cavity water holding ring is set.
Further, two seal ring sealings are set in described second cavity, graphite packing is set between two seal rings.
Compared with prior art, beneficial effect is the utility model:
1) the sound labyrinth gland good sealing effect of waterproof and oxidize soot, extends bearing working life;
2) fundamentally solve rolling mill roll and collect together problems such as causing down steel, steel surface folding;
3) improve bearing working life, reduce bearing purchase cost.
Accompanying drawing explanation
Fig. 1 is the device structure schematic diagram that the utility model embodiment provides.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See Fig. 1, the utility model embodiment provides a kind of rolling mill bearing waterproof sealing structure, sealing structure matches with support roll 12, realize the sealing of support roll 12, comprise end cap 1 to match with the ring labyrinth structure that shoulder ring 4 is formed, the end face 19 of end cap is with on the same parallel surface of end face 14 of shoulder ring, and the end face 19 of end cap forms first cavity 13 with opening higher than after the end face 14 of shoulder ring; The side of end cap 1 comprises the first protruding 8 and second projection 15; What the first protruding 8 and second projection 15 was formed is the structure with first groove 9, first protruding 8 and second projection 15 is right-angle structure, the first groove 9 formed also is right-angle structure, in order to cooperatively interact with the side of end cap, the side of shoulder ring 4 is arranged between the the 3rd protruding 5 and the 4th projection the 7, three protruding 5 and the 4th projection 7, form the second groove 6; 4th projection 7 is inserted in the first protruding 8 and second protruding 15 groove 9 formed; 3rd projection 5, in the first projection 8, forms labyrinth structure, and communicates with the first cavity 13.
In order to prevent the foreign matter such as roll cooling water, iron scale from entering roller-mill bearing, in one embodiment, by the first cavity 13, shoulder ring arranges water holding ring 3.Water holding ring 3 is welded on shoulder ring 4, upper end open.
In an embodiment improved, can arrange a semi-circular plate 2 at the opening of the first cavity 13, semi-circular plate 2 not exclusively hides opening, leaves the gap of one fixed width.
In the structure of static seal, arrange seal ring in the second cavity 18 formed between the bottom end 17 and the bottom end 16 of shoulder ring of end cap to seal, in one embodiment, two seal rings 11 are set in second cavity and seal, graphite packing 10 is set between two seal rings 11.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
