Abstract
The utility model discloses a rolling mill frame roller bearing seat sealing device, including passing through lid and J type oil blanket, pass through the lid section and be L shape, be equipped with the seal groove on passing through the lid inner wall, the seal groove is embedded to have the sealing washer, passes through to cover the diapire inboard and opens there is the oil blanket groove, and the oil blanket inslot is embedded to have J type oil blanket, passes through to cover the lateral wall inboard and opens there is the draw-in groove, and Z shape sealing ring one side is stretched out the end and is installed in passing through the lid draw-in groove, and another end that stretches out of sealing ring and passes through to cover diapire. An oil storage cavity I is formed between the sealing ring and the transparent cover, and an oil storage cavity II is formed between the sealing ring and the inner end face of the bearing sleeve, so that external water can be prevented from entering the bearing seat, the lubricating condition of the bearing is improved, the service life of the bearing is prolonged, and the cost of spare parts and the maintenance workload are reduced. Meanwhile, a large amount of waste plates generated by the abnormal operation of the frame roller can be avoided, and the operation rate of the rolling mill is improved.
Description
Technical field
The utility model belongs to mechanical equipment of steel rolling field, particularly a kind of sealing device of heavy and medium plate mill breast roll bearing block.
Background technology
Breast roll is the important component part of heavy and medium plate mill, stings steel, when throwing steel, especially when discount appears in rolled piece, breast roll is subject to great shock loading, very easily causes breast roll to damage at milling train, and wherein occurs that maximum is the damage of bearing.
The seal form of breast roll bearing block, body of roll side adopts shoulder ring and the mechanical seal of transparent cover composition labyrinth type, adopts entire terminal cover to add sealing gasket sealing, adopt size transparent cover to form mechanical seal outside transmission side outside fore side.Certain Heavy Plate Plant breast roll adopts three to connect hole bearing block and three colored rollers are assembled into an entirety, and its breast roll bearing damage is frequent, and cause roller stuck, during rolling, steel plate cannot pass through smoothly in transport process, produces a large amount of useless plate and surface tear defect.This breast roll drive roll master end outer side seal form is: install a grease proofing J type oil sealing in bearing block transparent cover, form sealing surface, leak outside to prevent oil with spline housing outer surface.But the sealing of this form can not prevent the refraction of outside milling train water under high pressure from impacting, bearing block water inlet is serious, and bearing life is short, and breast roll fault rate is high, and maintenance cost is high, has a strong impact on rolling rhythm simultaneously.
Summary of the invention
The utility model provides a kind of roll mill bearing pedestal seal device, is intended to prevent water inlet in bearing, thus extends bearing service life, reduces breast roll changing number of times, reduces spare part expense and maintenance time.
For this reason, the solution that the utility model is taked is:
A kind of roll mill bearing pedestal seal device, comprise transparent cover and J type oil sealing, it is characterized in that, described transparent cover section is L shape, transparent cover inwall is provided with seal groove, seal groove is embedded with sealing ring, transparent cover inside bottom wall has oil seal groove, oil seal groove is embedded with J type oil sealing, transparent cover inside sidewalls has draw-in groove, Z-shaped sealing ring side external part is arranged in transparent cover draw-in groove, another external part of sealing ring and transparent cover diapire front end lean in the both sides of bearing holder (housing, cover) inner face respectively, trapped fuel chamber I is formed between sealing ring and transparent cover, trapped fuel chamber II is formed between sealing ring and bearing holder (housing, cover) inner face.
The beneficial effects of the utility model are:
Owing to defining trapped fuel chamber I and trapped fuel chamber II, outside water can be stoped to enter bearing block inside, improve the lubricating condition of bearing, extend bearing service life, annual reduce change before and after breast roll each a set of, reduce spare part expense and maintenance load.Meanwhile, avoid a large amount of useless plate produced because breast roll can not normally run, improve the operating rate of milling train.
Accompanying drawing explanation
Fig. 1 is breast roll bearing pedestal seal device profile.
In figure: spline housing 1, sealing ring 2, transparent cover 3, bearing block 4, J type oil sealing 5, sealing ring 6, breast roll 7, trapped fuel chamber I 8, trapped fuel chamber II 9, bearing 10.
Detailed description of the invention
As seen from Figure 1, be inlaid with bearing 10 in bearing block 4, breast roll 7 is arranged in bearing 10, and the inner side of breast roll 7 is provided with spline housing 1.The utility model roll mill bearing pedestal seal device, on the basis of former transparent cover 3 and J type oil sealing 5, one is the shape changing transparent cover 3, L shape is changed into by annular transparent cover 3 section, transparent cover 3 inwall and spline housing 1 joint face have set up one and has enclosed seal groove, seal groove is embedded with sealing ring 2; Transparent cover 3 inside bottom wall and sealing ring 6 contact surface have oil seal groove, and oil seal groove is embedded with J type oil sealing 5.Two is set up Z-shaped sealing ring 6, and increase a circle draw-in groove in transparent cover 3 inside sidewalls, sealing ring 6 side external part is arranged in the draw-in groove of transparent cover 3, and another external part of sealing ring 6 and the diapire front end of transparent cover 3 lean the both sides of the bearing holder (housing, cover) inner face at bearing 10 respectively.Determined by the features of shape of L shape transparent cover 3 with Z-shaped sealing ring 6, between sealing ring 6 and transparent cover 3, formed a trapped fuel chamber I 8, between sealing ring 6 and bearing holder (housing, cover) inner face, also formed another trapped fuel chamber II 9 simultaneously.
