Description
Technical field
The invention belongs to metallurgical rolling machinery technical fields, and in particular to a kind of colod-application antiseep bearing block dress in roll
It sets.
Background technology
It is to ensure the important means of milling train direct motion and product quality to take spraying cooling measure to roll and rolled band steel.It is cold
In milling train unit production process, generally use emulsion spray cooling, emulsion washes away belt steel surface energy band and walks mill milling
Thermal energy increases lubricating ability, to mitigating roll load, reducing strip thermal deformation, raising cold rolling template quality with fine effect.
But spraying cooling constitutes potential threat again to the water leakage of rolling mill bearing.If roll two end axles bearing waterproof ability is insufficient, spray
The coolant liquid penetrated will leak into inside bearing block, and bearings at both ends mainly uses thin oil lubricant, if being mixed in bearing lubrication system
Enter moisture content, due to oil mixing with water, the quality of lubricating oil can be influenced, reduce lubricant effect, aggravate bearing wear, so as to shorten bearing
Service life.
For example, in some cold rolling mill coupled pickling and tandem mills, since rolling mill bearing block seeps water, bearing lubrication condition is disliked
Change, cause bearing wear serious, after wherein bearing ball denudes the inside of inner-outer sleeve, iron filings are back to hydraulic pressure system with lubricating oil
In system, moisture content in system, iron powder and other impurity contents is caused to severely exceed, oil deterioration, the recycling of poor oil
Large area aggravates bearing wear in turn, and such vicious circle causes bearing service life to be reduced within 2000 hours, with 2
Ten thousand hours work periods are far apart, cause roll operation troubles frequent, influence unit operation, upset normal organization of production,
And bearing purchase cost is high, becomes the conspicuous contradiction of rolling mill production line.
The dual waterproof construction for generally using water seal+oil sealing at present, with simple in structure, the easy advantage of manufacture, but
The injection water high to pressure, impact force is big, antiseepage outlet capacity is poor, if milling train cooling water is penetrated into from roll chock, meeting
Bearing lubrication system oil quality is reduced, influences bearing lubrication effect, aggravation bearing ball wears Internal and external cycle, while Bearing Grinding
The iron powder that damage is fallen is spread with lubricating system, is formed vicious circle, is caused roll bearing to damage, unit disorderly closedown.And it is existing
Have that the dual waterproof construction lip of water seal+oil sealing is wear-resisting and compensation ability is obviously insufficient.
Therefore a kind of Novel seepage water installations are developed, for ensureing roll normal work, improves unit operation rate, reduce axis
Holding purchase cost has realistic meaning.
Invention content

End, and contacted with the end face of main shaft bearing outer-ring, outer water seal is provided between the inner end and roll of the inverted L shape drive end bearing bracket, it is described
Z-shaped channel is formed between inverted L shape drive end bearing bracket and L-type transition sleeve, be disposed with from outside to inside in the Z-shaped channel labyrinth chamber,
Interior water seal and outside framework oil seal.
According to the above technical scheme, the labyrinth chamber is arranged on the vertical passageway in Z-shaped channel, by the first of clearance fit
Groove and the first flange cooperatively form, and one in first groove and the first flange is set on L-type transition sleeve, another
It is set on inverted L shape drive end bearing bracket.
According to the above technical scheme, the interior water seal is mounted in the annular mounting groove on the vertical passageway in Z-shaped channel,
The annular mounting groove is cooperatively formed by the second groove and the second flange of clearance fit, in second groove and the second flange
One be set on L-type transition sleeve, another is set on inverted L shape drive end bearing bracket.
According to the above technical scheme, the interior water seal includes lips radial direction seal ring.
According to the above technical scheme, the outside framework oil seal is mounted in the interconnection in Z-shaped channel.
According to the above technical scheme, the quantity of the outside framework oil seal is multiple, and spacer ring is equipped between adjacent outside framework oil seal.
According to the above technical scheme, gland is installed between the outer end and the inner end of main shaft bearing outer-ring of the inverted L shape drive end bearing bracket.
According to the above technical scheme, O-ring is installed between the inverted L shape drive end bearing bracket and bearing housing.
