The device is good in sealing effect, simple in structure and convenient to dismantle; and a phenomenon that a bearing is burned-out can be effectively avoided.
Description
Technical field
The present invention relates to a kind of milling train, especially a kind of bearing pedestal seal device of rolling mill roll.
Background technique
In metallurgy industry; in the process of mill milling; the splash everywhere of a large amount of emulsified liquids; between rolling-mill housing in the bearing pedestal seal device of roller; often can enter a large amount of emulsified liquids, cause the loss of lubricating grease in the bearing, thereby cause bearing life sharply to shorten even damage; roller can not be run well, need often to change bearing and the seal arrangement of roller.In order to overcome this problem, at present, mostly adopt oil sealing sealing to stop emulsified liquid to enter in the bearing in the factory, but, this sealing configuration is poorly sealed, can not well stop entering of emulsified liquid, and the roller long time running can cause bearing to burn out, roll wear brings greatly difficulty for production operation and attendant.The existing deficiency of prior art that Here it is.
Summary of the invention
The technical problem to be solved in the present invention is exactly for the existing deficiency of prior art, and a kind of bearing pedestal seal device of rolling mill roll of good sealing effect is provided.
This programme is achieved by the following technical measures: the bearing pedestal seal device of this rolling mill roll comprises the labyrinth sealing inner ring that is set on the roll pins having, is provided with multi-turn rectangular seal chamber I on the outer peripheral surface of sealing inner ring; The outside of sealing inner ring is set with sealing external cover, and the sealing enclosing cover is split type, and the inner side surface of sealing external cover is provided with the rectangular seal chamber II that is complementary with rectangular seal chamber I, is provided with through hole on the sealing external cover; Also be provided with between described bearing support and sealing external cover and the transparent cover that seals inner ring and cooperate, the transparent cover inner ring is equipped with oil sealing; Described sealing external cover is fixedly connected with the bearing support that is installed on the roll end by link with transparent cover.
The end of the above-mentioned sealing inner ring bearing inner race interior with being installed on bearing support is fixedly connected with, and so effectively rigid bearing carries out axially locating to bearing; Simultaneously, also make things convenient for processing and fabricating.
Above-mentioned sealing external cover comprises sealing loam cake and sealing lower cover, and this structural type is beneficial to the quick mounting dismounting, need not dismantle bearing support, can finish the loading and unloading of sealing loam cake and sealing lower cover, and simple to operate, operating efficiency is high.Cover under sealing loam cake and/or the sealing and be provided with through hole, through hole can in time in time throw away the media such as emulsified liquid that enter between sealing inner ring and the sealing external cover.
The beneficial effect of this programme can be learnt according to the narration to such scheme, in the bearing pedestal seal device of this rolling mill roll, (1) the embedded cooperation by multi-turn rectangular seal chamber I and Seal cage II, form multiple-sealed barrier, the media such as emulsified liquid are by a plurality of rectangular seal chamber I and Seal cage II, the media such as emulsified liquid form pressure reduction at tooth top and the bottom land of each rectangular seal chamber I and Seal cage II, thereby increased its flow resistance, the structure of this successive barriers formula, can cushion step by step the pressure of the media such as emulsified liquid, make the pressure level-off that acts between sealing inner ring and the sealing external cover, prevent that the media such as emulsified liquid from entering in the bearing support, thereby reach the effect of effective sealing.(2) oil sealing of installing on the transparent cover, can stop leaking of the interior lubricant grease of bearing on the one hand, can also stop simultaneously the medium such as emulsified liquid to enter in the bearing, labyrinth seal structure between this structure and sealing inner ring and the sealing external cover forms double barrier, can stop entering of the media such as the loss of lubricant grease and emulsified liquid fully.(3) through hole on the sealing external cover can in time throw away the media such as emulsified liquid that enter between sealing inner ring and the sealing external cover, continues to flow to the bearing direction to prevent the media such as emulsified liquid.(4) sealing external cover is split-type structural, and it can realize just can finishing the dismounting of sealing external cover in the situation that do not dismantle bearing support, and disassembling, assembling and replacing is convenient, and operating efficiency is high.This shows, the present invention compared with prior art has good sealing effect, and is simple in structure, and easy accessibility can effectively be stopped the phenomenon that bearing burns out, and the present invention has outstanding substantive distinguishing features and significant progressive, and the beneficial effect of its enforcement also is apparent.
