A plurality of dissection formula parts and well spacer sleeve constitute, and be a plurality of that sealing device is used with online isolation of distributor box to main shaft, by the suit on the distributor box output subdivision formula part includes disc, labyrinth ring and clamp ring, the fixed suit of labyrinth ring is on the bearing spacer ring of distributor box output, the clamp ring lock ring is at labyrinth ring's both ends, still be provided with the disc in the labyrinth ring, labyrinth ring and disc cooperate, and to constitute labyrinth seals vice, well spacer sleeve suit is on the clamp ring. The utility model discloses sealing device is used with online isolation of distributor box to main shaft need not dismantle under the original tooth cover and the spacer ring circumstances, and it is vice to adopt a formula of cuing open to assemble with loading onto labyrinth seals, guarantees not oil leakage, has realized that the old and new lubricating system's safety is kept apart fast, has made things convenient for transformation work greatly, has practiced thrift the transformation expense, has guaranteed normal production plan.
Description
Technical field
This utility model relates to milling train rotating mechanism seal member, particularly relates to a kind of online isolation sealing device.
Background technology
The composition of finish rolling mill main drive system is made up of F1-F5 main gear reducer, F1-F7 distribution gear case etc..The lubricating system used is centralized cycle mode, a single lubricating system provide centralized cycle lubrication.Each casing is configured with single oil-feed drainback passage, then by arm and system superintendent UNICOM.The at present lubrication system of finish rolling mill main drive system, water inlet that in system, any point causes or pollution, all will affect the lubricant effect of whole system.
In order to solve main shaft water inlet problem, need to isolate the lubrication of main shaft with legacy system.Existing isolating device must remove F1-F7 distributor box output end tooth set and bearing spacer online.The distributor box of 7 frames wants to complete to change spacer ring within the time period of annual overhaul, and workload is very big, has been difficult to, can affect normal manufacturing schedule；And dismount work and also can bring installation accuracy problem, cause potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of main shaft and distributor box isolation sealing device online in the case of need not dismantle original distributor box tooth set and spacer ring, employing is cutd open part formula and is assembled and add that to load onto labyrinth seal secondary, ensure not alter oil, achieve the isolation safely and fast of the old and new's lubricating system, solve and prior art needs overall pulling down, engineering time is long, the defect that construction risk is high.
This utility model is achieved in that a kind of main shaft is constituted with distributor box isolation sealing device online, several dissection type parts and middle spacer sleeve by being sleeved on distributor box outfan, and some described dissection type parts include disc, labyrinth ring and hold-down ring；Described labyrinth ring is fixedly set on the bearing spacer of distributor box outfan, and described hold-down ring lock ring is at the two ends of labyrinth ring；Being additionally provided with disc in described labyrinth ring, labyrinth ring matches with disc and constitutes labyrinth seal pair, and described middle spacer sleeve is sleeved on hold-down ring.
The end of described middle spacer sleeve has cover body, described cover body to be split type structure also by Flange joint.
Offer access hole on described cover body, equipped with cover plate on access hole, between described cover plate and cover body, be provided with sealing gasket.
The top of described middle spacer sleeve is additionally provided with hanger.
The bottom of described middle spacer sleeve is provided with oil-recovery tank.
This utility model main shaft and distributor box isolation sealing device online are in the case of need not dismantle original tooth set and spacer ring, employing is cutd open part formula and is assembled and add that to load onto labyrinth seal secondary, ensure not alter oil, achieve the isolation safely and fast of the old and new's lubricating system, greatly facilitate retrofit work, save improvement expenses, it is ensured that the normal production schedule.

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further.Should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model.In addition, it is to be understood that after having read the content of this utility model statement, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally.
Embodiment 1
As shown in Figure 1, 2, use sealing device isolated online by a kind of main shaft with distributor box, and several dissection type parts and middle spacer sleeve 3 by being sleeved on distributor box outfan 1 are constituted, and some described dissection type parts include labyrinth ring 4, disc 5 and hold-down ring 6；Described labyrinth ring 4 is fixedly set on the bearing spacer of distributor box outfan 1, and described hold-down ring 6 lock ring is at the two ends of labyrinth ring 4；Being additionally provided with disc 5 in described labyrinth ring 4, labyrinth ring 4 matches with disc 5 and constitutes labyrinth seal pair, and described middle spacer sleeve 3 is sleeved on hold-down ring 6, in installation process, after disc 5 is installed and put in place, is finally welded as a whole by the disc 5 of subdivision；In the present embodiment, it is contemplated that install fixing factor, the end of described middle spacer sleeve 3 connects also by flange 7 cover body 2, and described cover body 2 is split type structure；Offer access hole on described cover body 2, equipped with cover plate 10 on access hole, between described cover plate 10 and cover body 2, be provided with sealing gasket 11.
As it is shown on figure 3, the bolt hole that described disc 5 utilizes original distributor box outfan 1 end face is installed so that it is the composition that matches with labyrinth ring 4 labyrinth seal is secondary, it is achieved that the isolation of the old and new's lubricating system；
As shown in Figure 4, the splicing seam crossing of the labyrinth ring 4 of described dissection type is with being welded and fixed connection；Labyrinth ring 4 is to cut subdivision by line again after overall processing, how much understands some deformation, and must assure that after installing and can not alter oil, so needing hold-down ring 6 to compress after cutting on line；Described hold-down ring 6 diameter of bore is necessarily less than labyrinth ring 4 external diameter installed additional, and to ensure certain rigidity, does not so have the effect of tightening up；
As shown in Figure 5, the top of described middle spacer sleeve 3 is additionally provided with hanger 8, the bottom of described middle spacer sleeve 3 is provided with oil-recovery tank 9, utilizes original spill port bottom distributor box outfan lower bearing, makes the lubricating oil of original system be returned in distributor box casing by the oil duct drain newly installing labyrinth seal additional secondary.
