Abstract
The invention relates to a locomotive gear box seal device which comprises fixed seal rings and movable seal rings. The fixed seal rings are fixed on a gear box. The movable seal rings are fixed on a gear. The axial section radial teeth of the fixed seal rings and the movable seal rings are staggered at intervals, and the axial teeth of adjacent radial teeth are staggered at intervals. Multiple fixed seal rings and movable seal rings are stacked through fixing bolts and positioning pins. The locomotive gear box seal device is free of contact abrasion, safe and reliable in sealing, and convenient and simple to assemble and disassemble, influence of wheel vibration on sealing is avoided, and machining, assembling, maintenance and lubricant backflow problems and the like of multistage sealing are solved.
Description
Technical field
The present invention relates to a kind of locomotive gear box seal device, belong to railway locomotive technical field.
Background technique
Existing installing locomotive gear cases sealing mainly contains two kinds of forms: contact seal or labyrinth sealing.
Contact seal, exactly as using felt or macromolecular material to be in contact with one another between the gear housing of fixed block and the gear of revolving part or wheel, reach the seal action to casing, be relatively typically east wind 4B locomotive and Shaoshan 4 electric locomotives of current domestic use.This mode initial stage still can reach seal action, but slightly long sealing material of time will lose seal action because of wearing and tearing, causes leakage of oil.In order to guarantee normal utilization, have to repeatedly add lubricant oil or lubricant oil is changed into grease, cause a large amount of oil product wastes, environment is also polluted.(< < SS4 modified locomotive gear-box assembly technology affects > >, rolling stock technique, the 6th phase in 2006 to leakage of oil)
Labyrinth sealing is to use labyrinth clearance to form when rotated dynamic eddy current, to forming seal action inside and outside gear housing.The gear-box that relatively more typical application is the east wind 4D series cab of domestic use.This mode requires labyrinth clearance relatively stable, but when locomotive operation, due to the vibrations of wheel, can make labyrinth seal clearance change, and causes oil seepage, and the oil product of seepage also can cause the pollution of locomotive itself and the pollution of environment with rotation of wheel.
Summary of the invention
Object of the present invention overcomes the deficiency of above-mentioned prior art exactly, and a kind of locomotive gear box seal device is provided.
The object of the present invention is achieved like this: a kind of locomotive gear box seal device, by the dynamic seal ring of determining seal ring and being fixed on gear being fixed on gear-box, formed, describedly determine seal ring and dynamic seal ring axial section and be that between radial teeth, gap is staggered mutually, it is characterized in that the described adjacent radial between cog of determine seal ring and dynamic seal ring axial section is also between axial tooth mutual gap staggered.
In order to realize better object of the present invention, overpay described fixed and moving seal ring and superpose by fixing bolt and locating stud.
The solution of the present invention, take into full account the running state of locomotive, particularly locomotive high speed operation space-time gas phase impact on sealing configuration on the wheel wind of the mobile formation of gear-box negative pressure, there is no contact wearing and tearing, avoided the impact of unsteadiness of wheels on sealing, sealingly secure is reliable, and assembling, convenient disassembly is simple, solved the problems such as multi-stage sealed processing, assembling, Maintenance and Repair and lubricant oil backflow.
Accompanying drawing explanation
Fig. 1 is the locomotive gear box seal device axial section principle schematic of the embodiment of the present invention.
In figure, be labeled as: 1-dynamic seal ring one, 2-dynamic seal ring two, 3-determines seal ring one, 4-seals fixing bolt surely, tri-grades of spill ports of 5-, 6-secondary spill port, 7-one-level spill port, 8-determines seal ring two, 9-gear, 10-bearing, 11-locating stud, 12-motive sealing fixing bolt, 13-gear-box, 14-dynamic seal ring radial teeth, 15-dynamic seal ring axial tooth, 16-determines seal ring radial teeth, and 17-determines seal ring axial tooth.
Embodiment
For making object, technological scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment who obtains under creative work prerequisite, belong to the scope of protection of the invention.
Referring to Fig. 1, the locomotive gear box seal device of the present embodiment, determines seal ring 1 and determines seal ring 28 to be fixed on gear-box 13 by determining sealing fixing bolt 4.Dynamic seal ring 1 and dynamic seal ring 22 are fixed on gear 9 by motive sealing fixing bolt 12, determine 14 mutual gaps of seal ring radial teeth 16 and dynamic seal ring radial teeth staggered, on adjacent radial tooth determine seal ring axial tooth 17 and 15 mutual gaps of dynamic seal ring axial tooth are staggered.
From in gear-box 13 bodies outwards the first order be sealed into radial seal, by the radial teeth 16 of determining on seal ring 28, utilize less gap and sufficient axial length to coordinate dynamic seal ring 22 flat segments to realize, most lubricant oil is sealed, and guaranteeing has enough oil lubrication bearings in bottom; Because be clearance seal, must there is a certain amount of lubricant oil to enter between the first secondary seal, for guaranteeing that lubricant oil gets back in casing, determining on seal ring 28, to reserve return opening 7.
Second level sealing is axial seal, between the axial tooth on the adjacent radial tooth of seal ring 1 and dynamic seal ring 22, coordinate by determining, guarantee that lubricant oil is in axial sealing, now only there is minute quantity lubricant oil to enter between the two or three grade of sealing, determining on seal ring 1, to reserve spill port 6, solved labyrinth seal clearance and changed, the oil seepage problem causing.
Third level sealing is dust sealing, determines to coordinate between the axial tooth on the adjacent radial tooth of seal ring 1 and dynamic seal ring 1, prevents that dust foreign matter from entering pollution lubricating oil.
Reliable for guaranteeing the location of dynamic seal ring 1 and dynamic seal ring 22, locating stud 11 has also been installed between the two.
Finally it should be noted that: above embodiment only, in order to technological scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or part technical characteristics is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technological scheme.
Claims (2)
1. a locomotive gear box seal device, by the dynamic seal ring of determining seal ring and being fixed on gear being fixed on gear-box, formed, describedly determine seal ring and dynamic seal ring axial section and be that between radial teeth, gap is staggered mutually, it is characterized in that describedly determine seal ring and dynamic seal ring axial section adjacent radial between cog to be also between axial tooth mutual gap staggered.
