Abstract
The utility model relates to colliery digging equipment technical field, disclose a kind of floating sealing structure of continuous miner shipping device reducer, comprise casing, be arranged on the large bevel gear of casing output terminal, large bevel gear outer is provided with floating seal seat outer ring by screw, casing is provided with floating seal seat inner ring by screw, floating seal seat outer ring and floating seal seat inner ring form a support chamber, are provided with fluctuate hermetical ring and O-ring seals in support chamber, thus form floating seal.When floating seal wearing and tearing need to change, only need to back out screw, just can change floating seal seat outer ring, fluctuate hermetical ring, O-ring seals, floating seal seat inner ring.It is long that the utility model avoids the dismounting installation time brought of dismounting large bevel gear, and the defect that labor intensity is large, improves Utilization ratio, simple to operate.
Description
Technical field
The utility model relates to colliery digging equipment technical field, more specifically relates to a kind of floating sealing structure of continuous miner shipping device reducer.
Background technique
Continuous miner is most important big-and-middle-sized colliery extractive equipment, owing to being digging in the narrow tunnel of underground coal mine, hauling operation, its work condition environment very severe.
China Patent No. CN200910175222.6, it is large that name is called that the shipping device reducer of continuous miner discloses a kind of transmission force, is suitable for the shipping device reducer of the continuous miner of rugged environment.Its output terminal is large bevel gear, floating seal is adopted to seal between large bevel gear and casing, digging, hauling operation is carried out in the tunnel that underground coal mine is narrow, floating sealing structure is herein owing to lubricating insufficient or entering foreign object and easily cause sealing minute surface on floating seal or O RunddichtringO to damage, thus make seal failure, need to change in time.Need during replacing first to be disassembled in the bearing of casing by large bevel gear, then change floating seal, and then large bevel gear is reorientated installation, change floating seal so consuming time longer, reduce Utilization ratio, labor intensity is large, and replacement operation is complicated.
Model utility content
The utility model, for overcoming above-mentioned deficiency of the prior art, provides a kind of floating sealing structure being convenient to the continuous miner shipping device reducer changing floating seal.
The utility model is achieved through the following technical solutions above-mentioned purpose.
A kind of floating sealing structure of continuous miner shipping device reducer, comprise casing and the large bevel gear being arranged on casing output terminal, large bevel gear outer is provided with floating seal seat outer ring by screw, casing is provided with floating seal seat inner ring by screw, floating seal seat outer ring and floating seal seat inner ring form a support chamber, be provided with fluctuate hermetical ring and O-ring seals in support chamber, thus form floating seal.
When floating seal occurs that wearing and tearing need to change, only need to back out screw, floating seal seat outer ring is pulled down from large bevel gear, just can change floating seal seat outer ring, fluctuate hermetical ring or O-ring seals; If floating seal is longer for service time, floating seal forms the reason such as break-in face or wearing and tearing corrosion and causes part replacing cannot realize sealing, when needing integral replacing, also only need to back out screw again, floating seal seat inner ring is pulled down from casing and carries out integral replacing.Doing so avoids the defect that dismounting installation time is long, labor intensity is large that dismounting large bevel gear brings, improve Utilization ratio, simple to operate.
Be provided with O shape between above-mentioned floating seal seat inner ring and casing to enclose, prevent the lubricant oil in casing from oozing out from the junction plane of casing and floating seal seat inner ring, improve sealing effect further.
Be provided with O shape between above-mentioned floating seal seat outer ring and large bevel gear to enclose, prevent the lubricant oil in casing from oozing out from the junction plane of large bevel gear and floating seal seat outer ring, improve sealing effect further.
Be provided with wear-resistant sleeve between above-mentioned floating seal seat outer ring and casing, to realize mechanical seal, its long service life, can prevent foreign object from entering in support chamber to avoid causing unnecessary erosion corrosion etc.
The utility model compared with prior art mainly has following beneficial effect: avoid the dismounting installation time brought of dismounting large bevel gear long, the defect that labor intensity is large, improves Utilization ratio, simple to operate; Prevent the lubricant oil in casing from oozing out from rigid junction plane, improve sealing effect; Adopt wear-resistant sleeve to realize mechanical seal, increase the service life.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the utility model embodiment.
Fig. 2 is the partial enlarged drawing at K place in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent.

Embodiment:
As shown in Figure 1, a kind of floating sealing structure of continuous miner shipping device reducer, comprise casing 1, be arranged on the large bevel gear 2 of casing 1 output terminal, the outer (namely large bevel gear 2 exposes the outer ring of casing 1 part) of large bevel gear 2 is provided with floating seal seat outer ring 3 by screw, casing 1 is provided with floating seal seat inner ring 4 by screw, floating seal seat outer ring 3 and floating seal seat inner ring 4 form a support chamber, be provided with fluctuate hermetical ring 5 and O-ring seals 6 in support chamber, thus form floating seal.
As shown in Figure 2, the junction plane place of the present embodiment between floating seal seat inner ring 4 and casing 1 is provided with O shape and encloses 7, prevents the lubricant oil in casing 1 from oozing out from the junction plane of casing 1 and floating seal seat inner ring 4, improves sealing effect further.
The junction plane place of the present embodiment between floating seal seat outer ring 3 and large bevel gear 2 is provided with O shape and encloses 8, prevents the lubricant oil in casing 1 from oozing out from the junction plane of large bevel gear 2 and floating seal seat outer ring 3, improves sealing effect further.
The present embodiment is provided with wear-resistant sleeve 9 between floating seal seat outer ring 3 and casing 1, wear-resistant sleeve 9 is positioned at the radial outside of support chamber, to realize mechanical seal, its long service life, and can prevent foreign object from entering in support chamber to avoid causing unnecessary erosion corrosion etc.
These are only a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, all the utility model that utilizes conceive the insubstantial modifications made the utility model, all fall within protection domain of the present utility model.
