Abstract
The utility model provides an outwards-extending shaft end combined seal which comprises an upper half oil collecting hood, a lower half oil collecting hood, a radial oil slinger and a labyrinth ring. The upper half oil collecting hood and the lower half oil collecting hood are connected oppositely to form an oil collecting hood which is arranged on a rotating shaft in an annular sleeved mode, one end of the radial oil slinger is arranged in the oil collecting hood and arranged on the rotating shaft in an annular sleeved mode, a sealing piece is arranged on the outer circumference face of the radial oil slinger, the sealing piece and the oil collecting hood form a non-contact radial labyrinth seal, the labyrinth ring is arranged at one end, protruding out of the oil collecting hood, of the radial oil slinger in an annular sleeved mode, and the labyrinth ring and an axial annular groove in the outer end face of the oil collecting hood form a non-contact axial labyrinth seal. The non-contact radial labyrinth seal and the non-contact axial labyrinth seal are combined, so that the outwards-extending rotating shaft is sealed in a non-abrasion mode. The outwards-extending shaft end combined seal is compact in structure and lowers production and manufacturing cost, non-contact sealing is adopted, non-abrasion leakage resistance is achieved, and the using economical efficiency is greatly improved.
Description
Technical field
The utility model relates to the seal arrangement of bearing, specifically a kind of overhanging spindle nose combination seal.
Background technique
The machinery with overhanging running shaft, in general the bearing of back shaft is all to need to lubricate, and so just must consider the sealing problem of outrigger shaft, to avoid bearing portion lubricant oil leak and cause that equipment moves use problem from outrigger shaft.Most of machinery, in actual production is used, all exists because outrigger shaft oil leak causes that equipment operation is bad or shut down maintenance issue, thereby causes production run to be interrupted, and causes no small economic loss.For reducing outrigger shaft oil leak risk, most of machinery MANUFACTURER is the product by reliable, the long-lived Sealing MANUFACTURER of workmanship at overhanging shaft sealing place multiselect; And this type of Sealing mostly is contact seal, along with the increase of equipment operation period must regularly replace; And this type of Sealing MANUFACTURER mostly is offshore company, and purchase cost is quite high.
Model utility content
For the problem that in prior art, contact seal life cycle is short and cost is high, the utility model provides a kind of overhanging spindle nose combination seal.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of overhanging spindle nose combination seal, comprise first oil pooling hood, second oil pooling hood, radially disc and labyrinth ring, the fixing oil pooling hood that forms of first oil pooling hood and the docking of second oil pooling hood, and oil pooling hood ring set is in rotating shaft, radially one end of disc be arranged in oil pooling hood and ring set in rotating shaft, radially the outer peripheral surface of disc is provided with Sealing, and the seal and oil pooling hood form the sealing of non-contact radial labyrinth; Labyrinth ring ring set protrudes from one end of oil pooling hood at disc radially, and forms the axial labyrinth seal of non-contact with the axial annular groove on oil pooling hood exterior edge face;
First described oil pooling hood and second oil pooling hood are assembled together by locating stud, and fix and form oil pooling hood with screw bolt and nut;
Described labyrinth ring is fixed on radially on disc with marking closely screw;
In described oil pooling hood and the radially endoporus between disc, one end of close oil pooling hood exterior edge face is provided with felt ring seal;
The bottom of described second oil pooling hood is provided with the spill port being communicated with fuel tank.
The beneficial effects of the utility model:
The utility model adopts the sealing of non-contact radial labyrinth and axially labyrinth seal combination, and overhanging running shaft is obtained without wearing and tearing sealing; Oil pooling hood adds oil-return type design, guarantees that bearing portion lubricant oil returns to fuel tank smoothly; In oil pooling hood and the radially endoporus between disc, one end of close oil pooling hood exterior edge face is provided with felt ring seal, for preventing that oil leak from providing multi-ensuring, guarantees that outrigger shaft does not have the possibility of oil leak; The combination of aforementioned advantages makes the utility model compact structure on the whole, has reduced manufacturing cost; Be non-contact sealing simultaneously, accomplish, without wearing and tearing anti-leak, greatly to have improved its usage economy.

Embodiment
Below in conjunction with embodiment, the present invention is further elaborated.
A kind of overhanging spindle nose combination seal, comprise first oil pooling hood 1, second oil pooling hood 2, radially disc 3 and labyrinth ring 4, first oil pooling hood 1 and the fixing oil pooling hood that forms of second oil pooling hood 2 docking, and oil pooling hood ring set is in rotating shaft 11, radially one end of disc 3 be arranged in oil pooling hood and ring set in rotating shaft 11, radially the outer peripheral surface of disc 3 is provided with Sealing, and the seal and oil pooling hood form the sealing of non-contact radial labyrinth; Labyrinth ring 4 ring sets protrude from one end of oil pooling hood at disc 3 radially, and form the axial labyrinth seal of non-contact with the axial annular groove on oil pooling hood exterior edge face.
As shown in Figure 1 and Figure 2, a kind of overhanging spindle nose combination seal, comprise first oil pooling hood 1, second oil pooling hood 2, radially disc 3 and labyrinth ring 4, first oil pooling hood 1 and second oil pooling hood 2 are assembled together by locating stud 8, and with bolt 9 and the fixing oil pooling hood that forms of nut 10, the inner annular radial cavity that forms two intercommunications of oil pooling hood, and oil pooling hood ring set is in rotating shaft 11; Radially one end of disc 3 be arranged in oil pooling hood and ring set in rotating shaft 11, radially the outer peripheral surface of disc 3 is provided with Sealing, the seal forms non-contact radial labyrinth with oil pooling hood and seals; Labyrinth ring 4 ring sets protrude from one end of oil pooling hood at disc 3 radially, and form the axial labyrinth seal of non-contact with the axial annular groove on oil pooling hood exterior edge face; Labyrinth ring 4 use are marked closely screw 5 and are fixed on radially on disc 3; Non-contact axial seal guarantees that the lubricant oil leaking from radial seal along outrigger shaft can not leak into outside;
Two halves formula oil pooling hood has guaranteed the feasibility that radially disc 3 is installed; Second oil pooling hood 2 bottoms make a spill port being communicated with fuel tank 7, guarantee that the lubricant oil flowing in oil pooling hood from bearing returns to fuel tank smoothly, thereby reach the effect that prevents oil leak;
In described oil pooling hood and the radially endoporus between disc 3, one end of close oil pooling hood exterior edge face is provided with felt ring seal 6, and the lubricant oil that oil pooling hood place is leaked along outrigger shaft plays dual anti-leak effect;
The employing of measures first mentioned, makes the utility model compactness rational in infrastructure, has reduced manufacturing cost; Be non-contact sealing simultaneously, accomplish, without wearing and tearing anti-leak, to have solved the periodic replacement working service problem of contact seal, greatly improved its usage economy.
