Abstract
The utility model relates to an internal structure of an integrally-assembled type double end surface magnetic force oil seal. The internal structure comprises a seal receptacle, two stationary rings,a movable ring, a permanent magnet and a seal ring. The internal structure is characterized in that two stationary rings are symmetrically mounted on the two sides in the seal receptacle, the movablering is mounted between the two stationary rings, and adopts the floating-type movable ring structure, the permanent magnet is placed between the floating-type movable ring and the seal receptacle, and an electrostatic prevention body is arranged between the permanent magnet and the floating-type movable ring. By adopting the structure and during the running of equipment, the two stationary ringssymmetrically mounted on the two sides can be absorbed to clamp the middle floating-type movable ring to perform automatic compensation through the magnetic force attraction of the permanent magnet,the two stationary rings on the two sides have the follow-up property and can compensate the play of a shaft along with a movable ring in a follow-up compensation manner, the floating-type movable ring can compensate the play of the shaft, and can adjust and center automatically, therefore, the internal structure provided by the utility model can effectively prevent the lubricant inside the equipment from leaking, and meanwhile, can make outside contaminant completely separate from the oil inside, thereby prolonging the service life of the sealing device, besides, the internal structure has the advantages of compact structure, convenient installation, etc.
Description
Technical field
The utility model belongs to the mechanical sealing technology field, particularly relates to a kind of unit loading type Double End Magnetic oil seal internal structure.
Background technique
At present, known Magnetic oil seal generally adopts the structure of single end face separate loading, and its compensating form is the compensation structure of rotating ring.Because rotating ring is fixing with axle in the Magnetic oil seal device, and stationary ring and equipment are fixed, therefore under the attraction of the magnetic force of permanent magnet, rotating ring and stationary ring also are difficult to compensate installation or equipment shakes the error of being brought, thereby cause whole oil sealing oil leak, and then influence the working life of equipment.
Summary of the invention
The utility model provides a kind of unit loading type Double End Magnetic oil seal internal structure of simple in structure, good seal performance for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of unit loading type Double End Magnetic oil seal internal structure, comprise sealing seat, stationary ring, rotating ring, permanent magnet and seal ring, it is characterized in that: the bilateral symmetry in the described sealing seat is installed stationary ring, between stationary ring and the sealing seat seal ring is installed, between two stationary rings rotating ring is installed, described rotating ring adopts floating type rotating ring structure, have and the seal ring that is coupling and touches in floating type rotating ring installed inside, be placed with permanent magnet between floating type rotating ring and the sealing seat, be provided with the antistatic body between permanent magnet and the floating type rotating ring.
The utility model can also adopt following technical measures:
Described sealing seat inboard is provided with snap ring.
Advantage and the good effect that the utlity model has are: because the utility model adopts Double End unit loading type structure, it is the bilateral symmetry installation stationary ring in the sealing seat, between stationary ring and the sealing seat seal ring is installed, the rotating ring of installing between two stationary rings adopts floating type rotating ring structure, promptly have and the seal ring that is coupling and touches in floating type rotating ring installed inside, be placed with permanent magnet between floating type rotating ring and the sealing seat, be provided with the antistatic body between permanent magnet and the floating type rotating ring.Therefore adopt said structure when equipment running process, can compensate automatically by the magnetic force of permanent magnet, but the trace of floating type rotating ring compensating shaft is beated, and can regulate automatically and self-alignment, and be easy to be installed in the place that easy generation is leaked, so the utility model can effectively stop the device interior oil leak, environmental contaminants and inner fluid are isolated fully, and can be installed in former skeleton oil sealing place, thereby the raising seal life, model utility also has compact structure, advantage such as easy for installation in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, sealing seat; 2, stationary ring; 3, rotating ring; 4, permanent magnet; 5, seal ring; 6, snap ring; 7, axle; 8, seal ring; 9, antistatic body.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment:
See also Fig. 1, a kind of unit loading type Double End Magnetic oil seal internal structure, comprise sealing seat 1, stationary ring 2, rotating ring 3, permanent magnet 4 and seal ring (5,8), the bilateral symmetry of described sealing seat 1 inside is installed stationary ring 2, seal ring 5 is installed between stationary ring 2 and the sealing seat 1, its seal ring 5 is by the sealing seat 1 inboard snap ring that is provided with 6 chuckings, rotating ring 3 is installed between two stationary rings 2, described rotating ring 3 adopts floating type rotating ring structure, have and axle 7 seal rings that contact 8 in floating type rotating ring 3 installed inside, be placed with permanent magnet 4 between floating type rotating ring 3 and the sealing seat 1, be provided with antistatic body 9 between permanent magnet 4 and the floating type rotating ring 3.
Therefore adopt said structure when equipment running process, can compensate automatically by the magnetic force of permanent magnet, but the trace of floating type rotating ring compensating shaft is beated, and can regulate automatically and self-alignment, and be easy to be installed in the place that easy generation is leaked, so the utility model can effectively stop the device interior oil leak, environmental contaminants and inner fluid are isolated fully, and can be installed in former skeleton oil sealing place, thereby the raising seal life, model utility also has compact structure, advantage such as easy for installation in addition.
