Description
Technical field
The utility model relates to a kind of combined outside framework oil seal devices, belong to sealing element technical field.
Background technique
Oil sealing be for oil sealing (oil is the most common liquid substance in transmission system, also refer to general liquid substance it
Meaning) mechanical organ, the component for needing to lubricate in transmission parts is isolated with component of contributing for it, is unlikely to allow oil seepage.
Common oil sealing is typically only capable to that a kind of medium is isolated, and the situation for needing to be isolated two kinds of liquid mediums is then not suitable for.
Utility model content
Purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of combined reinforced seal dress
It sets.
Technical solution: in order to solve the above technical problems, the technical solution adopted by the utility model is:
A kind of combined outside framework oil seal device, including external shell and oil sealing ontology；The oil sealing ontology includes that rubber is close
Seal ring, the outer ring of the rubber seal ring are static seal surface, and the inner ring of rubber seal ring is dynamic sealing surface, and connection rubber is close
The part of seal ring outer ring and inner ring is transition part；The dynamic sealing surface includes the first primary seal lip and the second primary seal lip, the
One primary seal lip and the second primary seal lip outer portion are respectively equipped with annular groove, are equipped with spring in annular groove；The rubber is close
Seal ring embeds section class N-shaped metallic framework, and class N-shaped skeleton is axially extending along static seal surface, until end transition portion, in mistake
The portion of crossing is bent into S type, is finally inserted dynamic sealing surface；The external shell is section L-type metallic framework.
Further, described section L-type metallic framework axial direction one end with rubber seal ring is tangent is bonded, radial one end is complete
It is exposed.
Further, the static seal surface is equipped with chamfering with junction on the outside of transition part.
Further, first primary seal lip is equal with the second primary seal lip annular diameters.
Further, the rubber seal ring is made of hydrogenation nitrile rubber.
Further, the L-type metallic framework, class N-shaped metallic framework and spring are all made of carbon steel material and are made.
The utility model has the advantages that combined outside framework oil seal device provided by the utility model, has double main lip designs, can isolate two
Kind sealing liquid；L-type metallic framework, to reinforce the rigidity of oil sealing, and stop portions pressure；Class N-shaped metallic framework increases rigid
Property deform oil sealing will not easily；Spring provides the certain binding force of oil sealing lip and extends the oil sealing service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1, a kind of combined outside framework oil seal device, including external shell and oil sealing ontology.The oil sealing ontology
Including rubber seal ring, the outer ring of the rubber seal ring is static seal surface 1, and the inner ring of rubber seal ring is dynamic sealing surface
2, the part of connecting rubber sealing ring outer ring and inner ring is transition part 3；The static seal surface 1 and 3 outside junction of transition part
Equipped with chamfering 7, convenient for the assembly of oil sealing.
The dynamic sealing surface 2 includes the first primary seal lip 21 and the second primary seal lip 22, first primary seal lip 21
It is equal with 22 annular diameters of the second primary seal lip；First primary seal lip 21 and 22 outer portion of the second primary seal lip are respectively equipped with annular
Groove, annular groove is interior to be equipped with spring 4；The spring 4 is made of carbon steel material, is provided the certain binding force of oil sealing lip and is prolonged
The long oil sealing service life.
The external shell is section L-type metallic framework 6, section L-type metallic framework axial direction one end 61 and rubber seal ring
Tangent, radial one end 62 is completely exposed.L-type metallic framework 6 is made of carbon steel, to reinforce the rigidity and stop portions of oil sealing
Pressure.
Section class N-shaped metallic framework 5 is embedded with inside the rubber seal ring, class N-shaped metallic framework 5 is along static seal surface axis
To extension, until end transition portion, is bent into S type in transition part, is finally inserted dynamic sealing surface；Class N-shaped metallic framework 5 is adopted
It is made of carbon steel material, increasing rigidity deform oil sealing will not easily.
The rubber seal ring is made of hydrogenation nitrile rubber, has good chemical stability and elastic nature, right
Axis has good sealing effect.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
