Abstract
The utility model belongs to the technical field of sealing elements, and in particular relates to a double main lip combined oil seal. The combined oil seal comprises an outer oil seal and an inner oil seal which are mutually combined; the outer oil seal is a spring-free oil seal consisting of an outer framework and an outer sealing body; the inner oil seal is a spring oil seal consisting of an inner framework, a spring and an inner sealing body; a main sealing lip is arranged on the outer sealing body of the outer oil seal, and a main sealing lip is also arranged on the inner sealing body of the inner oil seal; and a secondary sealing lip is also arranged on the inner sealing body of the inner oil seal. By improving the conventional combined oil seal, the defects of poor comprehensive sealing performance and poor large eccentricity resistance of the conventional combined oil seal are overcome; and the double main lip combined oil seal has the advantages of good sealing performance and high large eccentricity resistance, and is applied to occasions with high-rotation large eccentricity, low-rotation large eccentricity and the like.
Description
Technical field
The utility model belongs to the Sealing technical field, specifically, relates to a kind of two main lip combined type oil sealing.
Background technique
Present combined type oil sealing; Mostly be by the conventional structure of outer oil seal with the mutually common combination of inner oil seal;, its inner oil seal can influence the sealability of whole oil sealing if losing efficacy; And the anti-eccentric performance of its outer oil seal is not ideal enough, so influenced the Applicable scope of its combination oil seal, has oil sealing comprehensive sealing poor-performing and the relatively poor shortcoming of anti-large eccentricity ability.
The model utility content
The utility model provides a kind of two main lip combined type oil sealing, and it makes it overcome oil sealing comprehensive sealing poor-performing and the relatively poor shortcoming of anti-large eccentricity ability through original combined type oil sealing is improved.The technological scheme that the utility model adopted is:
Two main lip combined type oil sealings comprise the outer oil seal and the inner oil seal of mutual combination; Said outer oil seal adopts the no spring oil sealing of being made up of outer skeleton and external sealed body, and said inner oil seal employing has a spring oil sealing by what inner frame, spring and interior seal were formed; The external sealed body of said outer oil seal is provided with a primary seal lip, also is provided with a primary seal lip on the interior seal of said inner oil seal.
In the technological scheme of the utility model, also have following additional technical feature:
Also be provided with a secondary sealing lip on the interior seal of said inner oil seal.
Compared with prior art; The advantage and the good effect of the utility model are: the two main lip combined type oil sealing of the utility model; It is through improving original combined type oil sealing; Make it overcome oil sealing comprehensive sealing poor-performing and the relatively poor shortcoming of anti-large eccentricity ability, have good seal performance and the strong advantage of anti-large eccentricity ability, be applicable to special occasions such as high rotating speed large eccentricity and slow-speed of revolution large eccentricity.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described further:
Fig. 1 is two main its structural representation of lip combined type oil sealing of the utility model.
Among the figure, 1 is outer skeleton, and 2 is the external sealed body, and 3 is inner frame, and 4 is interior seal, and 5 is spring, and 6 is primary seal lip, and 7 is secondary sealing lip.
Embodiment
Embodiment
As shown in Figure 1, two main lip combined type oil sealings comprise the outer oil seal and the inner oil seal of mutual combination; Said outer oil seal adopts the no spring oil sealing of being made up of outer skeleton 1 and external sealed body 2, and said inner oil seal employing has a spring oil sealing by what inner frame 3, spring 5 and interior seal 4 were formed; The external sealed body 2 of said outer oil seal is provided with a primary seal lip 6, also is provided with a primary seal lip 6 on the interior seal 4 of said inner oil seal; Also be provided with a secondary sealing lip 7 on the interior seal 4 of said inner oil seal.
Like this in when work, the two main lip combined type oil sealing of the utility model, it adopts fabricated structure, and inner oil seal is the common spring oil sealing that has, and outer oil seal is no spring oil sealing; It in use even the inner oil seal seal failure can not influence the sealability of whole oil sealing yet, thereby improves the sealability of whole oil sealing; Again because its outer oil seal is no spring oil sealing, can be anti-, so this structure oil sealing Applicable scope is wider than large eccentricity, and the adjustment through internal oil seal structure, can be applicable to special occasions such as high rotating speed large eccentricity and slow-speed of revolution large eccentricity.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the mode of execution of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here can't give exhaustive to all mode of executions.Conspicuous variation that every technological scheme that belongs to the utility model is amplified out or change still are in the row of the protection domain of the utility model.
