Abstract
The utility model relates to a sealing device, in particular to an oil seal. The utility model provides an oil seal, and the seal lip and the external diameter of the oil seal are adopted different rubber materials. The utility model comprises a frame and a sealed body, on which a seal lip is equipped. The sealed body comprises an internal sealed body and an external sealed body that are mutually separated. The seal lip is positioned on the internal sealed body; the internal sealed body is equipped as a rubber, and the external sealed body is equipped as another rubber. Adopting the oil seal of the utility model, the sealing property of the oil seal is strengthened, the oil seal cost is decreased, and the rubber material is saved. The oil seal of the structural style of the utility model can be widely used in the field of oil seal manufacture.
Description
Technical field
The utility model relates to a kind of seal arrangement, specifically, relates to a kind of oil sealing.
Background technique
As shown in Figure 1, oil sealing of the prior art, generally all comprise skeleton 2 and seal, the oil sealing whether skeleton 2 is also arranged, seal comprises and generally comprises sealing lip 4 and 5 and the external sealed body, the sealing lip of oil sealing of the prior art and outer seal lip generally all are set to a kind of rubber material, and in application often the requirement to the rubber material of sealing lip and external sealed body be different, if interior seal and external sealed body adopt identical materials to cause to a certain degree waste to material, also can increase the cost of oil sealing simultaneously.
Summary of the invention
The utility model provides a kind of sealing lip and oil sealing external diameter to adopt the oil sealing of different rubber materials.
The technical solution of the utility model is such: it comprises skeleton and seal, sealing lip is set on the seal, seal comprises interior seal and the external sealed body that is separated from each other, its sealing lip is positioned on the seal, interior seal is set to a kind of rubber, the external sealed body is set to another kind of rubber, and sealing lip is provided with main lip and secondary lip, and the fixing spring circle is set on the main lip.
Adopt oil sealing of the present utility model, not only make the sealing of having strengthened oil sealing, and reduced the cost of oil sealing, saved rubber material.
Description of drawings
Fig. 1 is prior art constructions figure of the present utility model;
Fig. 2 is a structural drawing of the present utility model.
Embodiment
As shown in Figure 2, oil sealing of the present utility model comprises skeleton 2 and seal, sealing lip is set on the seal, seal comprises interior seal 6 and the external sealed body 1 that is separated from each other, its sealing lip is positioned on the seal 6, and interior seal 6 is set to a kind of rubber, and external sealed body 1 is set to another kind of rubber, sealing lip is provided with main lip 4 and secondary lip 5, on the main lip 4 fixing spring circle 3 is set.
Of the present utility model pair of rubber oil sea is by skeleton 2, spring ring 3 on interior seal 6 and external sealed body 1 and the main lip is formed, interior seal 6 and external sealed body 1 are by skeleton 2 becoming one structures, seal 6 just can be arranged to different rubber materials as required with external sealed body 1 like this, it is reasonable that interior seal 6 can be arranged to performance, more wear-resisting rubber material, external sealed body 1 can be arranged to performance as required and hang down the rubber material of some, so not only satisfied the different performance requirement of interior seal 6 and external sealed body 1, oil sealing performance and working life have been improved, saved material so to a certain extent, reduce the cost of oil sealing, thereby reduced the cost of using the machine of oil sealing.The sealing lip setting of oil sealing has been provided with the spring ring 3 of fixation by main lip 4 and secondary lip 5 on the main lip 4, thereby makes the better tightness of oil sealing.The interior seal 6 of oil sealing owing to adopt different rubber materials, so adopt the rubber material of same color also can adopt the rubber material of different colours, makes oil sealing more attractive in appearance with external sealed body 1.
The material of seal 6 and external sealed body 1 also can need to be provided with in of the present utility model, often wear-resisting material is arranged in the place that friction takes place, be arranged to resistant to elevated temperatures material in the high place of temperature, the oil sealing of the utility model structural type can be widely used in the manufacturing field of oil sealing.
