Abstract
The utility model relates to a high-pressure oil seal of a half-coating rubber exposed framework, which comprises a framework, a rubber body and a spring, wherein the spring is sheathed on a seal lip of the rubber body; the rubber body is coated at the lower side of the framework in a half way; and an outer sealing end surface for forming the oil seal has a structure that the lower side is an excircle rubber sealing end surface coating the rubber body, and the upper side is an excircle framework sealing end surface from which the framework is exposed outside. The high-pressure oil seal of the half-coating rubber exposed framework has the advantages of being capable of maintaining the original shape of the oil seal, and being excellent in following performance and good in sealing effect, and is applicable to various oil seals applied to heavy-duty cars or various high-pressure occasions.
Description
Technical field
The utility model relates to a kind of Sealing, specifically, relates to a kind of half rubber-coated high pressure type oil sealing that exposes skeleton.
Background technique
In recent years, heavy-duty car market development at home presented the situation that grows steadily, and was more and more higher at the performance requirement of the sealing that operating conditions causes such as high speed, high temperature, overload, Environmental Conditions be abominable to automobile; The problem that exists as existing oil sealing still is to use the life-span short, phenomenons such as leak-down rate height.How to improve the sealability of oil sealing, reduce leak-down rate, improve life cycle, satisfy the demand of heavy-duty car industrial market fast development, domestic just each Sealing manufacturer is all at the product of the novel heavy duty automobile oil seal of developing and developing by fair means or foul.
Summary of the invention
The purpose of this utility model is at above-mentioned existing problems, provides a kind of and can keep that the original shape of oil sealing, trace performance are good, the half rubber-coated high pressure type oil sealing that exposes skeleton of good sealing effect.
The purpose of this utility model is to realize like this, comprise skeleton, rubber body and spring, spring housing is located on the sealing lip of rubber body, rubber body partly is coated on the downside of skeleton, is that downside is that the cylindrical rubber seal end face and the upside of rubber-coated body is the structure that exposes the cylindrical reinforced seal end face of skeleton and constitute oil sealing external sealed end face.
The utility model, the sealing labial surface of the sealing lip of rubber body is provided with return wire.
The utility model, the structure of return wire are waveform, wedge angle waveform, spirality or the one kind of oil-return groove that constitutes of splayed shape.
1), inheriting rubber material preferably on the advantage basis of wear resistance, acid-and base-resisting dielectric behavior, high-and low-temperature resistance better performances design principle of the present utility model is:, increase the material of high-abrasive material and its intensity of raising, become half rubber-coated body, it partly is coated on exposes on the skeleton; 2), oil sealing cylindrical seal face adopts that half is rubber-coated body, half is to expose skeleton seal face; 3), utilize aerodynamics and fluid dynamic pump to inhale principle, adopt the oil-return groove structure to keep sealing to imitate.
The utility model has following advantage: 1), the cylindrical seal face adopts half rubber-coated body, as long as under the situation that rubber body can bear or guarantee, its working life even surpass the main frame life-span; 2), the cylindrical seal face adopts half rubber-coated body and skeleton cylindrical interference sealing, the better seal performance is arranged, assembling easily, it has played the effect of double seal effect to the sealing of housing, can the occasion when high-pressure phenomena occurring more can show its superiority especially; 3), adopt half rubber-coated body structure, it had both had the intensity of support, and the followability of rubber body is arranged again, thereby made its trace performance than adopting the rubber body good airproof performance separately, had improved the intensity of sealability and cylindrical seal face; 4), half rubber-coatedly expose skeleton oil sealing, kept original oil seal structure form, it can with conventional oil front cover sample packing, keeping and assembling, do not need special protecting cover, reduced waste and environmental pollution.
Therefore, working life of the present utility model is considerably beyond previously used various oil sealing, and its also is adapted to produce in enormous quantities simultaneously, is to improve the heavy-duty car Sealing Performance of Oil Seal at present, prolong oil sealing a kind of better products in working life.
The utility model has and can keep the original shape of oil sealing, good, the advantage of good sealing effect of trace performance, is applicable to the various oil sealings of heavy-duty car or various high pressure applications.
Following embodiment is further described the utility model in conjunction with the accompanying drawings.
Description of drawings
Fig. 1 is an an embodiment's of the present utility model structural representation.
Among the figure, 1, skeleton; 2, rubber body; 3, spring; 4, sealing lip; 5, cylindrical rubber seal end face; 6, cylindrical reinforced seal end face; 7, sealing labial surface; 8, oil-return groove.
Embodiment
With reference to Fig. 1, present embodiment comprises skeleton 1, rubber body 2 and spring 3, spring 3 is sheathed on the sealing lip 4 of rubber body, rubber body 2 half is coated on the downside of skeleton 1, like this, the downside of oil sealing external sealed end face is the cylindrical rubber seal end face 5 of rubber-coated body, and the upside of oil sealing external sealed end face is the cylindrical reinforced seal end face 6 that exposes skeleton; The sealing labial surface 7 of the sealing lip 4 of this rubber body is provided with return wire; The structure of return wire can be to choose waveform, wedge angle waveform, spirality or the one kind of oil-return groove that constitutes 8 of splayed shape, certainly, is not limited to these shapes.
The utility model when return wire adopts spirality, generally adopts the single direction rotary setting, such as adopt left-handed or dextrorotation one of them and constitute oil-return groove.
Claims (3)
