Abstract
The utility model relates to an oil seal for a vehicle, in particular to an oil seal applicable to a narrower installation space. The oil seal applicable to the narrower installation space provided by the utility model comprises a base hole (1); a sealing lip (3) is arranged inside the base hole (1); the top end of the sealing lip (3) is clamped on a spring (2); the bottom end of the sealing lip (3) is clamped on an oil seal framework (4); and the sealing lip (3) and the oil seal framework (4) are respectively in interference fit with the base hole (1). According to the improved oil seal, the width size occupied by an outer circle part of the oil seal is reduced by using a steel wire ring to replace the former punching type steel board framework; and meanwhile, a lower outer circle sealing part is designed, so that a main lip opening has the sufficient size space, and the requirements of structural design and deformation space can be met.
Description
Technical field
The utility model relates to a kind of gasoline envelope, relates in particular to a kind of oil sealing that narrower space is used that is applicable to.
Background technique
In the situation that some is special, the installing space of oil sealing is very narrow, can't use the oil sealing of conventional structure.Because when oil sealing is installed, because the space is too narrow, oil sealing master lip will interfere in outer inner round side, cause main lip to deform, and can't normally bring into play seal action.Because oil sealing is too narrow, cause the skeleton width very little simultaneously, strength deficiency easily deforms.Even because oil sealing is too narrow, can't make at all.
The model utility content
Technique effect of the present utility model can overcome defects, and a kind of oil sealing that is applicable to narrow installing space is provided, and it takes up room little, good sealing effect.
For achieving the above object, the utility model adopts following technological scheme: it comprises a hole, and seat is provided with sealing lip in the hole, and the top of sealing lip is stuck on the spring, and the bottom of sealing lip is stuck on the oil tight skeleton, sealing lip, oil tight skeleton respectively with seat hole interference fit.
In order to satisfy sealing in such cases, must improve oil seal structure, the assurance oil sealing can reliably be installed, and satisfies seal request.
Oil tight skeleton comprises steel traveler and the rubber layer that is combined into one by vulcanization with steel traveler.Steel traveler adopts the spring steel materials such as 65Mn, SWRH72A, prevents that oil-seal outer from oval grade for deformation occuring.During assembling, steel traveler and seat hole interference fit guarantee that oil sealing assembles rear position and fixes.The rubber seal section of sealing lip same with a seat hole interference fit, play seal action, prevent that sealing medium from being revealed by the cylindrical position.
Oil sealing after the improvement, owing to adopting steel traveler to replace original punching type steel plate frame, reduced the width dimensions that oil-seal outer partly takies, designed simultaneously lower cylindrical sealed department, thereby guaranteed the main lip sufficient dimensional space that has part ownership, can satisfy its structural design and deformation spatial requirement.Oil sealing after the improvement and narrow assembly space have good adaptability, have not only guaranteed good installation but also have stable sealing.

Embodiment
The oil sealing that the utility model is applicable to narrow installing space comprises a hole 1, and seat is provided with sealing lip 3 in the hole 1, and the top of sealing lip 3 is stuck on the spring 2, and the bottom of sealing lip 3 is stuck on the oil tight skeleton 4, sealing lip 3, oil tight skeleton 4 respectively with seat hole 1 interference fit.Oil tight skeleton 4 comprises steel traveler and the rubber layer that is combined into one by vulcanization with steel traveler.
Claims (2)
1. oil sealing that is applicable to narrow installing space, comprise a hole (1), be provided with sealing lip (3) in the seat hole (1), it is characterized in that, the top of sealing lip (3) is stuck on the spring (2), the bottom of sealing lip (3) is stuck on the oil tight skeleton (4), sealing lip (3), oil tight skeleton (4) respectively with seat hole (1) interference fit.
2. the oil sealing that is applicable to narrow installing space according to claim 1 is characterized in that, oil tight skeleton (4) comprises steel traveler and the rubber layer that is combined into one by vulcanization with steel traveler.
