Abstract
The utility model provides a double-layer combined framework oil seal which is characterized in that the double-layer combined framework oil seal is formed by pressing an inner framework oil seal into an outer framework oil seal and bonding the inner framework oil seal with the outer framework oil seal; the main lip opening of the inner framework oil seal and the main lip opening of the outer framework oil seal are coaxially arranged; and spiral return lines are arranged on an inner sealing lip and an outer sealing lip respectively. By arranging the double layers of framework oil seals, the effects of the oil seal are more reliable. In addition, as the inner oil seal framework is pressed into the outer oil seal framework, the assembling and the disassembling of the double-layer combined framework oil seal are very convenient. The double-layer combined framework oil seal can achieve effects only by combining the framework oil seals of different types and specifications in the prior art, the cost is saved, and the practicability is very strong.
Description
Technical field
The utility model belongs to automotive trannsmission system input, output terminal sealed member, specifically is meant a kind of double-layer combined outside framework oil seal.
Background technique
The individual layer oil seal structure that adds dust excluder lips at present at the normally main cutting edge of oil sealing that automotive trannsmission system is imported, output terminal adopted.But this structural type is simple, and sealing is not very reliable, and working life is on the low side.In order to address this problem, application number is to propose a kind of dual-oil seal structure in 200720099396 the patent, but the dual-oil seal structure is unfavorable for assembling and dismounting, and cost has also increased more.
Summary of the invention
The purpose of this utility model is to provide a kind of sealing effect reliable according to above-mentioned deficiency, is convenient to assembling and dismounting simultaneously, and lower-cost double-layer combined outside framework oil seal.
The utility model adopts following technological scheme: a kind of double-layer combined outside framework oil seal is characterized in that: it is to be pressed into an outer skeleton oil sealing and bonding forming by an inner frame oil sealing; The main lip coaxial arrangement of described inside and outside two outside framework oil seals; Be equipped with the spiral return wire on sealing lip and the outer seal lip in described.
Described inner frame oil sealing is relative with the opening of outer skeleton oil sealing.
Described inner oil seal master lip is provided with the teflon paster.
The utility model is by being provided with two-layer outside framework oil seal, thereby makes the effect of oil sealing more reliable.Simultaneously, because the inner oil seal skeleton is to be pressed in the outer oil seal skeleton, therefore assembling and dismounting are all very convenient.The utility model only need make up the outside framework oil seal of different model specification in the prior art and can be effective, and saves cost, has very strong practicability.
Description of drawings
Fig. 1 is a sectional view of the present utility model;
Among the figure: 1. the outer oil seal skeleton, 2. the inner oil seal skeleton, 3. inner spring, 4. outer spring, 5. dust excluder lips, 6. outer oil seal master lip, 7. inner oil seal master lip, 8. in sealing lip, 9. outer seal lip, 10. teflon paster, 11. spiral return wires.
Embodiment
As shown in Figure 1, double-layer combined outside framework oil seal of the present utility model is to be pressed into an outer skeleton oil sealing and bonding forming by an inner frame oil sealing, and the inner frame oil sealing is relative with the opening of outer skeleton oil sealing.Described inner frame oil sealing comprises inner oil seal skeleton 2, interior sealing lip 8 and inner spring 3, and described outer skeleton oil sealing comprises outer oil seal skeleton 1, outer seal lip 9 and outer spring 4.Outer oil seal skeleton 1 supports outer seal lip 9, sealing lip 8 in inner oil seal skeleton 2 supports, and interior sealing lip 8 bonds together with outer oil seal skeleton 1.Also be provided with dust excluder lips 5 and outer oil seal master lip 6 with the end of touching that is coupling on the described outer seal lip 9; Also be provided with inner oil seal master lip 7 with the end of touching that is coupling on the sealing lip 8 in described, described inner oil seal master lip 7 places are provided with teflon paster 10.Described outer oil seal master lip 6 and inner oil seal master lip 7 coaxial arrangement.Be equipped with spiral return wire 11 on sealing lip 8 and the outer seal lip 9 in described.
The inner frame oil sealing that outer skeleton oil sealing that outer seal lip 9, outer oil seal skeleton 1 and outer spring 4 are formed and interior sealing lip 8, inner oil seal skeleton 2 and inner spring 3 are formed links together by the interference fit that two springs produce, and plays the effect of oil sealing.And outer skeleton oil sealing and inner frame oil sealing carry out oil sealing to axle simultaneously, make sealing more reliable.Simultaneously, the utility model only can be effective by the combination of existing outside framework oil seal, and is simple and reliable for structure.
