Abstract
The utility model relates to a rotary shaft lip seal for a steel supporting ring structure. The rotary shaft lip seal comprises a rubber lip, an oil seal skeleton arranged inside the rubber lip and a compression spring arranged in a groove at the lip end of the rubber lip, wherein the oil seal skeleton is connected with the rubber lip through vulcanization, and the rotary shaft lip seal also comprises a steel supporting ring compressed with the rubber lip. The rotary shaft lip seal for the steel supporting ring structure improves the abrasion of the lip for the rotary shaft lip seal in the prior art to further improve the service life of the rotary shaft lip seal as well as the feasibility of industrial production.
Description
Technical field
The utility model relates to a kind of High-pressure oil sealing, particularly a kind of rotary shaft lip seal that press-fits shaped steel body support ring structure.
Background technique
In the prior art, common rotary shaft lip seal structure is made up of rubber lip, the oil tight skeleton that is arranged on described rubber lip inside, plastic support ring and the deflation spring that is arranged in the lip end recesses of described rubber lip; Oil tight skeleton, rubber lip and plastic support ring three are grouped together by high temperature vulcanized, because the existence of plastic support ring is arranged, the rubber lip wearing and tearing are very fast, cause the life-span of rotary shaft lip seal short, be unfavorable for the long-term use of vehicle and equipment, simultaneously, because the plastic support ring can't accurately be located, the industrialized production ability is relatively poor in process of production for the rotary shaft lip seal of plastic support ring structure.
Summary of the invention
Technical problem to be solved in the utility model is: improve rotary shaft lip seal lip wearing and tearing in the prior art, and then the life-span of improving rotary shaft lip seal, improve industrial feasibility simultaneously.
The utility model is achieved by the following technical solution: a kind of rotary shaft lip seal that press-fits shaped steel body support ring structure, comprise rubber lip, be arranged on the oil tight skeleton of described rubber lip inside and be arranged on deflation spring in the lip end recesses of described rubber lip, described oil tight skeleton is connected by sulfuration with described rubber lip, also comprises the steel body support ring that is fitted in described rubber lip.Employing press-fits shaped steel body support ring structure, steel body support ring need not to vulcanize simultaneously with oil tight skeleton and rubber lip, steel body support ring is the back press mounting structure, and oil tight skeleton is identical with the General Purpose Rubber oil sealing with the high temperature vulcanized process of rubber lip, follow-uply press-fits steel body support ring; Make the simple in structure of rotary shaft lip seal, realizability is strong.
The rotary shaft lip seal that press-fits shaped steel body support ring structure of the present utility model has following beneficial technical effects: can improve the wearing and tearing of rotary shaft lip seal lip under the situation that does not reduce high pressure resistant pressure, and then the life-span of improving rotary shaft lip seal, can greatly improve industrial feasibility simultaneously.
Description of drawings
Fig. 1 is the cross-sectional view that press-fits the rotary shaft lip seal of shaped steel body support ring structure of the present utility model.
Wherein: the 1-oil tight skeleton, the 2-rubber lip, 3-tightens spring, 4-steel body support ring.
Mode of execution
As shown in Figure 1, the rotary shaft lip seal that press-fits shaped steel body support ring structure of present embodiment is the High-pressure oil sealing that a kind of oil pump for engine uses, comprise rubber lip 2, be arranged on the oil tight skeleton 1 of described rubber lip 2 inside and be arranged on deflation spring 3 in the lip end recesses of described rubber lip 2, described oil tight skeleton 1 is connected by sulfuration with described rubber lip 2, also comprises the steel body support ring 4 that is fitted in described rubber lip 2.Described steel body support ring 4 need not to vulcanize simultaneously with described oil tight skeleton 1 and described rubber lip 2, described steel body support ring 4 is the back press mounting structure, described oil tight skeleton 1 is identical with the General Purpose Rubber oil sealing with described rubber lip 2 high temperature vulcanized processes, follow-uply press-fits described steel body support ring 4.The rotary shaft lip seal that press-fits shaped steel body support ring structure of present embodiment simple in structure, realizability is strong; Have high pressure resistant, wear-resistant, easy characteristics of producing.
