Description
Technical field:
The utility model relates to the many oil sealing envelopes of a kind of one, belongs to seal oil part technical field.
Background technique:
Oil sealing is used to the mechanical component of oil sealing (oil is modal liquid substance in transmission system, also makes a general reference the meaning of general liquid substance), and the parts needing in transmission part to lubricate are isolated with parts of exerting oneself by it, are unlikely to allow oil seepage.Static seal and motive sealing (general to-and-fro motion) with Sealing Sealing.The representative form of oil sealing is TC oil sealing, and this is the two-lip seal of the completely coated band self-tightening spring of a kind of rubber, and oil sealing in general often refers to this tc outside framework oil seal.The common used material of oil sealing has: nitrile butadiene rubber, fluorine rubber, silicone rubber, acrylate rubber, polyurethane, teflon etc.When selecting the material of oil sealing, the compatibility of material to working medium must be considered, to the adaptability of operating temperature range and antelabium to follow-up capability during running shaft High Rotation Speed.
Oil sealing is in the market all the alone oil sealing of one, when oil is through seal, is easy to leakage; especially, after seal time length, after there is wear phenomenon, often there will be oil leakage phenomenon in various degree; sealing effect extreme difference, makes seal failure, can not meet the sealing demand of lubricant oil.
Model utility content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide the many oil sealing envelopes of a kind of one.
The many oil sealing envelopes of a kind of one of the present utility model, it comprises the first seal, the second seal, the first spring, the second spring, the outer peripheral surface of the first seal is provided with the second seal, the inner side of the first seal and the second seal is respectively arranged with the first spring and the second spring.
The beneficial effects of the utility model: its reasonable in design, beautiful shape, modern design is unique, simple to operate, easy to use, adopt multiple seal and multiple spring to form, owing to having multi-sealed body and spring, the phenomenon that can reduce leakage of oil occurs, and has good sealing effect, meets the demand of actual conditions.
Accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model;
Fig. 3 is the structural representation of embodiment two;
Fig. 4 is the structural representation of embodiment three.
1-first seal; 2-second seal; 3-first spring; 4-second spring; 5-the 3rd seal; 6-the 3rd spring; 7-the 4th seal; 8-the 4th spring.
Embodiment:
Embodiment one: as Fig. 1, shown in Fig. 2, this embodiment is by the following technical solutions: it comprises the first seal 1, second seal 2, first spring 3, second spring 4, the inner side outer peripheral surface of the first seal 1 being provided with the second seal 2, first seal 1 and the second seal 2 is respectively arranged with the first spring 3 and the second spring 4.
Embodiment two: as shown in Figure 3, this embodiment is with the difference of embodiment one: the outer peripheral surface of the second described seal 2 is provided with the 3rd seal 5, and the inner side of the 3rd seal 5 is provided with the 3rd spring 6, other constituent elements are identical with embodiment one with annexation.
Embodiment three: as shown in Figure 4, this embodiment is with the difference of embodiment two: the outer peripheral surface of the 3rd described seal 5 is provided with the 4th seal 7, and the inner side of the 4th seal 7 is provided with the 4th spring 8, other constituent elements are identical with embodiment two with annexation.
This embodiment in use, when oil is through the first seal 1 seepage, then can flow to above the second seal 2, then the 3rd seal 5, the 4th seal 7 is flowed to successively, like this then the generation of oil leakage phenomenon can be reduced, according to the increase in demand of user or the quantity reducing Sealing and spring, to reach better sealing effect, can effectively prevent leaking of lubricant oil.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
