Abstract
The utility model belongs to the field of sealing pieces, particularly relates to an eccentricity-proof oil seal, which comprises a seal body, a framework and a spring. A seal lip of the seal body is arranged to be in a structure in the shape of a Chinese character 'T', and the seal body, the framework and the spring are vulcanized into an integral structure. The eccentricity-proof oil seal can solve the problem of lip overturning and spring falling which exist in the prior oil seal, overcomes the shortcoming of poor stability and poor sealing performance, and has the advantages of being reasonable in structure, good in eccentricity-proof effect, good in working stability and good in sealing performance.
Description
Technical field
The utility model belongs to the Sealing field, specifically, relates to a kind of anti-eccentric oil sealing.
Background technique
Present oil sealing; The common composite structures that adopt seal, skeleton and spring more, it is applicable to the situation that axle is installed from forward more, because of it is common FB structure; Ability large eccentricity not; So, then exist easily and turn over lip and fall the problem of spring, thereby have the shortcoming of poor stability and sealing difference when axle during from reverse installations.
The model utility content
The utility model provides a kind of anti-eccentric oil sealing, and it can solve existing lip and the problem of falling spring of turning over of present oil sealing, overcomes the shortcoming of poor stability and sealing difference.
The technological scheme that the utility model adopted is:
Anti-eccentric oil sealing comprises seal, skeleton and spring, and the sealing lip of said seal is made as " several " font structure.
In the technological scheme of the utility model, also have following additional technical feature:
Said seal, skeleton and spring are the structure of one for sulfuration.
Compared with prior art; The advantage and the good effect of the utility model are: the anti-eccentric oil sealing of the utility model; It can solve existing lip and the problem of falling spring of turning over of present oil sealing; Overcome the shortcoming of poor stability and sealing difference, it has, and rational in infrastructure, anti-eccentric effect is good, working stability good and the advantage of good seal performance.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described further:
Fig. 1 is original oil seal structure schematic representation;
Fig. 2 is the anti-eccentric oil seal structure schematic representation of the utility model.
Among the figure, 1 is seal, and 2 is skeleton, and 3 is spring, and 4 is sealing lip.
Embodiment
Embodiment
Be illustrated in figure 1 as original oil sealing; It is the common composite structure of seal 1, skeleton 2 and spring 3, and it is applicable to the situation that axle is installed from forward more, because of it is common FB structure; Ability large eccentricity not; So, then exist easily and turn over lip and fall the problem of spring, thereby have the shortcoming of poor stability and sealing difference when axle during from reverse installations.Shown in Figure 2 is the anti-eccentric oil sealing of the utility model, comprises seal 1, skeleton 2 and spring 3, and the sealing lip 4 of said seal 1 is made as " several " font structure; Said seal 1, skeleton 2 and spring 3 are the structure of one for sulfuration.
When work, the anti-eccentric oil sealing of the utility model, its seal 1, skeleton 2 and spring 3 make it in the vibration or the bigger occasion of beating for sulfuration is the structure of one like this, and spring is difficult drop-off also; The sealing lip 4 of its seal 1 is made as " several " font structure, can adapt to eccentric big occasion, improves its anti-eccentric effect, is applicable to the situation of axle from reverse installation.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the mode of execution of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here can't give exhaustive to all mode of executions.Conspicuous variation that every technological scheme that belongs to the utility model is amplified out or change still are in the row of the protection domain of the utility model.
Claims (2)
1. anti-eccentric oil sealing comprises seal (1), skeleton (2) and spring (3), and it is characterized in that: the sealing lip (4) of said seal (1) is made as " several " font structure.
