Abstract
The utility model discloses a double-surface oil seal, comprising a first oil seal and a second oil seal. The double-surface oil seal is characterized in that the periphery of the first oil seal is provided with a sleeve part extending towards one side along the axial direction; the second oil seal is embedded in the sleeve part; the first oil seal is provided with a sealing lip; the second oil seal is provided with two symmetrical sealing lips; and the inner diameters of the three sealing lips are consistent and ring-shaped spring grooves at the outer sides of the three sealing lips are internally and respectively provided with a hooping spring in a sheathing manner. After optimization, due to the arrangement of the three sealing lips, the sealing effect can be better ensured, and the two sealing lips in the second oil seal are symmetrically arranged, so that the manufacture and forming can be convenient. The double-surface oil seal disclosed by the utility model has the characteristics of higher stability and reliability and better sealing effect, can effectively ensure that sealing is realized for different substances of the two end surfaces, and prevent a machine body from being damaged due to oil leakage or entering of foreign substances.
Description
Technical field
The utility model relates to a kind of oil sealing, and is especially a kind of for sealed at both ends double-sided oil seal.
Background technique
Dynamic power machine is when transferring power, all need to seal with rubber parts such as oil sealings, the outer ring of oil sealing and body carry out the interference assembling, resiliently deformable by rubber between body and the oil sealing seals, inner ring then is tightly to surround transmission shaft by the resiliently deformable of rubber, makes its inside and outside material relatively isolated; Avoid the materials such as body leakage of oil or outside water, air, silt to enter internal body with this, thereby damage body.
Common oil sealing generally can only be used for end sealing, is difficult to realize sealed at both ends.
CN101539202B once disclosed a kind of combined double-sided oil seal, belonged to a kind of combined double-sided oil seal that medium in the adjacent different chamber of lubrication system is sealed simultaneously.Its its structure comprises inner oil seal and outer oil seal, wherein inner oil seal and outer oil seal comprise respectively sealing lip, skeleton and spring, and return wire is set all on the sealing lip, wherein, the bottom surface of inner oil seal and outer oil seal is relative, the sealing lip of inner oil seal and outer oil seal is opposite direction, and the return wire opposite direction on two sealing lips, interconnects between inner oil seal and the outer oil seal.This oil sealing is easy for installation, and the space that takies after the installation reduces greatly, is convenient to simultaneously oil sealing is checked, can change the oil sealing that damages timely and accurately, has guaranteed normally carrying out of lubricated work.
But this existing combined double-sided oil seal, docking links to each other between inner oil seal and the outer oil seal, and it is relatively poor that it connects reliability, causes easily during installation to come off, and also has simultaneously the relatively poor defective of sealing effect.
The model utility content
For above-mentioned deficiency, technical problem to be solved in the utility model is how to provide a kind of stability and reliability higher, the better double-sided oil seal of sealing effect.
In order to solve the problems of the technologies described above, adopted following technological scheme in the utility model.
A kind of double-sided oil seal comprises the first oil sealing and the second oil sealing, it is characterized in that, the first oil sealing periphery has the sleeve part that extends vertically to a side, and described the second oil sealing is embedded in described sleeve part.
In this programme, adopt in the first oil sealing periphery a sleeve part to be set, then the second oil sealing interference fit is embedded in sleeve, like this, both are difficult for causing coming off in conjunction with very reliable, have guaranteed the reliability and stability of installing.
As optimization, described the first oil sealing has a sealing lip, and described the second oil sealing has two symmetrically arranged sealing lips, and three sealing lip internal diameters unanimously and in the circular spring groove in three sealing lip outsides respectively are arranged with a banding spring.After optimizing like this, have three sealing lips, can guarantee better sealing effect, two sealing lips in the second oil sealing are symmetrical arranged, can be so that manufacture shape.
In sum, double-sided oil seal of the present utility model, it is higher to have stability and reliability, and the better characteristics of sealing effect can guarantee the different material of both ends of the surface is realized sealing effectively, avoid body to damage because leakage of oil or external substance enter.

Fig. 2 is the structural representation of independent the first oil sealing in the utility model.
Fig. 3 is the structural representation of independent the second oil sealing in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
During implementation, as shown in Figure 1-Figure 3, a kind of double-sided oil seal comprises that the first oil sealing 1 and the second oil sealing 2, the first oil sealings 1 periphery have the sleeve part 3 that extends vertically to a side, and described the second oil sealing 2 is embedded in described sleeve part 3.Described the first oil sealing 1 has a sealing lip 4, and described the second oil sealing 2 has in the circular spring groove in consistent and three the sealing lip outsides of 5, three sealing lip internal diameters of two symmetrically arranged sealing lips and respectively is arranged with a banding spring 6.
Claims (2)
1. a double-sided oil seal comprises the first oil sealing and the second oil sealing, it is characterized in that, the first oil sealing periphery has the sleeve part that extends vertically to a side, and described the second oil sealing is embedded in described sleeve part.
2. double-sided oil seal as claimed in claim 1, it is characterized in that, described the first oil sealing has a sealing lip, and described the second oil sealing has two symmetrically arranged sealing lips, and three sealing lip internal diameters unanimously and in the circular spring groove in three sealing lip outsides respectively are arranged with a banding spring.
