Abstract
The utility model discloses a seal ring for a shaft. The seal ring for the shaft comprises a seal ring body and a block ring. Seal lips are arranged on the inner side of the seal ring body in an up-and-down mode. The block ring is inlaid between the seal lips and fixedly connected with the seal ring body. Specifically, the seal ring for the shaft is sleeved on a piston rod, when the piston works, two ends of the seal ring for the shaft are under the action of pressure, the seal ring body stresses and extrudes inwards, the seal lips are enabled to be attached to the piston rod, and the seal ring for the shaft is enabled to achieve a sealing effect. The block ring plays a role of supporting the seal ring body, avoids that the seal ring body deforms, and meanwhile plays a role of auxiliary seal.
Description
Technical field
The utility model relates to a kind of axle seal ring for the sealing of piston rod two-way series.
Background technique
Piston rod is a kind of connected element of supporting piston acting, and major applications is frequent, a high moving element of technical requirements of motion in oil cylinder, cylinder moving power unit.In the process of piston rod movement, need to keep the two-way series sealing, therefore, use seal ring more.But because existing seal ring back pressure phenomenon in use, seal ring is easy to cause distortion, affects the sealing effect of piston rod.
The model utility content
The purpose of this utility model is to provide a kind of axle to affect the problem of rod seal effect because of distortion with the seal ring under the back pressure condition in the solution prior art with seal ring.
For solving the problems of the technologies described above, the utility model provides a kind of axle seal ring, comprises seal ring and back-up ring, and described seal ring inboard is provided with laterally zygomorphic sealing lip, and described back-up ring is embedded in described sealing lip and with described seal ring and is fixedly connected with.
As preferably, described seal ring is made by rubber-plastics material.
As preferably, described back-up ring is made by teflon.
Compared with prior art, the utlity model has following advantage: axle comprises seal ring and back-up ring with seal ring, and the inboard of described seal ring is provided with laterally zygomorphic sealing lip, and described back-up ring is embedded in described sealing lip and with described seal ring and is fixedly connected with.Axle is enclosed within on the piston rod with seal ring, when piston rod is worked, described axle is with the two ends effect of being stressed of seal ring, therefore the stressed to the inside extruding of described seal ring, state piston rod so that sealing lip is close to the residence, make axle reach sealing effect with seal ring, and described back-up ring works the described seal ring effect of supporting, avoid sealed ring deformation, simultaneously auxiliary seal.
Description of drawings
Fig. 1 is the cross-sectional schematic that the utility model one specific embodiment axis is used seal ring;
Fig. 2 is the structural representation that the utility model one specific embodiment axis is used seal ring.
Among the figure: 1-seal ring, 2-back-up ring, 3-sealing lip.
Embodiment
Below with reference to accompanying drawings the utility model is described in more detail, has wherein represented preferred embodiment of the present utility model, should be appreciated that those skilled in the art can revise the utility model described here and still realize advantageous effects of the present utility model.Therefore, following description is appreciated that extensively knowing for those skilled in the art, and not as to restriction of the present utility model.
For clear, whole features of practical embodiments are not described.In the following description, be not described in detail known function and structure, the confusion because they can make the utility model owing to unnecessary details.Will be understood that in the exploitation of any practical embodiments, must make a large amount of implementation details to realize developer's specific objective, for example according to relevant system or relevant commercial restriction, change into another embodiment by an embodiment.In addition, will be understood that this development may be complicated and time-consuming, but only be routine work to those skilled in the art.
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.It should be noted that the utility model accompanying drawing all adopts the form of simplification and all uses non-accurately ratio, only in order to convenient, aid illustration the utility model embodiment's purpose lucidly.
Please refer to Fig. 1, and in conjunction with Fig. 2, the utility model provides a kind of axle seal ring, comprises seal ring 1 and back-up ring 2, the inboard of described seal ring 1 is provided with laterally zygomorphic sealing lip 3, and described back-up ring 2 is embedded in described sealing lip 3 and with described seal ring 1 and is fixedly connected with.Concrete: axle is enclosed within on the piston rod with seal ring, and when piston rod work, described axle was with the two ends effect of being stressed of seal ring, and described seal ring 1 is stressed to be pushed to the inside, so that sealing lip 3 hugs piston rod, reaches the effect of sealing; Described back-up ring 2 plays a part to support seal ring 1, avoids seal ring 1 distortion, simultaneously auxiliary seal.
As preferably, described seal ring 1 is made by rubber and plastic (RP) material, and rubber-plastics material environmental protection, quality are light, have good pliability, and with low cost, and the seal ring 1 in the utility model can play good oil sealing effect.
As preferably, described back-up ring 2 is made by teflon.Teflon has good chemical stability, still can work under the high temperature and high pressure condition, and therefore, axle of the present utility model at condition of high voltage, in hydraulic oil container, still can play seal action with seal ring.
In sum, the utility model provides a kind of axle seal ring, comprises seal ring 1 and back-up ring 2, and the inboard of described seal ring 1 is provided with laterally zygomorphic sealing lip 3, and described back-up ring 2 is embedded in described sealing lip 3 and with described seal ring 1 and is fixedly connected with.Concrete: axle is enclosed within on the piston rod with seal ring, when piston rod is worked, described axle is with the two ends effect of being stressed of seal ring, therefore described seal ring 1 stressed to the inside extruding, state piston rod so that sealing lip 3 is close to the residence, thereby make axle reach sealing effect with seal ring, and described back-up ring 2 works described seal ring 1 effect of supporting, avoid seal ring 1 distortion, simultaneously auxiliary seal.
Obviously, those skilled in the art can carry out various changes and modification to model utility and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these revise and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these change and modification.
