Abstract
The present invention relates to a kind of wear-resisting bionical sealing rings of rotary dynamic seal.It can be used for static seal and rotary dynamic sealing structure, has excellent static seal and dynamic sealing performance, while wear-resistant, high temperature resistant, has good greasy property, reduce rubber seal and the failure phenomenons such as aging, abrasion, tearing occur in rotary dynamic seal.Its technical solution is：Rotary dynamic seal opens up the bionical slot of two row interlaced arrangements with the surfaces externally and internally of wear-resisting bionical sealing ring, is not connected to mutually between bionical slot, in bionical slot can lubrication oil, frictional contact surface is lubricated, is cooled down, and realizes wear-resisting anti-drag function.The sealing ring is applicable to the dynamic sealing system for the bad working environments such as high temperature, impurity is more.
Description
Technical field
The present invention relates to dynamic sealing field, the wear-resisting bionical sealing ring of especially a kind of rotary dynamic seal.
Background technology
Rubber seal is widely used in the dynamic of the fields such as machinery, petrochemical industry, traffic, aerospace, nuclear industry, ocean
Sealing structure, and the sealing performance quality of sealing ring is directly related to reliability and the safety of whole system.It is dynamic close in rotation
The relative motion of Feng Zhong, sealing ring and other component generates a large amount of heat, accelerates the aging of rubber seal, and severe ring
Impurity enters after sealing surface the wear out failure that will aggravate sealing ring surface in border.Thus, design is a kind of dynamic close suitable for rotation
The bionical sealing ring of heat resistant and wear resistant of envelope is of great significance.
Bionics Study finds that non-smooth surface has good wearability, drag reduction, lubricity, such as the crust of pangolin
Appearance, earthworm nodular limbs etc..To overcome sealing ring non-refractory in rotary dynamic seal, defect easy to wear, based on bionical
Non-smooth surface principle, the present invention devise a kind of wear-resisting bionical sealing ring of rotary dynamic seal, and sealing ring surfaces externally and internally opens up
Bionical slot, the sealing ring have good wearability, self sealss, lubricity, thermal diffusivity, can be applied to static seal and rotation is dynamic close
Envelope, greatlys improve the service life, reliability and safety of entire sealing system.
Invention content
The purpose of the present invention is：The problems such as to overcome in existing rotary dynamic seal rubber seal easy to wear, non-refractory,
Provide a kind of rotary dynamic seal wear-resisting bionical sealing ring, compared with existing sealing ring, more resistant, high temperature resistant, endurance.
To achieve the goals above, the present invention uses following technical scheme：A kind of wear-resisting bionical sealing of rotary dynamic seal
Circle, is made of sealing ring ontology, it is characterised in that sealing ring body outer surface opens up external bionical slot, and external bionical slot is close
Two row of seal body outer surface distribution and interlaced arrangement, sealing ring body internal surface open up internal bionical slot, and internal bionical slot exists
The two bionical slots of row of two row of sealing ring body internal surface distribution and interlaced arrangement, surfaces externally and internally are not connected to mutually, external bionical slot
With internal bionical slot can lubrication oil, frictional contact surface is lubricated, is cooled down, and realizes wear-resisting anti-drag function.
As further technical solution, the bionical slot in outside and internal bionical slot on the sealing ring body surface can
It is axially arranged in parallel or is in tilted layout using with sealing ring.
The beneficial effects of the invention are as follows：(1) the bionical slot that the surfaces externally and internally of the sealing ring opens up can lubrication oil, close
It can guarantee that sealing surface is in good lubrication state in seal rotational movement process；(2) the bionical slot on the sealing ring surface deposits lubrication
Oil can increase the heat dissipation performance of sealing ring, reduce since spin friction heat causes the aging of sealing ring, to more longlasting guarantee
The good seal performance of sealing ring improves its service life；(3) bionical slot can reduce its surface in sealing ring rotary motion
Frictional resistance improves wear-resisting property；(4) bionical slot can accommodate impurity, and sealing ring can will be between contact surface in rotary motion
Impurity is elapsed into bionical slot, reduces the abrasive wear on its surface.

Specific implementation mode
The invention will be further described with reference to the accompanying drawings and detailed description.
As shown in Figure 1, Figure 2 and Figure 3, the wear-resisting bionical sealing ring of a kind of rotary dynamic seal is by 1 structure of sealing ring ontology
At；1 outer surface of sealing ring ontology opens up external bionical slot 2, external bionical slot 2 arrange in 1 appearance EDS maps two of sealing ring ontology and
Interlaced arrangement, 1 inner surface of sealing ring ontology open up internal bionical slot 3, and internal bionical slot 3 is distributed in 1 inner surface of sealing ring ontology
The two bionical slots of row of two row and interlaced arrangement, surfaces externally and internally are not connected to mutually, and external bionical slot 2 and internal bionical slot 3 can be stored
Lubricating oil is lubricated frictional contact surface, cools down, and realizes wear-resisting anti-drag function.
As shown in Figure 1 and Figure 4, the bionical slot 2 in outside on 1 surface of sealing ring ontology and internal bionical slot 3 can be used with it is close
Seal axially parallel arrangement or inclination arrangement.
