Abstract
The invention discloses a high-performance seal ring comprising a body and an outer ring. An annular groove is arranged on the body in the circumferential direction, the outer ring is embedded in the annular groove of the body, mucilage glue is arranged between the body and the outer ring, and the body and the outer ring are manufactured by rubber materials with different components. According the high-performance seal ring disclosed by the invention, the structural design is reasonable, the performance is outstanding, and the rubber materials with different materials are adopted by the body and the outer ring so that different use performance is shown in the use process of the body and the outer ring. The shock resistance capability of the body is excellent, the additional outer ring has good wear and corrosion resistance performance, and the user performance and the service life of the seal ring are greatly improved by the unique structural design, therefore, the high-performance seal ring is more suitable for being used on a hydraulic cylinder piston rod.
Description
Technical field
The present invention relates to a kind of seal ring, relate in particular to a kind of hydraulic cylinder piston rod high-performance sealed circle, belong to the hydraulic fittings technical field.
Background technique
At present, the initial sealing in the oil hydraulic cylinder between piston rod and the hydraulic cylinder all is the extrusion-deformation that relies on seal ring in use to produce, and finishes sealing.This sealing means is all very high to size and the surface requirements of piston rod, and along with the creep of the continuous wearing and tearing of seal ring and sealing material and aging, positive pressure between piston rod and the seal ring will reduce gradually, so that the effect of initial sealing weakens gradually, finally cause seal failure.
Because seal ring is in selection and structural difference, its performance is often uneven, the seal ring that working life and durability are lower needs often to detect and change, and is arranged on the equipment inner seal ring that is subjected to the effect of larger hydraulic shock power for some, and the requirement of its wear resistance aspect tends to very high.The decline of seal ring usability tends to cause hydraulic system to occur leaking and disrepair phenomenon, reduces manufacturing efficiency, and can cause a hidden trouble to safety in production.Existing seal ring is all perfect not in the performance aspect usability and working life, is being still waiting further raising aspect its structure and material.
Summary of the invention
For the demand, the invention provides a kind of high-performance sealed circle, the sealing coil structures is reasonable in design, performance is outstanding, the impact resistance of its body is excellent, and the outer ring of setting up has given seal ring good wear-resisting property, has effectively promoted usability and the working life of seal ring.
The present invention is a kind of high-performance sealed circle, the sealing circle comprises body and outer ring, described body is offered annular groove along its circumferencial direction, described outer ring is nested in the annular groove of body, adopt viscose glue between described body and the outer ring, described body and outer ring are made by the rubber material of heterogeneity.
In a preferred embodiment of the present invention, described body is selected the rubber material of plasticity, good strength, the rubber material that the outer ring is selected is wear-resisting, corrosion resisting property is good.
In a preferred embodiment of the present invention, described body generally can be selected a kind of in nitrile rubber, butyl rubber, the hydrogenation nitrile rubber.
In a preferred embodiment of the present invention, a kind of in urethane rubber, nitrile butadiene rubber or the teflon rubber generally can be selected in described outer ring.
In a preferred embodiment of the present invention, described body produces resiliently deformable under action of hydraulic force, and this resiliently deformable can externally be enclosed the formation extruding force, makes the outer ring produce outwardly directed tendency, has guaranteed sealability good between outer ring and the hydraulic tube tube wall.
In a preferred embodiment of the present invention, be " W " type groove structure on the circumferential surface of described outer ring.
In a preferred embodiment of the present invention, the degree of depth of described annular groove is about the 30%-35% of body radial thickness, and its width is about the 80%-85% of body width.
The present invention has disclosed a kind of high-performance sealed circle, and the sealing coil structures is reasonable in design, and performance is outstanding, and the rubber material of unlike material is selected in its body and outer ring, makes both in use show different usabilities; The impact resistance of body is excellent, and the outer ring of setting up has good wear-resisting and corrosion resisting property, and this unique texture design has promoted usability and the working life of seal ring greatly, makes it be more suitable for using at hydraulic cylinder piston rod.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of embodiment of the invention high-performance sealed circle;
The mark of each parts is as follows in the accompanying drawing: 1, body, 2, the outer ring, 3, annular groove.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
Fig. 1 is the structural representation of embodiment of the invention high-performance sealed circle; The sealing circle comprises body 1 and outer ring 2, described body 1 is offered annular groove 3 along its circumferencial direction, described outer ring 2 is nested in the annular groove 3 of body 1, adopts viscose glue between described body 1 and the outer ring 2, and described body 1 is made by the rubber material of heterogeneity with outer ring 2.
The body 1 of the high-performance sealed circle that the present invention mentions is selected the rubber material of plasticity, good strength, and the rubber material wear-resisting, that corrosion resisting property is good is selected in outer ring 2; Body 1 generally can be selected a kind of in nitrile rubber, butyl rubber, the hydrogenation nitrile rubber; A kind of in urethane rubber, nitrile butadiene rubber or the teflon rubber generally can be selected in outer ring 2.
Body 1 produces resiliently deformable under action of hydraulic force, this resiliently deformable can form extruding force to outer ring 2, makes outer ring 2 produce outwardly directed tendency, has guaranteed sealability good between outer ring 2 and the hydraulic tube tube wall; Be " W " type groove structure on the circumferential surface of outer ring 2, this structure can be stored quantitative lubricant oil, reduces the wearing and tearing of outer ring 2, improves its working life.
The degree of depth of the annular groove 3 of offering on the body 1 is about the 30%-35% of body 1 radial thickness, and its width is about the 80%-85% of body 1 width, and this structural design can be guaranteed the associativity that outer ring 2 and body 1 are good; Adopt thermosetting viscose glue PVC or PU to bond between the two, binding ability is stable, and working life is lasting.
