Description
Technical field
The invention belongs to seal manufacturing technology field in mechanical rotational transmission, and in particular to a kind of embedded with spring rotation
Rotating shaft lip-shaped sealed ring.
Background technology
There is the equipment manufacturing skill of liquid or gas conveying in large-scale engineering machinery equipment, oil, gas pipeline, transformer etc.
In art field, in order that machine internal cavity sealing effectiveness more preferably, prevents liquid or gas from leaking out, usually in mechanical fitting
Different sealing strip or sealing ring is accompanied between axially being docked with mechanical fitting, can make to reach inside at mechanical rotating parts
Cavity is sealed, and realizes sealing and conveying to liquid or gas.It is all rotating dress timing to be required for sealing gaskets such as V-type c-types
Circle carries out sealing docking, prevents junction poor sealing from causing gas leak of the oil leakage.Existing sealing ring uses homogenous material mostly, such as
Rubber seal.Rubber seal deforms to reach sealing machine device by process compresses, causes the rubber of homogenous material
Than larger, size is difficult to ensure that sealing ring internal stress, easily aging after use, and elasticity is deteriorated after deformation, coordinates lax, uses
The lost of life.When particularly being sealed to the surfaces of revolution, it is easiest to deformed damaged with the sealing ring of existing single material and comes off,
Poorly sealed between mechanical fitting so as to cause, replacement cost is increased.It is therefore desirable to propose to improve.
The content of the invention
Present invention solves the technical problem that：A kind of embedded with spring rotary shaft lip-shaped sealed ring is provided, the present invention by
The high score subclass elastomer of lip type structure adds endless metal skeleton and annular elastomeric spring coil, increases rubber seal itself and endures
Property, solve existing sealing ring be difficult to ensure that than larger, size using rear internal stress, easily it is aging, it is yielding damage and come off, become
The problem that elasticity is deteriorated, coordinates lax, service life to shorten after shape, with high resiliency, easily assembling, high intensity the features such as.
The technical solution adopted by the present invention：Embedded with spring rotary shaft lip-shaped sealed ring, including loop configuration macromolecule
Class elastomer, the high score subclass elastomer is that outer annular seal lip lower end and annular sealing lip lower end pass through annular lip bottom
The lip type structure for connecting and being formed, the outer annular seal lip and annular lip bottom internal of the high score subclass elastomer are provided with annular
Metallic framework, is provided with annular silicon rubber, the annular silicon rubber inside the annular sealing lip upper end of the high score subclass elastomer
Annular elastomeric spring coil is provided with inside glue.
Wherein, it is formed with the annulus being adapted to annular silicon rubber in the annular sealing lip top of the high score subclass elastomer
Shape through hole, it can be the pipe ring type of annular with annular through hole and the compound cross section of annular elastomeric spring coil that the annular silicon rubber is
Structure.
Further, the cross section of the endless metal skeleton is L-shaped structure.
Further, it is the main loop groove of U-shaped that cross section is formed between the outer annular seal lip and annular sealing lip,
Interior annular groove is provided with the inside of the annular sealing lip, the bottom of the annular sealing lip is provided with lower annular groove.
Present invention advantage compared with prior art：
1st, this programme is to add endless metal skeleton and annular elastomeric by the annular high score subclass elastomer in lip type structure
Spring coil, increases rubber seal itself very property, solves existing sealing ring and is difficult to protect than larger, size using rear internal stress
Card, easily aging, yielding damage and come off, deform after elasticity be deteriorated, coordinate the problem of lax service life shortening, with spy
The features such as high resiliency, easy assembling, high intensity, its internal stress is small, compressible in size, and use rear side facial disfigurement is small, and anti-side is to crowded
Go out small, long service life；
2nd, annular turn is covered by the high score subclass elastomer of annular in this programme, can effectively prevent annular elastomeric
Spring coil comes off, and improves the sealing ring property endured, lightweight, simple structure, and in the annular elastomeric spring coil and high score subclass elastomer between
Compound to be provided with annular silicon rubber, annular silicon rubber intensity is high, and wearability is good, ageing-resistant, can avoid annular elastomeric spring coil to high score
Subclass elastomer causes abrasion.

Specific embodiment
1-4 describes embodiments of the invention below in conjunction with the accompanying drawings.
Embedded with spring rotary shaft lip-shaped sealed ring, as shown in Figure 1,2,3, 4, including the high score subclass of loop configuration is elastic
Body 1, the high score subclass elastomer 1 is that the lower end of outer annular seal lip 101 and the lower end of annular sealing lip 102 pass through annular lip bottom
The lip type structure that portion 103 connects and formed, cross section is formed between the outer annular seal lip 101 and annular sealing lip 102
It is the main loop groove 105 of U-shaped, the inner side of the annular sealing lip 102 is provided with interior annular groove 106, the annular sealing lip
102 bottom is provided with lower annular groove 107.The outer annular seal lip 101 of the high score subclass elastomer 1 and annular lip bottom 103
Inside is provided with endless metal skeleton 2, and the cross section of the endless metal skeleton 2 is L-shaped structure.Wherein, high score subclass elastomer 1
And endless metal skeleton 2 can match various encapsulants and framework material, high score subclass according to using position and particular/special requirement
Elastomer 1 plays coating function, outward appearance is visually rubber seal, and endless metal skeleton 2 plays fixed dimension to sealing ring
Effect.
Annular silicon rubber 3, the annular are provided with inside the upper end of annular sealing lip 102 of the high score subclass elastomer 1
