Abstract
A kind of O-shaped composite sealing ring of embedded with spring for axial Butt Assembling is provided, including central spring support, silastic-layer and macromolecular elastomer layer, central spring support two ends connect to form loop configuration, central spring rack outer surface is compound to be enclosed with silastic-layer, and silastic-layer outer surface is compound to be enclosed with macromolecular elastomer layer.The present invention uses spring supporting and the sealing ring being compounded to form with silicon rubber and macromolecular elastomer, can effectively solve the problem that the internal stress that the rubber seal that existing homogenous material is made is present be difficult to ensure that than larger, size, after use it is easy it is aging, after deformation elasticity be deteriorated, coordinate it is lax, yielding damage and come off, the problem that service life is short, can effectively prevent turn from coming off, sealing is tight between making mechanical part, reduces replacement cost.
Description
Technical field
The invention belongs to mechanical drive shaft air locking manufacturing technology field, and in particular to a kind of for axial Butt Assembling
The O-shaped composite sealing ring of embedded with spring.
Background technology
There are liquid or gas in EMUs, locomotive, transformer, sewing machine, automobile, motorcycle, petrochemical industry, high-voltage switch gear etc.
In the sealing industry of the equipment manufacturing technical field of body conveying, in order that machine driven system, sealing effect more preferably, prevent liquid
Body or gas leak, usually pad has the different sealing ring of different, material between axially docking, can make mechanical drive department
Office reaches cooperation cavity sealing, realizes the sealing and conveying to liquid or gas.It is all to be required for when assembling longitudinal axis using
Seal washer carries out sealing docking, prevents junction poor sealing from causing leakage gas leakage.Existing sealing ring is mostly using single
Material is made, such as rubber seal.Rubber seal deforms to reach sealing machine device by process compresses, causes single
Than larger, size is difficult to ensure that the rubber seal internal stress of material, easily aging after use, and elasticity is deteriorated after deformation, matches somebody with somebody
Close lax, service life shortens.When particularly being sealed to sagittal plane, deformation is easiest to the sealing ring of existing single material
Damage and come 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 O-shaped compound seal of embedded with spring for axial Butt Assembling is provided
Circle, the present invention uses spring supporting and the sealing ring being compounded to form with silicon rubber and macromolecular elastomer, can effectively solve the problem that existing
The internal stress of the rubber seal being made with the presence of homogenous material is difficult to ensure that than larger, size, after use it is easy it is aging, becoming
After shape elasticity be deteriorated, coordinate lax, yielding damage and come off, the problem that service life is short, can effectively prevent turn from taking off
Fall, sealing is tight between making mechanical part, reduces replacement cost.
The technical solution adopted by the present invention：For the O-shaped composite sealing ring of embedded with spring of axial Butt Assembling, including in
Heart spring support, silastic-layer and macromolecular elastomer layer, the central spring support two ends connect to form loop configuration, described
Central spring rack outer surface is compound to be enclosed with silastic-layer, and the silastic-layer outer surface is compound to be enclosed with macromolecular elastomer
Layer.
Wherein, the central spring support is the loop configuration for being connected using coil type spring two ends and being made.
Further, the silastic-layer forms cylinder structure by being wrapped in central spring rack outer surface, described
Macromolecular elastomer layer also forms cylinder structure, the He of cross section I of the silastic-layer by being wrapped in silastic-layer outer surface
The cross section II of macromolecular elastomer layer is cirque structure.
Present invention advantage compared with prior art：
1st, this programme is that it can using spring supporting and the sealing ring that is compounded to form with silicon rubber and macromolecular elastomer
Effectively prevent central spring bracket loop from coming off, macromolecular elastomer macromolecular material simultaneously can be according to use position and particular/special requirement
Various encapsulants are matched, being relaxed with Sealing Stress, small, elastic good, intensity is high, compressible in size, use rear side facial disfigurement
Small, anti-lateral extrusion is small, using rear non-aging, be unlikely to deform damage come off, the advantage of long service life；
2nd, the ring structure that this programme is made is simple, lightweight, low cost of manufacture, and sealing is tight between making mechanical part,
Reduce and change number of times, reduce replacement cost.

Specific embodiment
1-4 describes embodiments of the invention below in conjunction with the accompanying drawings.
For the O-shaped composite sealing ring of embedded with spring of axial Butt Assembling, including central spring support 1, silastic-layer 2
With macromolecular elastomer layer 3, as illustrated in fig. 1 and 2, the two ends of central spring support 1 connect to form loop configuration, the center
The outer surface of spring support 1 is compound to be enclosed with silastic-layer 2, and the outer surface of the silastic-layer 2 is compound to be enclosed with macromolecular elastomer
Layer 3, in process, it is also possible to first by silastic-layer 2 and macromolecular elastomer layer 3 it is compound after again with central spring support 1
It is combined with each other.Wherein, as shown in figure 3, the silastic-layer 2 forms pipe by being wrapped in the outer surface of central spring support 1
Type structure, the macromolecular elastomer layer 3 also forms cylinder structure by being wrapped in the outer surface of silastic-layer 2, as shown in figure 4,
The cross section II 5 of the cross section I 4 of the silastic-layer 2 and macromolecular elastomer layer 3 is cirque structure.Preferably, it is described
Central spring support 1 is made of coil type spring, and the coil type spring two ends connect to form loop configuration, the letter of its structure
Single, processing and manufacturing is easy.
The present invention is that it can have using spring supporting and the sealing ring that is compounded to form with silicon rubber and macromolecular elastomer
Effect prevents central spring support 1 from coming off, and molecular flexibility body layer 3 is with macromolecular material and can be selected according to using position and particular/special requirement
With various encapsulants, relax that small, elastic good, intensity is high, compressible in size, use rear side facial disfigurement is small with Sealing Stress,
Anti- lateral extrusion is small, using rear non-aging, be unlikely to deform damage come off, the advantage of long service life, simple structure of the present invention,
It is lightweight, low cost of manufacture, sealing is tight between making mechanical part, reduces and changes number of times, reduces replacement cost.
Above-described embodiment, simply presently preferred embodiments of the present invention, not for limiting the scope of the present invention, thus it is all with this
