Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of sealing ring of this utility model；
The labelling implication of accompanying drawing is as follows:
1: caulking gum；2: ring packing spring；3: external diameter rubber layer；4: metallic framework；5: support member；Seal at 6: the first
Portion；7: the second sealings；8: breach.
Detailed description of the invention
With specific embodiment, technical solutions of the utility model are described in further detail below in conjunction with the accompanying drawings, so that
Those skilled in the art can be better understood from this utility model and can be practiced, but illustrated embodiment is not as to this reality
With novel restriction.
A kind of sealing ring, as it is shown in figure 1, include that metallic framework 4, ring packing spring 2(can also be the iron wires of annular
Circle) and caulking gum 1, it being provided with external diameter rubber layer 3 outside described metallic framework 4, the outer surface of described external diameter rubber layer 3 is arranged
Having groove, described caulking gum 1 is arranged on inside sealing ring, and one end (left end in Fig. 1) of described caulking gum 1 is provided with use
The first sealing 6 and the other end (right-hand member in Fig. 1) in clamping also sealing metal skeleton 4 are provided with for clamping sealing ring
Second sealing 7 of shape Packing spring 2, the inner side of described metallic framework 4 is provided with the support member 5 fitted tightly.
Caulking gum 1 has elastic nature, and countershaft have goodish sealing effectiveness, and metallic framework 4 can be iron material matter bone
Frame, increases rigidity and makes sealing ring to deform easily, and ring packing spring 2 provides the certain binding force of caulking gum 1 and extends close
In the service life of seal, the design of external diameter rubber layer 3 with groove makes assembling be easier to.
Support member 5 provides sealing ring rigidity to replace the function of bearing, it is preferable that described support member 5 is plastic supporting pieces 5, institute
State support member 5 and be provided with the breach 8 engaged with metallic framework 4.
Sealing ring is applied in rotary motion occasion, can have the characteristic of oil sealing and bearing concurrently, and external diameter rubber strip trench design makes
Must assemble easier, be particularly suitable for the pilot hole of high thermal expansion coefficient material, fixing moulding is set in the inner side of sealing ring
Material support member so that it is be supported between hole and axle, reduces the beating of axle, it is adaptable to the diameter of axle is beated big environment, can reduce and beat
Amount, improves sealing effectiveness.
These are only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
Utilize equivalent structure or equivalence flow process conversion that this utility model description and accompanying drawing content made, or directly or indirectly transport
It is used in other relevant technical fields, is the most in like manner included in scope of patent protection of the present utility model.
