Abstract
It the utility model is related to a kind of damping sealing equipment.Purpose is to provide a kind of rubber-based abnormity damping seal ring, and the sealing ring should have the characteristics of performance is good, intensity is high, service life is long and energy-conserving and environment-protective and moulding process are simple.Technical scheme is：A kind of rubber-based abnormity damping seal ring, including the profiled metal skeleton of ring-type and the damping sealing ring layer for being wrapped in profiled metal skeleton surface；It is characterized in that：The inner circumferential surface of the profiled metal skeleton is provided with the projection around circumferencial direction, and at least twice annular recess is laid with projection；The damping sealing ring layer is provided with the ring-type raised line being embedded in by hot pressing in annular recess.
Description
Technical field
It the utility model is related to a kind of damping sealing equipment, specifically a kind of sealing ring for damping sealing field.
Background technology
Rubber-based damping sealing material is various kinds of equipment and the essential material of device, rubber-based damping sealing material
Performance is directly connected to the safety and stability of relevant device with quality；Once rubber-based damping sealing material failure, will
There is " three leakages " phenomenon of " leak, gas leakage, oil leak ", not only compromise surrounding environment, and easily cause the accident.
With the quickening of scientific and technological progress speed, all kinds of device performances are continuously available raising, to rubber-based damping sealing material
The diversity of material, complexity and the demands such as high-performance, long life certainly will be increased.But existing rubber-based damping sealing
The following defect of material generally existing：
1st, product is stretched, stretches that tearing toughness is low, and compression set amount is big surely；
2nd, complex forming technology, scrappage is high, causes the waste of raw material；
3rd, vibration-damping radiating poor performance, it can not continuously work in high temperature environments, have impact on service life.
Utility model content
The purpose of this utility model is overcome the shortcomings of in above-mentioned background technology, there is provided a kind of rubber-based abnormity damping sealing
Circle, the sealing ring should have the characteristics of performance is good, intensity is high, service life is long and energy-conserving and environment-protective and moulding process are simple.
Technical scheme provided by the utility model is：
A kind of rubber-based abnormity damping seal ring, including the profiled metal skeleton of ring-type and it is wrapped in profiled metal skeleton
The damping sealing ring layer on surface；It is characterized in that：The inner circumferential surface of the profiled metal skeleton is provided with around circumferencial direction
Projection, be laid with least twice annular recess in projection；The damping sealing ring layer is provided with recessed by hot pressing insertion ring-type
Ring-type raised line in groove.
The outline of the damping sealing ring layer is trapezoidal.
The beneficial effects of the utility model are：
Due to mutually chimeric by annular recess between profiled metal skeleton of the present utility model and damping sealing ring layer, no
But tensile strength is improved, elongation rate of tensile failure and tearing strength have also obtained significantly improving, and compression set is notable
(only 5~6%) are reduced, and service life is grown, and is entirely capable of the needs for meeting current client；In addition, the utility model produces
Technique is simple and does not produce waste material, has significant effects of energy conservation and environmental protection, has wide market prospects.
Brief description of the drawings
Fig. 1 is the main structure diagram of the utility model embodiment.
Fig. 2 is the overlooking the structure diagram of the utility model embodiment.
Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail, but the utility model not office
It is limited to following examples.
Rubber-based abnormity damping seal ring shown in figure, including profiled metal skeleton 1 (preferably steel skeleton) and parcel
Damping sealing ring layer 2 on profiled metal skeleton surface.
The profiled metal skeleton is ring-type, and the inner circumferential surface of profiled metal skeleton is provided with around the prominent of circumferencial direction
It is (visible in figure to play 1-1：The projection is symmetrically laid in the inner circumferential surface of profiled metal skeleton), at least twice are laid with projection
Annular recess 3；The damping sealing ring layer is provided with the ring-type raised line in the insertion annular recess formed by hot pressing.
The damping sealing ring layer be wrapped in by rubber injection technique profiled metal skeleton surface (also it is fully wrapped around live
Annular recess in projection and inner peripheral surface), therefore damping sealing ring layer is firmly bonded on profiled metal skeleton, not only product
Combination property has obtained greatly being lifted, and moulding process is simple, production cost is relatively low.
Claims (2)
1. a kind of rubber-based abnormity damping seal ring, including the profiled metal skeleton (1) of ring-type and it is wrapped in profiled metal bone
The damping sealing ring layer (2) on frame surface；It is characterized in that：The inner circumferential surface of the profiled metal skeleton is provided with around circumference
The projection (1-1) in direction, at least twice annular recess (3) is laid with projection；The damping sealing ring layer, which is provided with, passes through heat
The ring-type raised line being press-fitted in annular recess.
2. rubber-based abnormity damping seal ring according to claim 1, it is characterised in that：Outside the damping sealing ring layer
Profile is trapezoidal.
