Description
Technical field
The utility model is related to a kind of metal rubber shock absorbers of bellows support.
Background technology
Metal rubber shock absorber has many advantages, such as good high and low temperature resistance and corrosion resistance, Flouride-resistani acid phesphatase, and there is prodigious engineering to answer
With value.It is now widely used for the fields such as the tips such as aerospace, nuclear submarine military technology.Common damper at all can not
It is used for a long time in high temperature and pressure, the severe harsh working environment such as corrosive environment and irradiation, in the presence of a harsh environment common material
It is easy embrittlement, hardening, or even the dangerous situation that material property rapid drawdown is even failed occurs, effectiveness in vibration suppression is not only not achieved, can also
Influence the life security of working equipment and personnel.On the other hand, existing bellows absorber designing is various informative, is wanted in vibration damping
It can be met the requirements in the case of asking not high, but may result in the deficiency of damping property in the case where damping requirements are relatively high.
Existing bellows damper is mostly installed between two pipelines, on the one hand plays connection function, on the other hand
Play vibration reduction and cushioning.And the technical solution of generally use is the gold for being encased inside size therewith in the ripple hole of bellows and matching
Belong to rubber block, then uses locked clip device outside.The defect designed in this way is that when damper is by axial load impacting,
It can achieve the effect that vibration damping, but this technical solution can only realize the vibration damping in compression, when bellows damper is in axis
To the effect that cannot play vibration damping when stretching.And since metal-rubber is that a stick one stick is embedded in bellows,
Entire metal-rubber is not an entirety, when by axial load impacting, the phenomenon that being susceptible to unbalance stress, so subtracting
Effect of shaking is less desirable, and damping property requirement is often not achieved.
Invention content
It is compact-sized the purpose of this utility model is to provide a kind of metal rubber shock absorber of bellows support, overcome
Damper can not be used for a long time under the severe harsh working environment such as high temperature, low temperature and corrosive environment, irradiation and vibration damping is imitated
The undesirable defect of fruit.
The technical solution of the utility model is：A kind of metal rubber shock absorber of bellows support, including both ends difference
It is provided with the bellows of mounting flange, ripple size bellows identical with bellows ripple size is equipped with outside the bellows
Shape metal-rubber, the metal-rubber are equipped with Corrugated metal pipe sleeve outside, and the Corrugated metal pipe sleeve is square along its length outside
Several clips are installed to interval.
Further, the ripple's depth of the bellows-like metallic rubber is equal with waviness width.
Further, be equipped with along its length outside the Corrugated metal pipe sleeve positioned at both ends clip and be located at
The clip in portion, the clip are fixed on through fastening bolt outside Corrugated metal pipe sleeve.
Further, the mounting flange at the bellows both ends has the pipe of ring flange through fixing bolt and end set respectively
Road is fixedly connected.
Compared with prior art, the utility model has the following advantages：1. the metal-rubber vibration damping of bellows support
Device is compact-sized, and overcoming damper can not be long under the severe harsh working environment such as high temperature, low temperature and corrosive environment, irradiation
The defect that phase uses and effectiveness in vibration suppression is undesirable；And big damping characteristic does not change with temperature, long lifespan in harsh environment, surely
Qualitative height.
2. the vibration reduction and cushioning suitable for each type high temp, low temperature and corrosivity, radiation environment, and because it is with as rubber
High resiliency, big damping characteristic and the excellent physical mechanical property of metal, can be used for the pipeline of rocket engine, in instrument room
Instrument, the equipment in inertial navigation system and spacecraft solar array vibration reduction and cushioning.
3. vibration reduction and cushioning when compression and stretching in the axial direction not only may be implemented in practical engineering application to make
With, moreover it is possible to playing the role of certain vibration reduction and cushioning from radial shock loading, certain guarantor is played to entire vibration insulating system
Shield acts on.Most importantly when pipeline impact vibrated generates torsional deflection, bellows-sheathed can be transmitted with extraction duct
The torsional inertia come can be reversed with the torsion of pipeline, can dissipate vibrational energy, achieve the effect that vibration damping, to not
Pipeline can be caused to burst apart, entire nacelle is played a certain protective role.

Specific implementation mode
For allow the utility model features described above and advantage can be clearer and more comprehensible, special embodiment below, and coordinate attached drawing,
It is described in detail below, but the utility model is not limited to this.
Referring to figs. 1 to Fig. 3
A kind of metal rubber shock absorber of bellows support, including both ends are respectively arranged with the bellows 6 of mounting flange 61,
It is equipped with ripple size bellows-like metallic rubber 5 identical with bellows ripple size, the bellows outside the bellows
The ripple's depth H of shape metal-rubber is equal with waviness width D, and Corrugated metal pipe sleeve 2 is equipped with outside the metal-rubber, described
Interval is equipped with several clips 3 along its length outside Corrugated metal pipe sleeve.
Be equipped with along its length in the present embodiment, outside the Corrugated metal pipe sleeve positioned at both ends clip and be located at
The clip at middle part, the clip are fixed on through fastening bolt 4 outside Corrugated metal pipe sleeve.
In the present embodiment, the mounting flange at the bellows both ends has ring flange through fixing bolt 62 and end set respectively
1 pipeline 10 is fixedly connected.
Operation principle：When metal-rubber bellows damper is by from axial load force F1, ripple first
Pipe carries out crimp, and when active force gradually increases, the faces A of metal-rubber are squeezed deformation, wire spiral with the faces B
Friction occurs between wire turn, sliding, squeezes phenomenon, dissipate a large amount of vibrational energy, plays the role of vibration reduction and cushioning.When metal rubber
When glue bellows damper is by from radial load force F2, power is acted on first on Corrugated metal pipe sleeve, then
Metal-rubber is passed to, wire spiral wire turn is by occurring friction, sliding, extruding phenomenon after dynamic loading, then dissipate vibration
Energy.When the pipeline on submarine is due to by all kinds of weapon attackings such as torpedoes, pipeline is usually happens is that torsion becomes
Shape, at this time if using conventional metal pipe sleeve, pipeline can be collapsed by after torsional deflection.When using the present invention with
The Corrugated metal pipe sleeve of bellows matching size set, Corrugated metal pipe sleeve can be reversed with the torsion of pipeline, so as to
To dissipate vibrational energy, prevent the rupture of pipeline impaired, to protect the safety of nacelle.Since entire metal-rubber is one
It is whole, it will not there is a situation where unbalance stress, effectiveness in vibration suppression to greatly improve when by the load impacting of all directions.
The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the claims it is equal
Deng variation and modification, it should all belong to the covering scope of the utility model.
