Description
Technical field
The utility model relates to the vibration damping fields of equipment on moving base.
Background technique
On the motion carriers such as automobile, naval vessel or aircraft, some important equipment, such as guided missile, shell etc. are installed, this
A little equipment are connected on carrier often by mounting rack.Since the carrier movement time is long, vibration environment is to these equipment
Situations such as performance influence is very big, or even generation fatigue rupture, contact disconnect, part loosens leads to equipment performance decline, failure.
Therefore, reliable and effective damping technology, the performance for ensuring equipment are most important.
The equipment mounting frame often locating narrow space on carrier, load-bearing weight is big, vibration factor it is complicated (high and low frequency because
Element overlapping), working environment is severe, these factors all propose requirements at the higher level to the design of damper.Damping technology is main at present
Including rubber damping technology, wirerope damping technology, damping technology in parallel etc., there are easy to aging, frequency band is narrow, volume for these methods
Greatly, it bears a heavy burden the disadvantages of small, is difficult to meet the requirement of equipment vibration damping using single technical method, there is presently no effective
Damping technology scheme.
The utility model uses the combined vibration-damping technology of metal-rubber and metal spring, can successfully manage low frequency, high frequency
With the vibration conditions such as impact, and have many advantages, such as load-bearing greatly, high reliablity, service life it is long.
Utility model content
In view of the deficienciess of the prior art, the utility model provide it is a kind of compound based on metal-rubber and metal spring
Damper meets harsh damping technology requirement under the conditions of moving base.
The technical solution of the utility model is achieved in that a kind of combined vibration-damping based on metal-rubber and metal spring
Device, wherein metal-rubber consumes vibrational energy as resistance of shock absorber element to provide damping when damper work；Metal elastic
Spring provides rigidity as damper elastomeric element, for damper, for carrying.
Compound vibration-damper described in the utility model includes four metal-rubbers, two metal springs, a connecting pin, two
Shell, a bearing plate and a fastening nut；Compound vibration-damper is divided into damper and lower damper two parts, and every part is equal
It is made of a cylindrical screw metal spring and two metal-rubber elements, upper damper is located on connecting plate, lower damper position
Between connecting plate and pedestal.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1: compound vibration-damper structure and assembling schematic diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Attached drawing is compound vibration-damper structure and assembling schematic diagram.Damper is divided into damper and lower damper two parts,
Upper damper is located on connecting plate (2), and lower damper is located between connecting plate (2) and pedestal (3), solid by connecting pin (101)
It is fixed；Connecting pin (101) lower end is equipped with connection pin jack, and upper end is equipped with screw thread, matches with fastening nut (102)；Upper damper
It is made of with lower damper two metal-rubbers (103), a high-strength spring (104) and a protection shell (105)；Gold
Belonging to rubber (103) is cylindrical shape, is sleeved on connecting pin (101), high-strength spring (104) is sleeved on metal-rubber (103)
Periphery；It is limited by installation space, upper damper spring central diameter is slightly less than lower damper spring.Wherein, shell (105) surface layer is protected
It is used for anticorrosion by thermal spraying admiro, is avoided by external environmental.
According to the use environment condition of damper, the wire for preparing metal-rubber selects 304 austenite stainless steel materials,
Not only rubber organic non-metal material can have been overcome intolerant to high/low temperature, be easy the defect of fatigue aging, but also general carbon steel can be overcome
And the deficiency of other metal material poor corrosion resistances.
It generallys use in the past and stretches by hand or keep helical coil uniform to helical coil progress constant pitch by the method for calibration hole
It stretches, causes the helical coil screw pitch uniformity consistency after stretching poor, low efficiency, and it is more demanding to helical coil diameter accuracy.For
This realizes various string diameters and the close circle metal of coil diameter using a kind of screw roll fixed pitch stretching technique based on Electromechanical Control
The constant pitch Uniform Tension of silk helical coil.
Metal-rubber blank is using helical coil winding blank technology preparation, i.e., the helical coil after stretching constant pitch is according to one
Fixed winding path, which is wound on mandrel, is made blank.The technique accurately controls helical coil winding using numerical control blank Wiring apparatus
Motion profile solves the technical problem of metal-rubber product molding size and consistency of performance difference, and production efficiency is higher.
Metal-rubber and metal spring quilt when vertically being vibrated or impacting by dynamic excitation, in upper and lower damper
Repeated Compression and loosen, wherein metal-rubber, due to wire phase mutual friction, provides damping when bearing dynamic load, and consumption is vibrated
Energy plays damping element；Metal spring plays elastic element, provides rigidity for damper.In this way, in metal-rubber
Under the collective effect of metal spring, the purpose of vibration damping can be realized.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
