Abstract
A shock isolator comprises a damping device between a vibroseis and an object to be protected, which is characterized in that, a pair of foundation plates are positioned at one side of the vibroseis and the object to be protected respectively, two ends of a set of arc elastic parts are connected with two foundation plates. The utility model has the advantages that: 1. The rigidity in each direction surrounding 360 degree is of the same; 2. Dynamic amplification factor of unlubricated friction nonlinear damping is >3; 3. Dynamic effective alternative space of softening nonlinear rigidity is >70%; 4. Temperature scope: -75 DEG C to +175 DEG C, limiting temperature is +370 DEG C; 5. Easy installation, long service life and maintenance free.
Description
Technical field
The utility model relates to a kind of isolator, is used for protected instruments or equipment and vibratory source isolated.
Background technique
Existing isolator generally includes nonmetal damping (rubber) isolator, liquid and air damping isolator and spring shock-proof device, and they realize shock-absorbing, shock insulation function by the shock absorbing device that is located between vibratory source and the object of protection.Problem is that above-mentioned isolator or environmental adaptation scope are little, and the moving alternation useful space is little; Complex structure and manufacture cost height, structural limitations is moved alternation useful space minimum dimension, liquid damping (temperature) affected by environment; The substantially horizontal isolation property is unstable and install complicated.
The model utility content
The purpose of this utility model is to provide a kind of isolator, and it not only can realize rigidity such as 360 degree, and easy for installation, makes the life-span long, and is non-maintaining.
The technological scheme that realizes the utility model purpose is: a kind of isolator; comprise the shock absorbing device that is located between vibratory source and the object of protection; its distinctive feature is: have a pair of substrate that lays respectively at focus and object of protection one side, the two ends of one group of arc elastic part are connected with two substrates respectively.
And elastic part is a wire rope.
And elastic part is a spring steel plate.
The utility model has the advantages that: 1. around 360 the degree all directions on equal stiffness; 2. moving amplification factor＞3 of unlubricated friction nonlinear dampling; 3. soften the moving alternation useful space＞70% of type non-linear type rigidity; 4. loopful border adaptive temperature scope :-75 ℃ one+175 ℃, limiting temperature is+370 ℃; 5. easy for installation, make the life-span long, non-maintaining.
Description of drawings
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment
With reference to Fig. 1, Fig. 2; isolator described in the utility model; comprise the shock absorbing device that is located between vibratory source and the object of protection, its distinctive feature is: have a pair of two ends 2 that lay respectively at 1, one group of arc elastic part 3 of substrate of focus and object of protection one side and be connected with two substrates 1 respectively.
Further technological scheme can be: elastic part 3 is wire rope.The wire rope of making elastic part 3 can every 2 elastic part (see figure 2)s of formation after bending.Obviously, also can be steel cable back and forth continuously bending and constituting partly and even whole elastic parts 3 at two substrates, 1 place.
Described elastic part 3 can also be a spring steel plate.
