Description
Technical field
The utility model relates to a kind of rubber absorbers.
Background technique
Rubber absorbers have been widely used in all kinds of machineries, automobile, railway locomotive, marine equipment, aircraft and other aircrafts as the important damper element of a class.Can say, the place that every needs are used damping and shock insulation all needs to use rubber absorbers.Why rubber absorbers are so used widely, are because it has effectively utilized following many characteristics of rubber:
1) rubber has high elasticity and viscoelasticity; Can satisfy the requirement of the Rigidity and strength of different direction, its internally-damped effect is larger than steel spring, and can be every the excitation frequency that is low to moderate about 10 hertz.
2) compare with iron and steel material quality, the resiliently deformable of rubber is very large, and Young's modulus is very little.
3) shock stiffness of rubber is greater than dynamic stiffness, and dynamic stiffness is conducive to reduce blastic deformation and dynamic deformation again greater than quiet rigidity.
4) load-deformation curve is oval hysteresis line, and its area equals the energy (damping) that shakes that each vibrations periodic transformation is heat, can adjust it by formula Design.
5) rubber is incompressibility material (Poisson's ratio is 0.5).
6) the rubber shape can freely be selected, and hardness can be adjusted by formula Design.
But also there is very large shortcoming in rubber absorbers: having used of a specified duration can be aging, and has larger creep (especially when high temperature) under heavy duty, so should not be subjected to surpass the continuous deformation of 10～15% (pressurizeds) or 25～50% (shears).
Its internal core components and parts of the machine that uses in the existing vibration environment are worth higher, shock resistance is relatively poor, very easily damage, existing glissando all is by installing rubber absorbers additional in the complete machine outside to whole machine damping mostly, but because complete machine weight is large, and the fully sudden and violent leakage of vibration damper externally, be easy to damage because of aging or overburden, vibration damper is ineffective and cause the damage of machine, and the shell of machine must be rigidly connected with fixed plate in a lot of situations, can't mounting shock absorber, this has just brought great narrow limitation for its use.This is the existing deficiency of prior art.
Summary of the invention
The utility model directly provides a kind of rubber absorbers that are exclusively used in the device interior components and parts for the device interior components and parts, solves the problem that can't mounting shock absorber causes internal component to damage because of exterior vibration because of complete machine.

Embodiment
Simply show a kind of mounting structure of electronic parts and components 2 of key with reference to the attached Fig. 1 and 2 of explanation, four jiaos of supports, electronic parts and components are stated from the circuit board usually, show as components and parts fixed plate 3 as shown in Figure 1.
A kind of based on device interior components and parts rubber absorbers of the present utility model for clearly describing in the content below, use state as reference with illustrated in figures 1 and 2, as rubber absorbers, it comprises:
And then, about Rubber shock-absorbing pad 5, for external member is placed on the described elastic axis 4 coaxially, and located by described position structure, and the axisymmetric device installation locating slot that is provided with in these Rubber shock-absorbing pad 5 sides, as shown in Figure 3.
Then matching fastener is to be fixed described elastic axis 4 via described fixed hole.
At first about the basic structure of elastic axis 4, be expressed as rigid pipe in above-mentioned content, it fixedly shows as a kind of rigidity so, makes mounting structure have relative stability.As for described position structure, should satisfy the location of described Rubber shock-absorbing pad 5, need to consider problem here, at first Rubber shock-absorbing pad 5 self has certain elasticity, its with have certain anticreep ability cooperating of elastic axis 4, but certain axial pressure is preferably arranged, and the axial freedom of a pair of Rubber shock-absorbing pad 5 retrains.Simultaneously this constraint does not preferably produce excessive impact to its elasticity.
As shown in Figure 3, bead is contained in the upper end of elastic axis 4, and bead in the expression forms the axial constraint to Rubber shock-absorbing pad 5, and is more attractive in appearance in order to make profile, and more compact structure, and Rubber shock-absorbing pad 5 upper ends are formed with counterbore, are used for holding described upper bead.
In some applications, described position structure is to be formed on the upper bead of elastic axis 4 upper ends and to be formed on the lower bead of elastic axis lower end, and in elastic axis 4 footpaths upwards the size of bead greater than the size of lower bead.This structure not only is conducive to the installation of Rubber shock-absorbing pad 5, and can form reliable axial constraint, and especially the upper end requires preferably constraint, can be according to the size of bead on the requirements set of oneself.
Preferably, described elastic axis and described Rubber shock-absorbing pad are the centrosymmetric structure about its axle, accordingly, hole centered by the described fixed hole, and described locating slot is annular groove, and the electronic parts and components 2 in the general device are all smaller, adopt simple supporting structure to get final product, thereby, Rubber shock-absorbing pad 5 just there is not the requirement of labyrinth.Naturally in some applications, as cooperating the fixing occasion of pair of screws, need to adjust dependency structure.
In certain embodiments, one side of described elastic axis and described Rubber shock-absorbing pad or be the plane about axisymmetric bi-side, this structure forms profile with the mounting hole of components and parts fixed plate 3 and cooperates, and prevents in the process of screw 6 pretensions, drives Rubber shock-absorbing pad 5 and rotates.
It is that profile connects (profile shaft connection) that profile cooperates, and its definition at mechanical field is: utilize the axle of non-round section and connecting of corresponding hub bore formation, based on this, those skilled in the art should have clearly understanding.
To be described locating slot form relevant for two fan annular grooves of elastic axis axis symmetry the another kind of structure that the coupling profile connects, and the two ends of two fan annular grooves are corresponding to be linked by two straight troughs.
