The central connecting part.Multiple apertures can be set in the periphery of the central through hole of built-in metal on piece, pre-buried for assisting realizing
Sheet metal is relative to the circumferentially positioned of central connecting part.Connect advantageously, the one or both ends of built-in metal piece are exposed at center
Except socket part 1, it is used as installation positioning surface.In one alternate embodiment, internal screw thread is provided on central through hole.It is installing
When, threaded connector passes through the mounting hole on hard disk shell and screws in central through hole.
Periphery interconnecting piece 2 with mounting bracket for connecting.In the present invention, " mounting bracket " refers to for installing hard disk
Pedestal, or the shelf being fixed on the pedestal or pallet etc..Periphery interconnecting piece 2 can connect with structure in any suitable manner
It is connected to mounting bracket.Optionally, periphery interconnecting piece 2 is connected to mounting bracket in the form of vulcanization.As shown in Fig. 2, from being parallel to
When the view of thickness direction, the periphery of the centrally disposed interconnecting piece 1 of periphery interconnecting piece 2, and between the two between radial direction
Gap.To which periphery interconnecting piece 2 and central connecting part 1 can do relative radial motion, to carry out vibration damping, absorb vibrational energy.
As shown in Figure 1, the central connecting part mutually staggers in a thickness direction with the periphery interconnecting piece, and it is described in
Heart interconnecting piece deviates relative to the periphery interconnecting piece to hard disk.
In a preferred embodiment, the outside wall surface of central connecting part 1 is cylindrical surface, and the inner wall of periphery interconnecting piece 2 is
Cylindrical surface, and the inner wall of the outside wall surface of central connecting part 1 and the periphery interconnecting piece 2 has common axis line.To, not by
In the case where power, there is uniform radial clearance between the outside wall surface of central connecting part 1 and the inner wall of periphery interconnecting piece 2.Even
The inner end for connecing arm 3 is connected to the outside wall surface of central connecting part 1, and the outer end of linking arm 3 is connected to the inner wall of periphery interconnecting piece 2,
And the quantity of the linking arm is multiple, and is circumferentially uniformly distributed.To have simple structure and preferable processing
Property, and there is uniform radial clearance between inner wall and outside wall surface, to adapt to and allow the deformation in all directions, to the greatest extent
Amount avoids the direct friction between inner wall and outside wall surface.
In an optional embodiment, the cross section of the outside wall surface of central connecting part 1 is rectangular, and is equipped with circle in corner portion
Angle, the inner wall of periphery interconnecting piece 2 are cylindrical surface.Each in four flat segments of the outside wall surface of central connecting part 1 is straight

3).For example, the weight ratio of the butyl rubber, stearic acid and zinc oxide is 100:8:2.Advantageously, in the rubber shock-absorbing
Further mixed with carbon black and vulcanizing agent in device.This advantageously allows to have in low frequency and high frequency compared with high-damping, and reduces high temperature 70-
The product aging rate in 90 DEG C of section.
In one embodiment, specifically formula and technological parameter are as follows.
One: raw material:
Two, it is formulated:
Three, technique
Butyl rubber is put on open mill and is plasticated 20 minutes, centre needs rolling uniformly to make thinner no less than 20 times, then draws
Big roll spacing sequentially adds stearic acid, zinc oxide, carbon black and auxiliary agent, thin 8-10 times logical, slice.In another technique, by fourth
Base rubber is placed on open mill, is first heated to 150 degrees Celsius of temperature, is kept pressure 150MPa, is plasticated 5 minutes；It is added stearic
After acid and zinc oxide, continue to plasticate 5 minutes；Then carbon black and suitable adjuvants (if necessary) are added, improve temperature to 180
Degree Celsius, pressure is improved to 175MPa, is plasticated 5-8 minutes, and rolling is made thinner no less than 10 times；Temperature and pressure is kept to continue later
It plasticates to slice forming slice.
Conditions of vulcanization: 180 degrees Celsius X 20 minutes, pressure 175MPa.
Characteristic based on rubber body, adaptive temperature range face is narrow, common after 60 DEG C, the property of damper
Shape will vary widely, and rubber generates after being cooled to be melted under cured changeable environment, and easily aging leads to vibration damping
Performance is had a greatly reduced quality.But passes through treated rubber, there is better performance.
