Embodiment:
For example the utility model is done more detailed description below in conjunction with accompanying drawing:
The utility model comprises six links that are installed on the main frame structure, six metal-rubbers.Because metal-rubber can only bear the pressure-acting of forming direction, when vibration isolator was subject to the pressure-acting of direction from top to bottom, the metal-rubber of vibration isolator bottom of device began to work, and vibration isolator has played the effect of vibration damping.During vibration isolator top under tension, by the extruding of link to upper metal rubber, the metal-rubber on top begins to work, and vibration isolator has been played the effect of vibration damping.The particularity of this model utility is other four metal-rubbers.These four keys that metal-rubber is the three-dimensional vibration damping have realized the effectiveness in vibration suppression of direction all around.As shown in Figure 1, four metal-rubbers are distributed in four direction, take the vibration of fore-and-aft direction as example, these two metal-rubbers are squeezed, and produce the support force opposite with direction of vibration, and vibration amplitude is reduced, and in this process, absorbed energy, thereby the effect of generation vibration damping.But, actual three-way vibration is except above-below direction, selection on circumferential direction is at random, four direction all around not necessarily, so in fact it partly is continuous at the link that makes progress in week to this vibration isolator when realizing, guarantee vibration isolator three-dimensional vibration damping in actual use.
This is a kind of small-sized, has the vibration damping equipment of very large flexibility, and it can be used as a damping means and is installed in other large-scale vibration damping equipments, perhaps by a plurality of this vibration damping equipment combinations, realizes the three-dimensional vibration damping of main equipment.This metallic rubber vibration isolator link is many, and is easy to realize that the simplest method is exactly interpolation screw thread on link, cooperatively interacts, and connects very convenient cooperating of other devices.
The utility model can also comprise:
1. the core component of vibration isolator device is six metal-rubbers.The used metal-rubber of this device is of universal significance, as long as can guarantee suitable hollowly, being installed in main body frame and the link does not have the space, and the maintenance metal-rubber has certain precharge pressure.
2. before and after the vibration isolator device comprises up and down, different structure divisions, quick detachable.When only needs are unidirectional or two-way in the actual conditions, do not need whole installations, avoided redundancy.Improved efficient.
3. satisfying in the situation of above condition, different operating modes adopt different metal-rubbers.Six metal-rubbers are arranged with centrosymmetric form, and are identical in twos, and its concrete selection is carried out according to the requirement of three-dimensional vibration damping.For the demanding direction of effectiveness in vibration suppression, can select the good metal-rubber of energy-absorbing effect; For the high direction of rigidity requirement, can select the good metal-rubber of rigidity condition; Other situations are similar.
4. this isolation mounting can be used as the part of integral vibration isolation, by the combination assembling of a plurality of this kind isolation mountings and the cooperation of other relevant damping means, forms large-scale three-dimensional vibration damping equipment.
Metal-rubber can only bear the pressure-acting of forming direction, and when vibration isolator was subject to the pressure-acting of direction from top to bottom, vibration isolator device top connected vibration source, bottom connection device.Pressure is delivered on the main frame structure by the connecting rod on top, is delivered to the connecting rod of lower end by main body frame, and the metal-rubber of the connecting rod of lower end and main body frame bottom begins to work, and vibration isolator has played the effect of vibration damping.During vibration isolator top under tension, by the extruding of link to upper metal rubber, the metal-rubber on top begins to work, and vibration isolator has played the effect of vibration damping.For the three-dimensional vibration damping, it is similar in fact to grant aforesaid way.
Can find out vibration isolator device easy accessibility by three-dimensional vibration isolation apparatus exploded view.Only need up and down in the actual conditions and about effectiveness in vibration suppression the time, only need to install down in theory and about link and metal-rubber, so both saved the space, improved again efficient.But a problem in fact at this time occurred, this is the problem that can not run into when the individual event up-down vibration.When only having up-down vibration, remove four circumferential metal-rubbers, then follow the prescribed order and reinstall vibration isolator and just can reach the effect of vibration damping; But have at the same time up and down and during the vibration of left and right sides both direction, if remove pair of metal rubber and the corresponding link of circumferential fore-and-aft direction, so just must make the direction that metal-rubber is arranged about vibration isolator just aim at the direction at vibration place, this is to be difficult to realize in actual applications.In order to address this problem, can make amendment to circumferential link, make the plane arc shape that becomes of its front end.When plane, only have when power is vertical with the plane, could well pass to metal-rubber to power; When power and plane tilted at an angle, the effectiveness in vibration suppression of same metal-rubber was had a greatly reduced quality.When arc shape, vibration source to the power of link can perpendicular to arc shaped surface certain a bit.So, could can not be fine during the direction at aligning vibration place in the left and right sides of vibration isolator vibration damping direction, keep good effectiveness in vibration suppression.
