Description
Technical field
The invention belongs to a kind of vibration damper, be specifically related to the vertical vibration damper of a kind of single rod annular air-pocket.
Background technique
Instrument particularly precision type instrument often all need be placed into a minimum working environment of vibration; People are through at instrument underlay one deck sponge mat or designed various " passive type vibration damper " and satisfied various instrument vibration damping; Like: one Chinese patent application number is that 2009100625007 " inflatable vibration damper " is exactly one of them; Although the compact structure of this inflatable vibration damper, rigidity is adjustable, because of it is to adopt to charge and discharge gas and regulate its damping property, therefore; Its damping property is regulated coarse, is difficult to be applicable to the demands of different of different instruments to vibration damping.
Summary of the invention
Regulate coarse deficiency in order to overcome existing inflatable vibration damper damping property, the present invention proposes the vertical vibration damper of a kind of single rod annular air-pocket.
Technological scheme of the present invention is following: the vertical vibration damper of a kind of single rod annular air-pocket; It comprises clutch release slave cylinder; Electromagnet, damping rod, a N annular air-pocket and N annular disc, wherein: the clutch release slave cylinder that is made up of non-magnet_conductible material is a cylindrical shape, all is fixed with end cap at the upper/lower terminal of clutch release slave cylinder; Center at upper end cap is porose, and sliding bearing is installed in the hole; Said N annular air-pocket and N annular disc that is made up of non-magnet_conductible material that is made up of macromolecular material is installed in the clutch release slave cylinder; Make the lower end of first annular air-pocket be fixed on lower end cap in the clutch release slave cylinder above; And then by an annular disc and annular air-pocket carry out overlapping and fastened to each other (that is: the lower end of first annular air-pocket be fixed on lower end cap in the clutch release slave cylinder above; Then; Fixing below the upper end of first annular air-pocket and first annular disc, to fix with the lower end of second annular air-pocket on above the annular disc at first, the following of the upper end of second annular air-pocket and second annular disc fixed; The following of the upper end of N-1 annular air-pocket and N-1 annular disc fixed, and top the going up with the lower end of N annular air-pocket of N-1 annular disc fixed, and N annular air-pocket upper end fixed with the following of N annular disc); N is natural number and is even number; One end of damping rod is fixed through the internal diameter of the annular disc of all odd numbers in the radial spoke that is made up of non-magnet_conductible material and the clutch release slave cylinder, and the external diameter of the annular disc of all even numbers is fixed on through the spoke that is made up of non-magnet_conductible material on the inner circumference of clutch release slave cylinder, and the other end of damping rod stretches out in clutch release slave cylinder through the bearing of clutch release slave cylinder upper end cap; The liquid level height that in clutch release slave cylinder, injects magnetic flow liquid will exceed N annular disc; Leave certain spacing between the upper end cap in the liquid level of magnetic flow liquid and the clutch release slave cylinder in the clutch release slave cylinder, electromagnet is fixed on the excircle of clutch release slave cylinder, on the upper end cap of clutch release slave cylinder, also is provided with at least one exhaust hole; Annular air-pocket is to constitute ring by macromolecular material; In annular air-pocket, be filled with the gas of certain pressure; The internal diameter of annular air-pocket is greater than the external diameter of damping rod and leave annular air-pocket distortion and the mobile gap of magnetic flow liquid; The external diameter of annular air-pocket is less than the internal diameter of clutch release slave cylinder and leave annular air-pocket distortion and the mobile gap of magnetic flow liquid; The internal diameter of annular disc is greater than the external diameter of damping rod and leave the gap that magnetic flow liquid flows, and the external diameter of annular disc is less than the internal diameter of clutch release slave cylinder and leave the gap that magnetic flow liquid flows; The internal diameter of annular disc is greater than the external diameter of damping rod and leave the gap that magnetic flow liquid flows, and the external diameter of annular disc is less than the internal diameter of clutch release slave cylinder and leave the gap that magnetic flow liquid flows, and also is provided with at least one exhaust hole on the upper end cap of clutch release slave cylinder.
Function of the present invention is achieved in that the vertical vibration damper of single rod annular air-pocket of the present invention adopts vertical installation; When load causes the downward vibration of damping rod; Damping rod will be through being fixed on the one of which end N/2 annular disc be fixed on N/2 annular disc acting in conjunction on the clutch release slave cylinder inner circumference; The annular air-pocket that is fixed between the annular disc is compressed or stretches, because of being filled with the gas of certain pressure in the annular air-pocket, and annular air-pocket is made up of macromolecular material; Therefore; Annular air-pocket will make annular air-pocket that distortion to a certain degree takes place being compressed or stretching, and the distortion of annular air-pocket will be pushed the magnetic flow liquid of (just in the clutch release slave cylinder) around it, and the annular air-pocket liquid level height that also can cause magnetic flow liquid in the clutch release slave cylinder that deforms changes; When the liquid level height of magnetic flow liquid in the clutch release slave cylinder changed, the air of magnetorheological liquid level top can be through the turnover of the exhaust port on the upper end cap in the clutch release slave cylinder; When the electromagnet on the clutch release slave cylinder excircle is not switched on; The viscosity of the magnetic flow liquid in the clutch release slave cylinder is very low; When load causes that damping rod vibrates downwards, damping rod make each annular air-pocket produce distortion and the damping force that produced when pushing the magnetic flow liquid of (that is: in the clutch release slave cylinder) around it less; After the electromagnet on the clutch release slave cylinder excircle feeds electric current; Electromagnet on the clutch release slave cylinder excircle will generate an electromagnetic field, and this electromagnetic field uprises the viscosity of the magnetic flow liquid in the clutch release slave cylinder, like this; When load causes that damping rod vibrates downwards; Damping rod make each annular air-pocket produce distortion and the damping force that produced when pushing the magnetic flow liquid of (that is: in the clutch release slave cylinder) around it just bigger, therefore, get into the size of current in the electromagnet on the clutch release slave cylinder excircle through adjustment; Can adjust the damping force size of the magnetorheological vertical vibration damper of single rod air sac type of the present invention; Thereby reduced the vibration of load, tell on is repeated no more with above-mentioned opposite here when load causes upwards vibrating of damping rod.
Compare with existing inflatable vibration damper; The vertical vibration damper of single rod annular air-pocket of the present invention; Because of not only coming continuously the rigidity of adjustment air bag to carry out " active damping " through the field current size of adjusting its electromagnet; But also can adjust its bearing capacity through the quantity of annular air-pocket and annular disc in the adjustment clutch release slave cylinder; Make it can be applicable to different vibration damping occasions and satisfy different instrument vibration damping demands, make the using scope of the magnetorheological vertical vibration damper of single rod air sac type obtain expanding.
