Abstract
The invention relates to a single-sided magnetic suspension structure. According to the invention, a magnetic fluid is adsorbed to the surface of a strong magnet, and a suspension structure by means of the magnetic fluid can be generated when the strong magnet is contacted with the surface of a non-magnetic body. The structure realizes a simple and stable non-direct contact state between the strong magnet and the non-magnetic body by means of magnetic fluid contact. The magnetic fluid is of a liquid state, so that disturbance and friction between the two objects in relative motion are reduced. The single-sided magnetic suspension structure mainly has the characteristics that the size of friction is in positive correlation with the viscosity of the magnetic fluid; the magnetic fluid in any directions around a magnetic field of the strong magnet has a repulsive effect for the surface of the non-magnetic body; and the suspension capability and a repulsive force are in positive correlation with the magnetic field intensity of the strong magnet and the magnetic permeability of the magnetic fluid.
Description
Technical field
Patent of the present invention is a kind of one side magnetic suspension structure.A kind ofly specifically to be made up of kicker magnet, magnetic fluid and non-magnetizer, between three kinds of materials, suspension phenomenon can to occur, possess when kicker magnet and non-magnetizer to have the structure of minimal friction in magnetic fluid generation relative movement thereof simultaneously.
Background technology
Magnetic suspension structure refers to that two magnets with magnetic field of the same name repel the noncontact rock-steady structure of rear formation mutually mostly.Object can be formed and be suspended in aerial phenomenon and contactless relative motion mode.The excellent specific properties such as frictional force only depends on air drag under relative motion modes, and kinetic energy efficiency is high.But one among a small circle in form one and can the stable double-side magnetic of relative motion suspend more difficult, complex structure, practical value is not high.
Summary of the invention
The problem that patent of the present invention solves overcomes the deficiency in background technology.Utilize kicker magnet and non-magnetizer by the intervention of magnetic fluid, construct and can produce one side magnetic suspension phenomenon, and possess the structure having small frictional force between contact-making surface.
The discovery 1 of patent of the present invention is, must be that kicker magnet, non-magnetizer and magnetic fluid exist simultaneously, because magnetic fluid is adsorbed on around surface, kicker magnet magnetic field by kicker magnet magnetic field suction, define between kicker magnet and non-magnetizer contact-making surface a liquid have certain fluidity and can flexible magnetic fluid elastic layer under external force.Non-magnetizer surface and kicker magnet surperficial between due to the existence of magnetic fluid elastic layer, define maglev phenomenon in the direction perpendicular to ground, that is kicker magnet can float over non-magnetizer be bottom surface magnetic fluid above or non-magnetizer be suspended in magnetic conductor be bottom surface magnetic fluid above.This levitation effect to be attracted by kicker magnet Surface field due to magnetic fluid and is strapped in around kicker magnet surface, non-magnetizer surface does not have magnetic field, only play a supporting role, the field of magnetic forece relying on the magnetic field of kicker magnet itself to be showed by magnetic fluid produces repulsive interaction phenomenon to non-magnetizer surface, so be a kind of one side magnetic suspension structure.
The discovery 2 of patent of the present invention is, the magnetic fluid elastic layer of this structure can be wrapped in centre kicker magnet, all there is repulsive interaction to close non-magnetizer surface in any direction, namely can produce one side magnetic suspension effect to comprehensive close non-magnetizer surface, the size of this repulsive force becomes positive correlation with the size of kicker magnet Surface field intensity with the height of magnetic fluid permeability, becomes inverse correlation with kicker magnet with the gap length of non-magnetizer contact-making surface simultaneously.
The discovery 3 of patent of the present invention is, because one of characteristic of magnetic fluid has good lubrication effect in this structure, and magnetic fluid elastic layer is fixed on around kicker magnet surface under the constraint in kicker magnet magnetic field, and within the scope of high-intensity magnetic field, have certain mobility, so when kicker magnet and non-magnetizer do relative motion along contact-making surface, magnetic fluid elastic layer can move along with kicker magnet always, is maintained between their contact-making surfaces, so only have small frictional force in this relative movement.The size of frictional force depends primarily on magnetic fluid viscosity and air drag.
Above-mentioned discovery, be all the magnetic fluid elastic layer formed based on kicker magnet and magnetic fluid produce force non-magnetizer not touch kicker magnet surface to the repulsive force of non-magnetizer and the phenomenon that occurs.For the structure relatively moved, the contact-making surface goodness of fit needing kicker magnet and non-magnetizer mutually to approach is larger and surface roughness is less, effectively could ensure uniform magnetic fluid elastic layer and exist.Then there is in the relative motion that guarantee is appealed the usefulness of minimal friction.
Kicker magnet is one or more permanent magnet or the combination with one or more electromagnet, be to wrap up completely or be not wrapped in other materials or by after combining with other object, its magnetic field intensity still can attracting magnetic fluid form the object of magnetic fluid elastic layer.Non-magnetizer refers to the solid body that can not be attracted by field of magnetic forece.
The mill difference coefficient of kicker magnet also between non-magnetizer of one side magnetic suspension structure, the hoverheight of suspended matter become inverse correlation with weight with the viscosity of magnetic fluid, become positive correlation with the extremely strong magnetic field magnetic field intensity of the magnetic saturation intensity of magnetic fluid.
Patent of the present invention provides completely newly a kind of and simple one side magnetic suspension structure.This structure can become invisible strong field of magnetic forece into a tangible magnetic fluid elastic layer by magnetic fluid and be bound in around kicker magnet surface, the non-magnetizer surface of magnetic fluid elastic layer to contact creates repulsive interaction, so this structure is provided with the usefulness suspending and lubricate, these two kinds of usefulness can be present in a structure individually or simultaneously.
