Description

A kind of Multilayer sleeve permanent magnetic vortex drive device adopting magnetism-gathering magnetic line structure

Technical field

The invention belongs to permanent-magnet eddy current drive technology field, particularly relate to a kind of Multilayer sleeve permanent magnetic vortex drive device adopting magnetism-gathering magnetic line structure.

Background technology

The basic functional principle of permanent-magnet eddy current drive technology is: when permanent magnet rotor and ring of eddy rotor is for the relative rotation move time, the permanent magnet that in permanent magnet rotor, pole orientation is alternately arranged can produce alternating magnetic field in the ring of eddy be made up of electric conducting material, and then generate the eddy current of alternation within it, eddy current produces Induced magnetic field again in ring of eddy, stationary magnetic field in Induced magnetic field and permanent magnet rotor interacts, between two rotors, produce coupling torque, thus reach the effect of transmitting motion and moment of torsion.The version of permanent magnetic vortex drive device mainly contains socket type peace dish-type two kinds at present, and its application mainly comprises permanent magnet eddy current coupling (driver) and permanent-magnet eddy current speed regulator.Wherein telescopic permanent magnetic vortex drive device, has compact structure, weight is light, permanent magnetic material efficiency is high, eddy current loss is little, do not have the Structure and Properties features such as axial force, in real work, obtain successful Application widely.

Existing coaxial sleeve cartridge type permanent magnetic vortex drive device, no matter be shaft coupling or speed regulator, employing be all individual layer telescoping structure, namely in each telescopic permanent magnetic vortex drive device, only have one group of permanent magnet and a conductor ring of eddy, the two forms one group of magnetic couple unit jointly.The telescopic permanent magnetic vortex drive device of this individual layer, when needs transmit larger torque and relatively high power, just must increase radial direction and/or the axial dimension of magnetic couple unit, namely diameter and/or the axial width of conductor ring of eddy and permanent magnet group formation annular solid is increased, thus cause the contour structure size of whole transmission device obviously to increase, and its inside also exists very large clearance spaces is not fully used.Application number is the Chinese patent " a kind of secondary series type permanent-magnet speed governor " of CN201010192485.0, two groups of individual layer coaxial sleeve cartridge type permanent-magnet eddy current coupling units are cascaded vertically, utilize same speed regulating device to drive speed governing, compared with ordinary single-stage speed regulator, the displacement in adjustment process can be reduced, but the axial length of whole governor structure itself increases more than one times, do not solve the problem that high-power/high-torque individual layer telescopic permanent magnetic vortex drive device physical dimension is large, inner space utilance is low.

Existing coaxial sleeve cartridge type permanent magnetic vortex drive device generally adopts individual layer telescoping structure, and its main cause is the consideration for needing ring of eddy heat radiation, and its essence root is then the problem of magnetic Circuit Design.So far, the magnetic Circuit Design of telescopic permanent-magnet eddy current driver (comprising speed regulator and shaft coupling) mostly adopts discrete magnetic structure, namely on the inner surface or outer surface of magnet rotor cylinder, circumferentially be evenly arranged even numbered blocks permanent magnet, each block of magnet radially magnetizes, adjacent two pieces of magnet magnetic direction are contrary, and distance relatively far apart.The permanent-magnet eddy current coupling unit of this magnetic structure, can produce larger vortex flow of inducting during work in ring of eddy, thus generates more eddy current heat, must be shed in time, in case workpiece temperature is too high.Individual layer telescoping structure, especially ring of eddy are arranged in the single-layer type structure in outside, are conducive to heat radiation, are therefore widely adopted.

In recent years, the cost along with high performance permanent magnetic materials reduces and popularization and application, and the modern times magnetize the development of technology, and Optimize magnetic circult design theory is also developed rapidly to be improved and be actually applied, and novel magnetic structure emerges in multitude.Modern magnetic Circuit Design theory and means is applied to promoting of permanent magnetic vortex drive device, can develop that transmission efficiency is higher, eddy current loss and heating is less, the permanent magnetic vortex drive device of structural configuration more compact, to promote the level of permanent-magnet eddy current drive technology.
