Description

A kind of Multilayer sleeve permanent magnetic vortex drive device that adopts 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 that adopts magnetism-gathering magnetic line structure.

Background technology

The basic functional principle of permanent-magnet eddy current drive technology is: when permanent magnet rotor and the motion for the relative rotation of ring of eddy rotor, the permanent magnet that in permanent magnet rotor, pole orientation is alternately arranged can produce alternating magnetic field in the ring of eddy of being made by electric conducting material, and then generate the eddy current of alternation within it, eddy current produces again Induced magnetic field in ring of eddy, stationary magnetic field in Induced magnetic field and permanent magnet rotor interacts, between two rotors, produce coupling torque, thereby reach the effect of transmitting motion and moment of torsion.The version of permanent magnetic vortex drive device mainly contains two kinds of socket type peace dish-types at present, and its application mainly comprises permanent magnet eddy current coupling (driver) and permanent-magnet eddy current speed regulator.Telescopic permanent magnetic vortex drive device wherein, has that structure is small and exquisite, weight is light, permanent magnetic material efficiency is high, eddy current loss is little, there is no the structures such as axial force and characteristic of property, in real work, has obtained 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, 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, in the situation that needs transmit larger torque and relatively high power, just must increase magnetic couple unit radially and/or axial dimension, increase diameter and/or axial width that conductor ring of eddy and permanent magnet group form annular solid, thereby cause the contour structure size of whole transmission device obviously to increase, and its inside exists very large clearance spaces, be 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, compare with ordinary single-stage speed regulator, can reduce the displacement in adjustment process, but the axial length of whole governor structure itself has increased more than one times, do not solve the problem that the telescopic permanent magnetic vortex drive device physical dimension of high-power/high-torque individual layer is large, inner space utilance is low.

and its place magnetic lining barrel dliameter to the acute angle forming all≤20 °, and angle is identical, the intersection point of the magnetizing direction of two blocks of magnet is arranged on the 4th corresponding with it ring of eddy one side, the magnetizing direction of outermost two blocks of magnet and its place magnetic lining barrel dliameter to the acute angle forming all≤50 °, and angle is identical, the intersection point of the magnetizing direction of two blocks of magnet is arranged on the 4th corresponding with it ring of eddy one side, described magnetic lining barrel dliameter is to being diametric(al) through the magnetic lining cylinder of corresponding magnetic blow out centre, the polar orientation that magnetizes of same group of the 4th permanent magnet group internal magnet is identical, the opposite polarity directions that magnetizes of two adjacent groups the 4th permanent magnet group, the 4th ring of eddy axial length is greater than the greatest axial length of the 4th corresponding permanent magnet layer.

8. the Multilayer sleeve permanent magnetic vortex drive device of employing magnetism-gathering magnetic line structure according to claim 7, it is characterized in that with being adjacent on the 4th p-m rotor body chassis corresponding to gap between the 4th permanent magnet layer, the 4th vortex rotor body chassis, being respectively arranged with several the 4th permanent magnetism coolant vents, the 4th eddy current coolant vent at described the 4th ring of eddy, on the 4th p-m rotor body chassis outer wall, be provided with the 4th permanent magnetism drainage hood, the 4th permanent magnetism drainage hood is corresponding one by one with the 4th permanent magnetism coolant vent; On the 4th vortex rotor body chassis outer wall, be provided with the 4th eddy current drainage hood, the 4th eddy current drainage hood is corresponding one by one with the 4th eddy current coolant vent.
