Description
Technical field
The utility model relates to a kind of magnetic drive, belongs to drive technology.
Background technology
Excellent characteristics such as the magnetic transmission has noncontact, no friction, friction, noiselessness, exempts to lubricate, non-maintaining, environmental protection and overload protection, thereby have a extensive future, the degree that is subject to people's attention increases day by day.Existing many magnetic drive technologies and magnetic drive are born, the practical and popularization that has.But the engaging force between the existing magnetic drive device, principal and subordinate wheel is little, can not transmit high-powerly, and the overwhelming majority is the concentric or parallel transmission of master and slave axial line, can realize that axial line intersects and the speed change transmission seldom.The magnetic drive that has intersects and the speed change transmission though can realize axial line, because its disk upper magnet is the discrete interval assembling, not compact, engaging force is big not enough, and the disk volume is big, cause whole magnetic drive volume to swell, the power that unit volume is transmitted is little.
Summary of the invention
The engaging force that the utility model mainly solves between the existing magnetic drive principal and subordinate wheel is little, can not transmit high-power problem, thereby improve whole magnetic drive specific volume power transmission value; Secondly, the utility model not only can be realized the transmission that two axial lines are concentric with parallel, and can realize that axial line intersects and the speed change transmission.
The utility model is realized by following technical scheme.
The interior circle of disk cylindrical is vertically fixed or radially the magnetized magnet spelling of alternating polarity become magnetosphere, the number of the magnet of magnetosphere is an even number, overlaps non magnetic high resistivity annulus outside magnetosphere admittedly, Zu He disk is called disk like this; The whole magnet ring of magnetosphere on the described disk also available along circumferential subregion and vertically or the magnetization of radial multi-pole alternating polarity form.If the mechanical strength that magnetosphere and described disk connect is enough, can remove the described magnetosphere non magnetic high resistivity annulus of solid cover outward from.At the fixing a plurality of same disks of a rotating shaft upper edge axially spaced-apart, the disk center is passed in rotating shaft, on the adjacent disk vertically or magnet heteropolarity radially relative, this and on disk form one group of transmission disk, organize as the active in the driver (or passive); Make another group transmission disk in the same way as passive or (active set) in the driver, what the size of this group disk and disk upper magnet number can be with last groups is identical or different.Principal and subordinate's disk groups is joined mutually the axially spaced-apart of two disks that insert the other side, but do not contact mutually and leave the gap, and the gap between principal and subordinate's disk equates, the degree of depth that participates in so that the geometric center lines of each magnet on two groups of disks at same straight line, the geometric center of each magnet on every group the disk is seen vertically on same circle, and is required principal and subordinate's disk upper magnet heteropolarity relative.Available described method is formed multistage many group disk drivers, realizes multistage transmission.Form the fixed magnetic conduction disk in outer face of disk of the axial outermost end of multistage many group disk drivers, reduce leakage field, improve the magnet utilance.
The geometric center place of the magnet on the disk and call reference circle with the concentric circle of rotating shaft, if this calibration diameter of a circle is D, if the magnet number on the disk is z, if each magnet shared arc length on reference circle is p, D=zp/ π=mz is then arranged, wherein m=p/ π is called modulus, and these settings and relational expression thereof are similar to mechanical gear.
Two groups of disks are pressed the preceding method engagement, and the computational methods of gearratio are also similar to the mechanical gear transmission.If revolution, the number of teeth of two disks that are meshed are respectively n
1, n
2, z
1, z
2, establishing gearratio is i
12, i then
12=n
1/ n
2=z
2/ z
1, thereby if z
1=z
2, just can realize the constant speed transmission, if z
1≠ z
2, just can realize the speed change transmission.Can form multistage many group disk drivers with described method, realize multistage transmission, the gearratio that its resultant gear ratio equals between each adjacent level is long-pending.
Transmission principle: with two groups of flat disk transmissions is the example explanation.Disk and from movable magnetic disc (hereinafter to be referred as principal and subordinate's disk) when meshing by described mode initiatively, the magnet heteropolarity of engagement place is close mutually, thereby the magnet of principal and subordinate's disk in the engagement place produces gravitation vertically.When principal and subordinate's disk generation micro angular displacement (in the engagement place, on principal and subordinate's disk vertically over against pair of magnets trackslip after, corresponding mutually area is not less than the angular displacement that was produced of a face area of single magnet at 50% o'clock), on the one hand this gravity direction intersects the off-axis direction with tangential direction that the active disk rotates, at this moment gravitation is decomposed into axial gravitation and tangential force gravitation, on the other hand, in the engagement place, on principal and subordinate's disk vertically over against pair of magnets trackslip after, this to magnet respectively with the opposite disk on another with original axially over against the adjacent magnet same polarity of magnet tiltedly right, thereby produce the crossing repulsion of tangential direction with initiatively disk rotation, this repulsion is decomposed into axial repulsion and tangential repulsion, aforesaid axial gravitation and axial repulsion opposite sign but equal magnitude described here and offset, and the tangential repulsion that acts on from the movable magnetic disc magnet end face is identical with aforesaid tangential force gravity direction, making a concerted effort of these two tangential forces, to make it follow initiatively disk rotation to produce driving torque from movable magnetic disc, after the magnet on described principal and subordinate's disk is to the disengaging engagement, next is to then entering engagement, constantly turned from movable magnetic disc moving, thereby realize that transmission is to reach the purpose of transmitted power.This principle is exactly the principle of various forms disk transmission in the utility model.
One group of disk of the present utility model can replace with the inductor that low-resistivity inductive material (as copper, aluminium and alloy thereof etc.) are made, when disk and inductor relatively rotate, know according to electromagnetic induction principle, if disk is a driving disc spacing pressing, inductor can be followed disk, if the inductor active rotation, disk can be followed the induction disk, thereby realizes transmission.The driver of this structure is at low temperature environment or the environment of cooling condition is arranged, and can realize at a high speed (disk and inductor be high speed rotating all, perhaps disk high speed rotating just, perhaps inductor high speed rotating just) transmission; The transmission that in principal and subordinate's disk, has side's disk must place hot environment, high temperature can make magnet forfeiture magnetic, available in the case inductor replaces it, with spacer inductor and disk are separated, thereby realization transmission, certain this situation should guarantee the thermal radiation of hot environment and can not damage the opposing party's disk in the spacer outside.
Magnet of the present utility model is a permanent magnet, electromagnet, superconducting magnet etc.
The utility model can be realized being similar to axis such as mechanical column gear transmission, internal gear transmission, Bevel Gear Drive, helical gear transmission, rack-and-pinion transmission and intersect or parallel speed change transmission.
Except advantage with existing magnetic drive technology, to compare with existing magnetic drive technology, the utility model also has following advantage:
1, existing magnetic drive, principal and subordinate's disk is its magnet or only by tangential magnetic attraction in the engagement place, only produce engaging force by tangential magnetic repulsion, so engaging force is little, and the utility model since the magnet of two disk engagement places produce along the tangential suction and repulsion of disk, the direction unanimity of suction and repulsion so engaging force is very big, can be transmitted bigger power;
2, magnet is arranged compactly, and dwindled the disk volume, thereby whole driver volume is reduced, so, big many of the existing magnetic drive device of power ratio that the whole transmission device unit volume is transmitted;
3, can realize that axial line intersects arbitrarily and the speed change transmission;
4, because the adjacent magnetosphere that is combined into of disk upper magnet alternating polarity, perhaps with a whole magnet ring along circumferential subregion and vertically or the magnetization of radially multipole alternating polarity form magnetosphere, and the fixed magnetic conductor in the outside of the magnetosphere of the outermost end of driver, so driver is than little many of existing magnetic drive leakage field, thereby the magnet utilance is very high;
5, because the magnet of two disk engagement places produces suction and repulsion equal and opposite in direction and direction counteracting on the contrary mutually vertically, so do not have axial force between principal and subordinate's disk;
6, (disk and inductor be high speed rotating all must to place the high speed of hot environment for one group of disk, it perhaps is the disk high speed rotating, perhaps be the inductor high speed rotating) the transmission situation, the utility model realizes that drive method is to place one group of disk of hot environment to replace with the low-resistivity inductor, and disk can by solar heat protection or the eddy current thermal radiation infringement that can sensed body produce because of electromagnetic induction or disk be in low temperature environment or disk is in the environment that cooling condition is arranged.Must place the high speed transmission situation of hot environment for one group of disk, existing magnetic drive is difficult to accomplish, even can't accomplishes.
