Specific embodiment: following further describes the present invention with reference to the drawings:
Double magnet-wheels without the non-contact forward drive device of backlass permanent magnetism, the device include servo motor 5, gear unit 4,
Driving wheel 2 and irony guide rail 1；Driving wheel is connected as one by gear unit and servo motor, and drive wheel circumferences surface is uniform
Permanent magnets 3 are inlaid with, irony guide rail 1 is arranged above driving wheel 2 and does not contact with driving wheel 2, makes the two in the feelings not being attracted
Under condition, maximum driving force is generated.Irony guide rail 1 is that double wedge radial section is in arc-shaped and the irony rack gear without permanent magnet
Component；At a deflection angle α, which is the tooth positions of the permanent magnets 3 of the top and irony guide rail 1 when driving wheel 2 is static
It is formed in this way, a vertical line is drawn to driving wheel in the center of the double wedge of the irony guide rail 1 nearest from the permanent magnets 3 from the top
Planar shaped commercial base one, then draws an oblique line into the permanent magnets 3 of 2 the top of driving wheel from the intersection point one where 2 axis
The heart, the angle between this oblique line and vertical line are exactly deflection angle α, this angle makes guide rail keep balancing in horizontal position,
Eliminate the backlass between driving wheel 2 and the iron guide rail 1 of arc-shaped double wedge, and the position by changing servo motor 5 or
Adjust the angle [alpha] between 2 double wedge of driving wheel and 1 double wedge of iron guide rail or change driving wheel 2 and guide rail 1 relative position L1 and
L2 can arbitrarily adjust driving force threshold in a certain range.(due to magnet-wheel to the attraction size of irony guide rail with magnet-wheel with
The variation of air gap between irony guide rail and change.) so-called change relative position L1 and L2 be exactly L1 and L2 institute shown in mobile Fig. 1
The distance shown.
Guide rail double wedge be it is arc-shaped, the groove groove width formed between double wedge is identical with the double wedge facewidth, and guide rail width and
The driving wheel of underface is wide (can also to be thickness, be exactly the direction in driving wheel axial width and Fig. 1 perpendicular to paper
Thickness)；If guide rail width is bigger than driving wheel width, required driving force can be smaller than wide, if guide rail width ratio
Driving wheel is small, required driving force with it is wide identical, so wide, driving wheel is two, the top when driving wheel is static
Permanent magnets and respectively corresponding irony guide rail (1) double wedge at certain deflection angle α, but the deflection angle of two driving wheels
Contrary, the permanent magnet on two driving wheels (2) is cylindrical-shaped structure, which, which is embedded in driving wheel (2) circumference, makes,
Driving wheel (2) outer forms double wedge and groove structure, cylindrical-shaped structure are identical to the attraction of iron guide rail (1) double wedge, due to
Two driving wheels are identical as double wedge angulation similar in corresponding irony guide rail, so the suction of two magnet-wheel double wedges and corresponding double wedge
Gravitation is equal in magnitude, contrary, can make its stress balance in the horizontal direction.
Driving wheel material is non-magnetic aluminum alloy, in the uniform alternate arrangement groove of driving wheel external peripheral surface, in slot
Inlay cylindrical magnet iron.
The space width of matter guide rail 1 is equal with drive wheel groove spacing.
The double wedge of permanent magnets 3 on driving wheel 2 and irony guide rail 1 has a certain degree α.Purpose can eliminate elimination driving
Backlass between wheel 2 and the iron guide rail 1 of arc-shaped double wedge, and the position L1 and L2 by changing servo motor 5 or drive
The angle [alpha] of the double wedge of permanent magnets 3 and irony guide rail 1 on driving wheel 2, can arbitrarily adjust driving force threshold in a certain range.
In driving force suffered by 3 irony guide rail of comparison diagram, 1 horizontal direction and Fig. 4 suffered by 1 horizontal direction of irony guide rail
The provable double magnet-wheels of driving force without the non-contact forward drive device of backlass permanent magnetism can to eliminate driving wheel 2 convex with arc-shaped
Backlass between the iron guide rail 1 of tooth.Horizontal force in Fig. 3 is that 0 proof has backlass, and Fig. 4 horizontal force is not zero
Then without backlass.
Cylindrical magnet iron is the permanent magnet of NdFeB material, which half-and-half magnetizes in diametrical direction,
Half is the pole N, and half is the pole S, as shown, the pole orientation of all permanent magnets is identical.
Have certain interval between double magnet-wheels and guide rail, and the direction of rotation of double magnet-wheels is identical, it can be ensured that magnet-wheel with lead
Rail is without backlass.
Driving wheel in the present invention is direct-connected through transmission shaft and servo motor 5 or is connect by shaft coupling and bearing block, this side
Formula is for the occasion that driving force is larger or rigidity requirement is high.
There are certain gaps in vertical direction for driving wheel and guide rail, pass through the offer that attracts each other of magnet and guide rail double wedge
Tractive force.Since driving wheel is contactless with guide rail, therefore the device has longer service life.
Permanent magnetism noncontact driving device of the invention can be used for the dustless conveyer system of permanent magnet suspension.In figure, guide rail 1 is magnetic conduction
Material is fixed above operating path, can carry out track laying by actual demand.The double wedge circular arc of guide rail, groove
Groove width is identical as the double wedge facewidth, and guide rail width and the driving wheel of underface are wide.Driving wheel is by non magnetic aluminum alloy materials system
It makes, drives transmission shaft to be rotated by servo motor, be equidistantly inlaid with permanent magnet, its spacing in the external peripheral surface of driving wheel
It is identical as the overlying guide rail facewidth, and permanent magnet is corresponding with guide rail double wedge.There are certain gap between driving wheel and guide rail, two are avoided
The contact of person.When servo motor drives driving wheel rotation, driving is realized by the attraction between permanent magnet group and guide rail.Due to
Guide rail is fixed, and system where driving device will will drive moves in a straight line, can by control servo motor rotation speed and steering
The movement velocity of further control system and direction.Of course, it can be reversed executes, even if driving device is fixed, guide rail is moved
It is dynamic.
The present invention is based on linear motor principles, easy to maintain, and structure is simple, environmental protection and energy saving, low cost.
