Embodiment
The horse shoe shaped permanent magnetic gear wheel that the present invention proposes is made of nonferromagnetic wheel base and horse shoe shaped permanent magnetism tooth two-part, wherein:
The wheel base section is made the wheel base by Nonferromugnetic material (as non-magnetic materials such as polyamine fat, teflon, aluminum alloy or copper).Wheel rim at the wheel base has gap equally spacedly along circumference, is used for fixing horse shoe shaped permanent magnetism tooth described later.Central authorities at the wheel base are provided with the rotatingshaft mounting hole.
Horse shoe shaped permanent magnetism toothed portion is made U-shaped permanent magnet by hard magnetic material (as Nd-Fe-Bo permanent magnet material), and an end is the N utmost point, and the other end is the S utmost point, forms horse shoe shaped permanent magnetism toothing, and the recess between the N utmost point and the S utmost point is provided with the nonferromagnetic tesserae.
Horse shoe shaped permanent magnetism tooth heteropole is adjacent to inlay the gap bottom that is fixed on the wheel rim circumference, forms the horse shoe shaped permanent magnetic gear wheel.The N utmost point of horse shoe shaped permanent magnetism tooth and the spacing optimum value of the S utmost point are the 50-80% of horse shoe shaped permanent magnetism tooth circumference arc length.
When specific design, the spacing of two adjacent horse shoe shaped permanent magnetism teeth will be taken all factors into consideration driving torque, vibration frequency, factors such as interlock precision.Because those design factors known factor when being design of gears, and the emphasis that neither the present invention will discuss, therefore be not described in detail.
Align installation with above-mentioned two horse shoe shaped permanent magnetic gear wheels are parallel, promptly form drivetrain of the present invention.Horse shoe shaped permanent magnetism tooth during installation on two horse shoe shaped permanent magnetic gear wheels is that heteropole is corresponding.When rotating under one of them horse shoe shaped permanent magnetic gear wheel driving,, drive another gear and rotate by the repulsion transmitting torque between the suction between the corresponding tooth and the place ahead adjacent teeth at motor.Air gap between two horse shoe shaped permanent magnetic gear wheels is as far as possible little, and its design principle is a temperature expansion and when rotating centrifugal deformation, does not contact between two horse shoe shaped permanent magnetic gear wheels.
The following stated content is the detailed description of in conjunction with the accompanying drawings the present invention being done, and should not be understood that limitation of the invention.
Seeing also Fig. 1, is general structure schematic representation of the present invention.As can be seen from the figure, be inlaid with U-shaped permanent magnet tooth 2 in the wheel rim circumference gap of wheel base 1, this horse shoe shaped permanent magnetism tooth is dark tooth, its surface and wheel rim smooth transition, but magnetic intensity highlights on the nonferromagnetic wheel rim herein, forms permanent magnetism " magnetic field tooth " 2c.Center at wheel base 1 is provided with axle hole 3.Wheel base 1 is made by Nonferromugnetic material.Horse shoe shaped permanent magnetism tooth 2 is made by hard magnetic material.
The structure of horse shoe shaped permanent magnetism tooth 2 is described in conjunction with Fig. 2.Horse shoe shaped permanent magnetism tooth is inlayed the bottom surface that is fixed on the wheel rim gap, and wherein an end 2a is the S utmost point, and the other end 2b is the N utmost point.The extreme 2b of extreme 2a of S and N surface and wheel rim smooth transition are provided with nonferromagnetic tesserae 5 between the two ends, the optimal spacing at two ends is about the 50-80% of these tooth 2 circumference arc length.The magnetic flux profile 2c that forms between extreme 2a of S and the extreme 2b of N.U-shaped permanent magnet is spaced in wheel rim equal intervals and heteropole.The wheel rim length of permanent magnetism tooth and spacing can not be simply definite, take all factors into consideration driving torque, vibration frequency, interlock precision or the like.
Seeing also Fig. 3, is that horse shoe shaped permanent magnetism tooth magnetic gear rotation dynamic torque of the present invention transmits schematic representation.As can be seen from the figure, when driving wheel 6 rotates under the driving of motor 7, will and follower 8 between be subjected to displacement.Produce suction between the horse shoe shaped permanent magnetism tooth 2 ' of the horse shoe shaped permanent magnetism tooth 2 of driving wheel 6 and corresponding follower 8 thus, produce repulsion between the follower permanent magnetism tooth adjacent, therefore transmitted moment of torsion with the place ahead.
In conjunction with Fig. 4 two corresponding relations between the horse shoe shaped permanent magnetic gear wheel are described.Motor 7 is installed in the axle hole 3 of driving wheel 6, the horse shoe shaped permanent magnetism tooth S utmost point 2 ' a and the N utmost point 2 ' b that the horse shoe shaped permanent magnetism tooth S utmost point 2a of driving wheel 6 and N utmost point 2b correspond to follower 8, this heteropole corresponding relation, air gap is more little, suction is big more, so both gaps are as far as possible little, its design principle is that both must not come in contact collision when temperature expansion and the centrifugal deformation of rotation.
The present invention has following advantage:
1, there are not wearing and tearing, long service life, safe and reliable between the gear.
