Embodiment
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, is provided with an annular groove 2 at the wheel rim place of wheel base 1, and the notch of this annular groove 2 is outside.At annular groove 2 internal fixation (as with bolt etc.) block permanent magnet 3, this permanent magnet 3 being arranged is that heteropole is equidistantly arranged at interval.The length of permanent magnet 3 and between optimal spacing want factors such as comprehensive driving torque, vibration frequency, interlock precision to design, those design factors are essential factors of considering when designing and producing gear, thereby be the ordinary skill that those skilled in the art are familiar with, this is not described in detail.Permanent magnet 3 forms the dark tooth of permanent magnetic field on wheel rim, be also referred to as the permanent magnetism tooth.Its permanent magnet 3 surfaces and wheel rim smooth transition.Permanent magnet 3 is made (as: Nd-Fe-Bo permanent magnet material) by hard magnetic material, and wheel base 1 is made (as: carbon steel, silicon steel, stainless steel, cobalt, nickel or its alloy etc.) by ferromagnetic substance.
In conjunction with Fig. 2, the permanent magnetism toothing on the wheel base 1 has been described.Annular groove 2 internal fixation at wheel base 1 have permanent magnet 3, are provided with nonferromagnetic tesserae 2b between this permanent magnet 3 and the annular groove wall 2a and between per two permanent magnets 3, the magnetic flux profile 3a that forms between permanent magnet 3 and the annular groove wall 2a.The optimal spacing of permanent magnet 3 and annular groove wall 2a is about the 40-80% of permanent magnet 3 circumference arc length.
See also Fig. 3, align installation with two annular groove ermanent magnetic teeths of the present invention are parallel, permanent magnet 3 on two annular groove ermanent magnetic teeths is that heteropole is relative, i.e. the N utmost point of the permanent magnetism tooth on extremely corresponding another annular groove ermanent magnetic teeth of the S of the permanent magnetism tooth on one of them annular groove ermanent magnetic teeth.As can be seen from the figure, when one of them annular groove ermanent magnetic teeth is driving wheel, when this driving wheel 4 rotates under the driving of motor 5 (direction as shown by arrows), to be subjected to displacement with the annular groove ermanent magnetic teeth (being called follower 6) of another parallel installation, to produce suction between the permanent magnetism tooth 3 of the permanent magnetism tooth 3 of driving wheel 4 and follower 6 thus, and will produce repulsion between the follower permanent magnetism tooth adjacent with its place ahead, therefore transmitted moment of torsion, its sense of rotation as shown by arrows.
Again in conjunction with Fig. 4, on the driving wheel 4 between the permanent magnetism tooth 3 of permanent magnetism tooth 3 and corresponding follower 6 heteropole corresponding, because of air gap is more little, gravitation is big more.So as far as possible little when design two-wheeled spacing, its design principle is that two-wheeled must not come in contact collision when temperature expansion and the centrifugal deformation of rotation.
Because two permanent magnetism teeth of the present invention are that heteropole is corresponding, during one of them wheel turns, will drive another wheel turns, formed the non-contact transmission of moment of torsion, thus environmental protection when transmitting torque, energy-conservation, do not have that wheel odontotripsis, noiseless, mechanical vibration are little, long service life, mechanics good buffer effect and cost be low.
