Embodiment
Below the present invention is described in detail.
Horse shoe shaped Permanent magnetic amtipodal gear wheel of the present invention comprises: the wheel base constitutes with horse shoe shaped permanent magnetism cumulative tooth two-part, wherein:
The wheel base section: take turns base and makes (for example aluminium, aluminum alloy or carbon fiber) by Nonferromugnetic material, having gap with taking turns basic wheel rim circumference equal intervals, the central authorities basic at wheel are provided with the rotating shaft mounting hole, to be connected with drive motor.
Horse shoe shaped permanent magnetism cumulative toothed portion: permanent magnetism cumulative tooth is made of U-shaped permanent magnet, strip and block permanent magnet two-part.The compound mode of these two kinds of permanent magnets is: the strip and block permanent magnet is embedded in the horse shoe shaped permanent magnetism opening.The height of strip and block permanent magnet is identical with the height of U-shaped permanent magnet.Permanent magnet is by hard magnetic material manufacturing (for example neodymium iron boron).
Horse shoe shaped permanent magnetism cumulative tooth is fixed in the wheel rim gap, and opening is to the wheel rim outside, and the horse shoe shaped permanent magnetism cumulative tooth on the wheel rim circumference is that the N utmost point and S are extremely equidistantly spaced.
Align installation with two horse shoe shaped Permanent magnetic amtipodal gear wheels are parallel, corresponding another S utmost point tooth of taking turns of one of them N utmost point tooth of taking turns leaves working gas gap between two gears.When a wheel turns, horse shoe shaped permanent magnetism cumulative tooth drives another gear and rotates by suction between the corresponding teeth and the repulsion transmitting torque between the adjacent teeth.
Below described content be the detailed description of in conjunction with the accompanying drawings the present invention being done, and should not be understood that it is limitation of the invention.
Please referring to Fig. 1, in the wheel rim circumference gap of wheel base 1, be inlaid with horse shoe shaped permanent magnetism cumulative tooth 2, this permanent magnetism cumulative tooth 2 is equidistant along the circumference gap, and N utmost point tooth and S utmost point tooth are spaced.Central authorities at wheel base 1 establish rotary shaft hole 3.The wheel base is by Nonferromugnetic material manufacturing (for example aluminium, aluminum alloy, carbon fiber).
Please referring to Fig. 2, horse shoe shaped permanent magnetism cumulative tooth 2 is made of U-shaped permanent magnet 2a and strip and block permanent magnet 2b, and its compound mode is: be inlaid with strip and block permanent magnet 2b in the opening of U-shaped permanent magnet 2a.The N utmost point of strip and block permanent magnet 2b and the S utmost point are respectively towards the N utmost point and the S utmost point of U-shaped permanent magnet 2a.Formed magnetic line of force 2c between the N utmost point of U-shaped permanent magnet 2a and the S utmost point.
Please referring to Fig. 3, when driving wheel 4 rotates, and relative displacement generation active force will take place between the follower 5, promptly produce suction between the horse shoe shaped permanent magnetism cumulative tooth 2 ' of the horse shoe shaped permanent magnetism cumulative tooth 2 of driving wheel 4 and corresponding follower 5; And the place ahead horse shoe shaped permanent magnetism cumulative tooth 2 " between produce repulsion, thus the moment of torsion of Chuan Diing make follower 5 and then driving wheel 4 rotate.
Please referring to Fig. 4, the rotatingshaft of drive motor 6 is installed in the rotary shaft hole 3 of driving wheel 4.The horse shoe shaped permanent magnetism cumulative tooth 2 of driving wheel 4 becomes the opposite pole corresponding relation with the horse shoe shaped permanent magnetism cumulative tooth 2 ' of follower 5, produces attraction force each other.Air gap is more little between the two-wheeled, and attraction force 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 rotation centrifugal distortion.
Advantage of the present invention is, reduced the volume 10% of gear, increases the active force 10% of permanent magnetism tooth, reduced manufacturing cost more than 10%.
