Fig. 2 is the vertical view of Fig. 1.
Embodiment
Fig. 1 is electromagnetic levitation type DC generator structural representation provided by the invention, Fig. 2 is the vertical view of Fig. 1, as depicted in figs. 1 and 2, this electromagnetic levitation type DC generator comprises base 1, outer magnetic ring 2, internal magnetic ring 3, winding coil 4, coil brace 5, wheel shaft bracing or strutting arrangement 6, rotating shaft 7, the first sprocket transmission device 8, the second sprocket transmission device 9, and rotating link chain 10.Particularly, on the upper surface of base 1, miscellaneous part is set, wherein, the structure of outer magnetic ring 2 and internal magnetic ring 3 is the cylinder of hollow, and the magnetic pole of outer magnetic ring 2 and internal magnetic ring 3 is distributed in respectively on cylindrical outer surface and inner surface.Take outer magnetic ring 2 as example, and the cylinder of outer magnetic ring 2 has outer surface and inner surface, and on the outer surface, another magnetic pole correspondingly sets within it on surface in a magnetic pole setting of outer magnetic ring 2.The pole orientation of internal magnetic ring 3 distributes identical with outer magnetic ring 2, and even outer magnetic ring 2 outer surfaces are the N utmost point, and inner surface is the S utmost point, and the outer surface of internal magnetic ring 3 is the N utmost point too, and inner surface is similarly the S utmost point.Outer magnetic ring 2 and internal magnetic ring 3 are the cylinder of hollow, therefore all have separately inside radius and outer radius, and described inside radius is cylindrical central point to the distance of inner surface, and described outer radius is cylindrical central point to the distance of outer surface.Because the present invention will be arranged on internal magnetic ring 3 in outer magnetic ring 2, therefore not only to keep internal magnetic ring 3 identical with the pole orientation of outer magnetic ring 2, certainly outer radius that also will regulation internal magnetic ring 3 is less than the inside radius of outer magnetic ring 2, like this under the magnetic field interaction force between internal magnetic ring 3 and outer magnetic ring 2, internal magnetic ring 3 can suspend and be arranged in the cavity of outer magnetic ring 2, and the two does not contact mutually.
In order to keep the stable of outer magnetic ring 2, the present invention is fixedly installed on outer magnetic ring 2 on base 1, and the central shaft of outer magnetic ring 2 is parallel with base 1.Specifically the outer surface of outer magnetic ring 2 can be fixed on to base 1 by modes such as stickups.Internal magnetic ring 3 to identical, is that the central shaft of internal magnetic ring 3 is parallel with base 1 with the setting party of outer magnetic ring 2 equally.Internal magnetic ring 3 is owing to being to be suspended in outer magnetic ring 2 in the present invention, therefore internal magnetic ring 3 can be around its axis rotation, so the rotor of the present invention using internal magnetic ring 3 as DC generator, and because internal magnetic ring 3 does not contact with other parts, greatly reduce frictional force, reduced component wear, thereby improved the generating efficiency of DC generator, and can increase the service life, reduced maintenance cost.
Can be using winding coil 4 as stator in the present invention, particularly, inner surface at internal magnetic ring 3 forms the first space as shown in Figure 1, between outer magnetic ring 2 and internal magnetic ring 3, form second space, in the present invention, wire can be by being arranged in the first space and second space to form winding coil 4 repeatedly, in winding coil 4 is around in internal magnetic ring 3, but do not contact with internal magnetic ring 3, certainly do not contact with outer magnetic ring 2 yet.The two ends that the two ends of winding coil 4 lay respectively at outer magnetic ring 2 and internal magnetic ring 3 are aperture position, for the fixing locus of winding coil 4 between outer magnetic ring 2 and internal magnetic ring 3, the present invention is also respectively arranged with a coil brace 5 at the two ends of outer magnetic ring 2 and internal magnetic ring 3, and the two ends of winding coil 4 are just fixedly installed on respectively on corresponding coil brace 5.Coil brace 5 is fixedly installed on base 1 too.
In the present invention, on base 1, the side that is positioned at outer magnetic ring 2 is also provided with a wheel shaft bracing or strutting arrangement 6.On wheel shaft bracing or strutting arrangement 6, be provided with a rotating shaft 7, this rotating shaft 7 can be connected for the output shaft of equipment that DC generator of the present invention is provided for the power resources of generating with turbine etc., and rotates with the rotation of output shaft.In rotating shaft 7, be also fixedly installed on two the first sprocket transmission device 8, the first sprocket transmission devices 8 and be provided with rotating link chain 10.
In order to allow the internal magnetic ring 3 as rotor rotate, the present invention has also been fixedly installed respectively second sprocket transmission device 9 at the two ends of internal magnetic ring 3, and the second sprocket transmission device 9 and the first sprocket transmission device 8 are oppositely arranged.Rotating link chain 10 one end are connected on the first sprocket transmission device 8, the other end is connected on the second sprocket transmission device 9, like this when rotating shaft 7 is rotated, the first sprocket transmission device 8 can rotate with rotating shaft 7, the first sprocket transmission device 8 just can drive rotating link chain 10 to rotate, rotating link chain 10 drives the second sprocket transmission device 9, the second sprocket transmission devices 9 just to drive internal magnetic ring 3 together to rotate thereupon.
In the above-described embodiments, preferably the size of two the second sprocket transmission devices 9 is identical, can guarantee preferably the stress balance of internal magnetic ring 3 both sides like this, guarantee that internal magnetic ring 3 can not leave the control in outer magnetic ring 2 magnetic fields when speed change is rotated or rotated with arbitrary speed, has solved to the problem of internal magnetic ring 3 transmissions.Certainly, what those skilled in the art can be known is, if the size of two the second sprocket transmission devices 9 is not identical, the first sprocket transmission device 8 that corresponding size also can solution be by other means for example set is also fine, as long as guarantee the stressed identical of internal magnetic ring 3 two ends, rotating speed unanimously.
