Hereinafter, a preferred embodiment of the present invention with reference to the drawings in detail.

1 is a view for explaining the principle of the horizontal power transmission of the power transmission device by the magnetic force according to an embodiment of the present invention, Figure 1a is a front view showing that the outer peripheral surface of the driving magnet and the driven magnet is rotated, Figure 1b 1C is a plan view thereof, and FIG. 1C is a plan view showing that outer circumferential surfaces of a plurality of driven magnets different in size from the driving magnet are absorbed and rotated, respectively.

1A and 1B, the circumferential surface of the driven rotating body 20 made of a double-sided two-pole cylindrical magnet is formed on the circumferential surface of the drive-rotating body 10, which is preferably axially coupled to the driving motor. Coupled by mutual attraction force.

When the driving rotary body 10 rotates, the driven rotary body 20 is rotated in the opposite direction to each other. This is because the magnetic attraction force between the magnets acts as a kind of vertical drag at the point of contact with each other, and the relative rotation occurs by the principle of action reaction by friction acting in proportion to the vertical drag. At this time, the magnetic force is balanced between the driving rotary body 10 and the driven rotary body 20 along the magnetic force line, which causes the relative rotation to occur easily without a rotational resistance despite the strong suction force. . In addition, the driving rotary body 10 and the driven rotary body 20 is formed in a cylindrical shape having a smooth outer surface, the frictional resistance is minimized when the mutual rotation occurs. As a result, the driving rotary body 10 is rotated by the minimum rotational resistance and frictional resistance, and the driven rotary body 20 adsorbed thereto also causes relative rotation to occur at the same rotational speed so that the minimum rotational force is eliminated without a separate connecting member. Rotational power is transmitted by force, and through this, various types of rotating devices and rotating materials can be configured.

In FIG. 1C, the power transmission structure will be expanded into a structure in which a plurality of driven rotary bodies are continuously adsorbed and coupled. Referring to FIG. 1C, a driving rotary body 10 made of a double-sided two-pole cylindrical magnet axially coupled to the driving motor M is disposed at the center thereof, and a driven rotary body 20 made of a plurality of double-sided two-pole cylindrical magnets is attracted. Are placed by coupling. The driven rotating body 20 may be used as the magnet size may be changed as shown, and may be used by selectively replacing the ferromagnetic material. At this time, when the size of the magnet is changed, a difference in each rotational speed occurs. On the other hand, when the ferromagnetic material is used, only the ferromagnetic material should not be combined, but the magnet and the ferromagnetic material must be coupled together.

As shown, when the plurality of driven rotors 20 are closely and continuously adsorbed on one drive rotor 10, the adsorption support force of each other appears to be strong, and the driving force of one drive rotor 10 is rotated. It is possible to rotate the plurality of driven rotating body 20 by the force it is possible to transmit power to the multi-axis without a separate connecting member. This is a technical principle that can configure a power transmission device capable of driving a multi-axis while maintaining a strong supporting force without a separate connecting member by minimizing the separate rotational resistance and frictional resistance.

Figure 2 is a view for explaining the vertical power transmission principle of the power transmission device by the magnetic force according to an embodiment of the present invention, Figure 2a is a front view showing that the outer peripheral surfaces of the drive and the driven rotor is vertically adsorbed and rotated, respectively. 2B is a plan view thereof.

As shown, when the driving rotary body 10 and the driven rotary body 20 are combined in a cross shape, and the upper driving rotary body 10 is rotated, the driven rotary body 20 is rotated relative to the direction of the arrow. This is because the driven rotating body 20 is biased to one side of the driving rotating body 10, a strong magnetic attraction force acts on a portion of the driven rotating body 20 close to the driving rotating body 10, and is far from the driving rotating body 10. This is because a relatively weak magnetic attraction force is applied to a portion of the driven rotating body 20 on the side. In other words, the magnetic attraction force corresponds to the vertical drag, and the friction force is proportional to the vertical drag, so that the frictional force acts on a part of the driven rotor 20 close to the driving rotor 10 so that the driven rotor 20 is a kind of force. Rotation torque is generated to rotate relative to the rotation of the drive rotary body (10).

3 is a view for explaining the principle of power transmission between magnets coupled to the gear of the power transmission device by the magnetic force according to an embodiment of the present invention, Figure 3a is a drive rotating body and the driven rotating body coupled to the gear adsorption / coupling 3B is a plan view thereof, and FIG. 3C is a plan view showing that the driving rotor coupled to the gear and the gears are coupled to each other to rotate by attracting / combining a plurality of driven rotors of different sizes. .

Referring to FIG. 3, the gears 13 and 23 may be coupled to the driving rotating body 10 or the driven rotating body 20. In this case, the driving rotary body 10 and the driven rotary body 20 is a pair of adsorption means (11, 12, 21, 22) made of a double-sided two-pole cylindrical magnet as shown between the gears (13, 23) It is preferable that the form is coupled to, and the gear train may be integrally formed on the circumferential surface of a single magnet.

At this time, it is preferable that the release prevention plate (11a, 12a) for preventing the separation when the mutual coupling between the driving rotary body 10 or the driven rotary body 20 is formed.

Such a gear coupling structure can be relatively rotated along the center gear train while the driving rotary body 10 and the driven rotary body 20 are coupled by mutual suction force, and are relatively rotated by the aforementioned point contact friction. Compared to the magnet coupling, the precision can be increased. In addition, it is possible to have a strong coupling force without a separate shaft support structure, compared to the structure in which only gears are combined, and it is very useful for constructing a simple mechanism because there is no need for a mutual connection member.

On the other hand, the double-sided two-pole cylindrical magnets used in the drive rotating body 10 and the driven rotating body 20 are preferably permanent magnets, and more preferably neodymium magnets mainly composed of neodymium, iron oxide and boron. In addition, the outer surface of the magnet is preferably coated with urethane, Teflon resin, etc. to prevent corrosion and breakage of the magnet, it is preferable that the gears coupled between the magnets are subjected to a thermal surface treatment to minimize the wear rate during rotation. Do.

The rotating decoration may be a flower-like or animal-like general decoration, or a functional decoration such as a fan blade. In the case of the direct coupling, the rotating ornament 21 merely performs the rotational movement, but in the case of the coupling through the crankshaft 23, it may serve as a reciprocating movement. In the figure, the simple rotational plant represents the 'station' and rotates, and the rotating plant coupled through the crankshaft reciprocates by the reciprocating motion of the crankshaft. To this end, the rotating ornament coupled to the crankshaft is coupled to idle on the rotational axis of the other driven body.

It is also possible to provide a small generator 22 having a light emitting diode 22a on the rotating shaft. In this case, since the rotational power transmitted by the driving motor M is converted into electrical energy again through the small generator 22 to light up the light emitting diode 22a. It can be usefully used if it is provided with an isolation member.

The plurality of driven rotating bodies 20 are closely disposed on the driving rotating body 10 so as to be adsorbed closely together, so that the supporting force of each other appears strongly, and by the supporting force, the driving rotating body 10 and the driven rotating body 20 are provided.
