Description

  The present invention relates to a power generator, and more particularly to a power generator that generates power using the rotational force of a disk.

  Generally, a generator is configured to generate an induced electromotive force in an armature (stator) that has undergone a magnetic flux change by rotation of a rotor having magnetic poles, and the armature is fixed. Therefore, the relative speed between the rotor and the armature cannot be increased so much, and it is difficult to efficiently generate the induced electromotive force. In addition, it is conceivable to increase the rotational speed of the rotor by providing a transmission gear or the like. However, not only may a large centrifugal force be applied to the parts constituting the rotor, causing damage to the parts. In addition, there is a possibility that the entire generator may be broken due to the natural vibration based on the high-speed rotation.

  Therefore, for example, in Japanese Patent Application Laid-Open No. 2003-235223, a first rotation mechanism that rotates a magnet in response to driving from an external rotating body such as a bicycle tire and a second rotation mechanism that rotates a core member or a coil. Has been proposed, and these magnets and coils are respectively rotated in opposite directions. According to this generator, by providing a mechanism for rotating the magnet and the coil in opposite directions, the relative speed between the coil and the magnet is increased, and a larger induced electromotive force can be generated. Further, since it is not necessary to rotate only one side of the magnet or coil at high speed, it is possible to reduce the failure of the generator based on centrifugal force, natural vibration, or the like.

JP 2003-235223 A

  However, in the conventional generator, there is a problem that stable power supply cannot be performed because the first rotating mechanism and the second rotating mechanism are rotated by receiving driving from an external rotating body such as a bicycle tire.

  Also, since the relative speeds of the first rotating mechanism and the second rotating mechanism are controlled by a single external rotating body, the setting of the relative speed is limited compared to the case where the speed of each rotating mechanism is controlled. There is a problem that it is difficult to freely adjust the power to be generated.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a generator that can stably supply power and can freely adjust the generated power.

Drive means and second drive means for rotating the fourth disk, wherein the first drive means and the second drive means rotate the rotor and armature in opposite directions. Thus, the third disk and the fourth disk are respectively rotated in opposite directions.

  A first support column rotatably attached to the rotor, armature, first disc and second disc; a second support post rotatably attached to the third disc; and the fourth disc And a third support column rotatably attached thereto.

  The outer peripheral surface of the fourth disk 11 is in surface contact with the outer peripheral surface of the second disk 5, and the rotational force of the fourth disk 11 is transmitted to the second disk 5.

  Further, in order to efficiently rotate the rotor 2 and the armature 3 at high speed, the diameter of the third disk 8 is longer than the diameter of the first disk 4, and the diameter of the fourth disk 11 is the second value. It is preferable that the diameter of the disk 5 is longer.

  Two first disks 4 are connected to the upper and lower parts of the rotor 2, and two second disks 5 are connected to the upper and lower parts of the armature 3. Correspondingly, two third disks 8 and four fourth disks 11 are provided above and below, respectively.

  However, the number of the first to fourth disks 4, 5, 8, 11, the first drive motor 7, and the second drive motor 10 is not limited to the above, and may be only one or three or more. Also good.

  The rotating part 7a of the first drive motor 7 is in contact with the lower surface of the third disk 8, and the third disk 8 is rotated by the rotation of the rotating part 7a.

  The rotating part 10a of the second drive motor 10 is in contact with the lower surface of the fourth disk 11, and the fourth disk 11 is rotated by the rotation of the rotating part 10a.

  As a drive source of the first drive motor 7 and the second drive motor 10, for example, a battery, a fuel cell, a solar cell, or the like is used.

  The second column B is formed in a hollow shape, and a wiring 7b for supplying electric power to the first drive motor 7 passes through the second column B. Further, the third support column C is formed hollow, and a wiring 10b for supplying power to the second drive motor 10 passes through the third support column C. With these configurations, the wirings 7b and 10b are not exposed to the outside and are safe and the appearance of the apparatus is also improved.

  The armature 3 is arranged so as to surround the magnetic pole part 2a of the rotor 2, and as shown in FIG. Coil portions 3a (three in the drawing) are provided. In addition, three slip rings 12 that are electrically connected to the respective coil portions 3 a are arranged in parallel on the outer peripheral portion of the armature 3. A current collecting shoe 13 is electrically connected to each slip ring 12, and electricity can be taken out from the current collecting shoe 13 through a power transmission line.

  Next, the operation of the generator according to the embodiment of the present invention will be described. First, the first drive motor 7 is driven to rotate the third disk 8 and the second drive motor 10 is driven to rotate the fourth disk 11. At this time, the third disk 8 and the fourth disk 11 are rotated in opposite directions.

  The rotational force of the third disk 8 is transmitted to the first disk 4, whereby the rotor 2 connected to the first disk 4 is rotated in one direction. On the other hand, the rotational force of the fourth disk 11 is transmitted to the second disk 5, whereby the armature 3 connected to the second disk 5 is rotated in the other direction opposite to the one direction.

  According to the generator according to the embodiment of the present invention, since the rotor 2 and the armature 3 are rotated in opposite directions, the rotor 2 and the armature 3 are compared with the case where only the rotor 2 is rotated. It is possible to increase the relative speed of and to generate a larger induced electromotive force. Further, since it is not necessary to rotate the rotor 2 at a high speed, it is possible to prevent a failure of parts or the entire generator due to centrifugal force or natural vibration due to the high speed rotation.

  In addition, since the rotor 2 and the armature 3 are rotated by the drive motors 7 and 10 instead of the external rotating body such as a bicycle tire, stable power supply is possible.

  In addition, the size and number of the first to fourth disks 4, 5, 8, and 11 can be appropriately changed, and the rotor 2 and the armature 3 can be rotated by separate drive motors 7 and 10, respectively. It is easy to change the setting of the relative speed between the child 2 and the armature 3, and the generated power can be freely adjusted.

  FIG. 5 is a perspective view showing a modification of the armature 3. As shown in FIG. 5, a plurality of holes 19 for allowing air to enter the surface of the armature 3 may be opened. Usually, heat is generated in the armature 3 due to the load current flowing in the coil portion 3a. Therefore, when the armature 3 rotates, air enters through the holes 19 and the inside of the armature 3 can be cooled. In addition, the formation of the hole 19 can reduce the weight of the armature 3 and increase the rotation efficiency.

  FIG. 6 shows another modification of the armature 3, (A) is a side view, (B) is a plan view showing a lift plate, and (C) is a bottom view showing a lift stabilizing plate.

The ring 24 may be overlapped in an idle state. The outermost ring 24 and the current collecting shoe 13 are electrically connected (contacted). As a result, the rotational force is not transmitted to the outermost ring 24 and hardly rotates, so that the contact state with the current collecting shoe 13 becomes good and electricity can be stably taken out. In addition, by attaching a lubricant such as oil between the rings 24, the armature 3 can be smoothly rotated and noise due to friction can be prevented.

The contact state between the outer ring 26a and the current collecting shoe 13 becomes good, and electricity can be taken out stably. In addition, oil etc. may be put into the storage part of the bearing 25, and friction with the outer side ring 26a may be reduced.
