Description

The present invention relates to a magnetic rotation device and a power generation device incorporating the same, and particularly to a magnetic rotation technique that utilizes repulsive force generated by magnetic force between magnets for rotation.

Permanent magnet motors and generators have been well known as application examples of magnetic rotation devices that utilize repulsion generated by magnetic force between magnets for rotation. A magnetic rotation device generally has a structure in which a rotor is rotated by utilizing the repulsive force generated when the opposing rotor-side magnets and fixed-side magnets have the same magnetic polarity.

However, the repulsive force caused by magnetic poles of the same polarity becomes positive energy that promotes rotor rotation when the rotor-side magnet and stationary-side magnet separate due to rotor rotation, but inhibits rotor rotation when they approach each other. becomes negative energy. Further, since the magnet has an N pole and an S pole, in addition to the repulsive force caused by the magnetic poles of the same polarity, an attractive force due to different magnetic poles is also generated. Therefore, in order to increase the rotational force of a magnetic rotation device, how can we effectively use only the repulsive force that occurs when the rotor side magnets and fixed side magnets are separated by the rotation of the rotor, that is, the energy that promotes the rotation of the rotor? It is important to be able to take it out.

As a method for solving this problem, for example, a magnetic rotation device disclosed in Patent Document 1 has been proposed. The magnetic rotation device of Patent Document 1 includes a rotating shaft, a rotor in which a plurality of magnets are arranged at the end of the outer periphery so that the magnetic poles are arranged in the radial direction, and the same number of magnets as the magnets in the rotor are arranged in the radial direction. a stator disposed facing the magnets of the rotor; a magnetically shielding rotating body having alternating slits and shielding plates made of ferromagnetic material; and a rotor detection sensor disposed near the rotor. , a magnetic shielding rotating body detection sensor installed near the magnetically shielding rotating body. The rotor detection sensor and the magnetically shielded rotating body detection sensor insert the magnetically shielded rotating body between the rotor magnet and the stator magnet in a timely manner. This artificially creates an imbalance between the repulsive force and attractive force between the rotor magnet and the stator magnet, minimizes the rotational energy acting in the negative direction in the rotation direction of the rotor, and The force is extracted as rotational energy.

Japanese Patent Application Publication No. 2014-200159

However, as in the magnetic rotating device of Patent Document 1, a method of inserting a magnetically shielding rotating body between a rotor magnet and a stator magnet in a timely manner using a rotor detection sensor and a magnetically shielding rotating body detection sensor This method has the disadvantage that it is mechanically complicated and that timing shifts are likely to occur depending on the detection accuracy of the sensor. When a timing difference occurs, it is not possible to effectively extract the repulsive force, that is, positive energy, when the rotor-side magnet and the stationary-side magnet are separated.

In addition, magnets have N and S poles, and in addition to repulsive force due to magnetic poles of the same polarity, attractive force due to different magnetic poles is also generated, so a magnetic shielding rotating body is installed between the rotor magnet and stator magnet. By simply inserting the magnets, it is not possible to effectively extract the repulsive force that occurs when the magnets on the rotor side and the magnets on the fixed side are separated by rotation of the rotor.

The present invention was developed in view of the above circumstances, and although it has a simple structure, the present invention promotes the repulsive force when the magnets on the rotor side and the magnets on the fixed side are separated by rotation of the rotor, that is, the rotation of the rotor. An object of the present invention is to provide a magnetic rotation device that can more effectively extract positive energy, and a power generation device incorporating the same.

In order to achieve the above object, the magnetic rotating device of the present invention is a magnetic rotating device that utilizes the magnetic force of a magnet as a rotating force. a circular rotor that rotates with the rotation center at The magnetic poles are arranged with equally spaced gaps along the rotational direction of the rotating shaft, and the N and S poles are located in the radial direction perpendicular to the axis of the rotating shaft, and all the outer magnetic poles on the outside in the radial direction have the same polarity. The rotor-side magnet part consists of a plurality of bar magnets arranged so that the rotor-side magnet part is arranged so that gaps are formed at equal intervals in the circumferential direction on the inner peripheral surface of the fixed part, and the magnet part is arranged in a radial direction perpendicular to the axis of the rotating shaft. A fixed side consisting of a plurality of bar magnets arranged such that N and S poles are located in the direction and the inner magnetic pole facing the rotor-side magnet has the same polarity as the outer magnetic pole of the rotor-side magnet. The magnetic force of the bar magnet is located on the downstream surface of the bar magnet of the rotor-side magnet section, which is the opposing surface of the bar magnet of the fixed-side magnet section of the rotor-side magnet section. A rotor-side magnetic force shielding plate is provided to cut off the magnetic force, and among the inner facing surfaces of the bar magnets of the fixed-side magnet section that are opposite to the bar magnets of the rotor-side magnet section, there is a bar on the upstream surface when viewed from the rotational direction of the rotor. A fixed-side magnetic force blocking plate is provided to block the magnetic force of the magnet, so that the magnetic poles on the entire surface of the rotor-side magnet part have the same polarity as the outer magnetic poles, and the magnetic poles on the entire surface of the fixed-side magnet part have the same polarity as the inner magnetic poles. It is characterized by the fact that it is made to be .

According to the present invention, among the outer facing surfaces of the bar magnets of the rotor-side magnet portion, which are the opposing surfaces to the bar magnets of the fixed-side magnet portion, the downstream surface as seen from the rotational direction of the rotor blocks the magnetic force of the bar magnets. A rotor-side magnetic force shielding plate is installed. Of the inner facing surfaces of the bar magnets of the fixed side magnet section, which are opposing surfaces to the bar magnets of the rotor side magnet section, the upstream surface as viewed from the rotational direction of the rotor has a fixed side magnetic force that blocks the magnetic force of the bar magnet. A blocking plate was installed.

As a result, when the magnets on the rotor side and the magnets on the fixed side approach each other due to the rotation of the rotor, the magnetic force from the bar magnets is blocked by the rotor side magnetic force blocking plate and the fixed side magnetic force blocking plate, while the magnets on the rotor side When the fixed side magnets are separated, the magnetic force from the bar magnets is not blocked. Therefore, positive rotational energy that promotes the rotation of the rotor can be effectively extracted, and the rotation of the rotor can be lightened.

That is, when the bar magnets of the rotor-side magnet part and the bar magnets of the stationary-side magnet part are separated, the repulsive force is made easier to utilize. Therefore, although the structure is simple, it is possible to effectively utilize the repulsive force generated when the magnets on the rotor side and the magnets on the fixed side are separated by rotation of the rotor.

In an aspect of the present invention, the magnetic pole of the concave surface of the gap formed between adjacent bar magnets of the rotor-side magnet section is the same as the outer magnetic pole that is the magnetic pole of the outer facing surface of the bar magnet of the rotor-side magnet section.

Preferably, the magnetic poles on the entire surface of the rotor-side magnet section have the same polarity as the outer magnetic poles, and the magnetic poles on the entire surface of the fixed-side magnet section have the same polarity as the inner magnetic poles. This specifically shows a preferred embodiment of the above configuration.

In an aspect of the present invention, the rotor-side magnetic force blocking plate is provided on the downstream half of the outer facing surface of the bar magnet, and the stationary side magnetic force blocking plate is provided on the upstream half of the inner opposing surface of the bar magnet. It is preferable that

As a result, the rotor rotates with almost no repulsive force until the bar magnets in the rotor-side magnet part and the bar magnets in the fixed-side magnet part face each other, and the bar magnets in the rotor-side magnet part turn to the bar magnets in the fixed-side magnet part. When it passes through a bar magnet, a repulsive force is generated. Therefore, the repulsive force generated when the magnets on the rotor side and the magnets on the fixed side are separated by rotation of the rotor can be extracted more effectively.

In an aspect of the present invention, the rotor-side magnetic force blocking plate may have an eaves portion extending from the end of the downstream surface of the bar magnet, and the fixed portion magnetic force blocking plate may have an eaves portion extending from the end of the upstream surface of the bar magnet. preferable. Thereby, when the bar magnet of the rotor-side magnet part and the bar magnet of the fixed-side magnet part approach each other due to rotation of the rotor, the magnetic force generated from the bar magnet can be further blocked.

In the aspect of the present invention, it is preferable that the rotor side magnetic force blocking plate and the stationary side magnetic force blocking plate are made of ferromagnetic material.

In this way, by configuring the iron plate and a plurality of magnets, the absorption power for absorbing magnetic force can be increased, so that magnetic force can be blocked more effectively.

In an aspect of the present invention, it is preferable to fill the gap with a non-magnetic material. As a result, the bar magnets are firmly fixed, so that it is possible to prevent the bar magnets from shifting due to mutual repulsive forces between the bar magnets in the rotor-side magnet section and the bar magnets in the fixed-side magnet section.

FIG. In addition, in the front cross-sectional view of FIG. 2(B), in order to make the cross-sectional structure diagram easier to understand, the main components of the device frame, rotating shaft, rotor, fixed part, bar magnet, flywheel, and rotor-side magnetic force shielding plate are shown. Although the fixed side magnetic force shielding plate is hatched, the hatching of other members is omitted. This omission of hatching also applies to the front sectional views from FIG. 2 onwards. Note that a permanent magnet was used as the bar magnet.

As shown in FIG. 2, the magnetic rotation device 16 according to the first embodiment of the present invention mainly includes a rotatably supported rotating shaft 28, a rotor 34, a fixed part 36, and a rotor-side magnet part 38. , a fixed side magnet section 40, a rotor side magnetic force blocking plate 42, and a fixed side magnetic force blocking plate 44.

In FIG. 2, the device frame 20 is formed into a rectangular cylindrical shape with an open surface in the axial direction of the rotating shaft 28 of the rotor 34, but it may also be formed into a cylindrical shape.

As shown in FIG. 1, the rotating shaft 28 is rotatably supported by a pair of bearings 26 disposed outside the device frame 20, and a rotor 34 is mounted on both sides of the rotating shaft 28 with the rotor 34 in between. A pair of flywheels 46 having a diameter larger than the diameter is provided. A certain distance is maintained between the rotor 34 and the flywheel 46 by a shaft collar 48.

The rotor 34 has a circular shape as shown in FIG. 2A, and its center is fixed to the rotating shaft 28. As a result, the rotor 34 rotates together with the rotating shaft 28 with the axis of the rotating shaft 28 as the rotation center. The rotor 34 in this embodiment has a cylindrical fitting tube 34B that fits into the rotating shaft 28 at the center position of the disk-shaped rotor main body 34A that is perpendicular to the rotating shaft 28. It has a cylindrical outer ring tube 34C on the outside. Further, a cylindrical cylinder 50 for fixing the rotor side magnet part 38 is provided on the outside of the outer ring cylinder 34C.

Further, as shown in FIG. 2B, a pair of opposing rotor-side side covers 52 are supported on the rotor main body 34A. The side cover 52 is preferably made of a non-magnetic material such as stainless steel. The side cover 52 is formed into a ring plate shape with an open center, and the side covers 52 are connected to each other by a plurality of connecting bolts 54. One of the plurality of connecting bolts 54 passes through a hole formed in a bar magnet 66 (first bar magnet, hereinafter simply referred to as "bar magnet 66") . Thereby, the bar magnet 66 is supported by the side cover 52 via the connecting bolt 54.

The fixing portion 36 is fixed to the device frame 20. The fixing portion 36 is provided outside the rotor 34 so as to surround the rotor 34, and has an inner circumferential surface concentric with the rotor 34. The fixing part 36 of this embodiment has a cylindrical outer tube 56 and a cylindrical inner tube 58, and connects the device frame 20 and the outer tube 56 at a plurality of locations with connecting bolts 60. It has a structure in which the inner cylinder 58 and the inner cylinder 58 are connected and fixed at a plurality of locations with connection adjustment bolts 62. The rotor 34 described above is disposed inside the inner cylinder 58, and the inner cylinder 58 has an inner circumferential surface concentric with the rotor 34. The fixed side magnet portion 40 is provided on the inner circumferential surface of the inner cylinder 58.

As shown in FIG. 2A, the inner cylinder 58 has a structure in which a plurality of arcuate block plates 58A are arranged in a ring shape. In order to provide the fixed side magnet portion 40 on the inner peripheral surface of the inner cylinder 58, first fix the bar magnet 66 to the arc-shaped block plate 58A, and then use the connection adjustment bolt 62 to attach the bar magnet 66 to the arc-shaped block plate 58A from the outer cylinder 56. This is done by arranging the arcuate block plates 58A in a ring shape while adjusting the distance between them.

Further, as shown in FIG. 2B, a pair of opposing fixed side side covers 61, 61 are supported on the outer cylinder 56. The side cover 61 is preferably made of a non-magnetic material such as stainless steel. The side cover 61 is formed into a ring plate shape having a center opening larger in diameter than the rotor side side cover 52, and the side covers 61 are connected to each other by a plurality of connecting bolts 63. One of the plurality of connecting bolts 63 passes through a hole formed in a bar magnet 70 (second bar magnet, hereinafter simply referred to as "bar magnet 70") . Thereby, the bar magnet 70 is supported by the side cover 61 via the connecting bolt 63.

As shown in FIG. 2A, the rotor-side magnet portion 38 has gaps 64 at equal intervals along the rotor rotation direction A in a cylindrical cylinder 50 on the outer peripheral surface of the rotor 34. It is constructed by a plurality of bar magnets 66 being arranged and fixed. Thereby, the rotor-side magnet section 38 is formed as a magnet section in which a plurality of bar magnets 66 are arranged circularly at equal intervals. Although FIG. 2A shows an example in which 18 bar magnets 66 are arranged, the number is not limited to this.

The cylindrical tube 50 to which the bar magnet 66 is fixed is preferably formed of a ferromagnetic material such as an iron plate. Moreover, as a method for fixing the bar magnet 66, any method may be used as long as the bar magnet 66 is fixed to the cylindrical tube 50, but it is preferable to firmly adhesively fix the bar magnet 66 with an adhesive.

In this way, by making the cylinder 50 a ferromagnetic material, the bottom surface 66F (Fig. 3 , see FIGS. 4 and 8). This allows the magnetic force from the portion covered with the ferromagnetic material to be weakened.

The plurality of bar magnets 66 of the rotor-side magnet section 38 are arranged so that the N pole and the S pole are located in the radial direction perpendicular to the axis of the rotating shaft, and the outer magnetic poles on the outside in the radial direction all have the same polarity. be done. In this embodiment, the north pole of the bar magnet 66 is arranged as the outer magnetic pole, but the bar magnet 66 may be arranged so that the south pole becomes the outer magnetic pole.

As shown in FIG. 2A, the stationary magnet section 40 has gaps 68 at equal intervals in the circumferential direction on the inner circumferential surface of the fixed section 36, that is, on the inner circumferential surface of the cylindrical inner cylinder 58. It is constructed by having a plurality of bar magnets 70 arranged and fixed. As a result, the fixed-side magnet section 40 is formed as a magnet section in which a plurality of bar magnets 70 are arranged in a circle at equal intervals and is one size larger than the rotor-side magnet section 38 .

In this case, the arc-shaped block plate 58A constituting the inner tube 58 is also formed of a ferromagnetic material such as an iron plate for the same reason as the cylindrical tube 50 described above, and the bottom surface 70F of the bar magnet 70 is attached to the arc-shaped block plate 58A with adhesive. It is preferable to fix it firmly with (see FIG. 3, FIG. 4, and FIG. 8). Further, it is preferable that the number of bar magnets 70 in the fixed side magnet section 40 is the same as that in the rotor side magnet section 38.

The plurality of bar magnets 70 of the fixed side magnet section 40 have N poles and S poles located in a radial direction perpendicular to the axis of the rotating shaft 28, and inner magnetic poles on the side facing the rotor side magnet section 38 are located on the rotor side. They are arranged so as to have the same polarity as the outer magnetic pole of the side magnet portion 38. In this embodiment, the N pole of the bar magnet 70 is arranged as the inner magnetic pole, but if the outer magnetic pole of the rotor side magnet part 38 is the S pole, the inner magnetic pole of the fixed side magnet part 40 is also the S pole. I will make it happen.

The reason why there is a gap 64 (or gap 68) in the rotor side magnet part 38 and the fixed side magnet part 40 is that when adjacent bar magnets 66 (or bar magnets 70) are in contact with each other, the rotor rotation This is because it adversely affects the generation of repulsive force in direction A. Therefore, between the adjacent bar magnets 66 (or bar magnets 70) of the rotor side magnet part 38 and the fixed side magnet part 40, the width dimension of the bar magnet 66 (or bar magnet 70) as seen from the rotor rotation direction A is It is preferable to form the gap 64 (or gap 68) with a gap distance of about 1 to 2 times.

Next, the rotor side magnetic force blocking plate 42 and the fixed side magnetic force blocking plate 44 will be explained. In this embodiment, the outer magnetic pole of the bar magnet 66 of the rotor side magnet section 38 and the bar magnet 70 of the fixed side magnet section 40 The following explanation will be given in the case where the inner magnetic pole of the magnetic pole is the north pole.

FIG. 3 is a perspective view illustrating the rotor side magnetic force blocking plate 42 and the fixed side magnetic force blocking plate 44. A rotor-side magnetic force blocking plate 42 and a fixed-side magnetic force blocking plate 44 are fixed to each other.

As shown in FIG. 3, the rotor-side magnetic force blocking plate 42 blocks the magnetic force of the bar magnet 66, and is a surface of the fixed-side magnet portion 40 of the bar magnet 66 of the rotor-side magnet portion 38 that faces the bar magnet 70. It is provided on the downstream surface viewed from the rotor rotation direction A among the outer facing surfaces 66A.

The fixed side magnetic force shielding plate 44 is for blocking the magnetic force of the bar magnet 70, and has an inner facing surface 70A which is a surface facing the bar magnet 66 of the rotor side magnet section 38 of the bar magnet 70 of the fixed side magnet section 40. Among them, it is provided on the upstream surface as viewed from the rotor rotation direction A.

This blocks the magnetic force from coming out from the downstream surface of the outer facing surface 66A, which is the magnetic pole surface of the bar magnet 66 of the rotor-side magnet portion 38, where the magnetic force is strongest. Moreover, the magnetic force is blocked from coming out from the upstream surface of the inner facing surface 70A, which is the magnetic pole surface of the bar magnet 70 of the fixed side magnet part 40, where the magnetic force is strongest.

In this case, as shown in FIG. 3, of the outer facing surface 66A of the bar magnet 66 of the rotor side magnet section 38, the surface downstream of the half center line M as seen from the rotor rotation direction A is connected to the rotor side magnetic force shielding plate 42. It is preferable to cover it with On the other hand, it is preferable to cover the upstream side of the inner facing surface 70A of the bar magnet 70 of the fixed side magnet part 40 with the rotor side magnetic force shielding plate 42 from the center line M of the half viewed from the rotor rotation direction A.

Furthermore, it is more preferable that the rotor-side magnetic force shielding plate 42 forms an eaves portion 42A extending from the end of the downstream surface of the outer facing surface 66A of the bar magnet 66. Further, it is more preferable that the fixed side magnetic force shielding plate 44 forms an eaves portion 44A extending from the end of the upstream surface of the inner facing surface 70A of the bar magnet 70.

FIG. 4 is a modification of FIG. 3. As shown in FIG. 4, the downstream half of the outer facing surface 66A of the bar magnet 66 of the rotor side magnet portion 38 (the surface downstream of the center line M) is shaved to create a stepped surface that is recessed than the outer facing surface 66A. 67, and the rotor-side magnetic force shielding plate 42 is embedded in this stepped surface 67. Thereby, the upstream surface of the outer facing surface 66A of the bar magnet 66 where the rotor-side magnetic force blocking plate 42 is not provided and the surface of the rotor-side magnetic force blocking plate 42 can be made flush with each other.

Similarly, the upstream half of the inner facing surface 70A of the bar magnet 70 of the fixed side magnet portion 40 (the surface upstream of the center line M) is shaved to form a step surface 71 that is more recessed than the inner facing surface 70A. A fixed side magnetic force shielding plate 44 is embedded in this stepped surface 71. Thereby, the downstream surface of the inner facing surface 70A of the bar magnet 70 of the fixed side magnet portion 40 where the fixed side magnetic force blocking plate 44 is not provided can be made flush with the surface of the fixed side magnetic force blocking plate 44.

Therefore, in FIG. 4, the distance between the opposing surfaces of the bar magnets 66 and 70 can be made closer than in FIG. 3, and a larger repulsive force can be obtained. Note that, as shown in FIG. 3, when the rotor side magnetic force blocking plate 42 and the fixed side magnetic force blocking plate 44 are fixed to the outer facing surface 66A and the inner facing surface 70A of the bar magnets 66, 70, the bar magnets 66, 70 are It is preferable that the distance between them be as close as possible without contact.

In the following description, the rotor side magnetic force blocking plate 42 and the fixed side magnetic force blocking plate 44 are respectively fixed to the opposing surfaces of the bar magnet 66 of the rotor side magnet section 38 and the bar magnet 70 of the stationary side magnet section 40. 3 will be explained, but it goes without saying that a modified example in which it is embedded in the stepped surfaces 67 and 71 in FIG. 4 may also be used.

5 to 7 are configuration examples of the rotor-side magnetic force blocking plate 42 and the fixed-side magnetic force blocking plate 44. Since the rotor side magnetic force blocking plate 42 and the fixed side magnetic force blocking plate 44 have the same configuration, only the rotor side magnetic force blocking plate 42 will be described in detail. In FIGS. 5 to 7, the center line P vertically indicates the half-plane position of the outer facing surface 66A of the bar magnet 66 and the inner facing surface 70A of the bar magnet 70 in the rotor rotational direction A. It has the same meaning as the center line M shown horizontally in 4.

The rotor-side magnetic force blocking plate 42 shown in FIG. 5 is made of a ferromagnetic material such as iron, and in FIG. 5 it is formed as a laminated iron plate 72 in which a plurality of thin iron plates are laminated. Since the ferromagnetic material absorbs the magnetic flux from the bar magnet 66, it is possible to weaken the magnetic force from the portion covered with the ferromagnetic material. In this way, by using the laminated iron plates 72, a thin plate-shaped magnet layer is formed on the rotor-side magnetic force shielding plate 42, so that magnetic flux can be absorbed more easily than when a single iron plate is used.

As the ferromagnetic material, in addition to iron, silicon iron (iron mixed with a small amount of silicon), perlomy (an alloy whose main component is nickel), etc. can also be used. The fixed side magnetic force shielding plate 44 also has a similar configuration.

The rotor side magnetic force blocking plate 42 in FIG. 6A is provided with a laid magnet 74 in which a plurality of small square bar-shaped blocking magnets 74A (permanent magnets) are laid on the surface of the laminated iron plate 72 in FIG. The plurality of blocking magnets 74A constituting the installed magnet 74 have a bar shape from the front side to the back side in FIG. 6A, and are arranged along the rotor rotation direction A. In the installed magnets 74, the magnetic poles on the laminated iron plate 72 side of adjacent blocking magnets 74A are alternately different. The fixed side magnetic force shielding plate 44 also has a similar configuration.

Further, the rotor-side magnetic force blocking plate 42 in FIG. 6B is a modification of the rotor-side magnetic force blocking plate 42 in FIG. 6A. (A) of FIG. 6B is a perspective view of the rotor-side magnetic force shielding plate 42 provided on the bar magnet 66, (B) is a plan view of (A) seen from the direction of arrow G, and (C) is a perspective view of (A) It is a side view seen from the direction of H. As can be seen from these figures, in the rotor-side magnetic force blocking plate 42 of FIG. They are arranged in a direction perpendicular to the That is, the installed magnets 74 of the rotor-side magnetic force blocking plate 42 in FIG. 6B are obtained by rotating the installed magnets 74 of the rotor-side magnetic force blocking plate 42 in FIG. 6A by 90 degrees on the outer facing surface 66A of the bar magnet 66. The fixed side magnetic force shielding plate 44 also has a similar configuration.

The rotor-side magnetic force blocking plate 42 in FIG. 7 is similar to that shown in FIG. 6 in that a laying magnet 74 is provided in which a plurality of small square bar-shaped blocking magnets 74A (permanent magnets) are placed on the surface of a laminated iron plate 72. , the blocking magnet 74A has a trapezoidal shape. The fixed side magnetic force shielding plate 44 also has a similar configuration.

Here, similarly to the interrupting magnet 74A shown in FIG. 6B, the interrupting magnet 74A may also be arranged so that its longitudinal direction faces the rotor rotation direction A. As a result, the blocking magnets 74A are arranged in a direction perpendicular to the rotor rotation direction A, similar to FIG. 6B.

Like the rotor side magnetic force blocking plate 42 and fixed side magnetic force blocking plate 44 in FIGS. 6A, 6B, and 7, a laying magnet 74 has a plurality of small square blocking magnets 74A (permanent magnets) laid on the surface of a laminated iron plate 72. By providing the laminated iron plate 72, the absorption power for absorbing magnetic force can be increased compared to the case where only the laminated iron plate 72 is used, so that the magnetic force can be blocked more reliably.

Although not shown, in FIGS. 6A, 6B, and 7, a magnetic material or a nonmagnetic material may be interposed between adjacent blocking magnets 74A of the installed magnets 74. For example, referring to FIG. 6B (B), among the plurality of cutoff magnets 74A of the installed magnets 74, the cutoff magnet 74A described as an S pole can be replaced with a magnetic material or a nonmagnetic material. In this case, the blocking magnets 74A described as N poles and magnetic materials or non-magnetic materials are alternately arranged. Alternatively, among the plurality of blocking magnets 74A of the installed magnets 74, the blocking magnet 74A described as N pole can be replaced with a magnetic material or a non-magnetic material. In this case, the blocking magnets 74A, which are described as S poles, and magnetic materials or non-magnetic materials are alternately arranged.

In addition, in FIGS. 5 to 7, the length L of the eaves portion 42A of the rotor-side magnetic force shielding plate 42 and the length L of the eaves portion 44A of the fixed-side magnetic force shielding plate 44 are determined by the adjacent bar magnets. It is preferable to set it in relation to the width W (see FIG. 5) of the gap portions 64 and 68 between the 66 in the rotor rotation direction A (see FIG. 5). That is, as described above, the length of the eaves portion 44A is determined in relation to the fact that the width of the gaps 64 and 68 is preferably from one to two times the width W of the bar magnets 66 and 70 in the rotor rotation direction A. Considering L, the length L of the eaves portion 44A is preferably about 1/3 to 1/4 of the width W of the bar magnet 66 in the rotor rotation direction A.

Next, with reference to FIG. 8, the operation of the magnetic rotating device 16 of the first embodiment of the present invention configured as described above will be explained. In the following explanation, a repulsive force that generates positive rotational energy that promotes the rotation of the rotor 34 is referred to as a "positive repulsive force," and a repulsive force that generates negative rotational energy that inhibits the rotation of the rotor 34 is referred to as a "positive repulsive force." Let's call it "negative repulsive force."

FIG. 8A shows a state in which the bar magnet 66 of the rotor-side magnet portion 38 and the bar magnet 70 of the fixed-side magnet portion 40 are approaching each other due to the rotation of the rotor 34. FIG. 8B shows a state in which the bar magnet 66 of the rotor-side magnet section 38 and the bar magnet 70 of the fixed-side magnet section 40 are aligned. (C) of FIG. 8 shows a state in which the bar magnet 66 of the rotor-side magnet section 38 and the bar magnet 70 of the fixed-side magnet section 40 are spaced apart. Note that as a rotational drive source for rotating the rotor 34, for example, the motor 12 is used as shown in FIG.

As shown in FIG. 8(A), when the bar magnet 66 of the rotor-side magnet portion 38 and the bar magnet 70 of the fixed-side magnet portion 40 approach each other due to the rotation of the rotor 34, the rotor The magnetic force on the downstream surface of the outer facing surface 66A of the side magnet portion 38 is blocked by the rotor side magnetic force blocking plate 42. Further, the magnetic force on the upstream surface of the inner facing surface 70A of the fixed side magnet portion 40 is blocked by the fixed side magnetic force blocking plate 44. As a result, when the bar magnet 66 of the rotor-side magnet section 38 and the bar magnet 70 of the fixed-side magnet section 40 approach each other, the bar magnets 66 and 70 are removed by the rotor-side magnetic force blocking plate 42 and the fixed-side magnetic force blocking plate 44. Blocks magnetic force.

As shown in FIG. 8B, a negative repulsive force is generated between the bar magnets 66 and 70 until the bar magnet 66 of the rotor side magnet section 38 and the bar magnet 70 of the stationary side magnet section 40 are in a straight line state. The rotor 34 rotates in a difficult state.

As shown in FIG. 8C, when the bar magnet 66 of the rotor side magnet section 38 and the bar magnet 70 of the stationary side magnet section 40 are separated, the rotor side magnet section 38 Since the upstream surface that does not have the rotor-side magnetic force blocking plate 42 of the outer facing surface 66A is exposed, the magnetic force on the upstream surface is not blocked. Further, since the downstream surface of the inner facing surface 70A of the fixed side magnet section 40 that does not have the fixed side magnetic force blocking plate 44 is exposed, the magnetic force on the downstream surface is not blocked. As a result, when the bar magnet 66 of the rotor-side magnet section 38 and the bar magnet 70 of the fixed-side magnet section 40 are separated, a positive repulsive force is generated between the upstream surface of the bar magnet 66 and the downstream surface of the bar magnet 70. Occur.

In this case, as explained in FIGS. 3 and 4, the rotor-side magnetic force blocking plate 42 is provided on the downstream surface of half of the bar magnet 66 of the rotor-side magnet section 38, and the half of the bar magnet 70 of the fixed-side magnet section 40 is provided with the rotor-side magnetic force blocking plate 42. It is preferable to provide a fixed side magnetic force shielding plate 44 on the upstream surface of the magnetic force shielding plate 44 . As a result, the rotor 34 rotates in a state in which negative repulsive force is difficult to generate until the bar magnets 66 and 70 are in a straight line. Then, when the bar magnet 66 of the rotor-side magnet section 38 passes the bar magnet 70 of the fixed-side magnet section 40 (passes through a straight line state), a positive repulsive force is generated.

In this manner, the magnetic rotation device 16 of the first embodiment effectively uses only the positive repulsion force that promotes the rotation of the rotor 34 by providing the rotor-side magnetic force blocking plate 42 and the fixed-side magnetic force blocking plate 44. Since the rotor 34 can be taken out at any time, the rotation of the rotor 34 is lightened .

Further, by providing the eaves portions 42A and 44A on the rotor side magnetic force blocking plate 42 and the stationary side magnetic force blocking plate 44, respectively, the magnetic force blocking effect is increased. Thereby, when the bar magnet 66 of the rotor-side magnet section 38 and the bar magnet 70 of the stationary-side magnet section 40 approach each other , negative repulsive force is less likely to be generated.

That is, the magnetic rotation device 16 according to the first embodiment of the present invention promotes the rotation of the rotor 34 only when the bar magnets 66 of the rotor-side magnet section 38 and the bar magnets 70 of the fixed-side magnet section 40 are separated from each other. The energy to do this was generated.

Furthermore, as explained in FIG. 2, since the flywheel 46 is provided on the rotating shaft 28, the moment of inertia at which the rotor 34 rotates can be increased. Thereby, the positive repulsive force generated between the rotor-side magnet section 38 and the fixed-side magnet section 40 can be converted into smooth rotational movement of the rotor 34 .

[Second embodiment of magnetic rotation device]
As explained in the magnetic rotation device 16 of the first embodiment of the present invention, between the adjacent bar magnets 66 (or between the bar magnets 70) of the rotor side magnet section 38 and the fixed side magnet section 40, It has a gap 64 (or gap 68) having a concave surface.

However, by having this gap portion 64 (or gap portion 68), as shown in FIGS. 3 and 4, the bar magnet 66 of the rotor side magnet portion 38 has a surface other than the outer facing surface 66A, i.e. The front surface 66B and the rear surface 66C viewed from the rotor rotation direction A are exposed. Similarly, the bar magnet 70 of the fixed side magnet part 40 has surfaces other than the inner facing surface 70A, that is, the front surface 70B and the rear surface 70C as viewed from the rotor rotation direction A, are exposed.

Although not due to the gap 64 (or gap 68), the left surface 66D and right surface 66E of the bar magnet 66, which are orthogonal to the rotor rotation direction A, are also exposed. Similarly, the left surface 70D and right surface 70E of the bar magnet 70, which are orthogonal to the rotor rotation direction A, are also exposed.

By not exposing the side surfaces of the bar magnets 66, 70, that is, the front surfaces 66B, 70B, the rear surfaces 66C, 70C, the left surfaces 66D, 70D, and the right surfaces 66E, 70E, the attractive force between the bar magnets 66, 70 can be further enhanced. It can be made less likely to occur. The attractive force between the bar magnets 66 and 70 is a factor that reduces the positive repulsive force that promotes rotation of the rotor 34. Therefore, by reducing the attractive force, the positive repulsive force can be extracted more effectively.

Therefore, in the magnetic rotation device 76 according to the second embodiment of the present invention, the magnetic poles on the entire surface (all surfaces) of the rotor-side magnet portion 38 are set to have the same polarity as the outer magnetic pole, which is the magnetic pole on the outer facing surface 66A. At the same time, the magnetic poles on the entire surface (all surfaces) of the fixed-side magnet section 40 are made to have the same polarity as the inner magnetic pole, which is the magnetic pole of the inner opposing surface 70A, so that the magnetic poles between the rotor-side magnet section 38 and the fixed-side magnet section 40 are The structure is such that it is difficult to generate suction force.

(A) of FIG. 9 is a side view of a magnetic rotation device 76 according to the second embodiment of the present invention when the rotor rotation direction A is taken as the front, and (B) is a side view of the magnetic rotation device 76 of the second embodiment of the present invention. FIG. 3 is a front sectional view taken along line -b. Note that the same members as those of the magnetic rotating device 16 of the first embodiment are given the same reference numerals and explained.

In the magnetic rotation device 76 according to the second embodiment of the present invention, as shown in FIG. The first auxiliary magnet 78 was provided so that the magnetic pole of the surface had the same polarity as the outer magnetic pole that was the magnetic pole of the outer facing surface 66A of the bar magnet 66. Similarly, the magnetic pole of the concave surface of the gap 68 formed between adjacent bar magnets 70 of the fixed side magnet part 40 has the same polarity as the inner magnetic pole that is the magnetic pole of the inner facing surface 70A of the bar magnet 70. A first auxiliary magnet 78 was provided.

Further, as shown in FIG. 9B, in the bar magnet 66 of the rotor-side magnet portion 38, the outside of the bar magnet 66 is formed on the left surface 66D and the right surface 66E when viewed from the rotor rotation direction A in FIGS. The second auxiliary magnet 80 and the third auxiliary magnet 82 were provided so as to have the same polarity as the outer magnetic pole that is the magnetic pole of the opposing surface 66A. Similarly, in the bar magnet 70 of the fixed side magnet part 40, the left surface 70D and the right surface 70E as viewed from the rotor rotation direction A in FIGS. A second auxiliary magnet 80 and a third auxiliary magnet 82 were provided so as to have the same polarity.

In the rotor-side magnet section 38 and the fixed-side magnet section 40, the mounting structure for attaching the first auxiliary magnet 78, second auxiliary magnet 80, and third auxiliary magnet 82 to the bar magnets 66, 70 is the same, so the rotor-side magnet section 38 will be explained in detail only.

The first auxiliary magnet 78 is fitted and fixed in the bottom part of the concave gap 64 between the bar magnets 66 of the rotor side magnet part 38 with the N pole facing upward (on the side facing the outer facing surface 66A of the bar magnet 66). do. That is, among the N-pole portion in the upper half and the S-pole portion in the lower half of the bar magnet 66, the front surface 66B and rear surface 66C of the S-pole portion are hidden by the first auxiliary magnet 78 (FIGS. 3 and 4). reference). Thereby, the gap 64 was made to be the same as the outer magnetic pole (N pole) that is the magnetic pole of the outer facing surface 66A of the bar magnet 66.

In addition, as shown in FIG. 9B, a second auxiliary magnet 80 and a third auxiliary magnet 82 are placed between the bar magnet 66 and the pair of side covers 61, 61 described above, and a side plate for fixing the magnet. 83, respectively. The side plate 83 is preferably made of a non-magnetic material such as stainless steel. Further, the side plate 83 is supported by the cylindrical tube 50 of the rotor 34. In this case, the rotor rotation direction A of the S-pole portion is between the N-pole portion of the upper half on the side of the outer facing surface 66A of the bar magnet 66 and the S-pole portion of the lower half on the opposite side of the outer facing surface 66A. The left side 66D (see FIGS. 3 and 4) and the right side 66E (see FIGS. 3 and 4) viewed from above are hidden by the second auxiliary magnet 80, respectively. Furthermore, the N pole side of the second auxiliary magnet 80 was made to face the N pole side of the bar magnet 66. Further, the third auxiliary magnet 82 is arranged to hide the S-pole portion of the second auxiliary magnet 80, and the N-pole and S-pole of the third auxiliary magnet are The directions were set to be perpendicular to each other.

Thereby, the left surface 66D and right surface 66E of the S pole portion of the bar magnet 66 are made to be the same as the outer magnetic pole (N pole) that is the magnetic pole of the outer facing surface 66A of the bar magnet 66.

The purpose of the first auxiliary magnet 78, the second auxiliary magnet 80, and the third auxiliary magnet 82 is to ensure that the magnetic pole of the entire surface (all surfaces) of the rotor side magnet portion 38 has the same polarity as the outer magnetic pole, that is, the N pole. It is to do so. Therefore, if the exposed area of the S pole in the rotor-side magnet portion 38 is reduced, the arrangement of the first auxiliary magnet 78, the second auxiliary magnet 80, and the third auxiliary magnet 82 is the same as the arrangement example shown in FIG. 9(B). Not limited.

The above detailed description is about the attachment structure of the first auxiliary magnet 78, the second auxiliary magnet 80, and the third auxiliary magnet 82 arranged on the rotor side magnet part 38, but the same applies to the fixed side magnet part 40. As a result, the exposed area of the S pole in the rotor side magnet section 38 and the fixed side magnet section 40 can be made extremely small, so that the attractive force generated between the rotor side magnet section 38 and the fixed side magnet section 40 can be made extremely small. can be made extremely small. Therefore, the magnetic rotation device 76 of the second embodiment can extract the positive repulsive force that promotes the rotation of the rotor 34 even more effectively than the magnetic rotation device 16 of the first embodiment. .

Like the magnetic rotation device 76 of the second embodiment of the present invention described above, in addition to the configuration of the rotor side magnetic force blocking plate 42 and the fixed side magnetic force blocking plate 44, the first auxiliary magnet 78 and the second auxiliary magnet 80 By providing the third auxiliary magnet 82, the positive repulsive force that promotes the rotation of the rotor 34 is further increased, and the rotation of the rotor 34 is further reduced .

FIG. 10 is a partially enlarged front sectional view of a modification of the magnetic rotation device 76 of the second embodiment of the present invention shown in FIG. A modification of the magnetic rotation device 76 according to the second embodiment is configured such that the attractive force generated between the bar magnet 66 of the rotor-side magnet section 38 and the bar magnet 70 of the fixed-side magnet section 40 is further reduced. This is what I did. That is, in addition to the second auxiliary magnet 80 and the third auxiliary magnet 82, a fourth auxiliary magnet 84 and a ferromagnetic plate 86 are provided on the left surfaces 66D, 70D and right surfaces 66E, 70E of the bar magnets 66, 70. .

As shown in FIG. 10, the arrangement of the second auxiliary magnet 80 is the same as that in FIG. A third auxiliary magnet 82 and a fourth auxiliary magnet 84 were provided so that their poles faced each other. Further, the ferromagnetic plate 86, the third auxiliary magnet 82, and the fourth auxiliary magnet 84 are fixed to each other by the side plate 83.

In this way, by providing the ferromagnetic plate 86 on the S pole side of the third auxiliary magnet 82 and the fourth auxiliary magnet 84 that you do not want to expose, the ferromagnetic plate 86 can be attached to the third auxiliary magnet 82 and the fourth auxiliary magnet 84. It has the effect of blocking the magnetic force from the S pole side. Thereby, the attractive force generated between the rotor-side magnet section 38 and the stationary-side magnet section 40 can be made extremely small .

By the way, in this way, the magnetic poles on the entire surface (all surfaces) of the rotor side magnet section 38 are made to have the same polarity as the outer magnetic poles, and the magnetic poles on the entire surface (all surfaces) of the stationary side magnet section 40 are made to have the same polarity as the inner magnetic poles. If they have the same polarity, the repulsive force between the bar magnet 66 of the rotor-side magnet section 38 and the bar magnet 70 of the fixed-side magnet section 40 will become even stronger, and there is a possibility that the bar magnets 66 and 70 may be misaligned. .

Therefore, as shown in FIG. 11, a non-magnetic material (for example, plastic) is filled in the gap 64 between the bar magnets 66 of the rotor side magnet section 38 and the gap 68 between the bar magnets 70 of the fixed side magnet section 40. I tried to fill it with 88. This makes it difficult for the bar magnets 66 and 70 to be misaligned. At this time, not only the gap 64 between the bar magnets 66 of the rotor-side magnet section 38 and the gap 68 between the bar magnets 70 of the fixed-side magnet section 40 but also the rotor-side magnetic force shielding plates 42 arranged in plurality in the rotation direction It is preferable to similarly fill the space between the two with a filler 88 made of a non-magnetic material (for example, plastic) (see FIGS. 11, 8, etc.). Similarly, it is preferable to fill the spaces between the plurality of stationary magnetic force shielding plates 44 arranged in the rotational direction with a filler 88 made of a non-magnetic material (for example, plastic) (see FIGS. 11, 8, etc.).

Further, as shown in FIG. 11, the outer facing surface 66A side of the plurality of bar magnets 66 (the bar magnets 66 provided with the rotor-side magnetic force shielding plate 42) constituting the circular rotor-side magnet portion 38 is formed into a cylindrical shape. It is preferable to provide a rotor side band 96 that presses against the side of the rotor 50. The rotor side band 96 is made of a cylindrical hard material such as non-magnetic material (for example, stainless steel or plastic), and both widthwise ends of the rotor side band 96 are fixed to the side cover 52 described above. Thereby, even if the bar magnet 66 is fixed to the cylindrical tube 50 made of a ferromagnetic material only by magnetic force, it is possible to prevent the bar magnet 66 from peeling off from the cylindrical tube 50.

Similarly, the inner facing surfaces 70A of the plurality of bar magnets 70 (the bar magnets 70 with the fixed magnetic force shielding plates 44 provided) constituting the circular fixed magnet section 40 are fixed to be pressed against the inner cylinder 58. Preferably, side bands 98 are provided. The fixed side band 98 is similar to the rotor side band 96, and is made of a cylindrical hard material made of non-magnetic material (for example, stainless steel or plastic), and both widthwise ends of the fixed side band 98 are fixed to the side cover 61 described above. be done.

In this way, by filling the gaps 64 and 68 with the filler 88 and providing the rotor side band 96 and the stationary side band 98, the bar magnet 70 can be attached to the inner cylinder 58 made of ferromagnetic material using only magnetic force. Even when fixed, it is possible to reliably prevent the bar magnet 70 from shifting from being fixed or peeling off from the inner cylinder 58.

In this case, as shown in FIG. 11, the gaps 64 and 68 are completely filled with the filler 88, that is, flush with the outer facing surface 66A of the bar magnet 66 and the inner facing surface 70A of the bar magnet 70. It is preferable to fill the filler 88 as shown in FIG. Thereby, no gap is generated between the rotor-side band 96 and the filler 88, so that the rotor-side band 96 and the rotor-side band 96 can be firmly fixed.

[Third embodiment of magnetic rotation device]
FIG. 12 is a front sectional view of a magnetic rotation device 90 according to a third embodiment of the present invention, which is the same as the magnetic rotation device 16 according to the first embodiment and the magnetic rotation device 76 according to the second embodiment. The members will be described with the same reference numerals.

The magnetic rotation device 90 according to the third embodiment of the present invention has a flywheel 92 that has a larger diameter than the rotor diameter as the rotor 34 of the rotor-side magnet portion 38 and can increase the moment of inertia in the rotor rotation direction A. .

As shown in FIG. 12, the center portion of a disk-shaped flywheel 92 is fitted and supported by the rotating shaft 28, and the above-described cylindrical cylinder 50 is fixed to the outer periphery of the flywheel 92. The other configurations are the same as the magnetic rotation device 76 of the second embodiment.

As described above, the magnetic rotation device 90 according to the third embodiment of the present invention has the configurations of the rotor side magnetic force blocking plate 42 and the fixed side magnetic force blocking plate 44, the first auxiliary magnet 78, the second auxiliary magnet 80, and the second auxiliary magnet 80. In addition to the configuration with three auxiliary magnets 82, a flywheel 92 is used as the rotor 34. Thereby, the positive repulsive force generated between the rotor-side magnet section 38 and the stationary-side magnet section 40 can be directly transmitted to the peripheral edge portion, which is the radial end of the flywheel 92. Therefore, the positive repulsive force can be made to act more effectively as energy for promoting the rotation of the rotor 34 than when the flywheel 92 is provided on the rotating shaft 28. Thereby, the rotation of the rotor 34 can be made even lighter.

Note that a magnetic rotation device 90 according to the third embodiment of FIG. 12 is obtained by replacing the rotor 34 of the magnetic rotation device 76 according to the second embodiment of the present invention with a flywheel 92; The rotor 34 of the magnetic rotation device 16 of the first embodiment may be replaced with a flywheel 92.

[Fourth embodiment of magnetic rotation device]
FIG. 13 is a front cross-sectional view of a magnetic rotation device 94 according to a fourth embodiment of the present invention, which is constructed so that a plurality of the above-described magnetic rotation devices of the present invention are connected in series.

The magnetic rotation device 94 according to the fourth embodiment of the present invention includes the magnetic rotation device 16 according to the first embodiment, the magnetic rotation device 76 according to the second embodiment, and the magnetic rotation device 76 according to the third embodiment. Rotating devices 90 can be combined in various ways. In FIG. 13, one magnetic rotation device 76 of the second embodiment and two magnetic rotation devices 90 of the third embodiment are combined.

As a result, according to the magnetic rotation device 94 according to the fourth embodiment of the present invention, since a plurality of magnetic rotation devices 76 and 90 are connected in series, the rotation of the magnetic rotation device 94 can be made even more efficient. be able to.

The magnetic rotation devices 16, 76, 90, 94 of the present invention and the power generation device 10 incorporating the same have been described above. The magnetic rotating devices 16, 76, 90, and 94 of the third embodiment, the third embodiment, and the fourth embodiment can be incorporated in various combinations.

In addition, according to the magnetic rotation device 94 of the fourth embodiment of the present invention, a plurality of magnetic rotation devices 76 and 90 are connected in series; The same effect can also be obtained by arranging a plurality of bar magnets 66, 70 in the axial direction of the rotating shaft 28 in the single magnetic rotating device 16, 76, 90 described above.

For example, the bar magnets 66 and 70 (provided with the rotor side magnetic force blocking plate 42 and the stationary side magnetic force blocking plate 44) in FIG. A plurality of each (for example, three) are arranged.
