  Permanent magnets have the property of repelling each other when the same poles are brought closer to each other, and attracting each other when different poles are brought closer to each other. Conventionally, there has been a concept of generating a linear motion of a member by using a force (repulsive force) or a force (attractive force) of repulsive permanent magnets and converting it into a rotational motion of another member. Are known.

  For example, Patent Document 1 discloses a magnetic force driving apparatus having a structure in which a piston magnet 301, a fixed magnet 302, a connecting rod 303, a crankshaft 304, and a coil spring 305 are housed in a cylinder 300 as shown in FIG. . In this magnetic force driving apparatus, a piston magnet 301 and a crankshaft 304 are connected to both sides of a connecting rod 303, and fixed magnets 302 and 302 are placed on both sides of a top dead center and a bottom dead center so as to repel the piston magnet 301.

  As described above, conventionally, a power device has been known in which a piston magnet is reciprocated in a cylinder by utilizing the repulsive force or attractive force of the magnet, and the reciprocating motion is converted into the rotational motion of the crankshaft. .

  By the way, in order to obtain an effective rotational motion from this type of power unit, the rotational motion of the crankshaft must be a continuous motion. For this purpose, the piston magnet must be repeatedly reciprocated in the cylinder.

  However, the power units disclosed in the above-mentioned patent documents have the following problems.

  First, in the case of the power unit disclosed in Patent Document 1, since the piston magnet 301, the connecting rod 303, and the crankshaft 304 are all contained in the cylinder 300, the repulsive force between the piston magnet 301 and the fixed magnet 302 is increased. It was impossible to make the same action from both the dead center side and the bottom dead center side. Therefore, even if the piston magnet 301 receives the repulsive force of the fixed magnet 302 on the top dead center side and moves to the bottom dead center side, the piston magnet 301 receives the same repulsive force and returns to the top dead center side. There was no. Therefore, since the piston magnet 301 does not reciprocate, it is impossible to obtain continuous rotational power.

  Further, in the case of the power unit disclosed in Patent Document 2, the disk-shaped magnet 403 is formed by combining two semi-disk-shaped magnets 403a and 403b as shown in FIG. 25 (b). The semicircular magnets 403a and 403b have different polarities arranged on the same surface of the disc magnet 403. Then, by rotating the disk-shaped magnet 403, the repulsive force and the attractive force are alternately applied to try to repeat moving away and approaching the piston magnet 401.

  However, for example, even when a repulsive force acts on the piston magnet 401 from one semicircular magnet 403a, an attractive force acts on the piston magnet 401 from the other semicircular magnet 403b. Both repulsive force and attractive force act on 401 simultaneously. When the piston magnet 401 is moved away from the disc magnet 403 by the repulsive force, the distance between the piston magnet 401 and the disc magnet 403 is widened. Therefore, to return the piston magnet 401 to the original position, the attractive force is repelled. It must be stronger than power.

  However, in this case, in order to move the piston magnet 401 away, a repulsive force that can overcome the attractive force is required. Eventually, since the piston magnet 401 cannot be reciprocated by the rotation of the disc-shaped magnet 403, it is impossible to obtain continuous rotational power.

  Further, the power transmission mechanism disclosed in Patent Document 3 changes the polarity of magnets acting on the piston magnets 501 and 501 by alternately bringing the magnets 503 and 503 fixed to the rotating plate 504 closer to the piston magnets 501 and 501. As a result, the repulsive force and the attractive force are to be applied alternately to the piston magnets 501 and 501.

  However, even with this power transmission mechanism, in order to return the piston magnets 501 and 501 once moved away to their original positions, an attractive force stronger than the repulsive force must be applied. Moreover, when one piston magnet 501 is attracted by one magnet 503, the other magnet 503 having a different polarity tries to move the piston magnet 501 away. May antagonize. For this reason, it is difficult to continue the reciprocating motion of the piston magnets 501 and 501.

  On the other hand, Patent Document 4 discloses an apparatus that attempts to move a piston magnet away or close by repeating pinching and pulling of an iron plate between a piston magnet and a fixed magnet facing the same poles. It had been.

  However, when an iron plate is sandwiched between the piston magnet and the fixed magnet, the iron plate is attracted by both the piston magnet and the fixed magnet, and thus it is difficult to pull out the iron plate. In addition, since the iron plate is a ferromagnetic material, the magnetic force cannot be interrupted even if the iron plate is sandwiched between the piston magnet and the fixed magnet. With this, the piston magnet cannot be reciprocated.

  And since the mutually opposing surface (facing surface) of a piston magnet and a fixed magnet was set in parallel, the following subjects were not solved.

  In general, the lines of magnetic force emitted from the permanent magnet have a loop shape as shown in FIG. Therefore, as shown in FIG. 28, if the opposing surfaces 601 a and 602 a of the same polarity (N pole in FIG. 28) of the fixed magnet 601 and the piston magnet 602 face each other in parallel, the X direction shown in FIG. A repulsive force having the same magnitude acts in the Y direction. Since the piston magnet 602 is connected to a rotating crankshaft, when the piston magnet 602 leaves the position closest to the fixed magnet 601, the opposing surface 602a moves so as to move very slightly along the opposing surface 601a.

  When the opposing surface 601a and the opposing surface 602a approach each other in parallel, the repulsive force acts in a direction in which both the fixed magnet 601 and the piston magnet 602 are moved away along the central axis direction, but the opposing surface 602a. Are unlikely to act in a direction that moves in parallel along the facing surface 601a. Therefore, since the repulsive force does not act effectively on the movement of the piston magnet 602 to move away from the fixed magnet 601, it is difficult to continue the reciprocating movement.

  As described above, the conventional power device described above has a problem that continuous revolving power cannot be obtained because the reciprocating motion of the piston magnet cannot be obtained.

  The present invention has been made in order to solve the above-described problems. The reciprocating motion of the piston magnet is surely obtained and the continuity thereof is enhanced, thereby obtaining continuous rotational power. An object of the present invention is to provide a rotational power generation device and a power generation device that generates electric power using the rotational power.

In order to solve the above-described problems, the present invention provides a first piston magnet member and a first piston magnet member arranged so that the polarities of the magnetic poles on the top dead center side are equal and the top pole surface on the top dead center side faces the same direction.

  Furthermore, in the case of the rotational power generation device, the demagnetizing member has a rotating shaft that rotates the demagnetizing rotating plate around its center, and a bevel gear that meshes with the tip of the rotating shaft and the crankshaft. The bevel gear is formed so that the first and second piston magnet members reciprocate once inside the first and second guide members when the demagnetizing rotating plate makes one rotation around the rotation axis.

FIG. 8 is a partially omitted perspective view showing the first guide member 50, the first piston magnet member 60, and the first fixed magnet member 70. FIG. 9 is a side view of the engine unit 10 on the first piston magnet member 60 side viewed from the direction intersecting the crankshaft 11.

  In the rotational power generation device 100, the repulsive force (hereinafter also referred to as “first repulsive force”) of the first piston magnet member 60 and the first fixed magnet member 70 and the second piston magnet member 61 and the second The repulsive force of the fixed magnet member 71 (hereinafter also referred to as “second repulsive force”) is reduced by the demagnetizing rotating plate 32 so as to have different magnitudes, while the first and second piston magnet members 60, 61 is made to approach the first and second fixed magnet members 70 and 71 alternately.

The permanent magnet 64 is a substantially rectangular parallelepiped magnet having a size that fits into the holding case 63 without a gap, and is a neodymium magnet having a very large magnetic force, for example. In the present embodiment, the permanent magnet 64 is housed in the holding case 63 so that the polarity of the top dead center side surface (upper pole surface 60a) becomes N pole. The permanent magnet 64 of the second piston magnet member 61 is also housed in the holding case 63 such that the polarity of the top dead center side surface (upper pole face 61a) is N pole.

  In both the first and second piston magnet members 60 and 61, a connection portion 65 is formed on the crankshaft 11 side of the holding case 63. The first and second connecting rods 80 and 81 are rotatably connected to the respective connection portions 65.

  As shown in detail in FIGS. 8 and 9, the first fixed magnet member 70 (the second fixed magnet member 71 is not shown in FIGS. 8 and 9) is also shown in detail in FIGS. 8 and 9. And have. The holding case 73 for fixing is a member having the same size and shape as the holding case 63. The permanent magnet 74 is a substantially rectangular parallelepiped magnet having a size that fits into the fixing holding case 73 without a gap, and is, for example, a neodymium magnet similar to the permanent magnet 64. The permanent magnet 74 has a holding case 73 for fixing so that the surface (fixed pole surface 70a) having the same polarity (N pole in this embodiment) as the polarity of the upper pole surface 60a faces the upper pole surface 60a. It is stored in. The permanent magnet 74 of the second fixed magnet member 71 is also housed in the fixed holding case 73 so that the fixed pole surface 71a becomes the N pole.

  Both the permanent magnet 74 and the permanent magnet 64 described above are magnets having a strong magnetic force, and the upper pole surfaces 60a and 61a and the fixed pole faces 70a and 71a having the same polarity are opposed to each other. Both the power and the second repulsive force are powerful.

  The first fixed magnet member 70 (the second fixed magnet member 71 is not shown in FIG. 9 but is also the same) is fixed to the lid 6 using four adjustment members 75. That is, the screw portion 75 a of the adjustment member 75 is inserted into the lid portion 6 from the outside and screwed into the holding case 73 for fixing. By changing the screwing state of the screw portion 75a, the inclination of the first fixed magnet member 70 with respect to the lid portion 6 changes, and the inclination of the fixed pole surface 70a changes.

  Further, in the fixed pole surface 70a and the upper pole surface 60a, the rearmost side along the rotation direction fa of the crankshaft 11 (also referred to as “rear part” in the present embodiment, which is indicated by reference numeral 79 in FIG. The interval D2 (the interval between the last portions 79 is also referred to as the last interval) is made wider than the interval D1 between the other portions (the same applies to the fixed pole surface 71a and the upper pole surface 61a).

  Thus, the rotational power generation device 100 has a repulsive force non-uniform structure in which the repulsive force between the upper pole surface 60a and the fixed pole surface 70a in the rearmost portion 79 is smaller than the repulsive force of other portions. Yes. The angle formed between the fixed pole surface 70a and the upper pole surface 60a is set to a predetermined inclination angle α.

  The first and second connecting rods 80 and 81 are connected to the bottom dead center side (to the connection portion 65) of the first and second piston magnet members 60 and 61 as described above. Both the first and second connecting rods 80 and 81 are connected to the crankshaft 11. First and second connecting rods 80 and 81 are connected to the first and second crank portions 11a and 11c of the crankshaft 11, respectively.

  Next, the demagnetizing member 30 will be described. The demagnetizing member 30 is formed using a nonmagnetic material such as aluminum. The demagnetizing member 30 includes a rotating shaft 31, a demagnetizing rotating plate 32, and a bevel gear 33, as shown in FIGS. A demagnetizing rotating plate 32 is fixed to the upper end portion of the rotating shaft 31, and a bevel gear 33 is fixed to the lower end portion. The rotating shaft 31 is inserted through a support portion 8b fixed to the intermediate wall portion 8a via a bearing. 5 assumes a center line passing through the center of the demagnetizing rotating plate 32.

  The demagnetizing rotating plate 32 has a thickness that fits between the upper pole faces 60a and 61a and the fixed pole faces 70a and 71a, and has a diameter that can cover both the upper pole faces 60a and 61a. By providing, it is a disk of a magnitude | size facing the whole upper pole surface 60a, 61a. The demagnetizing rotating plate 32 has a demagnetizing magnet portion 38 and a non-magnetic portion 39 on both the lower surface 32a facing the upper pole surfaces 60a and 61a and the upper surface 32b facing the fixed pole surfaces 70a and 71a. ing.

  The demagnetizing magnet portion 38 and the non-magnetic portion 39 are formed in a circular band shape (also referred to as a donut shape) centering on the rotation shaft 31. The demagnetizing magnet portion 38 is assigned to a region somewhat larger than the semicircle-corresponding portion of the circular belt-like portion, and the non-magnetic portion 39 is assigned to a region somewhat smaller than the remaining semicircle-corresponding portion. In this way, the non-magnetic portion 39 is reduced so that only one of the first and second piston magnet members 60 and 61 faces and not both the first and second piston magnet members 60 and 61 face each other at the same time. A magnetic rotating plate 32 is formed.

  Further, the demagnetizing magnet portion 38 and the non-magnetic portion 39 are disposed at positions corresponding to the upper pole surfaces 60a and 61a of the demagnetizing rotating plate 32, and the radial width w38 is the same as that of the upper pole surfaces 60a and 61a. The size is approximately the same as the width or somewhat larger than the width.

  Further, the demagnetizing magnet portion 38 is weaker than the magnetic poles on the upper pole surfaces 60a and 61a side of the first and second piston magnet members 60 and 61, and has a magnetic force having a polarity different from that of the upper pole surfaces 60a and 61a. . In the present embodiment, the polarity of the demagnetizing magnet unit 38 is set to the S pole. The magnetic force of the demagnetizing magnet unit 38 is weaker than that of the permanent magnets 64 and 74.

  The demagnetizing magnet portion 38 includes a strong demagnetizing portion 35 having the strongest magnetic force, a weak demagnetizing portion 36 having the weakest magnetic force, and a medium demagnetizing force having an intermediate magnetic force between the strong demagnetizing portion 35 and the weak demagnetizing portion 36. And a magnetic part 37. In the demagnetizing magnet section 38, the strong demagnetizing section 35, the medium demagnetizing section 37, and the weak demagnetizing section 36 are arranged clockwise in this order along the circumferential direction.

  Therefore, when the demagnetizing rotating plate 32 rotates clockwise, the weakly demagnetized portion 36, the medium demagnetized portion 37, and the strong demagnetized portion 35 are formed on the upper pole surfaces 60a and 61a as shown in FIG. Sequentially appear, the magnetic force of the demagnetizing magnet portion 38 changes so as to gradually increase along the circumferential direction. The demagnetizing magnet unit 38 has a magnetic force change structure in which the magnetic force changes in this way. Further, a non-magnetic part 39 appears after the demagnetizing magnet part 38, and then a weak demagnetizing part 36 appears.

  Further, the non-magnetic part 39 is a part of a circular belt-like part along the circumferential direction of the demagnetizing rotating plate 32 and corresponds to a part between the strong demagnetizing part 35 and the weak demagnetizing part 36. The non-magnetic part 39 is a part having no magnetic force.

  A bevel gear 11 d is engaged with the bevel gear 33. Therefore, the rotating shaft 31 rotates according to the rotation of the crankshaft 11, and the demagnetizing rotating plate 32 rotates. As will be described in detail later, the bevel gear 33 and the bevel gear 11d rotate the crankshaft 11 once when the demagnetizing rotating plate 32 makes one rotation around the rotating shaft 31, thereby the first and second pistons. Magnet members 60 and 61 are formed so as to reciprocate once inside the first and second guide members 50 and 51.

  Moreover, the bevel gear 33 is engaged with the bevel gear 11d so that the rotational power generation device 100 has the following structure. Therefore, in the rotational power generation device 100, when the bevel gear 33 is engaged with the bevel gear 11d, each position is adjusted. The structure is that when the first piston magnet member 60 reaches the top dead center, the second piston magnet member 61 reaches the bottom dead center, and immediately after that, in the first gap, In this structure, the demagnetizing magnet portion 38 is switched to the non-magnetic portion 39 and the weak demagnetizing portion 36 is disposed in the second gap (hereinafter, this structure is also referred to as “basic structure”).

  The first gap is a portion between the first piston magnet member 60 and the first fixed magnet member 70, and the second gap is the second piston magnet member 61 and the second piston magnet member 61. It is a portion between the fixed magnet member 71.

(Operation details of the rotary power generator)
Next, with reference to FIGS. 10 to 20, the operation content of the rotational power generation device 100 will be described.

  Here, FIG. 10A is a diagram schematically showing the first piston magnet member 60, the first fixed magnet member 70, and the demagnetizing rotating plate 32 immediately after reaching the bottom dead center. b) is a diagram schematically showing a main part of the demagnetizing rotating plate 32 at that time. FIGS. 11A to 13A schematically illustrate the first piston magnet member 60, the first fixed magnet member 70, and the demagnetizing rotating plate 32 that follow FIGS. 10A to 12A, respectively. FIGS. 11 (b) to 13 (b) are schematic views showing the main part of the demagnetizing rotating plate 32 following FIGS. 10 (b) to 12 (b).

  FIG. 14A schematically shows the first piston magnet member 60, the first fixed magnet member 70, and the demagnetizing rotating plate 32 following FIG. 13A, and FIG. It is the figure which showed typically the principal part of the demagnetizing rotating plate 32 at the time. FIG. 15A is an enlarged view of a portion 25a surrounded by a dotted line in FIG. 13A, and FIG. 15B is an enlarged view of a portion 25b surrounded by a dotted line in FIG.

  Since the rotational power generation device 100 has the above configuration, the following operation is performed. In order to operate the rotational power generation device 100, first, a power switch (not shown) is turned on to operate the starter motor 14a. When the starter motor 14a is operated by the electric power stored in the battery 13b, the power is transmitted to the crankshaft 11 via the belt 16a, and the crankshaft 11 rotates in the direction of the arrow e11 shown in FIG. Accordingly, the first and second piston magnet members 60 and 61 move inside the first and second guide members 50 and 51 via the first and second connecting rods 80 and 81, respectively. Thereby, the initial operation is completed.

  Since the starter motor 14a is provided with an overrunning clutch (not shown), the power of the crankshaft 11 is not transmitted to the starter motor 14a. The rotational power generation device 100 uses the power of the starter motor 14a in the initial operation described above, but uses the power of the starter motor 14a periodically (for example, in units of several seconds) even after the initial operation is completed. The power of the starter motor 14a is also used when the rotation speed of the crankshaft 11 becomes smaller than the set rotation speed. In these cases, when the timer relay 13c is operated, the starter motor 14a is operated by receiving power from the battery 13b, and the power is transmitted to the crankshaft 11. The operation after the initial operation is completed is as follows.

  Here, as shown in FIG. 10A, consider immediately after the first piston magnet member 60 reaches bottom dead center. At this time, since the crankshaft 11 tends to continue to rotate due to inertia, the first piston magnet member 60 tends to approach the first fixed magnet member 70.

  At this time, when the first piston magnet member 60 reaches bottom dead center, the demagnetizing magnet portion 38 of the demagnetizing rotating plate 32 appears in the first gap. As shown in FIG. 10B, the weakly demagnetized portion 36 is disposed in the first gap immediately after the first piston magnet member 60 reaches bottom dead center. Since the weak demagnetization part 36 is different in polarity from the upper pole face 60a and the fixed pole face 70a, the weak demagnetization part 36 has a demagnetizing action that weakens the magnetic force output from the upper pole face 60a and the fixed pole face 70a. Demonstrate. By this demagnetizing action, the first repulsive force that is constantly acting between the first piston magnet member 60 and the first fixed magnet member 70 is reduced by the amount of the attractive force f10. Then, the 1st piston magnet member 60 becomes easy to advance.

  Next, as shown in FIG. 11A, as the first piston magnet member 60 moves forward, as shown in FIG. 11B, the weak demagnetizing portion 36 of the demagnetizing rotating plate 32 is moved. The medium demagnetization part 37 appears, and the medium demagnetization part 37 appears in the first gap. As the first piston magnet member 60 moves forward, the first repulsive force becomes stronger. However, when the weak demagnetizing portion 36 is switched to the middle demagnetizing portion 37, the first repulsive force is greater than the attractive force f10. It is reduced by the large suction force f11. Therefore, the first piston magnet member 60 continues to advance.

  Subsequently, as shown in FIG. 12A, as the first piston magnet member 60 moves forward, as shown in FIG. The strong demagnetization part 35 appears in the first gap after switching to the strong demagnetization part 35. Therefore, since the first repulsive force is reduced by the amount of the attractive force f12 that is larger than the attractive force f11, the first piston magnet member 60 continues to advance.

  Subsequently, the first piston magnet member 60 moves forward. At this time, since the strong demagnetizing portion 35 is disposed in the first gap, the first repulsive force is reduced by the amount of the attractive force f12. When the first piston magnet member 60 continues to advance, the first piston magnet member 60 reaches top dead center as shown in FIG. Also at this time, as shown in FIG. 13B, the strong demagnetizing portion 35 is disposed in the first gap.

  Then, as shown in FIG. 14A, immediately after the first piston magnet member 60 reaches the top dead center, as shown in FIG. 14B, the demagnetizing rotating plate 32 is formed in the first gap. The strong demagnetization part 35 is switched to the magneticless part 39, and the magneticless part 39 is arranged in the first gap in place of the strong demagnetization part 35.

  Then, when the first repulsive force has been reduced by the demagnetizing action of the strong demagnetizing part 35 until then, the strong demagnetizing part 35 is switched to the non-magnetic part 39, so that the reducing action against the first repulsive force is achieved. Suddenly disappears. Therefore, as shown in FIG. 14A, the strong first repulsive force f14 is suddenly restored to the first piston magnet member 60 and the first fixed magnet member 70. By the first repulsive force f14, the first piston magnet member 60 is strongly pushed down immediately after reaching the top dead center, and retreats vigorously in the direction indicated by f60.

  When the first piston magnet member 60 reaches the top dead center, the first connecting rod 80 extends in the vertical direction, so that the first piston magnet member is applied even when the first repulsive force is applied. 60 is difficult to retreat. In order to make the first piston magnet member 60 easy to move backward, it is desirable that the strong demagnetizing portion 35 is switched to the non-magnetic portion 39 immediately after the first piston magnet member 60 reaches the top dead center.

  The above description relates to an operation (also referred to as a half-process operation) from immediately after the first piston magnet member 60 reaches bottom dead center to just after reaching top dead center. The operation | movement of the half process regarding the 1st piston magnet member 60 is parallel to the operation | movement which the 2nd piston magnet member 61 reverse | retreats.

  In the rotational power generation device 100, the first piston magnet member 60 and the first fixed magnet member 70, and the second piston magnet member 61 and the second fixed magnet member 71 perform the operation of the half process alternately. . Next, this point will be described with reference to FIGS.

  Here, FIG. 16A is a diagram schematically showing the first and second piston magnet members 60 and 61 and the crankshaft 11 immediately after reaching the top dead center and the bottom dead center, respectively. b) is a diagram schematically showing the demagnetizing rotating plate 32 at that time. FIGS. 17 (a) to 20 (a) schematically show the first and second piston magnet members 60 and 61 and the crankshaft 11 following FIGS. 16 (a) to 19 (a), respectively. FIGS. 17B to 20B are diagrams schematically showing the demagnetizing rotating plate 32 following FIGS. 16B to 19B, respectively.

  As shown in FIG. 16A, consider immediately after the first and second piston magnet members 60 and 61 reach the top dead center and the bottom dead center, respectively. In this case, the bevel gear 33 is meshed with the bevel gear 11d so that the rotational power generation device 100 has the basic structure described above. Therefore, in the first gap, the demagnetizing magnet portion 38 (strong demagnetizing portion 35) of the demagnetizing rotating plate 32 is switched to the nonmagnetic portion 39, and the weak demagnetizing portion 36 is disposed in the second gap. . Accordingly, the first piston magnet member 60 moves back in the direction indicated by f60, and the second piston magnet member 61 moves forward by reducing the second repulsive force.

  Subsequently, as shown in FIG. 17A, the first piston magnet member 60 moves backward by reducing the second repulsive force at the same time as the first piston magnet member 60 moves backward vigorously. If this continues, as shown in FIG. 18A, the first and second crank portions 11a, 11c of the crankshaft 11 become parallel.

  At this time, as shown in FIG. 18B, at the same time as the non-magnetic part 39 is arranged in the first gap, the strong demagnetizing part 35 is arranged in the second gap. Therefore, the crankshaft 11 continues to rotate as if the second piston magnet member 61 moves forward while the first piston magnet member 60 moves backward. And since the demagnetizing rotating plate 32 maintains the same state, this state continues thereafter as shown in FIG.

  Then, this time, as shown in FIG. 20A, the first piston magnet member 60 reaches the bottom dead center, and the second piston magnet member 61 reaches the top dead center. Therefore, the first and second piston magnet members 60 and 61 continue the operation after exchanging the operations of the half steps that have been executed.

  Thus, the 1st, 2nd piston magnet members 60 and 61 continue repeating the operation | movement of a half process alternately. Therefore, in the rotational power generation device 100, the reciprocating motion of the first and second piston magnet members 60 and 61 can be realized, and the reciprocating motion is made continuous by using the power of the starter motor 14a. Continuity can be increased. The rotational speed of the crankshaft 11 is reduced by the influence of the frictional force and the like when the crankshaft 11 and the first and second piston magnet members 60 and 61 move. Then, the reciprocating motion of the first and second piston magnet members 60 and 61 does not continue. Therefore, the rotational power generation device 100 uses the power of the starter motor 14a as described above.

  When the first and second piston magnet members 60 and 61 continue to reciprocate, the rotational motion of the crankshaft 11 continues via the first and second connecting rods 80 and 81. Then, the rotational power of the crankshaft 11 is transmitted to the motor generators 15a and 15b via the belt 16b, and the coils of the motor generators 15a and 15b rotate. Electric power is obtained by rotating the coils of the motor generators 15a and 15b. This electric power can be taken out using an output cord (not shown).

(Operational effect of the rotational power generator)
As described above, the first and second piston magnet members 60 and 61 and the first fixed magnet members 70 and 71 have the same polarity of the magnetic poles on the upper pole surfaces 60a and 61a and the fixed pole surfaces 70a and 71a. Therefore, the first and second piston magnet members 60 and 61 and the first and second fixed magnet members 70 and 71 attempt to retract the first and second piston magnet members 60 and 61, respectively. The first and second repulsive forces are always acting.

  However, the demagnetizing rotating plate 32 is disposed in both the first gap and the second gap. A demagnetizing magnet portion 38 is formed on the demagnetizing rotating plate 32, and the polarity of the magnetic force in the demagnetizing magnet portion 38 is different from the polarity of the magnetic poles on the upper pole surfaces 60a and 61a and the fixed pole surfaces 70a and 71a. .

  Therefore, some of the lines of magnetic force output from the first and second piston magnet members 60 and 61 and the first and second fixed magnet members 70 and 71 are absorbed by the demagnetizing magnet unit 38. As a result, the lines of magnetic force that contribute to the repulsion of the upper pole surfaces 60a and 61a and the fixed pole surfaces 70a and 71a are reduced, so that the magnetic force that causes the first and second repulsive forces is reduced. Since the demagnetizing magnet portion 38 exhibits such a demagnetizing action for reducing the magnetic force, the first and second repulsive forces are reduced by the demagnetizing magnet portion 38 appearing in the first and second gaps.

  In the rotational power generation device 100, the demagnetizing rotation is performed so that the demagnetizing magnet portion 38 and the nonmagnetic portion 39 are adjacent to each other, and the nonmagnetic portion 39 is disposed only in one of the first and second gaps. A plate 32 is formed. When the demagnetizing rotating plate 32 is rotated, the non-magnetic portion 39 is disposed only in one of the first and second gaps, and both the first and second gaps are not simultaneously disposed.

  Therefore, it does not act on the first and second piston magnet members 60 and 61 at the same timing without reducing the first and second repulsive forces. Assuming that the first and second piston magnet members 60 and 61 act on the first and second piston magnet members 60 and 61 at the same timing without reducing the first and second repulsive forces, both the first and second piston magnet members 60 and 61 Since it tries to move backward, there is a possibility that the reciprocating motion cannot be obtained. However, in the rotational power generation device 100, there is no fear thereof.

  Since at least one of the first and second repulsive forces is demagnetized by the demagnetizing magnet portion 38, the second piston magnet member 61 can easily move forward when the first piston magnet member 60 is retracted. On the contrary, when the second piston magnet member 61 is moved backward, the first piston magnet member 60 is easily moved forward. The first and second piston magnet members 60 and 61 are always subjected to the first and second repulsive forces, respectively, but the first and second repulsive forces act at the same timing and the same magnitude. There is nothing. Therefore, the first and second piston magnet members 60 and 61 can be retracted alternately. Further, because of the inertia of the crankshaft 11, after one of the first and second piston magnet members 60, 61 is retracted, the transition is smoothly made to the other. Therefore, the first and second piston magnet members 60 and 61 are continuously retracted.

  By the way, in the prior art, for example, as in the power transmission mechanism disclosed in Patent Document 3, the different polarities of the two magnets are alternately approached to the two piston magnets, and the repulsive force and the attractive force are applied alternately. I was trying to let them.

  However, once the piston magnet is moved away by the repulsive force, it is almost impossible to return it to the original position by the attractive force even if a very strong magnet is used. That is, the reciprocating motion of the piston magnet cannot be obtained by causing the repulsive force and the attractive force to act alternately on the piston magnet.

  In this respect, the rotational power generation device 100 is based on the fact that only the repulsive force is applied to the first and second piston magnet members 60 and 61, and the reciprocating force is applied to the first and second piston magnet members 60 and 61 in the same way. Considering that no movement can be obtained, the above structure is adopted.

  That is, in the rotational power generation device 100, while retreating one of the first and second piston magnet members 60 and 61, reciprocating motion is realized by supporting the other forward by reducing the repulsive force. The repulsive force is alternately reduced, and the power of the starter motor 14a is used to make the reciprocating motion continuous. Note that, depending on the shape of the demagnetizing magnet portion 38, there is a possibility that both the first and second repulsive forces may have a reducing effect. In that case, the magnetic force of the demagnetizing magnet portion 38 disposed in each of the first and second gaps may be different (for example, one is a strong demagnetizing portion and the other is a weak demagnetizing portion). ).

  The demagnetizing rotating plate 32 is effective in reducing the repulsive force alternately. The demagnetizing rotating plate 32 has a size that covers both the upper pole surfaces 60a, 61a of both the first and second piston magnet members 60, 61, and has a demagnetizing magnet portion 38 and a non-magnetic portion 39. doing.

  Therefore, by rotating this, repulsive force reduction for the first and second piston magnet members 60 and 61 can be performed alternately. Therefore, the rotational power generation device 100 can obtain the reciprocating motion of the first and second piston magnet members 60 and 61, and can continuously perform the reciprocating motion by using the power of the starter motor 14a. Continuity can be increased. Thereby, the continuous rotational power which the crankshaft 11 rotates continuously can be obtained.

  Further, since the magnetic force of the demagnetizing magnet portion 38 is weaker than the magnetic force of the magnetic poles of the first and second piston magnet members 60 and 61, even if the magnetic field lines are absorbed by the demagnetizing magnet portion 38, the first and second The resilience can be preserved.

  Further, since the demagnetizing magnet portion 38 and the non-magnetic portion 39 are formed in a circular belt shape, even if the demagnetizing rotating plate 32 is rotated, the demagnetizing magnet portion 38 and the non-magnetic portion 39 are first and first. The two gaps can be arranged with the same size.

  On the other hand, in the rotational power generation device 100, the first piston magnet member 60 and the first fixed magnet member 70, and the second piston magnet member 61 and the second fixed magnet member 71 have a repulsive force non-uniform structure. doing.

  When the crankshaft 11 rotates, for example, immediately after the first piston magnet member 60 reaches top dead center, the first crank portion 11a rotates the crankshaft 11 as shown in FIG. It tilts forward along the direction fa. The first repulsive force always acts on the first piston magnet member 60. Therefore, the first repulsive force tends to retract the first piston magnet member 60 even when the first piston magnet member 60 reaches the top dead center and the first crank portion 11a is vertically cut. . However, even if a repulsive force is applied when the first crank portion 11a is vertically upright, the crankshaft 11 is difficult to rotate because a moment cannot be obtained. Therefore, the first piston magnet member 60 moves backward. Hateful.

  However, if the repulsive force non-uniform structure is used, the repulsive force in the other part than the rearmost part 79 becomes larger, so the first piston magnet member 60 can rotate in the direction of rotation of the crankshaft 11 even when it reaches top dead center. The front side along the side is easier to retreat. Therefore, if the crankshaft 11 continues to rotate with inertia and the first crank portion 11a is tilted forward, the first piston magnet member 60 is likely to retreat, and the repulsive force reducing action disappears at this point. In combination, the first piston magnet member 60 is more easily retracted. Therefore, the rotational power generation device 100 can further increase the continuity of the reciprocating motion.

  Furthermore, since the demagnetizing magnet portion 38 has a magnetic force change structure, when the demagnetizing rotating plate 32 rotates clockwise, the repulsive force reducing action is improved stepwise. Then, the 1st, 2nd repulsive force which improves with advance of the 1st, 2nd piston magnet members 60 and 61 can be reduced in steps. Therefore, one retreat by the first and second piston magnet members 60 and 61 and the other advance are ensured, and the reciprocating motion can be made more reliable.

  When the demagnetizing rotating plate 32 makes one rotation, the bevel gear 33, so that the first and second piston magnet members 60, 61 reciprocate once inside the first and second guide members 50, 51, respectively. 11d is formed. Therefore, one rotation of the demagnetizing rotating plate 32 is associated with a half process of the first piston magnet member 60 and a subsequent half process of the second piston magnet member 61. By rotating the demagnetizing rotating plate 32 once, the first and second piston magnet members 60 and 61 can be retracted alternately.

  On the other hand, in the rotational power generation device 100, a gap 53 is formed in the first and second guide members 50 and 51. As the first and second piston magnet members 60 and 61 reciprocate, frictional heat is generated by the friction between the first and second piston magnet members 60 and 61 and the first and second guide members 50 and 51. It can be discharged to the outside of the first and second guide members 50 and 51.

  In general, it is known that the spontaneous magnetization of a ferromagnetic material decreases exponentially with increasing temperature, and disappears when the magnetism of the ferromagnetic material exceeds the Curie temperature. Therefore, when frictional heat is generated and accumulated in the first and second piston magnet members 60 and 61, the magnetic force of the permanent magnets 64 and 74 may be reduced. Then, the first and second repulsive forces are weakened, and the first and second piston magnet members 60 and 61 may not be able to repeat the reciprocating motion.

  In particular, when the piston magnet is sealed in the cylinder as in the prior art, the frictional heat associated with the friction between the piston magnet and the cylinder tends to be trapped in the cylinder, and the temperature of the piston magnet increases accordingly. It's easy to do.

  However, in the rotational power generation device 100, since the gap portion 53 is formed in the first and second guide members 50 and 51, heat such as frictional heat is hardly accumulated. Therefore, the magnetic force of the permanent magnets 64 and 74 can be prevented from being lowered, and the reciprocating motion of the first and second piston magnet members 60 and 61 can be continued.

  In the rotational power generation device 100, the inclination angle of the fixed pole surfaces 70 a and 71 a in the first and second fixed magnet members 70 and 71 can be adjusted by the adjustment member 75. Therefore, even if the inclination angle of the fixed pole surfaces 70a and 71a changes due to vibration during operation, the inclination angle can be adjusted.

  The rotational power generation device 100 can generate electric power by transmitting the continuous rotational power of the crankshaft 11 described above to the internal motor generators 15a and 15 and can therefore be used as a power generation device. . Of course, the rotational power can be used for other purposes.

(Modification 1)
FIG. 21A is a partially omitted perspective view showing the guide member 54 according to the first modification. The guide member 54 has two holding members 55 having a substantially C-shaped cross section. Each holding member 55 is spaced apart so that a gap 55a is formed. The guide member 54 can also guide the first and second piston magnet members 60 and 61 like the first and second guide members 50 and 51, and can release frictional heat to the outside of the guide member 54. Can do.

  FIG. 21B is a plan view of the demagnetizing member 40 according to the first modification. The demagnetizing member 40 is different from the demagnetizing member 30 in that it has a demagnetizing rotating plate 42 instead of the demagnetizing rotating plate 32. The demagnetizing rotating plate 42 is different from the demagnetizing rotating plate 32 in that it has a demagnetizing magnet portion 48 instead of the demagnetizing magnet portion 38. The demagnetizing magnet part 48 is different from the demagnetizing magnet part 38 in that it has a strong demagnetization part 45 and a weak demagnetization part 46 and does not have an intermediate demagnetization part. The strong demagnetization part 45 has the same magnetic force as the strong demagnetization part 35, but is larger than the strong demagnetization part 35. The weak demagnetization part 46 is the same as the weak demagnetization part 36. Similar to the demagnetizing magnet unit 38, the demagnetizing magnet unit 48 has a magnetic force change structure that changes so that the magnetic force gradually increases along the circumferential direction.

  In addition, in the demagnetizing rotating plate 32, a portion where no magnetic force exists in the circular belt-shaped portion centering on the rotating shaft 31 is defined as a non-magnetic portion 39. In this case, the portion made of a nonmagnetic material becomes the non-magnetic portion 39, but the circular strip-shaped portion of the demagnetizing rotating plate 32 is cut out to form a circular strip-shaped hole portion, and the hole portion is formed into the non-magnetic portion. It may be 39.

  Further, the demagnetizing rotating plate 32 may be a demagnetizing rotating plate 72 shown in FIG. The demagnetizing rotating plate 32 may be a demagnetizing rotating plate 82 shown in FIG. The demagnetizing rotating plate 72 is a substantially semicircular plate material in which a fan-shaped portion including the nonmagnetic portion 39 is cut out.

  The demagnetizing rotating plate 82 has a plurality of bone portions 82a extending radially from the central portion to which the rotation shaft 31 is fixed, and the demagnetizing magnet portion 38 and the non-magnetic portion 39 are formed in the plurality of bone portions 82a. Is formed. Further, a gap 82b is formed between the adjacent bone parts 82a.

  The demagnetizing rotating plate 82 includes a portion that is not formed in a plate shape only of the plurality of bone portions 82a, but the portion in which the demagnetizing magnet portion 38 is formed is formed in a plate shape. In the present embodiment, not only a member that is formed in a plate shape like the demagnetization rotating plate 32 but also a part that is formed in a plate shape like the demagnetizing rotation plate 82 is partially Only the member is a demagnetizing rotating plate.

  The demagnetizing rotating plates 72 and 82 have a shape in which a portion where the demagnetizing magnet portion 38 is formed faces at least one of the upper pole surfaces 60a and 61a. In addition, since the demagnetizing rotating plates 72 and 82 are lighter than the demagnetizing rotating plate 32, they can be rotated with less energy than the demagnetizing rotating plate 32.

Then, with reference to FIG. 22, the rotational power generation apparatus 200 which concerns on the modification 2 is demonstrated. The rotational power generation device 200 is different from the rotational power generation device 100 described above in that it includes an engine unit 110, motor generators 15c and 15d, and a belt 16c.

  In the rotational power generation device 200, both the engine unit 10 and the engine unit 110 have the crankshaft 11, but the crankshaft 11 in the engine unit 10 and the crankshaft 11 in the engine unit 110 are both provided. One common crankshaft 11A is provided. Moreover, in both engine parts 10 and 110, the phase of the 1st, 2nd piston magnet members 60 and 61 is common.

There is no difference in that. Moreover, the motor generators 15c and 15d have the same configuration as the motor generators 15a and 15b described above, respectively. The belt 16c has a configuration common to the belt 16b.

  In the rotational power generation device 201 as well, as with the rotational power generation device 200, the crankshafts 11 in the two engine units 10 and 120 are a common crankshaft 11A that is common to both. Moreover, the phase of the 1st piston magnet member 60 is common in both the engine parts 10 and 110. FIG.

  In the rotational power generation device 201, the reciprocating motion of the first piston magnet member 60 in the engine unit 10 and the reciprocating motion of the first piston magnet member 60 in the engine unit 120 are performed in a superimposed manner, and the reciprocating motion is superimposed. The crankshaft 11 (common crankshaft 11A) rotates by the movement. Therefore, the rotational power of the crankshaft 11 (common crankshaft 11A) can be made stronger than that of the rotational power generator 100.

Members 70 and 71 are fixed. Further, the first and second guide members 50 and 51 and the first and second piston magnet members 60 and 61 are disposed so as to face the first and second fixed magnet members 70 and 71. .
