Embodiment 1
FIG. 1 is a front view showing the overall configuration of the power generator according to Embodiment 1 of the present invention. FIG. 2 is a side view showing the overall configuration of the power generator according to Embodiment 1 of the present invention.

  As shown in FIGS. 1 and 2, the power generator according to the first embodiment generates flywheel 11, motor 21 that can freely drive flywheel 11, generator 31, and rotational force of flywheel 11. And clutch mechanisms 41 and 42 for intermittently transmitting to the machine 31. Specifically, a pedestal 2 is disposed and fixed on an installation surface 1 such as a ground surface or a floor surface at a place where the power generation device of the first embodiment is installed. The pedestal 2 has, for example, a rectangular flat plate shape. As shown in FIG. 1, the flywheel 11 and the prime mover 21 are arranged on the left side (left side in FIG. 1), and the generator 31 is arranged on the right side. Yes.

The front side of the auxiliary pedestal 3 (left side in FIG. 2) is fixed to the rear side of the pedestal 2, and the rear end portion (right end portion in FIG. 2) is fixed to the installation surface 1 via the legs 4.

  The flywheel 11 has a large-diameter disk shape (large wheel shape), and a rotary shaft 13 is passed through and fixed to the center of the flywheel 11 via a bush 12. As the flywheel 11, any flywheel such as iron, cast iron, FRP, or the like can be adopted. The rotary shaft 13 protrudes on both sides in the axial direction so as to be coaxial with the center of the flywheel 11. The rotating shaft 13 may be directly fixed to the flywheel 11 without using the bush 12. The rotating shaft 13 is attached to the pair of left and right mounts 14 and 15 so as to be rotatable. Thereby, the flywheel 11 is supported by the mounts 14 and 15 via the pair of left and right rotating shafts 13. In addition, the mounts 14 and 15 can be made of the same material as the flywheel 11, for example, iron or cast iron. A pulley 16 is coaxially fixed to one end (the left end in FIG. 1) of the rotating shaft 13 and rotates together with the rotating shaft 13. On the other hand, a pulley 16 is coaxially fixed to one end (left end in FIG. 1) of the rotating shaft 13 and rotates together with the rotating shaft 13. A case 17 is disposed between the pair of mounts 14 and 15 so as to cover the flywheel 11, the bush 12, and the rotating shaft 13, and protects them.

  The prime mover 21 can be composed of any prime mover such as an electric motor (motor), an internal combustion engine, a windmill, a water wheel, or a steam turbine. Between the pulley 22 attached to the tip of the rotating shaft (drive rotating shaft) of the prime mover 21 and the pulley 16 at the tip of the rotating shaft 13 of the flywheel 11, a connecting belt 25 is mounted so as to span the pulley of the prime mover 21. 22 and the pulley 16 at the tip of the rotary shaft 13 of the flywheel 11 are connected. The connecting belt 25 can be constituted by a flat belt, a V belt, or the like. As long as the flywheel 11 can be rotationally driven by the prime mover 21, other transmission devices can be used instead of the connecting belt 25. For example, the pulley 22 of the prime mover 21 and the pulley 16 at the tip of the rotary shaft 13 of the flywheel 11 are connected via an indirect transmission device such as a chain other than the connecting belt, or a direct transmission device such as a gear or a cam, The power of the prime mover 21 can be transmitted to the flywheel 11.

  As the generator 31, a DC generator, which can use an AC generator such as a synchronous generator or an induction generator, can also be used. The generator 31 is supported by a pair of left and right mounts 32 and 33. Further, as the clutch mechanisms 41, 42, any clutch mechanism such as a friction clutch (single plate type, multi-plate type) such as a dry clutch or a wet clutch, an electromagnetic clutch, a fluid clutch, or the like can be used. One clutch 41 is coaxially fixed to the other end of the rotating shaft 13 of the flywheel 11, and the other clutch 42 is coaxially fixed to the rotating shaft 34 of the electric motor 31. Furthermore, the clutch mechanisms 41 and 42 are covered with a cover 43 and are protected from the outside.

  On the other hand, in Embodiment 1, the generator 31 is reciprocally movable so that the generator 31 approaches or separates from the flywheel 11 by the generator moving means. That is, the generator 31 is moved so as to approach the flywheel 11 by the generator moving means and arranged at the coupling position, and the rotating shaft 34 of the generator 31 and the rotating shaft of the flywheel 11 are moved by the clutch mechanisms 41 and 42. 13, the rotational force of the flywheel 11 is transmitted to the generator 31. On the other hand, the generator 31 is moved away from the flywheel 11 by the generator moving means and disposed at the release position, and the rotating shaft 34 of the generator 31 and the rotating shaft of the flywheel 11 are moved by the clutch mechanisms 41 and 42. By releasing the connection with 13, the transmission of the rotational force of the flywheel 11 to the generator 31 is cut off. Specifically, the generator moving means includes a rail 51 and a hydraulic pump 52. The rail 51 constitutes a track or rail arranged coaxially with the rotary shaft 13 of the flywheel 11 and the rotary shaft 34 of the generator 31. Both racks 32 and 33 support the generator 31 between its upper ends, and are provided with rolling means such as wheels and sliding means so as to be smoothly reciprocated integrally along the rail 51. Via the rail 51. The hydraulic pump 52 is operatively connected to the gantry 32, 33 and drives the gantry 32, 33 to reciprocate along the rail 51. For example, the wheels are fixed to the lower ends of the gantry 32 and 33, and the generator 31 is moved along the rail 51 via the gantry 32 and 33 by being driven forward and reverse by the hydraulic pump 52 using the wheel as a driving wheel. be able to. Alternatively, the generators 31 can be moved along the rails 51 via the gantry 32 and 33 by pressing and pulling the gantry 32 and 33 via the hydraulic cylinder or the like by the hydraulic pump 52.

  The power generation apparatus according to Embodiment 1 further includes adjustment means provided so as to be close to and away from the connection belt 25. The adjusting means abuts on the connecting belt 25 in a state of approaching the connecting belt 25, and presses the connecting belt 25 in a direction intersecting the track (substantially in the thickness direction, the vertical direction, etc.). On the other hand, the adjusting means releases the pressing of the connecting belt 25 while being separated from the connecting belt 25. Specifically, the adjusting means is disposed at a predetermined position on the track of the connecting belt 25 and includes a fixed seat 61, an adjusting plate 62, and an adjusting plate driving means 65. The fixed seat 61 is fixed between the tip of the rotating shaft of the prime mover 21 (pulley 22) and the tip of the rotating shaft 13 of the flywheel 11 (pulley 16). The adjusting plate 62 is vertically fixed to the fixed seat 61 so that the adjusting plate 62 is connected to the tip of the rotating shaft of the prime mover 21 (pulley 22) and the tip of the rotating shaft 13 of the flywheel 11 (pulley 16). Arranged between. Further, the adjustment plate 62 has a pair of upper and lower insertion holes 62a through which the connecting belt 25 is inserted. The adjustment plate 62 has at least a contact position where the peripheral portion of the insertion hole 62a contacts the connection belt 25 in a state where the connection belt 25 is inserted through the pair of insertion holes 62a, and a peripheral portion of the insertion hole 62a. It is possible to move between a position separated from 25 and a separated position. In addition, a roller is provided in the peripheral part of the insertion hole 62a of the adjusting plate 62, and the connecting belt 25 is smoothly moved by pressing the connecting belt 25 through the roller at the contact position. A sliding surface or a sliding contact surface is provided on the peripheral edge portion of the insertion hole 62a, and the connecting belt 25 is smoothly moved by pressing the connecting belt 25 through the sliding surface or the sliding contact surface at the contact position. It can also be made.

  The adjustment plate driving means 65 includes a hydraulic pump, and the adjustment plate 62 protrudes and protrudes vertically from the fixed seat 61 and selectively intersects the track of the connecting belt 25 between the contact position and the separation position. Reciprocating drive is possible in the direction (vertical direction). For example, the adjustment plate driving means 65 moves the adjustment plate 62 up and down by a hydraulic pump through a hydraulic cylinder or the like and arranges the adjustment plate 62 at the contact position and the separation position. At the abutting position, the peripheral edge of the insertion hole 62a of the adjustment plate 62 abuts against the connecting belt 25 and presses the connecting belt 25 to adjust the speed, and at the separated position, the adjusting plate 62 is inserted. The peripheral edge portion of the hole 62a is separated from the connection belt 25 to release the pressure of the connection belt 25. In other words, in the first embodiment, the flywheel 11 is rotationally driven by the prime mover 21 via the connecting belt 25, while the adjusting plate 62 of the adjusting means is moved closer to the connecting belt 25 and connected to the connecting belt 25 as necessary. The contact belt 25 is pressed and the connecting belt 25 is pressed to adjust the speed and looseness of the connecting belt 25.

  In addition, the dimension and weight of the said flywheel 11 grade | etc., Can be set as follows, for example. That is, the flywheel 11 is made of iron or cast iron, is manufactured with a diameter of 100 to 200 cm, a thickness of 20 cm, and a weight of about 300 to 1000 kg, the rotary shaft 13 is manufactured with a diameter of 15 cm, and the pulley 16 is manufactured with a diameter of 50 cm. 41 and 42 are manufactured with a diameter of 30 cm. The base 2 is made of concrete, and the bases 14 and 15 are made of iron or cast iron. Furthermore, a railroad track can be used as the rail 51. The flywheel 11 is thickened by extending the outer peripheral edge portion in a rib shape in the axial direction, and the central rotating shaft 13 portion is projected in a bush shape in the axial direction so that the portion between them is thickened. Although it has a thin shape, it can also have the same thickness as a whole, and can be implemented as any configuration as long as the rotational efficiency of the flywheel 11 can be improved.

Next, a method of using the power generation device according to Embodiment 1 configured as described above will be described.
In order to generate power with the power generation device, first, the generator 31 is moved away from the flywheel 11 by the generator moving means and placed at the release position, and the generator 31 is rotated by the clutch mechanisms 41 and 42. By releasing the connection between the shaft 34 and the rotary shaft 13 of the flywheel 11, the transmission of the rotational force of the flywheel 11 to the generator 31 is cut off. As a result, the clutch mechanisms 41 and 42 are released, and the drive connection between the rotary shaft 13 of the flywheel 11 and the rotary shaft 34 of the generator 31 is released. Next, in this state, the flywheel 11 is rotationally driven via the connecting belt 25 by rotationally driving the prime mover 21. At this time, since the generator 31 is not drivingly connected to the flywheel 11, the load on the flywheel 11 can be made substantially zero, and the prime mover 21 can easily start the rotation of the flywheel 11. Therefore, even when a small motor 21 is used, the heavy flywheel 11 can be easily driven to rotate. For example, the motor 21 having a motor output of 100 horsepower can easily rotate the flywheel 11 having a weight of about 1 t. can do.

  When the flywheel 11 is rotated up to a predetermined maximum rotational speed by the prime mover 21, the generator 31 is moved so as to approach the flywheel 11 by the generator moving means and arranged at the coupling position. By connecting the rotating shaft 34 of the generator 31 and the rotating shaft 13 of the flywheel 11, the rotational force of the flywheel 11 is transmitted to the generator 31. As a result, the clutch mechanisms 41 and 42 are connected to drive and connect the rotary shaft 13 of the flywheel 11 and the rotary shaft 34 of the generator 31. Then, the rotational force of the flywheel 11 is transmitted to the generator 31 via the clutch mechanisms 41 and 42, and the generator 31 generates electric power. At this time, since the flywheel 11 maintains its rotational speed for a predetermined time by its own inertial force, the driving force of the prime mover 21 is set to be higher than when the flywheel 11 starts to rotate (when the speed is increased to the maximum rotational speed). Even if it is made smaller, the maximum rotation speed of the flywheel 11 can be easily maintained. That is, since the flywheel 11 maintains the rotational force by the inertial force, the driving force of the prime mover 21 necessary for maintaining the maximum rotational speed of the flywheel 11 is very small. Therefore, the power generator according to Embodiment 1 can generate power with high efficiency by using the inertial force of the flywheel 11 to rotate the generator 31 with a small driving force of the prime mover 21.

  When it is necessary to adjust the rotational speed or the like of the flywheel 11, the adjusting plate 62 is driven to the contact position by the adjusting plate driving means 65 of the adjusting means, and the connecting belt is driven by the peripheral portion of the insertion hole 62 a of the adjusting plate 62. 25 is pressed. As a result, the speed of the connecting belt 25 is reduced due to the frictional resistance between the peripheral edge of the insertion hole 62 a of the adjusting plate 62 and the connecting belt 25. The speed of the connecting belt 25 can be controlled by controlling the amount of movement of the adjusting plate 62 by the adjusting plate driving unit 65 and increasing / decreasing the pressing force of the connecting belt 25 by the adjusting plate 62. If adjustment of the rotational speed or the like of the flywheel 11 is not necessary, the adjustment plate 62 is driven to the separation position by the adjustment plate driving means 65 of the adjustment means, and the pressing of the connecting belt 25 by the adjustment plate 62 is released.

  On the other hand, when power generation by the power generator 31 is unnecessary, the power generator moving means returns the power generator 31 from the coupling position to the release position with respect to the flywheel 11, and the clutch mechanism 41, 42 rotates the rotating shaft of the power generator 31. The transmission of the rotational force of the flywheel 11 to the generator 31 is interrupted by releasing the connection between the rotation shaft 34 and the rotary shaft 13 of the flywheel 11. As a result, the clutch mechanisms 41 and 42 are released, and the drive connection between the rotary shaft 13 of the flywheel 11 and the rotary shaft 34 of the generator 31 is released. On the other hand, since the flywheel 11 maintains rotation by the inertia force at this time, the flywheel 11 can be used as an energy storage device (power storage device). That is, when power generation is required again, the generator 31 is moved again from the release position to the connection position with respect to the flywheel 11 by the generator moving means, and the rotating shaft of the generator 31 is moved by the clutch mechanisms 41 and 42. By connecting 34 and the rotating shaft 13 of the flywheel 11, the rotational force of the flywheel 11 is transmitted to the generator 31. As a result, the clutch mechanisms 41 and 42 are connected to drive and connect the rotary shaft 13 of the flywheel 11 and the rotary shaft 34 of the generator 31. Then, the rotational force of the flywheel 11 is transmitted to the generator 31 via the clutch mechanisms 41 and 42, and the generator 31 generates electric power. In addition, while using the flywheel 11 as an energy storage device, it is preferable to maintain the maximum rotational speed of the flywheel 21 by the prime mover 21, and thus, the flywheel 21 can store energy for a long time. it can. That is, the power generation apparatus according to Embodiment 1 can generate power with high efficiency using the flywheel 11, and in particular, can improve energy transmission efficiency (conversion efficiency) by the flywheel 11, and as an energy storage apparatus. Can also be used.

FIG. 3 is a front view showing the overall configuration of the power generator according to Embodiment 2 of the present invention. FIG. 4 is an enlarged front view showing the adjusting means of the power generator according to Embodiment 2 of the present invention. FIG. 5 is an enlarged side view showing the adjusting means of the power generator according to Embodiment 2 of the present invention.
The power generation device according to the second embodiment is different from the power generation device according to the first embodiment in the configuration of the adjusting means. Other configurations of the power generation device according to the second embodiment are the same as those of the power generation device according to the first embodiment. Specifically, the adjusting means of the power generation device according to the second embodiment abuts on the connecting belt 25 in a state of approaching the connecting belt 25 and intersects the connecting belt 25 with the track (substantially in the thickness direction, vertical). Direction). On the other hand, the adjusting means releases the pressing of the connecting belt 25 while being separated from the connecting belt 25. Specifically, as shown in FIG. 3, the adjusting means is disposed at a predetermined position near the track of the connecting belt 25, and includes a fixed shelf 161, an adjusting roller driving means 162 including a hydraulic jack, and a fixing bracket 164. And an adjustment roller 166. The fixed shelf 161 is disposed between the tip of the rotating shaft of the prime mover 21 (pulley 22) and the tip of the rotating shaft 13 of the flywheel 11 (pulley 16). Specifically, the fixed shelf 161 is fixed by welding or the like on the front surface (outer surface) of the gantry 14 at a lower position in the vicinity of the connection belt 25 so as to protrude into the front side. The adjustment roller driving means 162 is vertically fixed to the fixed shelf 161, so that the adjustment roller driving means 162 is connected to the tip of the rotating shaft of the prime mover 21 (pulley 22) and the tip of the rotating shaft 13 of the flywheel 11 (pulley). 16). As shown in FIGS. 4 and 5, the adjustment roller driving means 162 has a cylindrical piston 163 that extends and retracts vertically (vertical direction). Further, a cylindrical fixing bracket 164 is fixed to the upper end of the casing portion (cylinder 163 accommodating portion) of the adjustment roller driving means 162 so as to extend coaxially upward. The piston 163 is accommodated in the fixing bracket 164 so as to be slidable in the axial direction. The fixing bracket 164 is preferably fixed to the front surface (outer surface) of the gantry 14 by bolting or the like. Further, the piston 163 has a prismatic shape other than the columnar shape, for example, a prismatic shape with a square cross section, and the fixing bracket 164 has a rectangular columnar shape other than the cylindrical shape, for example, a square tube shape with a square cross section. You can also.

  A substantially channel plate-like case 165 is fixed to the upper end of the piston 163 of the adjusting roller driving means 162. The case 165 is arranged such that its length direction extends in a direction perpendicular to the moving direction of the connecting belt 25 (width direction of the connecting belt 25). Inside the case 165, the adjusting roller 166 is attached via a rotating shaft 167 so as to be rotatable. The adjustment roller 166 is attached to the case 165 so that the rotation shaft 167 extends in the length direction of the case 165. As the adjustment roller 166, for example, a direct roller of 10 cm can be used. Further, the pair of side walls before and after the case 165 (left and right in FIG. 5) has a height at which the upper ends protrude upward from the adjustment roller 166. In FIG. 4, the upper portion of the case 165 is notched and displayed in order to clearly show the positional relationship of the rollers 166. Here, the adjustment roller driving means 162 can move the piston 163 up and down by hydraulic pressure so that the upper end portion (tip portion) of the piston 163 protrudes upward from the upper end of the fixing bracket 164.

  Thereby, the adjustment roller 166 is disposed between the tip of the rotating shaft of the prime mover 21 and the tip of the rotating shaft 16 of the flywheel 11 at a predetermined position on the track of the connecting belt 25, and is orthogonal to the track of the connecting belt 25. The rotating shaft 167 is disposed in the direction of the connecting belt 25 (the width direction of the connecting belt 25), and the rotating shaft 167 is rotatable in the case 165. It is possible to move between the abutting position where it abuts and the outer peripheral surface of the abutting position spaced apart from the connecting belt 25. That is, the adjustment roller driving means 162 can selectively drive the adjustment roller 166 between the contact position and the separation position by moving the piston 163 in and out. Then, when the piston 163 of the adjustment roller driving means 162 is gradually projected in the vertical direction (upward) and the adjustment roller 166 is gradually pushed up through the case 165 and driven to the contact position, the outer peripheral surface of the adjustment roller 166 is connected to the connecting belt. The speed is adjusted by pressing the connecting belt 25 while rotating in synchronization with the movement of the connecting belt 25. At this time, the connecting belt 25 contacts the adjustment roller 166 in the case 165, but during the movement, the connection belt 25 may be displaced in the width direction (the axial direction of the adjustment roller 166) and try to be detached from the adjustment roller 166. is there. However, even in this case, the pair of side walls of the case 165 exists at both ends in the axial direction as the ear-shaped portions of the adjustment roller 166, and prevents the connection belt 25 from being detached from the adjustment roller 166.

Specifically, as shown in FIG. 6, the adjusting unit is disposed at a predetermined position near the track of the connecting belt 25 and includes an adjusting roller driving unit 260 and an adjusting roller 268. The adjustment roller driving means 260 is composed of a four-bar linkage mechanism, and has a driving node 261, a driven node 264, and a swinging node 266. The driving node 261 is attached to the pedestal 14 by a shaft 262 so that it can be tilted slightly from the longitudinal end (upper end in FIG. 6). Further, one end in the length direction of the driving node 261 and one end in the length direction (the left end in FIG. 6) of the driven node 264 are connected to each other by a shaft 263 so as to be relatively rotatable.

Embodiment 4
FIG. 7 is a front view showing the overall configuration of the power generation apparatus according to Embodiment 4 of the present invention. FIG. 8 is an enlarged front view showing the adjusting means of the power generator according to Embodiment 4 of the present invention.
The power generation apparatus according to Embodiment 4 differs from the power generation apparatus according to Embodiment 1 in that the auxiliary prime mover is connected to the flywheel by an auxiliary connection belt, and in the configuration of the adjusting means. Other configurations of the power generation device according to the fourth embodiment are the same as those of the power generation device according to the first embodiment. Specifically, in the power generation device according to Embodiment 4, as shown in FIG. 7, the prime mover 21 is in the vicinity of the rear end portion (right end portion in FIG. 7) of the auxiliary base 3 protruding rearward from the rear end of the base 2. Is arranged. On the other hand, the auxiliary prime mover 321 is disposed in the vicinity of the front end portion (left end portion in FIG. 7) of the base 2. The auxiliary prime mover 321 is preferably configured differently from the prime mover 21. For example, when the prime mover is an electric motor (motor), the auxiliary prime mover 321 is preferably composed of, for example, an internal combustion engine. In this case, it is preferable to use the auxiliary prime mover 321 having a higher horsepower than the prime mover 21. Between the pulley 322 attached to the tip of the rotating shaft (drive rotating shaft) of the auxiliary prime mover 321 and the pulley 16 at the tip of the rotational shaft 13 of the flywheel 11, an auxiliary connecting belt 325 is mounted so as to span. The pulley 322 of 321 and the pulley 16 at the tip of the rotary shaft 13 of the flywheel 11 are connected. The auxiliary connection belt 325 can be constituted by a flat belt, a V-belt or the like, like the connection belt 25. As long as the flywheel 11 can be rotationally driven by the auxiliary prime mover 321, another transmission device can be used instead of the auxiliary coupling belt 325. For example, the pulley 322 of the auxiliary prime mover 321 and the pulley 16 at the tip of the rotary shaft 13 of the flywheel 11 are connected via an indirect transmission device such as a chain other than the connection belt, or a direct transmission device such as a gear or a cam. The power of the auxiliary prime mover 321 can be transmitted to the flywheel 11.

  In the fourth embodiment, it is preferable that a control unit is provided so that the prime mover 21, the auxiliary prime mover, and the 321 can be rotated synchronously. In this way, the rotational speed of the flywheel 11 by the prime mover 21 and the rotational speed of the flywheel 11 by the auxiliary prime mover 321 are matched, and both the prime mover 21 and the auxiliary prime mover 321 are simultaneously used to efficiently rotate the flywheel 11. be able to. On the other hand, both the prime mover 21 and the auxiliary prime mover 321 can be used separately without being used simultaneously. For example, when the flywheel 11 is large (for example, when the diameter is 1.5 to 2 m), in order to start the rotation of the flywheel 11, the motor is determined based on the weight (inertial force) of the flywheel 11. When the horsepower of 21 is insufficient, the flywheel 11 is rotated by the auxiliary prime mover 321 of large horsepower, and when the flywheel 11 starts to rotate and can be rotated with a smaller force due to the inertial force, thereafter, the auxiliary prime mover 321 stops driving and drives the prime mover 21 to continue the rotational drive of the flywheel 11. Alternatively, when the prime mover 21 breaks down or the like, the flywheel 11 may be rotationally driven using the auxiliary prime mover 321. Alternatively, when the flywheel 11 is made larger in size, in order to start the rotation of the flywheel 11, if the horsepower of the auxiliary prime mover 321 is insufficient due to the weight (inertial force) of the flywheel 11, the prime mover When the flywheel 11 is rotated by both of the engine 21 and the auxiliary prime mover 321 and the flywheel 11 starts to rotate with a smaller force due to the inertial force, then the flywheel is driven by one of the auxiliary prime mover 321 and the prime mover 21. 11 rotation drive can also be continued.

  Further, the adjusting means of the power generation device according to the fourth embodiment is in contact with the connecting belt 25 in a state of approaching the connecting belt 25, and the connecting belt 25 intersects the track (substantially in the thickness direction, the vertical direction, etc.). ). On the other hand, the adjusting means releases the pressing of the connecting belt 25 while being separated from the connecting belt 25. Specifically, as shown in FIG. 8, the adjusting means is disposed at a predetermined position in the vicinity of the track of the connecting belt 25, and has an adjusting sliding contact body driving means 360 and an adjusting sliding contact body 365.

The adjustment sliding contact body 365 has a substantially columnar shape or a substantially cylindrical shape in which the axial direction is arranged in a direction (width direction) orthogonal to the track of the connecting belt 25. The adjustment sliding contact body 365 is movable between a contact position where the outer peripheral surface contacts the connecting belt 25 and a separated position where the outer peripheral surface is separated from the connecting belt 25 by the vertical movement of the rack 363. That is, by attaching the adjustment sliding contact body 365 to the tip (upper end) of the rack 363 of the adjustment sliding contact body driving means 360 composed of a rack and pinion gear, the adjustment sliding contact body 365 is moved between the contact position and the separation position. It can be selectively driven between them. Then, when the handle 361 is rotated in the counterclockwise direction in FIG. 7 and the pinion gear 362 is rotated in the counterclockwise direction, the rack 363 moves vertically upward via the gear 364 that meshes with the pinion gear 362. The adjustment sliding contact body 365 at the upper end of the rack 363 becomes the contact position, and the outer peripheral surface of the adjustment sliding contact body 365 contacts the connection belt 25 and presses the connection belt 25. On the other hand, when the handle 361 is rotated in the clockwise direction in FIG. 7 and the pinion gear 362 is rotated in the clockwise direction, the rack 363 moves vertically downward via the gear 364 that meshes with the pinion gear 362, and the rack 363. The adjustment sliding contact body 365 at the upper end is in the separation position, and the outer peripheral surface of the adjustment sliding contact body 365 is separated from the connection belt 25 to release the pressing of the connection belt 25.

When the rotational speed or the like of the flywheel 11 needs to be adjusted, the adjustment sliding contact body 365 is driven to the contact position by the adjustment sliding contact body driving means 360 of the adjustment means, and is connected by the adjustment sliding contact body 365. The belt 25 is pressed. As a result, the speed of the connecting belt 25 is reduced by the frictional resistance between the adjusting sliding contact body 365 and the connecting belt 25. Then, the speed of the connection belt 25 is controlled by controlling the amount of movement of the adjustment slide contact body 365 by the adjustment slide contact body driving means 360 and increasing / decreasing the pressing force of the connection belt 25 by the adjustment slide contact body 365. be able to. When adjustment of the rotational speed of the flywheel 11 or the like is unnecessary, the adjustment sliding contact body 365 is driven to a separated position by the adjustment sliding contact body driving means 360 of the adjustment means, and the connection belt 25 of the adjustment sliding contact body 365 is adjusted. Release the pressure. As the adjusting sliding contact body driving means 360, any configuration other than the above can be used as long as it has the same mechanism as the rack and pinion gear.
