As shown in FIG. 2, inside the housing 11, a generator 13 driven by rotational power from the outside and a torque increasing disk member 14 for increasing the torque of the rotational power transmitted to the generator 13 The pedestal 12 of the housing 11 is provided with a storage battery 15 capable of storing electricity generated by the generator 13.

Between the torque increasing disk member 14 and the generator 13, rotational power is received from the central shaft 13a passing through the center of the torque increasing disk member 14, and the rotational speed of the received rotational power is amplified. A rotary speed increaser 16 that transmits to the intermediate shaft 13b is provided.

Further, the storage battery 15 is electrically connected to the drive motor 20 and the rotating body auxiliary motor 23, which will be described later, respectively, and serves as a supplementary power source for the initial operation and maintenance / inspection of the drive motor 20 and the rotating body auxiliary motor 23, respectively. It is configured to be usable.

Further, a DC-AC converter 15a is provided inside the generator 13, and the generated electricity is converted from a direct current to an alternating current, and then can be transmitted to the outside via a power transmission line 15b. ing.

The intermediate shaft 13b extending from the rotary speed increaser 16 is connected to the gear box 24, and the input shaft 13c extends from the gear box 24 to connect the generator 13.

Gearbox 24 is not shown, transmitted by shifting the rotational speed of the one shaft that is connected with the gear together multiple sets within a predetermined ratio (gear ratio) in G ₁ in the other axis In this embodiment, G ₁ = 1.8 is set, and the rotation speed of the intermediate shaft 13b is multiplied by 1.8 and transmitted to the input shaft 13c.

Since according to the combination gear includes a gear by the gear box 24, since the torque transmitted is a value that is multiplied by the reciprocal of _{G 1,} the torque of the intermediate shaft 13b is _{^{G 1 -1 = 1 / 1.8 ≒}} 0 It is multiplied by .56 and transmitted to the input shaft 13c.

As shown in FIGS. 2 and 3, the torque increasing disk member 14 has a disc-shaped middle plate 17 penetrating through the central shaft 13a and a specific gravity attached to the outer periphery of the middle plate 17. It is composed of a large material, for example, an annular outer ring frame 18 formed of iron to be heavier than the middle plate 17.

Further, an outer dentition 18a is provided on the outer periphery of the outer ring frame 18 so that the outer ring frame 18 functions as a gear, and is in the shape of a gear that comes into contact with the outer ring frame 18 and meshes with the outer dentition 18a. A contact rotary wheel 19 and a drive motor 20 that rotationally drives the contact rotary wheel 19 to assist the rotation of the torque increasing disk member 14 are adjacent to the torque increasing disk member 14.

Further, a transmission shaft 21 for transmitting rotational power from an external power source (not shown) is inserted in the hole portion 11a. At the end of the transmission shaft 21, a gear-shaped transmission ring 22 that comes into contact with the outer ring frame 18 of the torque increasing disk member 14 and meshes with the outer dentition 18a is provided.

Therefore, when rotational power is transmitted to the power generation device 10 from an external power source through the transmission shaft 21, the torque increasing disk member 14 rotates via the transmission wheel 22, so that the torque is increased by the torque increasing disk member 14. In this state, the central shaft 13a rotates, the rotational speed is amplified by the rotary speed increaser 16, and the generator 13 is driven.

At this time, the rotation of the torque increasing disk member 14 is assisted by the rotation of the contact rotary wheel 19 by the drive motor 20 so as to be kept constant.

Here, how much the torque is increased by the torque increasing disk member 14 is determined by the size and weight of the torque increasing disk member 14. For example, when the outer ring frame 18 of the torque increasing disk member 14 is designed so that the radius r = 3 m, the width d = 0.15 m, and the thickness h = 0.05 m, the mass M thereof is M = π (r). ^2- (rd) ² ) h ・ (iron specific gravity) = π (2rd) dh ・ (iron specific gravity) = π ・ 5.85m ・ 0.15m ・ 0.05m ・ 7.85 ・ 1000kg / m ³ ≈ 1082.023 kg, therefore, the torque T = Mg (rd / 2) of the rotational power transmitted to the generator 13 increases by 1082.023 kgf · 2.925 m ≈ 3164.917 kgf · m, thereby generating electricity. The amount also increases.

4 is an enlarged cross-sectional view of a main part showing the internal structure of the rotary speed increaser 16 of FIG. 2 in a side view, FIG. 5 is a VV cross-sectional view of FIG. 4, and FIG. 6 is FIG. It is an exploded side view which shows the gear mechanism of a rotary speed increaser 16.

As shown in FIGS. 4 to 6, the rotary speed increaser 16 is arranged with the central gear 25 axially routed to the central shaft 13a and the central gear 25 at positions symmetrical with respect to the central shaft 13a. The three built-in gears 26 that mesh with each other and the built-in gear support shaft 27a that is arranged coaxially with the central shaft 13a in a substantially disk shape and supports the three built-in gears 26 on one side of the disk are fixed and the other. An external gear 27b is coaxially attached to one side, and the central shaft 13a is formed by a rotating body 27 having a playable through hole 27c and an annular gear 28 having internal teeth that meshes with each of the three built-in gears 26. It is equipped with a planetary gear mechanism.

Further, the rotary speed increaser 16 is provided with a speed increaser cover 29 which is substantially cylindrical and is attached to an annular gear 28 so as to cover the outside thereof. The speed increaser cover 29 is provided with an opening 29a on one end surface of the cylinder into which the rotating body 27 can be loosely fitted, and an intermediate shaft 13b is connected coaxially with the central shaft 13a on the other end surface.

Further, the external gear 27b attached to the rotating body 27 is arranged so that the rotating body auxiliary gear 23a meshes with the external gear 27b, and the rotating body auxiliary motor 23 for rotationally driving the rotating body auxiliary gear 23a is connected.

When the central shaft 13a is rotated by the planetary gear mechanism of the rotary speed increaser 16, the center gear 25 also rotates, and the rotation is transmitted to the annular gear 28 via the built-in gear 26 to accelerate the speed together with the annular gear 28. The machine cover 29 also rotates integrally, and the intermediate shaft 13b connected to the speed increaser cover 29 also rotates. The rotation direction of the intermediate shaft 13b is opposite to that of the central shaft 13a.

At this time, when the rotating body auxiliary motor 23 is driven to rotate the rotating body auxiliary gear 23a, the external gear 27b rotates via the rotating body auxiliary gear 23a, so that the rotating body 27 interlocking with the external gear 27b is rotated. be able to.

Here, _{N S1} the rotational speed of the ring gear 25, the number of teeth _{Z S1,} the rotational speed _{N C1} of the rotating body 27, the rotational speed _{N R1} of ring gear 28, and the number of teeth and _{Z _R1,} _{N R1} is , planetary expression gear mechanism transmission ratio of the _{_{_{_{(N R1 -N C1) / (}}}} N S1 -N C1) = - from _{_{_{Z S1 / Z R1, N R1}}} = (1 + Z S1 / Z R1) Nc- (Z S1 / It can be calculated as _{Z R1} ) _NS1.

That is, the rotation speed increaser 16 can amplify the rotation speed of the intermediate shaft 13b by synthesizing the rotation speed of the rotating body 27 rotated by the rotating body auxiliary motor 23 with respect to the rotation speed of the central shaft 13a. Further, by adjusting the output of the rotating body auxiliary motor 23, the rotation speed of the intermediate shaft 13b can be adjusted.

In this embodiment, the center gear 25 is a spur gear with 50 teeth, the built-in gear 26 is a spur gear with 25 teeth, and the annular gear 28 is a spur gear with 100 teeth. ..

For example, when the central shaft 13a has a rotation speed of 200 rpm and the rotating body auxiliary motor 23 rotates and drives the rotating body 27 in the direction opposite to the central shaft 13a at a rotation speed of 600 rpm, Z _S1 = 50, Z _R1 = 100, N _S1 = _-200rpm, since _{N C1 = 600rpm, N R1 =} (1 + 50/100) · 600- (50/100) · (-200) = 1000rpm. That is, the rotation speed of the intermediate shaft 13b is amplified to 1000 rpm.

Also, here, _{T S1} torque of ring gear 25, the rotary body 27 of the torque _{T C1,} and efficiency and torque _{T R1} of the annular gear 28, meshing the teeth of the ring gear 25 and internal gear 26, internal gear 26 the meshing efficiency and ₁ meshing efficiency of the overall synthesized gear η of the teeth of the ring gear 28, when the center wheel 25 to the transmission ratio of the ring gear 28 and _{_{_{i 1 = Z R1 / Z S1}}} , T R1 = It is expressed as _{η 1}・ i ₁・ T _S1 + (η ₁・ i ₁ / (1 + η ₁・ i ₁ )) TC _1.

For convenience, when put between the meshing efficiency of the gears _{100% (η 1 = 1)} , since i 1 = 100/50 = 2 , is a _{T R1 = 2T S1 + (2/3} ) T C1.

_{Here, T R1} is equal to the torque of the intermediate shaft _{13b, T S1} is equal to the torque of the central axis _{13a, T C1} is equal to the torque which is introduced from the rotating member the auxiliary motor 23.

That is, the rotation gearbox 16, the torque of the central axis 13a, by combining the torque of the rotating body auxiliary motor 23 by a factor corresponding to the transmission ratio i ₁ of the ring gear 28 from the ring gear 25 to the intermediate shaft 13b Can be communicated.

The torque of the rotating body assisting motor 23 is small against the torque of the center gear 25, which is increased by the torque increase for the disk member 14, _i.e., a T S1 >> _{T _C1,} a _{T R1} ≒ _{2T S1.}

Rotational power of the intermediate shaft 13b, so is transmitted to the generator 13 through the gearbox 24 and the input shaft 13c, the rotational speed of the rotational power transmitted to the final power generator _13, G 1 · 1000 = 1800rpm , the torque becomes _{^{_{G 1 -1 · T R1 = 1.12T}}} S1.

The actual power generation amount is obtained by subtracting the power required for driving the drive motor 20 and the rotating body auxiliary motor 23, but the subtracted power is small compared to the increased power generation amount.

As described above, according to the power generation device 10 which is the first embodiment of the present invention, the torque increasing disk member 14 for increasing the torque of the rotational power transmitted to the generator 13 is provided from the outside. Since the torque of the rotational power can be increased to obtain a larger rotational power, the amount of power generation can be improved.

Further, since the moment of inertia is increased by the amount of the torque increasing disk member 14, the rotational power for driving the generator 13 is less likely to fluctuate, and the voltage of the generated electricity becomes constant, so that the stability of power generation is improved. Can be made to.

Further, a planetary gear mechanism having a center gear 25, a built-in gear 26, a rotating body 27, and an annular gear 28 is provided between the torque increasing disk member 14 and the generator 13, and the rotating body 27 is used as a rotating body auxiliary motor. Since the rotary speed increaser 16 that can be rotationally driven by 23 is provided, the rotational speed of the rotating body 27 can be combined with the rotational speed of the central shaft 13a to increase the rotational speed of the intermediate shaft 13b, and the central shaft can be increased. since it increased by combining the torque of the rotating body auxiliary motor 23 by a factor corresponding to 13a torque of the transmission ratio i ₁ of the center gear 25 and ring gear 28, central shaft which is increased by the torque increase for the disk member 14 The rotational power of 13a can be increased and introduced into the generator 13 without impairing the torque, and the power generation efficiency can be further improved.

Moreover, since the speed increase amount of the intermediate shaft 13b can be adjusted according to the output of the rotary body auxiliary motor 23, the rotational power to be introduced into the generator 13 can be set to an appropriate rotational speed according to the situation, and the power generation efficiency is further improved. Can be made to.

Further, since the drive motor 20 is provided and the rotation of the torque increasing disk member 14 can be assisted via the contact rotary wheel 19, the rotation of the torque increasing disk member 14 can be further stabilized to stabilize the power generation. The torque can be further improved, and the efficiency of power generation can be improved by reducing the load required for the rotational start due to the increase in the moment of inertia.

Further, since the external dentition 18a is provided on the outer periphery of the outer ring frame 18 of the torque increasing disk member 14, the rotational power from the outside can be reliably transmitted to the torque increasing disk member 14, so that the power generation efficiency can be further improved. Can be improved.

Since according to the combination gear includes a gear by the gear box 36, since the torque transmitted is a value that is multiplied by the reciprocal of G _2, the torque of the central axis 33a G ₂ ^{-1 = 3} times has been input shaft 33b Is transmitted to.

FIG. 8 is a cross-sectional view of a main part showing the internal structure of the torque increasing disk member of FIG. 7 in a side view, and FIG. 9 is a cross-sectional view of IX-IX of FIG.

As shown in FIGS. 8 and 9, the torque increasing disk member 34 is arranged at a rotationally symmetric position with respect to the center gear 37 axially passed through the central shaft 33a and the central gear 37. Three built-in gears 38 that mesh with each other and a built-in gear support shaft 39a that is arranged coaxially with the central shaft 33a in a substantially disk shape and supports each of the three built-in gears 38 on one side of the disk, and the other An external gear 39b is coaxially attached to one side, and the central shaft 33a is formed by a rotating body 39 having a playable through hole 39c and an annular gear 40 having internal teeth that meshes with each of the three built-in gears 38. It is equipped with a planetary gear mechanism.

Further, an outer ring frame 41 having a substantially cylindrical shape and having a predetermined weight is attached to the outer circumference of the annular gear 40, and an outer dentition 41a that causes the outer ring frame 41 to function as a gear is provided on the outer circumference of the outer ring frame 41. Has been done.

The load of the outer ring frame 41 is evenly received by the built-in gear 38 arranged rotationally symmetrically inside the annular gear 40, and is supported by the central shaft 33a via the center gear 37.

On the side surface of the outer ring frame 41, a side plate 42a provided with a through hole through which the central shaft 33a can be freely inserted is attached to one side, and a through hole through which the rotating body 39 can be loosely fitted is attached to the other side. A side plate 42b provided with a hole is attached.

The central gear 37, the built-in gear 38, and the annular gear 40 are located between the side plate 42a and the side plate 42b, respectively, and are housed inside the outer ring frame 41. On the other hand, the rotating body 39 protrudes from the side plate 42b to the outside of the outer ring frame 41, and the external gear 39b is exposed to the outside of the outer ring frame 41.

In the vicinity of the torque increasing disk member 34, a drive motor 43 that rotationally drives a gear-shaped contact rotary wheel 43a that meshes with the external tooth row 41a to assist the rotation of the outer ring frame 41, and an external gear outside the outer ring frame 41. A rotating body auxiliary motor 44 that rotationally drives the rotating body auxiliary gear 44a that meshes with the 39b to assist the rotation of the rotating body 39 is provided next to each other.

Further, a transmission shaft 45 for transmitting rotational power from an external power source (not shown) is inserted in the hole portion 31a, and the end portion of the transmission shaft 45 is in contact with the outer ring frame 41 to the outside. A gear-shaped power wheel 46 that meshes with the dentition 41a is provided.

Here, the torque increased by the torque increasing disk member 34 is determined by the size and weight of the outer ring frame 41 and the speed transmission ratio of the planetary gear mechanism.

The torque T increased by the outer ring frame 41 can be calculated in the same manner as in the first embodiment. For example, the outer ring frame 41 is designed to have a radius r = 3 m, a width d = 0.15 m, and a thickness h = 0.05 m. If its mass M ^{is, M = π (r 2 -} (r-d) 2) with h · (iron specific gravity) ≒ 1082.023kg, torque T = Mg (r-d / 2) ≒ 3164.917kgf · m Therefore, the torque of the rotational power transmitted to the generator 33 increases by the amount of T, and the amount of power generation also increases.

When the transmission shaft 45 is rotated by an external power source, rotational power is transmitted from the transmission wheel 46 to the external dentition 41a to rotate the outer ring frame 41 of the torque increasing disk member 34, so that the planetary gear inside the torque increasing disk member 34 is rotated. By the mechanism, the annular gear 40 rotates in conjunction with the outer ring frame 41, and the rotation is transmitted to the center gear 37 via the built-in gear 38, so that the center shaft 33a rotates.

At this time, when the rotating body auxiliary motor 44 is driven to rotate the rotating body auxiliary gear 44a, the external gear 39b rotates via the rotating body auxiliary gear 44a, so that the rotating body 39 interlocking with the external gear 39b is rotated. be able to.

Therefore, when rotational power is transmitted to the power generation device 30 from an external power source through the transmission shaft 45, the torque increasing disk member 34 rotates via the transmission wheel 46, and the torque is increased by the torque increasing disk member 34. Since the central shaft 33a rotates in this state, the rotational speed of the central shaft 33a is amplified by the planetary gear mechanism of the torque increasing disk member 34, and the generator 33 is driven via the gearbox 36 and the input shaft 33b.

At this time, the rotation of the torque increasing disk member 34 is assisted by the rotation of the contact rotary wheel 43a by the drive motor 43 so as to be kept constant.

That is, the torque increasing disk member 34 can amplify the rotation speed of the central shaft 33a by synthesizing the rotation speed of the rotating body 39 rotated by the rotating body auxiliary motor 44 with respect to the rotation speed of the annular gear 40. Further, by adjusting the output of the rotating body auxiliary motor 44, the rotation speed of the central shaft 33a can be adjusted.

Here, the rotational speed _{N S2} of the center gear 37, the number of teeth _{Z S2,} the rotational speed _{N C2} of the rotating body 39, the rotational speed _{N R2} of ring gear 40, and the number of teeth and _{Z _R2,} _{N S2} is _{, NS2} = (1 + Z _R2 / Z _S2 ) _NC2- (Z _R2 / Z _S2 ) N _R2 can be calculated from the speed transmission ratio of the planetary gear mechanism as in the first embodiment.

In this embodiment, the center gear 37 and the built-in gear 38 are formed to have the same diameter (the same number of teeth). _{In this case, assuming} that the number of teeth of the built-in gear 38 is Z _{P2, since Z R2} = Z _S2 + 2Z _P2 = 3Z _S2 from the conditional expression of meshing of each gear of the planetary gear mechanism, it can be understood that Z _R2 / Z _{S2 = 3.}

For example, when the outer ring frame 41 rotates at a rotation speed of 200 rpm by an external rotational power and an auxiliary power of the drive motor 43, the annular gear 40 has a rotation speed of 200 rpm, and the rotating body auxiliary motor 44 makes the rotating body 39 the outer ring frame 41. When the rotation be driven at a rotational speed 1200rpm in the opposite _{_direction,} N R2 = _-200rpm, since _{_{N C2 = 1200rpm, N S2 =}} (1 + Z R2 / Z S2) N C2 - (Z R2 / Z S2) N R2 = 4 · 1200 -3. (-200) = 5400 rpm. That is, the rotation speed of the central axis 33a is amplified to 5400 rpm.

Also, here, _{T S2} torque of ring gear 37, the torque of the rotating body 39 and _{T C2,} torque _{T R2} of the annular gear 40, and the teeth meshing efficiency of the center gear 37 and internal gear 38, internal gear 38 If the meshing efficiency of the entire gear, which is the combination of the meshing efficiency of the gear and the meshing efficiency of _{the ring gear 40, is η 2} , and the speed transmission ratio from the annular gear 40 to the center gear 37 is i ₂ = Z _S2 / Z _R2 , then TS ₂ = It is expressed as _{η 2}・ i ₂・_TR2 + ((η ₂・ i ₂ ) / (1 + η ₂・ i ₂ )) _TC2.

For convenience, if the meshing efficiency of each gear is 100% (η ₂ = 1), i ₂ = 1/3, so _TS2 = (1/3) _TR2 + (1/4) _TC2 . ..

_{Here, T R2} is equal to the torque of the outer ring frame _{41, T S2} is equal to the torque of the central axis _{33a, T C2} is equal to the torque which is introduced from the rotating member the auxiliary motor 44.

That is, the planetary gear mechanism of the torque-increasing disk member 34, the torque of the outer ring frame 41, and combined with the torque of a rotating body the auxiliary motor 44 by a factor corresponding to the transmission ratio i ₂ of the ring gear 37 from the ring gear 40 Can be transmitted to the central axis 33a.

Further, the torque of the rotating body auxiliary motor 44 is very small with respect to the torque of the outer ring frame 41 of the torque increasing disk member 34, that is, _TR2 >> _TC2 and _TS2 ≈ (1/3) _TR2 . ..

Rotational power of the central axis 33a, so is transmitted to the generator 33 through the gearbox 36 and the input shaft 33b, the rotational speed of the rotational power transmitted to the final generator _33, G 2 · 5400 = 1800rpm , the torque becomes _{^{_{_{G 2 -1 · T S2 = T}}}} R2.

The actual power generation amount is obtained by subtracting the power required for driving the drive motor 43 and the rotating body auxiliary motor 44, but the subtracted power is small compared to the increased power generation amount.

As described above, according to the power generation device 30 which is the second embodiment of the present invention, the torque increasing disk member 34 for increasing the torque of the rotational power transmitted to the generator 33 is provided from the outside. Since the torque of the rotational power can be increased to obtain a larger rotational power, the amount of power generation can be improved.

Further, since the moment of inertia is increased by the amount of the torque increasing disk member 34, the rotational power for driving the generator 33 is less likely to fluctuate, and the voltage of the generated electricity becomes constant, so that the stability of power generation is improved. Can be made to.

Further, the torque increasing disk member 34 is provided with a planetary gear mechanism having a center gear 37, a built-in gear 38, a rotating body 39, and an annular gear 40 inside, and the rotating body 39 can be rotationally driven by a rotating body auxiliary motor 44. Therefore, since the rotation speed of the central shaft 33a can be increased by synthesizing the rotation speed of the rotating body 39 with the rotation speed of the annular gear 40 interlocking with the outer ring frame 41, the rotation of the rotational power whose torque is increased by the outer ring frame 41 can be increased. The speed can be increased and introduced into the generator 33, and the power generation efficiency can be further improved.

Further, by providing a planetary gear mechanism capable of speeding up inside the torque increasing disk member 34, the space required in the housing 31 can be reduced, so that the power generation device 30 can be designed compactly.

Moreover, since the speed increase amount of the central shaft 33a can be adjusted according to the output of the rotary body auxiliary motor 44, the rotational power introduced into the generator 33 can be set to an appropriate rotational speed according to the situation, and the power generation efficiency is further improved. Can be made to.

Further, since the drive motor 43 is provided and the rotation of the torque increasing disk member 34 can be assisted via the contact rotary wheel 43a, the rotation of the torque increasing disk member 34 can be further stabilized to stabilize the power generation. The torque can be further improved, and the efficiency of power generation can be improved by reducing the load required for the rotational start due to the increase in the moment of inertia.

Further, since the external dentition 41a is provided on the outer periphery of the outer ring frame 41 of the torque increasing disk member 34, the rotational power from the outside can be reliably transmitted to the torque increasing disk member 34, so that the power generation efficiency can be further improved. Can be improved.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the invention. For example, in both the first embodiment and the second embodiment, the outer ring frame of the torque increasing disk member is made of iron, but if sufficient weight and strength can be secured, another material is used. It may be formed of a material such as lead, stainless steel, precast concrete, or pottery.

Further, the external rotational power to be introduced into the power generation device of the present invention is preferably rotational power from a turbine rotated by wind power, but is not limited to this, and rotational power from other power sources other than wind power may be used.

Further, in the first embodiment and the second embodiment, the number of built-in gears is three in each of the planetary gear mechanisms, but it is not always necessary to be three if the conditions of the planetary gear mechanism are satisfied. It may be 2 or 4 or more. In particular, in the second embodiment, the number of built-in gears may be increased or decreased so as to withstand the load of the outer ring frame according to the design such as the size and weight of the outer ring frame of the torque increasing disk member.
