Description

本発明は、回転増速機能付き発電機及び回転減速機能付き電動機に関する。   The present invention relates to a generator with a rotation acceleration function and an electric motor with a rotation deceleration function.

例えば、プロペラ型の風車発電機では、プロペラの回転を増速して発電部に伝えるため、翼車と発電部とは別に、増速機が備えられている。   For example, in a propeller-type wind turbine generator, a speed increaser is provided separately from the impeller and the power generation unit in order to increase the rotation of the propeller and transmit it to the power generation unit.

しかしながら、発電部とは別に増速機を備えさせると、増速機の設置も考慮に入れた広いスペースを確保しなければならないという問題や、増速機と発電部とが別置きで回転軸にズレを生じるおそれがあるという問題がある。   However, if a gearbox is provided separately from the power generation unit, there is a problem that a large space must be secured in consideration of the installation of the gearbox, and the speedometer and power generation unit are separately installed on the rotating shaft. There is a problem in that there is a risk of deviation.

また、発電回転数の制御を増速機で行うものはなく、発電回転数を制御するには、翼車の回転数を制御することなどで対応しなければならず、応答性の良い回転数制御がなかなか実現できないという問題もある。   In addition, there is no gearbox that controls the power generation speed. To control the power generation speed, the speed must be controlled by controlling the speed of the impeller. There is also a problem that control cannot be realized easily.

本発明は、上記のような問題点に鑑み、省スペースで増速が可能であり、回転軸のズレを生じるおそれもなく、また、発電回転数の制御を応答性良く行うことができる増速機能付き発電機を提供することを課題とする。   In view of the above-described problems, the present invention can increase the speed in a space-saving manner, does not cause a deviation of the rotating shaft, and can increase the speed of power generation with high responsiveness. It is an object to provide a generator with a function.

また、本発明は、発電機と対で考えられる電動機について、省スペースで減速が可能であり、回転軸のズレを生じるおそれもなく、また、電動回転数の制御を応答性良く行うことができる減速機能付き電動機を提供することも、併せて課題とする。   Further, the present invention can reduce the speed of the electric motor considered as a pair with the generator in a space-saving manner, does not cause a deviation of the rotating shaft, and can control the electric rotation speed with high responsiveness. It is also an object to provide an electric motor with a deceleration function.

上記の課題は、対の発電用ローターが備えられ、それらの相対回転で発電をするようになされていると共に、いずれか一方のローターの回転をもう一方のローターの逆方向の回転として伝える伝動機構が備えられ、いずれか一方のローターに入力した回転力で両ローターがそれぞれ逆方向に絶対回転をして発電をするようになされていることを特徴とする、回転増速機能付き発電機によって解決される（第１発明）。   The above-described problem is that a pair of power generation rotors are provided and are configured to generate power by their relative rotation, and transmit a rotation of one rotor as a rotation in the opposite direction of the other rotor. This is solved by a generator with a rotation speed increasing function, characterized in that both rotors rotate in the opposite directions and generate electricity with the rotational force input to one of the rotors. (First invention).

この発電機では、一方のローターに回転が入力されて該ローターが絶対回転をすると、伝動機構を通じてもう一方のローターが逆方向に絶対回転をし、それによって、増速がなされて、前記一方のローターの回転数よりも高い発電回転数を得られる。このように、本発明の発電機は、従来は固定子であったものを回転子とすることで発電機そのものに増速機能をもたせたものであるから、増速を省スペースで実現でき、増速手段の付加による回転軸のズレを生じるおそれもない。   In this generator, when rotation is input to one rotor and the rotor rotates absolutely, the other rotor rotates in the opposite direction through the transmission mechanism, thereby increasing the speed, A power generation rotational speed higher than the rotational speed of the rotor can be obtained. Thus, since the generator of the present invention has a speed increasing function in the generator itself by using a rotor as a conventional stator, speed increase can be realized in a space-saving manner, There is no possibility that the rotation axis is displaced due to the addition of the speed increasing means.

上記の発電機は、例えば、伝動機構として遊星ギア機構を用い、一方のローターに内歯ギアが設けられると共に、もう一方のローターに太陽ギアが設けられ、遊星ギアが両ギアに噛合状態に設置され、いずれか一方のローターの回転でもう一方のローターが逆回転するようになされている構造（第２発明）とすることで、実用的に増速を実現することができる。   The above generator uses, for example, a planetary gear mechanism as a transmission mechanism, an internal gear is provided on one rotor, a sun gear is provided on the other rotor, and the planetary gear is engaged with both gears. By adopting a structure (second invention) in which the rotation of one of the rotors causes the other rotor to rotate in reverse, the speed increase can be realized practically.

特に、この遊星ギア機構において、遊星ギアを太陽ギアの周囲でアクティブに公転動作させる駆動部と、該駆動部による遊星ギアのアクティブな公転動作を制御する制御部とが備えられている場合（第３発明）は、制御部による制御で遊星ギアにアクティブな公転動作を行わせることで、入力側ではないもう一方のローターの回転数を変化させることができて、入力側のローターの回転数を自由に変化させることができない場合であっても、応答性の良い発電回転数制御を実現することができる。   In particular, the planetary gear mechanism includes a drive unit that actively revolves the planetary gear around the sun gear, and a control unit that controls the active revolving operation of the planetary gear by the drive unit (first operation). 3 invention), by making the planetary gear perform an active revolving operation under the control of the control unit, the rotational speed of the other rotor that is not the input side can be changed, and the rotational speed of the rotor on the input side can be changed. Even if it is not possible to change freely, it is possible to realize power generation rotational speed control with good responsiveness.

また、上記の課題は、対の電動用ローターが備えられ、それらの相対回転で電動するようになされていると共に、いずれか一方のローターの回転をもう一方のローターの逆方向の回転として伝える伝動機構が備えられ、入電することにより、両ローターがそれぞれ逆方向に絶対回転をしていずれか一方または両方のローターの回転が出力されるようになされていることを特徴とする、回転減速機能付き電動機（第４発明）によって解決される。   In addition, the above-described problem is that a pair of electric rotors are provided and are electrically driven by their relative rotation, and the transmission of transmitting the rotation of one of the rotors as the rotation in the opposite direction of the other rotor. With a speed reduction function, which is equipped with a mechanism, and when the power is input, both rotors rotate in the opposite directions and the rotation of one or both rotors is output. This is solved by the electric motor (fourth invention).

この電動機では、入電により、一方のローターが絶対回転をすると、伝動機構を通じてもう一方のローターが逆方向に絶対回転をし、それによって、減速がなされる。このように、本発明の電動機は、従来は固定子であったものを回転子とすることで電動機そのものに減速機能をもたせたものであるから、減速を省スペースで実現でき、減速手段の付加による回転軸のズレを生じるおそれもない。   In this electric motor, when one rotor rotates absolutely due to power input, the other rotor rotates in the opposite direction through the transmission mechanism, thereby decelerating. As described above, the electric motor according to the present invention has a speed reduction function in the motor itself by using a rotor as a rotor in the past, so that the speed reduction can be realized in a small space and the addition of speed reduction means. There is no risk of misalignment of the rotating shaft.

上記の電動機は、例えば、伝動機構として遊星ギア機構を用い、一方のローターに内歯ギアが設けられると共に、もう一方のローターに太陽ギアが設けられ、遊星ギアが両ギアに噛合状態に設置され、いずれか一方のローターの回転でもう一方のローターが逆回転するようになされている構造（第５発明）とすることで、実用的に減速を実現することができる。   The above-mentioned electric motor uses, for example, a planetary gear mechanism as a transmission mechanism, an internal gear is provided on one rotor, a sun gear is provided on the other rotor, and the planetary gear is installed in mesh with both gears. By adopting a structure (the fifth invention) in which the other rotor is rotated in the reverse direction by the rotation of one of the rotors, the deceleration can be realized practically.

特に、この遊星ギア機構において、遊星ギアを太陽ギアの周囲でアクティブに公転動作させる駆動部と、該駆動部による遊星ギアのアクティブな公転動作を制御する制御部とが備えられている場合（第６発明）は、制御部による制御で遊星ギアにアクティブな公転動作を行わせることで、応答性の良い電動回転数制御を実現することができる。   In particular, the planetary gear mechanism includes a drive unit that actively revolves the planetary gear around the sun gear, and a control unit that controls the active revolving operation of the planetary gear by the drive unit (first operation). In the invention 6), it is possible to realize electric rotation speed control with good responsiveness by causing the planetary gear to perform an active revolving operation under the control of the control unit.

本発明の発電機は、以上のとおりのものであるから、省スペースで増速が可能であり、回転軸のズレを生じるおそれもなく、また、発電回転数の制御を応答性良く行うことができる。また、本発明の電動機は、省スペースで減速が可能であり、回転軸のズレを生じるおそれもなく、また、電動回転数の制御を応答性良く行うことができる。   Since the generator according to the present invention is as described above, the speed can be increased in a small space, there is no possibility of causing a shift of the rotating shaft, and the power generation speed can be controlled with good responsiveness. it can. Further, the electric motor of the present invention can be decelerated in a space-saving manner, there is no possibility of causing a deviation of the rotating shaft, and the electric rotational speed can be controlled with good responsiveness.

次に、本発明の実施最良形態を図面に基づいて説明する。   Next, the best mode for carrying out the present invention will be described with reference to the drawings.

図１及び図２に示す実施形態は、風力発電に用いられる発電機に適用した場合のもので図１において、１は回転増速機能付き発電機、２はプロペラ型の翼車であり、回転軸３によって翼車２の回転が発電機１に伝えられるようになされている。   The embodiment shown in FIGS. 1 and 2 is applied to a generator used for wind power generation. In FIG. 1, 1 is a generator with a rotation speed increasing function, and 2 is a propeller-type impeller. The rotation of the impeller 2 is transmitted to the generator 1 by the shaft 3.

発電機１は、ベースとなる鞘管４内に、発電用のアウターローター５がローラー６…などで回転自在に支承され、アウターローター５の内部に同じく発電用のインナーローター７が同軸状態で回転自在に配置され、インナーローター７は、翼車２の回転軸３に従来のような増速機を介さずに接続されている。   In the generator 1, an outer rotor 5 for power generation is rotatably supported by a roller 6, etc. in a sheath tube 4 as a base, and an inner rotor 7 for power generation is also rotated in a coaxial state inside the outer rotor 5. Arranged freely, the inner rotor 7 is connected to the rotating shaft 3 of the impeller 2 without using a conventional speed increaser.

そして、同発電機１には、インナーローター７の回転をアウターローターの逆方向の回転として伝える伝動機構８が備えられている。該伝動機構８は遊星ギア機構からなっていて、該遊星ギア機構８は、アウターローター５内にインナーローター７と隣り合うようにして組み込まれている。即ち、アウターローター５の内周部には内歯ギア９が設けられると共に、インナーローター７には太陽ギア１０が連結され、遊星ギア１１…が両ギア９，１０に噛合状態に配置され、インナーローター７の回転によってアウターローター５がインナーローター７とは逆の方向に回転するようになされている。   The generator 1 is provided with a transmission mechanism 8 that transmits the rotation of the inner rotor 7 as the rotation of the outer rotor in the reverse direction. The transmission mechanism 8 includes a planetary gear mechanism, and the planetary gear mechanism 8 is incorporated in the outer rotor 5 so as to be adjacent to the inner rotor 7. That is, an internal gear 9 is provided on the inner peripheral portion of the outer rotor 5, a sun gear 10 is connected to the inner rotor 7, and the planetary gears 11 are arranged in mesh with both gears 9, 10, The outer rotor 5 is rotated in the opposite direction to the inner rotor 7 by the rotation of the rotor 7.

そして、本実施形態では更に、各遊星ギア１１…を、それらの相対位置関係を一定に保つようにして自転自在に保持する遊星ギア保持体１２が備えられると共に、該保持体１２を通じて、遊星ギア１１…を太陽ギア１０の周囲でアクティブに公転動作させる駆動部１３が備えられると共に、該駆動部１３による遊星ギア１１…のアクティブな公転動作を制御する制御部１４が備えられており、各遊星ギア１１を追従公転ではなく、積極公転させることができるようになされている。   In this embodiment, the planetary gears 11 are further provided with planetary gear holders 12 that hold the planetary gears 11 in a rotatable manner so that their relative positional relationship is kept constant. 11 is provided with a drive unit 13 that actively revolves around the sun gear 10 and a control unit 14 that controls the active revolving operation of the planetary gears 11 by the drive unit 13. The gear 11 can be actively revolved instead of following revolving.

上記の発電機１では、風車の翼車２の回転でインナーローター７が絶対回転をすると、遊星ギア機構８を通じてアウターローター５が逆方向に絶対回転をし、それによって、増速がなされて、翼車２の回転数よりも高い発電回転数を得られる。このように、上記の発電機１では、従来は固定子であったものを回転子とすることで発電機１そのものに増速機能をもたせたものであるから、増速を省スペースで実現でき、増速手段の付加による回転軸のズレを生じるおそれもない。   In the generator 1 described above, when the inner rotor 7 rotates absolutely by the rotation of the windmill 2, the outer rotor 5 rotates in the opposite direction through the planetary gear mechanism 8, thereby increasing the speed. A power generation rotational speed higher than the rotational speed of the impeller 2 can be obtained. In this way, in the generator 1 described above, since the generator 1 itself has a speed increasing function by using a rotor as a rotor, speed increase can be realized in a space-saving manner. Further, there is no possibility that the rotational shaft is displaced due to the addition of the speed increasing means.

特に本実施形態では、伝動機構として、遊星ギア機構８を採用し、制御部１４と駆動部１３とによって、遊星ギア１１…を太陽ギア１０の周囲でアクティブに公転動作させることができるようなされているので、翼車２の回転数を変化させなくても、アウターローター５の回転数を変化させることを通じて、発電回転数を制御することができ、しかも、それを遊星ギア１１…のアクティブな公転動作で行うようにしているので、翼車２の回転数を制御する場合などに比べて、応答性に非常に優れた発電回転数制御を実現することができる。   In particular, in this embodiment, the planetary gear mechanism 8 is employed as the transmission mechanism, and the planetary gears 11 can be actively revolved around the sun gear 10 by the control unit 14 and the drive unit 13. Therefore, even if the rotational speed of the impeller 2 is not changed, the rotational speed of the power generation can be controlled by changing the rotational speed of the outer rotor 5, and it is used for the active revolution of the planetary gear 11. Since the operation is performed by the operation, it is possible to realize the power generation rotational speed control which is very excellent in responsiveness as compared with the case where the rotational speed of the impeller 2 is controlled.

具体的には、図２（イ）に示すように、遊星ギア１１…の公転を阻止した状態、あるいは、遊星ギア１１…を追従公転させている状態から、図２（ロ）に示すように、遊星ギア１１…を一方の方向にアクティブに公転させると、インナーローター７の回転数の変化が鈍くても、アウターローター５の回転が速められることで発電回転数を高めることができ、また、図２（ハ）に示すように、遊星ギア１１…を反対の方向にアクティブに公転させると、インナーローター７の回転数の変化が鈍くても、アウターローター５の回転が遅められることで発電回転数を低くすることができる。   Specifically, as shown in FIG. 2 (a), as shown in FIG. 2 (b), the planetary gears 11 are prevented from revolving or the planetary gears 11 are made to follow and revolve as shown in FIG. When the planetary gears 11 are actively revolved in one direction, even if the change in the rotation speed of the inner rotor 7 is slow, the rotation speed of the outer rotor 5 can be increased to increase the power generation rotation speed. As shown in FIG. 2C, when the planetary gears 11 are actively revolved in the opposite direction, the rotation of the outer rotor 5 is slowed down even if the change in the rotational speed of the inner rotor 7 is slow. The number of rotations can be lowered.

以上に、本発明の実施形態を示したが、本発明はこれに限られるものではなく、発明思想を逸脱しない範囲で各種の変更が可能である。例えば、上記の実施形態では、インナーローターに風車の翼車２の回転軸３を連結した場合を示しているが、アウターローターの側に風車の翼車２の回転軸３を連結する構成としてもよい。また、上記の実施形態では、一方のローターをアウターローターとし、もう一方のローターをインナーローターとして場合を示しているが、本発明はアウター・インナー形式のローターに限られるものではない。   Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above embodiment, the case where the rotating shaft 3 of the windmill impeller 2 is connected to the inner rotor is shown, but the rotating shaft 3 of the windmill impeller 2 may be connected to the outer rotor side. Good. In the above embodiment, the case where one rotor is an outer rotor and the other rotor is an inner rotor is shown, but the present invention is not limited to an outer / inner rotor.

また、上記の実施形態では、伝動機構として、遊星ギア機構８を採用した場合を示しているが、それに限らず、いずれか一方のローターの回転をもう一方のローターの逆方向の回転として伝える機構が備えられていればよい。   In the above embodiment, the planetary gear mechanism 8 is used as the transmission mechanism. However, the present invention is not limited to this, and a mechanism that transmits the rotation of one of the rotors as the rotation of the other rotor in the reverse direction. If it is provided.

更に、上記の実施形態では、風力発電用の発電機に適用した場合を示しているが、その他の発電機として用いられてもよいし、また、上記の増速機能付き発電機を、構成を同一類似にして、減速機構付き電動機として用いてもよい。   Furthermore, in the above-described embodiment, the case where the present invention is applied to a generator for wind power generation is shown. However, the generator may be used as another generator, and the generator with the speed increasing function may be configured as described above. You may use it as an electric motor with a speed reduction mechanism in the same manner.
