Description

本発明は、二重反転プロペラ推進装置に関するものである。   The present invention relates to a counter-rotating propeller propulsion device.

船舶用の推進装置として、従来から二重反転プロペラを用いた二重反転プロペラ推進装置が使用されている。この二重反転プロペラ推進装置の従来の一例は、図８に示されている。すなわち、歯車箱１内に回転可能に枢支されて歯車箱１外方へ延びる内側プロペラ軸２の歯車箱１内側端部には、後プロペラ駆動歯車３が設けられ、内側プロペラ軸２の歯車箱１とは反対側の外側端部には、後プロペラ４が設けられている。後プロペラ駆動歯車３には、歯車箱１内に回転可能に格納された後プロペラ用小歯車５が噛合しており、後プロペラ用小歯車５が設けられた後プロペラ駆動小歯車軸６には、軸継手７を介してＮｏ．１原動機８の出力軸８ａが連結されている。   Conventionally, a counter rotating propeller propulsion apparatus using a counter rotating propeller has been used as a marine propulsion apparatus. A conventional example of this contra-rotating propeller propulsion device is shown in FIG. That is, a rear propeller drive gear 3 is provided at the inner end of the gear box 1 of the inner propeller shaft 2 that is pivotally supported in the gear box 1 and extends outwardly, and the gear of the inner propeller shaft 2 is provided. A rear propeller 4 is provided at the outer end opposite to the box 1. The rear propeller driving gear 3 is meshed with a rear propeller small gear 5 that is rotatably housed in the gear box 1, and the rear propeller driving small gear shaft 6 provided with the rear propeller small gear 5 is disposed on the rear propeller driving gear 6. , Through the shaft coupling 7. 1 The output shaft 8a of the prime mover 8 is connected.

歯車箱１内に回転可能に枢支された外側プロペラ軸９は中空状で、内側プロペラ軸２に回転軸心が内側プロペラ軸２と同一軸心上となるよう、外嵌されており、外側プロペラ軸９の歯車箱１内側端部には、前プロペラ駆動歯車１０が設けられ、外側プロペラ軸９の歯車箱１とは反対側の外側端部には、前プロペラ１１が設けられている。前プロペラ駆動歯車１０には、歯車箱１内に回転可能に格納された前プロペラ用小歯車１２が噛合しており、前プロペラ用小歯車１２が設けられた前プロペラ駆動小歯車軸１３には、軸継手１４を介してＮｏ．２原動機１５の出力軸１５ａが連結されている。   The outer propeller shaft 9 pivotally supported in the gear box 1 is hollow, and is externally fitted to the inner propeller shaft 2 so that the rotation axis is on the same axis as the inner propeller shaft 2. A front propeller drive gear 10 is provided at the inner end of the gear box 1 of the propeller shaft 9, and a front propeller 11 is provided at the outer end of the outer propeller shaft 9 opposite to the gear box 1. The front propeller drive gear 10 is meshed with a front propeller small gear 12 rotatably housed in the gear box 1, and the front propeller drive small gear shaft 13 provided with the front propeller small gear 12 is provided on the front propeller drive small gear shaft 13. , Through the shaft coupling 14. 2 The output shaft 15a of the prime mover 15 is connected.

船舶の推進時にＮｏ．１原動機８が駆動されると、出力軸８ａの回転により、後プロペラ駆動小歯車軸６、後プロペラ用小歯車５、後プロペラ駆動歯車３、内側プロペラ軸２が回転し、内側プロペラ軸２を介して後プロペラ４が回転駆動される。又、Ｎｏ．２原動機１５が駆動されると、出力軸１５ａの回転により、前プロペラ駆動小歯車軸１３、前プロペラ用小歯車１２、前プロペラ駆動歯車１０、外側プロペラ軸９が回転し、外側プロペラ軸９を介して前プロペラ１１が回転駆動される。   No. when the ship is propelled. 1 When the prime mover 8 is driven, the output shaft 8a rotates to rotate the rear propeller driving small gear shaft 6, the rear propeller small gear 5, the rear propeller driving gear 3, and the inner propeller shaft 2, and the inner propeller shaft 2 The rear propeller 4 is driven to rotate. No. 2 When the prime mover 15 is driven, the output shaft 15a rotates to rotate the front propeller driving small gear shaft 13, the front propeller small gear 12, the front propeller driving gear 10, and the outer propeller shaft 9, and the outer propeller shaft 9 The front propeller 11 is driven to rotate.

而して、Ｎｏ．１原動機８及びＮｏ．２原動機１５が駆動された場合、後プロペラ４と前プロペラ１１は逆回転するようにしている。これは、後プロペラ４と前プロペラ１１の回転により船体に作用するカウンタトルクを互いに打ち消し合わせ、船舶の推進を効率良く行なうためである。   Thus, no. 1 prime mover 8 and no. (2) When the prime mover 15 is driven, the rear propeller 4 and the front propeller 11 are rotated in the reverse direction. This is because counter torques acting on the hull due to the rotation of the rear propeller 4 and the front propeller 11 cancel each other, and the vessel is propelled efficiently.

又、上記二重反転プロペラ推進装置の場合、Ｎｏ．１原動機８のみを駆動すると後プロペラ４が単独で回転駆動され、Ｎｏ．２原動機１５のみを駆動すると前プロペラ１１が単独で回転駆動される。   In the case of the counter rotating propeller propulsion device, No. When only the prime mover 8 is driven, the rear propeller 4 is independently driven to rotate. When only the two prime movers 15 are driven, the front propeller 11 is rotated alone.

従来の二重反転プロペラ推進装置としては、特許文献１に示すような装置がある。この装置においても、図８の二重反転プロペラ推進装置と同様、前プロペラが取付けられた外軸と後プロペラが取付けられた内軸は同一軸心上に設けられており、外軸は第１駆動装置によって駆動され、内軸は第２駆動装置によって駆動されるようになっている。   As a conventional contra-rotating propeller propulsion apparatus, there is an apparatus as shown in Patent Document 1. Also in this device, like the counter rotating propeller propulsion device of FIG. 8, the outer shaft to which the front propeller is attached and the inner shaft to which the rear propeller is attached are provided on the same axis, and the outer shaft is the first shaft. The inner shaft is driven by the second driving device.

以下、本発明の実施の形態を図示例と共に説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１〜図５は本発明を実施する実施例１であって、図中、図８と同一の符号を付した部分は同一のものを表わしている。而して、本実施例１においては、前プロペラ駆動小歯車軸１３の軸心方向中途部に、歯車箱１内に格納されるよう、前プロペラ用クラッチ１６を設け、後プロペラ駆動歯車３に噛合した後プロペラ用小歯車５に連動小歯車１７を噛合させ、前プロペラ駆動歯車１０に連動歯車１８を噛合させ、連動小歯車１７と連動歯車１８を、中途部に連動歯車クラッチ１９を備えた連動歯車軸２０に設けている。又、特に図示していないが、各軸類は適宜、軸受により支持され、必要箇所にはシール装置が設けてあるが、これらは周知の手段であるため、説明は省略している。更に、前プロペラ用クラッチ１６、連動歯車クラッチ１９としては、手動式、電動式、油圧式、電磁式等の公知の種々のクラッチを使用することができる。   1 to 5 show a first embodiment for carrying out the present invention. In the figure, the same reference numerals as those in FIG. 8 denote the same parts. Thus, in the first embodiment, a front propeller clutch 16 is provided in the middle of the axial direction of the front propeller drive small gear shaft 13 so as to be housed in the gear box 1, and the rear propeller drive gear 3 After the meshing, the interlocking small gear 17 is meshed with the propeller small gear 5, the interlocking gear 18 is meshed with the front propeller driving gear 10, the interlocking small gear 17 and the interlocking gear 18 are provided, and the interlocking gear clutch 19 is provided in the middle. The interlocking gear shaft 20 is provided. Although not particularly shown, each shaft is appropriately supported by a bearing, and a seal device is provided at a necessary portion. However, since these are well-known means, description thereof is omitted. Further, as the front propeller clutch 16 and the interlocking gear clutch 19, various known clutches such as a manual type, an electric type, a hydraulic type, and an electromagnetic type can be used.

次に、上記実施例１の作動を説明する。
船舶の推進時にＮｏ１．原動機８とＮｏ２．原動機１５の両方を駆動する場合は、前プロペラ用クラッチ１６をオン(連結状態)にし、連動歯車クラッチ１９をオフ(離脱状態)にする。従って、Ｎｏ１．原動機により、出力軸８ａを介して後プロペラ駆動小歯車軸６、後プロペラ用小歯車５、後プロペラ駆動歯車３、内側プロペラ軸２が回転され、内側プロペラ軸２を介して後プロペラ４が回転駆動される。この場合、動力は、後プロペラ用小歯車５から連動小歯車１７に伝達されるが、連動歯車クラッチ１９はオフのため、連動小歯車１７は空転するだけである。 Next, the operation of the first embodiment will be described.
No1. Motor 8 and No2. When both the prime movers 15 are driven, the front propeller clutch 16 is turned on (connected state), and the interlocking gear clutch 19 is turned off (disengaged state). Therefore, No1. The prime mover rotates the rear propeller driving small gear shaft 6, the rear propeller small gear 5, the rear propeller driving gear 3, and the inner propeller shaft 2 through the output shaft 8 a, and the rear propeller 4 rotates through the inner propeller shaft 2. Driven. In this case, power is transmitted from the rear propeller small gear 5 to the interlocking small gear 17, but since the interlocking gear clutch 19 is off, the interlocking small gear 17 only rotates idle.

又、Ｎｏ２．原動機１５により、出力軸１５ａを介して前プロペラ駆動小歯車軸１３、前プロペラ用クラッチ１６、前プロペラ駆動小歯車軸１３、前プロペラ用小歯車１２、前プロペラ駆動歯車１０、外側プロペラ軸９が回転され、外側プロペラ軸９を介して前プロペラ１１が、後プロペラ４の回転方向とは逆回転になるよう、回転駆動される。この場合、前プロペラ駆動歯車１０の回転により連動歯車１８が回転するが、連動歯車クラッチ１９はオフであるため、連動歯車１８は空転するだけである。   In addition, No2. The prime mover 15 causes the front propeller driving small gear shaft 13, the front propeller clutch 16, the front propeller driving small gear shaft 13, the front propeller small gear 12, the front propeller driving gear 10, and the outer propeller shaft 9 to pass through the output shaft 15 a. The front propeller 11 is rotated via the outer propeller shaft 9 so as to rotate in the direction opposite to the rotation direction of the rear propeller 4. In this case, the interlocking gear 18 is rotated by the rotation of the front propeller drive gear 10, but the interlocking gear clutch 19 is off, so that the interlocking gear 18 only idles.

Ｎｏ２．原動機１５を停止し、Ｎｏ１．原動機８を駆動して後プロペラ４及び前プロペラ１１を回転駆動する場合は、前プロペラ用クラッチ１６をオフにし、連動歯車クラッチ１９をオンにする。従って、Ｎｏ１．原動機８の出力軸８ａを介して、後プロペラ駆動小歯車軸６、後プロペラ用小歯車５、後プロペラ駆動歯車３、内側プロペラ軸２が回転し、内側プロペラ軸２を介して後プロペラ４が回転駆動される。又、後プロペラ用小歯車５の回転により、連動小歯車１７、連動歯車軸２０、連動歯車クラッチ１９、連動歯車軸２０、連動歯車１８、前プロペラ駆動歯車１０、外側プロペラ軸９が回転し、外側プロペラ軸９を介して前プロペラ１１が回転駆動される。この場合、前プロペラ駆動歯車１０の回転により前プロペラ用小歯車１２が回転するが、前プロペラ用クラッチ１６はオフであるため、Ｎｏ２．原動機１５が駆動されることはない。   No2. The prime mover 15 is stopped and No1. When driving the prime mover 8 to rotationally drive the rear propeller 4 and the front propeller 11, the front propeller clutch 16 is turned off and the interlocking gear clutch 19 is turned on. Therefore, No1. The rear propeller driving small gear shaft 6, the rear propeller small gear 5, the rear propeller driving gear 3, and the inner propeller shaft 2 rotate via the output shaft 8 a of the prime mover 8, and the rear propeller 4 rotates via the inner propeller shaft 2. Driven by rotation. Further, by the rotation of the rear propeller small gear 5, the interlocking small gear 17, the interlocking gear shaft 20, the interlocking gear clutch 19, the interlocking gear shaft 20, the interlocking gear 18, the front propeller driving gear 10, and the outer propeller shaft 9 are rotated. The front propeller 11 is driven to rotate via the outer propeller shaft 9. In this case, the front propeller small gear 12 is rotated by the rotation of the front propeller driving gear 10, but the front propeller clutch 16 is off. The prime mover 15 is not driven.

実施例１によれば、Ｎｏ２．原動機１５が停止しても、Ｎｏ１．原動機８で後プロペラ４、前プロペラ１１の両方を駆動することができるため、推進効率が悪化することなく、船舶の推進を良好に維持することができる。   According to Example 1, No2. Even if the prime mover 15 stops, No1. Since both the rear propeller 4 and the front propeller 11 can be driven by the prime mover 8, the propulsion of the ship can be maintained well without deteriorating the propulsion efficiency.

又、高負荷域では、Ｎｏ１．原動機８及びＮｏ２．原動機１５の両方を駆動し、低負荷域では、Ｎｏ２．原動機１５を停止し、Ｎｏ１．原動機８のみを駆動すれば、駆動側であるＮｏ１．原動機８の出力は高負荷となり、熱効率が改善される。   In the high load range, No1. Prime mover 8 and No2. Both of the prime movers 15 are driven, and in the low load range, No. 2. The prime mover 15 is stopped and No1. If only the prime mover 8 is driven, No1. The output of the prime mover 8 becomes a high load, and the thermal efficiency is improved.

更に、１台の原動機により後プロペラ４及び前プロペラ１１の両方を回転駆動する場合に、停止側となるＮｏ２．原動機１５をディーゼル機関とし、駆動側となるＮｏ１．原動機８をガス機関、又はデュアルフューエル機関、若しくは電動機とし、Ｎｏ２．原動機１５を停止し、Ｎｏ１．原動機８をを駆動して船舶の推進を行なえば、排気ガス規制海域での排気ガス規制の対応が容易になる。   Further, when both the rear propeller 4 and the front propeller 11 are rotationally driven by one prime mover, No. 2 on the stop side. The prime mover 15 is a diesel engine and No1. The prime mover 8 is a gas engine, a dual fuel engine, or an electric motor. The prime mover 15 is stopped and No1. If the prime mover 8 is driven to propel the ship, it becomes easy to comply with exhaust gas regulations in the exhaust gas regulation sea area.

図６、図７は本発明の二重反転プロペラ推進装置の実施例２であって、図中、図１、図５に示すものと同一の符号を付した部分は同一のものを表わしている。而して、本実施例２においては、先端に後プロペラ４と噛合する後プロペラ用小歯車５が取付けられると共にＮｏ１．原動機８の出力軸８ａに軸継手７を介して連結される後プロペラ駆動小歯車軸６の中途部に、前後プロペラ用クラッチ２１を設けている。   6 and 7 show a second embodiment of the contra-rotating propeller propulsion device according to the present invention. In the figure, the same reference numerals as those shown in FIGS. 1 and 5 denote the same components. . Thus, in the second embodiment, the rear propeller small gear 5 that meshes with the rear propeller 4 is attached to the tip, and No.1. A front and rear propeller clutch 21 is provided in the middle of the rear propeller drive small gear shaft 6 connected to the output shaft 8a of the prime mover 8 via the shaft coupling 7.

斯かる構成とすることにより、後プロペラ４、前プロペラ１１の両方を１台の原動機で回転駆動する際に、Ｎｏ１．原動機８或はＮｏ２．原動機１５の何れかを選択して駆動することができる。   By adopting such a configuration, when both the rear propeller 4 and the front propeller 11 are rotationally driven by one prime mover, No. 1.
