Abstract

PURPOSE:To aim at improvements in propulsion efficiency by a propeller, by reducing a rotational flow to be generated rearward the propeller with both upper and lower rotors combined. CONSTITUTION:At a stern rear end part more frontward than a propeller 2, there are provided with an upper rotor 7a and a lower rotor 7b at both upper and lower parts of a propeller shaft 3 free of rotation with a rotation axis in vertical directions as the center. The upper rotor 7a and the lower rotor 7b are made so as to be rotated and driven in the opposite direction with each other by a rotor rotation drive mechanism so as to make a flow of water flowing in the propeller 2 twist in the opposite direction to a direction of rotation in the propeller 2. Rotation of the propeller shaft 3 is transmitted to the upper rotor 7a and the lower rotor 7b via a power transmission mechanism whereby these rotors 7a and 7b are rotated and driven in the opposite direction with each other according to rotation of the propeller 2. With this constitution, a rotational flow due attributable to the propeller 2 is brought to nothing, thus propulsion efficiency is improved.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、船尾部の後方にプロペラをそなえた船舶に関
し、特にその船尾部に推進効率を向上するためのロータ
を有する船舶に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ship having a propeller at the rear of the stern, and more particularly to a ship having a rotor at the stern for improving propulsion efficiency.

〔従来の技術〕[Conventional technology]

一般に船舶にはその船尾部の後方にプロペラがそなえら
れており、同プロペラが一定方向に回転することによっ
て船体に推進力を与えている。Generally, a ship is equipped with a propeller at the rear of the stern, and the propeller rotates in a fixed direction to provide propulsive force to the ship.

しかし、プロペラの後方にはプロペラの回転に伴う回転
流が残存するため、この回転流の回転エネルギー分だけ
プロペラによる推進力が低下することになる。However, since a rotational flow accompanying the rotation of the propeller remains behind the propeller, the propulsive force by the propeller is reduced by the rotational energy of this rotational flow.

そこで、従来、船体の船尾部を左右非対称な形状に形成
して、プロペラへ流入する水の流れにあらかじめプロペ
ラの回転方向と逆方向のひねりを与え、このようにして
ひねられた流れとプロペラの回転に起因する回転流とを
互いに打ち消し合わせることによって、プロペラ後方に
′発生する回転流を減少させ、プロペラによる推進効率
を向上させることが行なわれている。Therefore, in the past, the stern of the ship was formed into an asymmetrical shape to give the flow of water flowing into the propeller a twist in the direction opposite to the direction of rotation of the propeller. By canceling out the rotational flow caused by the rotation, the rotational flow generated behind the propeller is reduced and the propulsion efficiency of the propeller is improved.

すなわち、第５，６図に示すように、船体１の船尾部に
は、プロペラ２がプロペラ軸３の先端に取り付けられて
そなえられており、同プロペラ２は図中の矢印方向（右
回り）に回転駆動される。That is, as shown in FIGS. 5 and 6, a propeller 2 is attached to the tip of a propeller shaft 3 at the stern of the hull 1, and the propeller 2 moves in the direction of the arrow (clockwise) in the figure. Rotationally driven.

また、プロペラ２の後方には、舵４が舵支持部材５を介
して船体１に支持されている。Further, behind the propeller 2, a rudder 4 is supported by the hull 1 via a rudder support member 5.

そして、プロペラ２の前方の船尾端１３が、第５〜８図
に示すように、プロペラ軸３より上方部において左舷徊
へ、プロペラ軸３より下方部において右舷側へひねられ
、船体１の船尾部が左右非対称な形状に形成される。Then, the forward stern end 13 of the propeller 2 is twisted to the port side above the propeller shaft 3 and to the starboard side below the propeller shaft 3, as shown in FIGS. The parts are formed in a laterally asymmetrical shape.

。つまり、プロペラ２へ流入する水の流れはプロペラ２
の回転方向と逆方向にひねられた流れとなる。Therefore, the flow of water flowing into the propeller 2 at the stern part is given a leftward twist at the upper part of the propeller shaft 3, as shown by the arrow 14a in FIG. In the lower part, a rightward twist is applied, as shown by arrow 14b in FIG. In other words, the flow of water flowing into propeller 2 is
The flow is twisted in the opposite direction to the direction of rotation.

し、プロペラ２による推進効率が高められるのである。This creates the twisted flow and propeller 2 as described above.
The rotational flow caused by the rotation of the propeller 2 cancels each other out, the rotational energy of the rotational flow flowing out behind the propeller 2 is reduced, and the propulsion efficiency of the propeller 2 is increased.

なお、第５，６図中の符号１０はプロペラ２先端の回転
軌跡、１２は船体中心線を示している。In addition, the reference numeral 10 in FIGS. 5 and 6 indicates the rotation locus of the tip of the propeller 2, and 12 indicates the center line of the hull.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

しか、しながら、上述のような従来の左右非対称船尾形
状を有する船舶では、船尾部が一般の船舶に比べて非常
に複雑な形状となるため、その建造に多くの労力を要す
るとともに、建造費用が増大するという問題点がある。However, in ships with the conventional asymmetrical stern shape as described above, the stern section has a much more complex shape than that of ordinary ships, which requires a lot of labor and construction costs. There is a problem that the amount increases.

また、既存の船舶をこのような船尾形状に改造すること
は非常に困難である。Furthermore, it is extremely difficult to modify an existing ship into such a stern shape.

さらに、船尾部が大きくひねられているので、船舶の船
体抵抗が増大し、プロペラによる推進効率が向上したと
しても、船舶全体としての推進効率は必ずしも向上しな
いという問題点もある。Furthermore, since the stern section is largely twisted, the hull resistance of the vessel increases, and even if the propulsion efficiency of the propeller is improved, there is also the problem that the propulsion efficiency of the vessel as a whole does not necessarily improve.

An upper rotor and a lower rotor are provided above and below the propeller shaft, respectively, and are mounted on the stern hull, and the upper rotor and the lower rotor are oriented in opposite directions around a rotational axis in a substantially vertical direction. A rotor rotation drive mechanism that can be rotationally driven is provided, and the rotor rotation drive mechanism is configured as a power transmission mechanism that transmits rotation of the propeller shaft to the upper rotor and the lower rotor.

互いに逆向きに回転駆動されるようになっている。Moreover, these upper rotor 7a and lower rotor 7b are
The rotors are rotated in opposite directions by a rotor rotation drive mechanism so that the flow of water flowing into the propeller 2 is twisted in a direction opposite to the rotation direction of the propeller 2.

下部ロータ７ｂとが互いに逆方向に回転駆動される。With the above-described configuration, when the ship with the stern rotor of the present invention is sailing, the propeller shaft 3 is rotated in the direction of the arrow in FIGS. 1 and 2. The rotation of this propeller shaft 3 is
The power is transmitted to the upper rotor 7a and the lower rotor 7b through a power transmission mechanism constituted by bevel gears 8a, 8b, and 9, and the upper rotor 7a and the lower rotor 7b move in opposite directions according to the rotation of the propeller 2. Rotationally driven.

る。Therefore, the flow of water flowing into the propeller 2 at the stern section is given a leftward twist by the rotation of the upper rotor 7& at the upper section of the propeller shaft 3, as shown by the arrow 11a in FIG. On the other hand, the lower part of the propeller shaft 3 is twisted to the right by the rotation of the lower rotor 7b, as shown by the arrow 11b in FIG.

がはかれるのである。As a result, the flow of water flowing into the propeller 2 is twisted in the opposite direction to the rotation direction of the propeller 2, and the thus twisted flow and the rotational flow caused by the rotation of the propeller 2 cancel each other out, causing the propeller The rotational energy of the rotational flow flowing out to the rear of 2 is reduced. Therefore, the propulsion efficiency of the propeller 2 can be improved without increasing the hull resistance.

調整されるのである。Moreover, since the rotation of the upper rotor 7a and the lower rotor 7b is performed by transmitting the rotation of the propeller shaft 3,
Their rotational speeds change depending on the rotational speed of the propeller shaft 3, that is, the rotational speed of the propeller 2. Therefore, depending on the strength of the rotational flow caused by the rotation of the propeller 2,
The torsional combination of the water flow into the propeller 2 is automatically adjusted.
