〈産業上の利用分野〉
この発明は船尾スラスタに関し、発電機の負担軽減及び
モータの省略等を目的とするものである。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a stern thruster and aims to reduce the burden on a generator and omit a motor.
〈従来の技術〉
船舶における船尾スラスタは、従来駆動モータにより駆
動されていた。そのため。<Prior Art> A stern thruster in a ship has conventionally been driven by a drive motor. Therefore.
専用の大型モータか必要である上、この大型モータを回

コストか高く、また使用一度もあまり多くないため、非
常に高価な設備となる問題かあった。In addition to requiring a dedicated large motor, the cost is high as it is necessary to increase the capacity of the generator to rotate this large motor, and it is not used very often, making it a very expensive piece of equipment. There was.
〈発明の概要〉
本発明は、上記した点に鑑みてなされたもので、主機の
動力を利用することにより、設備費の低減を図ったもの
である。<Summary of the Invention> The present invention has been made in view of the above points, and aims to reduce equipment costs by utilizing the power of the main engine.
即ち、スラスタを使用する離接岸時には。In other words, when leaving the berth using thrusters.
主機は軽負荷で容量的に余裕かあり、しかも定常回転状
態にあり、更に主機とスラスタは距離的に近いため、主
機からの動力をスラスタに伝達せしめて、スラスタの駆
動を行おうとするものである。The main engine has a light load, has sufficient capacity, and is in steady rotation, and the main engine and thrusters are close to each other, so power from the main engine is transmitted to the thrusters to drive the thrusters. be.
特に可変ピッチプロペラ船では、主機プロペラ軸を一定
の通常回転をさせ、プロペラのピッチのみを変えて運航
しているため、主機から動力をとるのに好適である。In particular, variable pitch propeller ships operate by rotating the main propeller shaft at a constant normal speed and only changing the pitch of the propeller, which is suitable for obtaining power from the main engine.
この目的のため、主機減速機とスラスタをスラスタ駆動
軸とクラッチ及び変速機ヲ介して連結したことを基本的
な特徴とするものである。For this purpose, the basic feature is that the main gear reduction gear and the thruster are connected via a thruster drive shaft, a clutch, and a transmission.
〈実施例〉 以下本発明の実施例を図面に基づいて説明する。<Example> Embodiments of the present invention will be described below based on the drawings.

is a variable pitch propeller, and (51) is a main engine speed reducer, which are connected to the main engine (not shown). A thruster drive shaft (2) is connected to this reducer (51) via a clutch (3), and the other end of this drive shaft (2) is connected to the stern thruster (1). A continuously variable transmission (4) is interposed between the thruster (1) and the drive shaft (2),

By turning off the thruster (1), keeping the thruster (1) inactive, and connecting the clutch (3) when approaching and departing from the shore, power from the main engine can be transmitted to the thruster (1), which can then be operated. becomes.
このように、スラスタ（１）用のモータ等を必要とせず
にスラスタ（１］の稼動が可能となる。In this way, the thruster (1) can be operated without requiring a motor or the like for the thruster (1).
