- the vibration damping mechanism of the second modification shown in FIGS. 4A and 4B is an eccentric weight 24 disposed inside the ladder 4 (lower part in the illustrated example) and rotated by power.
- the eccentric weight 24 is vibrated by being fastened to the electric motor 24a and rotating.

- the position of the center of gravity of the azimuth propelling device 1D also changes, so that the vibration can be controlled by adjusting the liquid surface position without using a special weight, similarly to the vertical movement of the weight 20 shown in FIG. .
- Examples of the filling liquid used in the liquid level tank 25 include lubricating oil and seawater of a mechanism that mechanically transmits the power of the prime mover 5 to the azimuth propelling apparatus 1D.

- seawater When seawater is used as the filling liquid, there is no limit to the amount of seawater that can be used due to the characteristics of a ship that navigates the ocean. Further, unlike the case of using lubricating oil, sludge or the like does not settle in the tank. Even when using seawater, a seawater pump, a seawater filling pipe, a seawater discharge pipe, and the like are required. Each modified example related to such a vibration damping mechanism can also perform automatic vibration damping in combination with the vibration information detection unit 30 and the control unit 40 described above.
- the vibration suppression mechanism is provided in the ladder-equipped azimuth propulsion device in which the fluctuation of the force generated from the propeller 3 increases when the steering angle is large. This makes it possible to suppress the vibration of the entire azimuth thruster. As a result, the ship provided with the ladder-equipped azimuth propulsion device can reduce unpleasant hull vibration by the vibration control mechanism, and can prevent or reduce the failure of related equipment.

Abstract
Description
このようなアジマス推進器には、船内に設置した原動機の動力を機械的な伝達してプロペラを駆動する方式と、ポッド内に設置した電動機に船内で発電した電力を供給してプロペラを駆動する方式とがある。
図6に示すように、アジマス推進器1は、たとえば船舶Sの船尾等に取り付けて使用される。このアジマス推進器1は、図7に示すように、ポッド2と、プロペラ3と、ラダー4とを備えている。
また、船舶Sの船内には原動機5が設置されており、原動機5の動力は、2組の傘歯歯車ユニット6,7を介してプロペラ3に伝達される。
このような振動に関する従来技術としては、たとえば下記の特許文献1に開示されているように、マグナス効果により横方向の揚力を得ることで、小舵角でも所要の舵力を得るようにして振動を抑制する技術が知られている。
本発明は、上記の事情に鑑みてなされたものであり、その目的とするところは、ラダー付きのアジマス推進器において、大きな舵角を取った場合等に発生するアジマス推進器全体の振動を抑制することにある。
本発明の一態様に係るアジマス推進器は、船内に設置した原動機の動力を機械的に伝達し、ラダー形状部を含むストラットを介して船体に取り付けられたポッドのプロペラを駆動するとともに、前記ストラットと一体に前記ポッドが回動するように構成されたアジマス推進器において、前記ストラットの内部に固有振動数を変化させる制振機構が設けられているものである。
また、本発明の一態様に係るアジマス推進器の上記制振機構は、前記ストラット内の下部に配設され、バネ及び減衰器を介して前記ストラットに締結された錘であることが好ましい。
また、本発明の一態様に係るアジマス推進器の上記制振機構は、前記ストラット内に複数配設した液体タンクの液面調整であることが好ましい。この場合に好適な液体タンクの充填液体としては、原動機の動力を機械的に伝達する機構の潤滑油や海水がある。
図1に示す実施形態のアジマス推進器1Aは、船舶Sの船尾等に取り付けて使用される舶用推進装置の一種である。このアジマス推進器1Aは、船舶Sの船内に設置した原動機5の動力を機械的に伝達し、ラダー4として機能するラダー形状部を包含するストラットを介して船体に取り付けられたポッド2のプロペラ3を駆動するとともに、船舶Sに対して、ラダー4として機能するストラットと一体にポッド2が回動する。
さらに、ポッド2の内部に配設された傘歯歯車ユニット7では、垂直駆動軸9の下端部に固定された傘歯歯車7aと、一端にプロペラ3を取り付けたポッド内水平駆動軸10の他端に固定された傘歯歯車7bとの噛合により、垂直方向の駆動力が水平方向に変換されてプロペラ3に伝達される。
このような錘20を用いた制振機構は、錘20を上下に移動させるとアジマス推進器1Aの重心位置や慣性モーメントが変化する。このため、アジマス推進器1Aの固有振動数も変化するので、ラダー4を備えたアジマス推進器1Aが大きな舵角を取った場合において、プロペラ3から発生する大きな力の変動に起因して生じる振動の共振点からずらすことができる。この結果、振動の減衰が可能となる。
振動情報検出部30は、たとえばラダー4の内部に配置して振動を感知する変位計である。この振動情報検出部30で得られた振動情報は、有線もしくは無線により船内適所に設置された別置きの制御部40に送られる。
図3Aおよび図3Bに示す第1変形例の制振機構は、錘21を使用する点では上述した実施形態と同様である。しかし、この変形例では、ラダー4内の下部に配設された錘21の両端が、バネ22及び減衰器23を介してラダー4に締結された構造となっている。
また、バネ22の剛性や減衰器23の減衰性能を可変にすれば、振動の状態に応じて制振機構の制振性を適宜調整可能となる。
この場合、アジマス推進器1Cの振動に対して、偏心錘24が180度位相のずれた力加振を行うことにより、カウンターを当てて振動を抑制することができる。
図示の構成例では、ラダー4の内部において、合計4つの液体タンク25が上下左右に分散配置されているので、各液面タンク25の液面(液体充填量)調整により重量配分も変化する。従って、アジマス推進器1Dの重心位置も変化するので、図1に示した錘20の上下動と同様に、特別な錘を使用しなくても、液面位置の調整により制振することができる。
潤滑油は、2組の傘歯歯車ユニット6,7や図示しない軸受等の潤滑に使用されるものであり、潤滑油タンクから充填用のポンプを用いて各液体タンク25に必要量が供給される。また、各液体タンク25には、それぞれに開閉弁を設けた液体充填配管や液体排出配管が接続されている。液体タンク25の代わりに、潤滑油タンクを複数に分割して分散配置する構造としてもよい。
このような制振機構に関する各変形例は、上述した振動情報検出部30や制御部40との組合せにより、自動制振を行うことも可能である。
本発明は上述した実施形態に限定されることはなく、その要旨を逸脱しない範囲内において適宜変更することができる。
