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2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3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。
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。
下記の特許文献1には、船内動力を用いてプロペラを回転させる舶用推進装置が開示されており、駆動力伝達系統には傘歯歯車が使用されている。
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、余剰電力を有効に利用して運行費用を削減できるとともに、船体内の構成機器配置自由度を向上させた舶用推進装置を提供することにある。
本発明の一態様に係る舶用推進装置は、駆動軸の動力伝達方向を変換する傘歯歯車ユニットを用い、船内に設置された動力源からポッドのプロペラまで駆動力を伝達する駆動力伝達機構を備えている舶用推進装置において、前記動力源として船内に設置された一対の電動機を備え、前記駆動力伝達機構が、前記電動機に各々連結された一対の船内水平駆動軸から船内傘歯歯車ユニットを介して垂直駆動軸に前記駆動力を伝達し、さらに、前記垂直駆動軸からポッド内傘歯歯車ユニットを介してポッド内水平駆動軸に前記駆動力を伝達して前記プロペラを駆動させるものである。
図1は、舶用推進装置の一例として、アジマス推進器の概略構成例を示している。図示のアジマス推進器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の船内に設置した電動機Mの動力を機械的に伝達し、ラダー形状にした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を駆動して推進力を得る装置である。このアジマス推進器1Aは、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が回動することにより、推進方向を変化させることができる。
電動機Mの動力は、2組の傘歯歯車ユニット、すなわち船内傘歯歯車ユニット6及びポッド内傘歯歯車ユニット7を介してプロペラ3に伝達される。
ポッド2の内部に配設されたポッド内傘歯歯車ユニット7では、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7aと、垂直駆動軸9の下端部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。
駆動力伝達機構は、正転電動機Ma及び反転電動機Mbに各々連結された一対の船内水平駆動軸8a及び船内水平反転軸8bから船内傘歯歯車ユニット6を介して垂直駆動軸9に駆動力を伝達し、垂直駆動軸9からポッド内傘歯歯車ユニット7を介してポッド内水平駆動軸10に駆動力を伝達してプロペラ3を駆動させる。
すなわち、電動機Mは、電源14からコンバータ13を介して供給される余剰電力等により出力を生じるので、この出力による回転トルクの駆動力が駆動力伝達機構を介して海中でプロペラ3を回転させると、船舶Sの推進力が得られる。
電動機Mを一対設けたので、プロペラ3の駆動に必要な出力を二つの電動機Mから確保すればよく、従って、電動機Mの出力を約半分にして小型化することができる。こうして小型化した電動機Mは、大型の電動機と比較すれば、船体内における配置の制約が少ないため自由度は高い。
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。
