Description
主軸のスカート部15が回転すると油槽4中の潤滑油が軸受16に設けられたねじ溝6を伝わり上昇する。この時潤滑油は、主軸のスカート部15と軸受16との間で発生する摩擦熱を吸収して温度が上昇する。そして油槽の天板7の上に流れ出ると、潤滑油は熱交換器収納体5に遮られることなく天板7に開けた返油穴8に達する。この後潤滑油はガイド管9を通り油槽4へ流入する。このときの落差により潤滑油は加勢され、ガイド管9の出口端から吐出される。

- 潤滑油によって冷却される軸受部と、返油穴を有する天板と、前記軸受部から排出され前記天板の上面を流れる潤滑油を前記返油穴を通して回収する油槽と、複数のヒートパイプを内蔵し前記ヒートパイプの両端部の前後に開口を設けその一端を前記油槽に侵漬した熱交換器収納体とを有する立軸水車の軸受冷却装置において、
前記返油穴からその下部の油槽に潤滑油を案内するガイド管を有し、前記ガイド管は一端を前記返油穴に固着され、前記ガイド管の他端から潤滑油が吐出される方向が油槽内を流れる潤滑油の流線方向と平行となり、さらに潤滑油の吐出方向に沿った潤滑油の流線上に前記熱交換器収納体の開口部を配置したことを特徴とする立軸水車の軸受冷却装置。
- 前記ガイド管からの潤滑油の吐出方向に沿った潤滑油の流線上に、前記熱交換器収納体の開口部を前記流線に対して略直角に配置したことを特徴とする、請求項1に記載した立軸水車の軸受冷却装置。
- 前記ガイド管において、入口径より出口径を同じかまたは大きくしたことを特徴とする請求項1及び請求項2に記載した立軸水車の軸受冷却装置。
