Abstract
【解決手段】回転機に対して潤滑油を供給するI/Pオイルパイプの接続部160cと連通油孔76bとの接続部分170が、O/Pオイルパイプの突出ノズル部166aから吐出された潤滑油を第1軸受92aおよび第2軸受96aに供給するために、仕切り壁76の第2軸受保持部100に設けられたオイル導入孔102の開口部よりも上方位置に定められ、接続部分170から流出した潤滑油の少なくとも一部がオイル導入孔102内に流入するようになっているため、潤滑油の粘度が高い極低温時に第1軸受92aおよび第2軸受96aに対する潤滑油の供給量が不足することが抑制される。
【選択図】図6
Description
なお、本明細書における「潤滑」は、摩擦や摩耗を防止するためだけでなく、回転機等に潤滑油を供給して冷却する場合も含む。
上記吐出容量は、1回転当りの潤滑油の吐出量である。
