Description
軸線方向における端に向かって減少する直径を有するテーパー部及び前記テーパー部の大径端に隣接する円柱状部を有する軸と、
前記軸の軸線方向を向いている吸込面を有するとともに前記円柱状部に固定されているインペラであって、常温における飽和蒸気圧が絶対圧で大気圧よりも低い作動流体を前記吸込面に接触させつつ吸い込んで送り出すインペラと、
前記インペラの前記吸込面が向いている方向に前記インペラから離れて配置されて前記軸を支持する軸受であって、前記テーパー部における前記軸の外周面との間に潤滑剤を介在させて前記テーパー部を支持するテーパー支持面と、前記円柱状部における前記軸の外周面との間に潤滑剤を介在させて前記円柱状部を支持する円柱状支持面とを含む支持面を有する軸受と、を備え、
前記軸受の前記支持面のうち前記円柱状支持面の少なくとも一部のみは、黒鉛を6質量%以上含有している銅を主成分とした合金でできている、
ターボ機械を提供する。
本発明者らは、常温(20℃±15℃、日本工業規格:JIS Z 8703)における飽和蒸気圧が絶対圧で大気圧よりも低い作動流体が使用されるターボ機械の信頼性を高めるための検討を行った。検討の結果、テーパー部及び円柱状部を有する軸のテーパー部及び円柱状部を軸受によって潤滑剤を介在させて支持することによりターボ機械の信頼性を高めることができることを見出した。軸がほぼ水平に配置されるようにターボ機械が設置されている場合、軸の重量による鉛直下向きの荷重が軸受のラジアル方向にかかる。軸が高速で回転している状態では、軸の外周面と軸受の支持面との間に存在している潤滑剤の圧力がくさび効果により上昇する。これにより、ラジアル方向の荷重が支持され、軸と軸受との潤滑の状態は流体潤滑の状態である。このため、軸と軸受とが直接接触する固体接触は生じず、軸及び軸受は摩耗しない。
軸線方向における端に向かって減少する直径を有するテーパー部及び前記テーパー部の大径端に隣接する円柱状部を有する軸と、
前記軸の軸線方向を向いている吸込面を有するとともに前記円柱状部に固定されているインペラであって、常温における飽和蒸気圧が絶対圧で大気圧よりも低い作動流体を前記吸込面に接触させつつ吸い込んで送り出すインペラと、
前記インペラの前記吸込面が向いている方向に前記インペラから離れて配置されて前記軸を支持する軸受であって、前記テーパー部における前記軸の外周面との間に潤滑剤を介在させて前記テーパー部を支持するテーパー支持面と、前記円柱状部における前記軸の外周面との間に潤滑剤を介在させて前記円柱状部を支持する円柱状支持面とを含む支持面を有する軸受と、を備え、
前記軸受の前記支持面のうち前記円柱状支持面の少なくとも一部のみは、黒鉛を6質量%以上含有している銅を主成分とした合金でできている、
ターボ機械を提供する。
