Description
まず、良好なコンテインメント性を確保するには、ハウジングの破断を防止する必要があり、そのためには、ハウジングが、羽根車の破片の衝突エネルギを変形により吸収可能であることが必要である。このような観点から、ハウジングに用いられる樹脂系材料の靱性は高いことが好ましい。
この点、PA46は熱変形量が大きく、PA46を主成分とする樹脂系材料のみからなるハウジングをコンプレッサに用いた場合、良好なコンプレッサ効率を確保することは困難である。
ハブ及び該ハブの外表面に設けられた複数の翼を含む羽根車と、
前記複数の翼より熱変形が大きく、前記羽根車を収容するハウジングと
を備え、
前記ハウジングは、
前記ハブの外表面と対向して前記外表面との間に流体流路を形成しながら前記羽根車を囲むシュラウド部と、
前記シュラウド部と一体に形成され、前記シュラウド部を支持するケーシング部とを有し、
前記シュラウド部は、前記ケーシング部より熱変形量が小さく、温度100度において、静的引張強度65MPa以上200Mpa以下であり、且つ、破断ひずみが0.3mm/mm以下である第1の樹脂系材料を含み、
前記ケーシング部は、前記シュラウド部より高い靭性を有し、温度100度において、静的引張強度が40MPa以上であり、且つ、破断ひずみが0.1mm/mm以上である第2の樹脂系材料を含む。
第1の樹脂系材料の静的引張強度が65MPa以上200MPa以下であり、且つ、破断ひずみが0.3mm/mm以下であるため、コンプレッサの温度上昇によるシュラウド部の熱変形量が小さい。このため、シュラウド部と羽根車の翼との間の隙間が狭小に保たれ、良好なコンプレッサ効率が確保される。
シュラウド部86は第1の樹脂系材料を含み、幾つかの実施形態では、主成分として第1の樹脂系材料を含む。幾つかの実施形態では、シュラウド部86は実質的に第1の樹脂系材料からなる。第1の樹脂系材料は、温度100度において、静的引張強度(最大真応力)が65MPa以上200MPa以下であり、且つ、破断ひずみが0mm/mm超0.3mm/mm以下である。
