Abstract

I en utførelse maskineres et lav- eller høytrykks turbinhus (204) på sin utvendige overflate for å danne innskjæringer (302) i omkretsretningen. Innskjæringene kan f.eks. falle sammen med innvendige lokaliseringer av tetninger (210) for bladene (208), eller med "varme flekker" som har blitt identifisert. En avstivningsring (304) kan være påkrympet til fast pasning i hver innskjæring (302) gjennom fremkalling av temperaturdifferanser mellom ringen og huset. Den radialt sammentrykkende omkretskraft som utøves av hver ring kan hindre lav- eller høytrykksturbinhuset i å utvide seg så mye som det ellers ville. I enkelte applikasjoner kan en avstivningsring for bedre bladtuppklaring eller kompensere for "varme flekker", stive av huset, forbedre husets kjøling eller andre fordeler, avhengig av den bestemte applikasjon. I en utførelse kan innskjæringer unngås. I en alternativ utførelse kan C-ringer eller ringer av flere segmenter være sammenbundet ved hjelp av hydrauliske, elektriske eller andre midler, og aktueres av en kontroller for å utøve justerbar, radialt sammentrykkbar omkretskraft. Andre utførelser er beskrevet og kreves beskyttes.
