Abstract

Skive av en skiverotor for en gassturbin omfatter en sentral del (22), en mellomliggende del (24), en ytterdel (28), en rekke aksiale, gjennomgående hull (27) for en rekke forsterkningsstenger og en rekke slisser (50) for å romme en tilsvarende rekke skovler, idet den sentrale del (22) omfatter et sentralt, aksialt gjennomgående hull (23) i en første krage (30) anbrakt i den første ende og en andre krage (40) anbrakt i en andre ende av den sentrale del (22). Rekken av hull (27) er anbrakt i ytterdelen (28) av skiven for å oppnå høye dynamiske egenskaper av rotoren og samtidig en tilstrekkelig anvendelig levetid.
