Abstract

Die Erfindung betrifft einen schnell drehenden Rotor (10) für eine Vakuumpumpe (2), welcher eine erste Hülse (16) und eine Tragstruktur (14; 60) umfasst. Um die vakuumtechnische Leistungsfähigkeit zu steigern, wird vorgeschlagen, dass innerhalb der ersten Hülse (16) eine zweite Hülse (18) angeordnet ist und erste und zweite Hülse einen Verbund bilden.
