Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung einer Rotoranordnung für eine Vakuumpumpe und Rotoranordnung für eine Vakuumpumpe, insbesondere für eine Turbomolekularpumpe, welche eine Rotorwelle (10), wenigstens eine mit der Rotorwelle verbundene Rotorscheibe (12) und wenigstens einen die Rotorscheibe umgebenden Armierungsring (14) aufweist. Das Verfahren umfasst, dass zwischen dem Armierungsring (14) und der Rotorscheibe (12) eine Querpressverbindung, insbesondere eine Dehnpressverbindung oder eine Schrumpfpressverbindung, ausgebildet wird.
