Abstract (en)

The turbo molecular pump has rotor discs (10) and stator discs (14) stacked in alternation within a cylindrical pump housing, cooperating for providing a pump effect. Each stator disc has a distance ring (16) which determines the distance between adjacent stator discs, with part (17) of the cylindrical housing forming an integral stator element (12). The rotor discs are attached to a rotor shaft (4) via clamp elements (24).

Abstract (de)

Die Erfindung beschreibt eine Turbomolekularpumpe mit Rotor- (10) und Statorscheiben (14), welche abwechselnd hintereinander angeordnet sind und durch ihr Zusammenwirken einen Pumpeffekt erzeugen. Jeweils eine Statorscheibe (14) bildet mit einem Distanzring (16), welcher den Abstand zwischen den Statorscheiben fixiert, und einem Teil (17) des zylindrischen Gehäuses ein einstückiges Statorelement (12). Die Rotorscheiben (10) werden mit Klemmvorrichtungen (24) auf der Rotorwelle (4) befestigt. Dadurch wird eine Montage mit ungeteilten Statorscheiben ermöglicht. <IMAGE>
