Abstract

Drehkolben- oder Schraubenrotor zum schnelldrehenden Medientransport für einen Verdichter oder ein Gebläse, welcher über mindestens zwei endseitig einer Rotorwelle (5) angeordnete Lagerstellen (6a,6b) drehbar in einer Förderkammer (2) eines mindestens einen Zu- und einen Ablaufanschluss aufweisenden Gehäuses (1) gelagert ist, wobei ein hohler Rotorkörper (7) aus einem kaltgewalzten Metallblech vorgesehen ist, dessen offenen Stirnseiten (8a,8b) über sich radial erstreckende Drehmomentübertragungsmittel an der Rotorwelle (5) angekoppelt sind, und der in der Endform über seine Mantelfläche (11) unmittelbar dynamisch dichtend mit einem massiven oder ebenfalls hohlen Gegenkörper (12) zusammenwirkt.
