Abstract

Die Erfindung betrifft ein Rotorpaar für einen Schraubenverdichter, wobei die Rotoren in kämmendem, berührungslosen Eingriff stehen, die Rotoren jeweils mindestens einen Gang und eine stetige Steigungsänderung aufweisen, wobei die Form der Rotoren durch Schraubenprofile bestimmt ist. Zwischen Herstellungskosten und Anforderungen hinsichtlich der Kenndaten des Verdichters besteht ein Widerspruch. Um hier Verbesserungen zu erzielen, wird vorgeschlagen, das Schraubenprofil jedes Rotors an mindestens zwei axial beabstandeten Stellen mittels verschiedener Profiltypen zu gestalten und die Profiltypen an den Bereichsgrenzen stetig ineinander übergehen zu lassen, wobei die Profiltypen an den jeweiligen Druckbereich angepasst sind.
