Description

Beschreibung Zweiwellige Schrauben-Verdichter werden in der Regel so ausgeführt, daß die beiden Läufer aus dem gleichen Material, Stahl oder Gußeisen, bestehen und durch besondere Maßnahmen am gegenseitigen Berühren gehindert werden, Diese Maßnahmen können entweder eine Ölspritzung sein oder aber eine mechanische Führung beider Läufer, beispielsweise durch Zahnräder, so daß sich die Läufer nicht berühren können.Description Twin-shaft screw compressors are used as a rule designed so that the two runners are made of the same material, steel or cast iron, exist and are prevented from touching one another by special measures, These measures can either be an oil injection or a mechanical one Guiding both runners, for example by gears, so that the runners do not can touch.

Die Erfindung macht solche Maßnahmen auf einfache Weise dadurch entbehrlich, daß man durch eine besondere Werkstoffauswahl ein Berühren der Rotoren in Kauf nehmen kann. Eine solche Werkstoffauswahl kann eine Kombination aus weichem und hartem Material sein, z. B. Eisen - Nichteisenmetall. Auch die Verwendung von Kunststoffen ist möglich, wobei ein Rotor entweder massiv in Kunststoff ausgeführt oder aber auch mit einem KunsfttoffUberzug beschichtet oder verkleidet sein kann.The invention makes such measures unnecessary in a simple manner, that you accept touching the rotors by choosing a special material can. Such a material selection can be a combination of soft and hard Be material, e.g. B. Iron - non-ferrous metal. Also the use of plastics is possible, with a rotor either made of solid plastic or else can also be coated or clad with a plastic cover.
