Abstract

Die Erfindung betrifft ein Rotorpaar für einen Verdichterblock einer Schraubenmaschine, wobei das Rotorpaar aus einem um eine erste Achse (C1) rotierenden Nebenrotor (NR) und einen um eine zweite Achse (C2) rotierenden Hauptrotor (HR) besteht,
wobei die Anzahl der Zähne (z2) beim Hauptrotor (HR) 4 und die Anzahl der Zähne (z1) beim Nebenrotor (NR) 5 beträgt,
wobei die relative Profiltiefe des Nebenrotors PT rel = rk 1 − rf 1 rk 1
Figure imga0001
 mindestens 0,515, und höchstens 0,58, beträgt, wobei es sich bei rk1 um einen um den Außenumfang des Nebenrotors (NR) gezogenen Kopfkreisradius und bei rf1 um einen am Profilgrund des Nebenrotors ansetzenden Fußkreisradius handelt, wobei das Verhältnis vom Achsabstand α der ersten Achse (C1) zur zweiten Achse (C2) und dem Kopfradius rk1 a rk 1
Figure imga0002
 mindestens 1,683, und höchstens 1,836, bevorzugt höchstens 1,782, beträgt, wobei der Hauptrotor mit einem Umschlingungswinkel ΦHR ausgebildet ist, für den gilt 320° ≤ ΦHR ≤ 360°, und wobei vorzugsweise für ein Rotorlängenverhältnis LHR/a gilt: 1 , 4 ≤ L HR / a ≤ 3 , 3 ,
Figure imga0003
 wobei das Rotorlängenverhältnis aus dem Verhältnis der Rotorlänge LHR des Hauptrotors und dem Achsabstand a gebildet ist und die Rotorlänge LHR des Hauptrotors durch den Abstand einer saugseitigen Hauptrotor-Rotorstirnfläche zu einer gegenüberliegenden druckseitigen Hauptrotor-Rotorstirnfläche gebildet ist.
