Abstract

Die Erfindung betrifft eine Rotorbaugruppe für eine Pumpe mit einer Rotorwelle und einem Rotor, welcher eine Ausnehmung aufweist, in welche die Rotorwelle eingreift, wobei am Außenumfang der Rotorwelle zumindest eine im Querschnitt kreissegmentförmige Tasche und dieser gegenüberliegend am Innenumfang der Ausnehmung des Rotors eine korrespondierende im Querschnitt kreissegmentförmige Tasche ausgebildet ist, wobei in den einander gegenüberliegenden Taschen ein im Querschnitt angepasstes Verbindungselement angeordnet ist.

Figure imgaf001
The invention relates to a rotor assembly for a pump having a rotor shaft and a rotor, which has a recess, in which engages the rotor shaft, wherein on the outer circumference of the rotor shaft at least one circular segment cross-section pocket and this opposite on the inner circumference of the recess of the rotor has a corresponding in cross section is formed circular-segment-shaped pocket, wherein in the opposite pockets a cross-section adapted connecting element is arranged.
