Nach dem Festspannen der Turbolader-Rumpfgruppe 4 an dem Verdichtergehäuse 2 wird das Turbinengehäuse 1 in die in der Zeichnung dargestellte Position gebracht und am Maschinenbett 3 befestigt. Durch einen einstellbaren Anschlag 32 kann die geeignete Stellung des Turbinengehäuses 1 am Maschinenbett festgelegt sein. In dieser Stellung gelangt das an dem Ringbund 10 anliegende Hitzeschutzschild 12 des Mittelgehäuses 5 zur Ablage an dem Lagerelement 16 und die Federn 17 und 26 werden in axialer Richtung soweit gespannt, dass das Mittelgehäuse 5 sicher und begrenzt beweglich von den Lagerelementen 16, 25 gehalten ist. In dieser Position haben der Rotor 6 und das Mittelgehäuse 5 gegenüber dem Turbinengehäuse 1 und dem Verdichtergehäuse 2 jeweils einen solchen Abstand, dass es infolge der während eines Messlaufs auftretenden Schwingungen nicht zu einer Berührung zwischen ihnen kommt. Nachdem das Mittelgehäuse 5 zwischen den Lagerelementen 15, 25 eingespannt ist, wird die Spannvorrichtung 23 geöffnet, wodurch die Spannhebel 24, wie in der unteren Hälfte der Zeichnung gezeigt, von dem Flansch 9 entfernt werden. Die Turbolader-Rumpfgruppe 4 kann nun zusammen mit den Lagerelementen 16, 25 in den Federn 17, 26 frei schwingen, wie es für eine genaue Messung der Unwuchten des Rotors 6 erforderlich ist.After tightening the
Alternativ kann das Einsetzen und Halten der Turbolader-Rumpfgruppe 4 beim Spannen mittels eines positionsgenau steuerbaren Handhabungsgreifers erfolgen, der das Mittelgehäuse greift, einsetzt und in Position hält. Nach Beendigung des Spannvorgangs wird der Handhabungsgreifer geöffnet und vom Mittelgehäuse entfernt.Alternatively, the insertion and holding of the
Zur Messung einer Unwucht des Rotors 6 wird das Turbinenrad 7 mit Druckluft angetrieben und der Rotor 6 bis auf eine im Wesentlichen seiner normalen Arbeitsgeschwindigkeit entsprechenden Drehzahl beschleunigt. Zur Vermeidung von Blasgeräuschen kann am Turbinengehäuse 1 eine flexible Dichtung angebracht sein, die sich dichtend an das Hitzeschutzschild anlegt.To measure an imbalance of the rotor 6, the
Durch eine vorhandene Unwucht des beschleunigten Rotors 6 werden in die schwingende Masse aus Turbolader-Rumpfgruppe 4 und Lagerelementen 16, 25 Schwingungen induziert, die mit Hilfe des Schwingungsaufnehmers 31 bei verschiedenen Drehzahlen gemessen werden. Gleichzeitig wird durch einen Drehwinkelgeber die jeweilige Phasenlage der gemessenen Schwingungen in Bezug auf den Rotor 6 bestimmt. Aus den gemessenen Werten wird dann mit Hilfe eines elektronische Rechners Winkellage und Größe der auszugleichenden Unwucht berechnet.By an existing imbalance of the accelerated rotor 6 vibrations are induced in the oscillating mass of
