Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum dynamischen Messen der Unwucht des Rotors einer Turbolader-Rumpfgruppe, wobei der Rotor ein Turbinenrad, ein Verdichterrad und eine Welle umfasst, die in einem Mittelgehäuse der Turbolader-Rumpfgruppe gelagert ist.The The invention relates to a method and a device for dynamic Measuring the imbalance of the rotor of a turbocharger hull group, wherein the Rotor includes a turbine wheel, a compressor wheel and a shaft, stored in a middle housing of the turbocharger body group is.
Abgasgetriebene Turbolader haben einen Rotor, der im Betrieb mit einer sehr hohen Drehzahl von oft über 100.000 Umdrehungen pro Minute dreht und daher zur Vermeidung von Geräuschen und zu hohen Lagerbelastungen sehr genau ausgewuchtet werden muss. Der Rotor besteht in der Regel aus einer in einem Lagergehäuse gelagerten Welle, die an einem Ende ein Turbinenrad und am anderen Ende ein Verdichterrad trägt. Die Messung der Unwucht des Rotors erfolgt aus Genauigkeitsgründen in der Regel bei einer im wesentlichen der normalen Arbeitsgeschwindigkeit entsprechenden Winkelgeschwindigkeit.exhaust-driven Turbochargers have a rotor that operates at a very high speed Rotates speed of often over 100,000 revolutions per minute and therefore to avoid noise and excessive bearing loads must be balanced very precisely. The rotor is usually from a mounted in a bearing housing shaft, which is connected to a End of a turbine wheel and at the other end carries a compressor wheel. The measurement of the imbalance of the rotor is made for accuracy reasons usually at a substantially normal operating speed corresponding angular velocity.

rigidly connecting the middle housing to a compressor housing surrounding the compressor wheel, which is mounted movably on a machine bed by means of soft springs in at least two spatial directions,
Arranging a turbine housing surrounding the turbine shell on the turbine side of the central housing in a movement of the center housing and the turbine wheel in the at least two spatial directions permitting spacing thereof and securing the turbine housing to the machine bed,
Connecting the turbine housing to a source of pressurized air and accelerating the rotor by driving the turbine wheel with compressed air to a substantially normal operating speed;
Measuring the imbalance induced vibrations on the compressor housing or on the center housing while rotating the rotor at a substantially normal operating speed,
Determining the phase position of the vibrations induced by unbalance to the angular position of the rotor at the measuring speeds at which the vibrations induced by unbalance are measured,
Using the measured vibrations induced by imbalance and the phase position to determine the unbalance of the rotor to be compensated.
Das erfindungsgemäße Verfahren ermöglicht eine Messung der Unwucht eines Turboladerrotors unter betriebsähnlichen Bedingungen, d. h. bei Belastung. Dennoch ist die schwingfähige Masse vorteilhaft klein, so dass große Schwingungsamplituden erzielt werden können. Schwingungen und Resonanzen, welche die Messgenauigkeit beeinträchtigen, werden weitgehend vermieden. Das Verdichtergehäuse benötigt im Gegensatz zum Turbinengehäuse keine Anschlüsse, da die Luft aus der Atmosphäre angesaugt und in diese frei zurückströmen kann. Die Vorrichtung zur Durchführung des Verfahrens ist kostengünstig, weil nur eine Spannvorrichtung zum Festspannen des Mittelgehäuses benötigt wird. Entsprechend einfach ist auch die Handhabung beim Einsetzen oder Entnehmen der Turbolader-Rumpfgruppe.The method according to the invention makes it possible to measure the imbalance of a turbocharger rotor sector under operational conditions, ie under load. Nevertheless, the oscillatory mass is advantageously small, so that large vibration amplitudes can be achieved. Vibrations and resonances, which affect the measurement accuracy, are largely avoided. In contrast to the turbine housing, the compressor housing does not need any connections because the air can be sucked out of the atmosphere and flowed freely back into it. The device for carrying out the method is inexpensive, because only one clamping device for clamping the center housing is needed. Equally simple is the handling when inserting or removing the turbocharger fuselage group.
