Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Betriebswuchten eines Abgasturboladers mit aktiver magnetischer Lagerung.The The present invention relates to a method of operating balancing an exhaust gas turbocharger with active magnetic bearing.
Abgasturbolader von Otto- und Dieselmotoren werden mit Drehzahlen bis jenseits der 250 000 U/min betrieben. Bei hohen geforderten Lebensdaueranforderungen werden die Turbolader bei harten Umgebungsbedingungen, insbesondere stark wechselnden Betriebstemperaturen eingesetzt. Daraus ergeben sich besonders hohe Anforderungen an die Lagerung der Rotorwellen von Abgasturboladern. Die sehr verbreitet eingesetzten Öllager, z. B. in Form von hydrodynamischen Gleitlagern weisen relativ hohe Verlustleistungen im hohen Drehzahlbereich auf. Ferner bedingen sie eine thermische Belastung des Motoröls, was zu einer Alterung des Motoröls und damit verbundenen häufigeren Ölwechselintervallen führt.turbocharger of petrol and diesel engines are with speeds up to beyond the Operated 250 000 U / min. For high required service life requirements The turbocharger will be in harsh environmental conditions, in particular strongly changing operating temperatures used. Result from this particularly high demands on the storage of the rotor shafts of exhaust gas turbochargers. The widely used oil storage, z. B. in the form of hydrodynamic plain bearings have relatively high Power losses in the high speed range. Further condition they create a thermal load on the engine oil, resulting in a Aging of the engine oil and associated more frequent oil change intervals leads.
Neue
Entwicklungen haben eine berührungslose Lagerung der Rotorwellen
von Abgasturboladern zum Gegenstand. Die dabei eingesetzten Magnetlager
ermöglichen die Lagerung ohne Materialkontakt mittels Magnetkraft.
Man unterscheidet hierfür im Wesentlichen passive Magnetlager,
die in der Regel anziehende oder abstoßende Permanentmagnete
aufweisen und aktive Magnetlager, die auf geregelten Elektromagneten
beruhen, sowie Kombinationen aus beiden Lagergruppen. Eine aktive
magnetische Lagerung wird beispielsweise in der
Bisherige
Ansätze zur Lösung des Problems konzentrierten
sich im Wesentlichen darauf, durch mechanisches Auswuchten die mechanischen
Fertigungstoleranzen auszugleichen und dadurch die auf das Lager
durch Unwuchten bedingten Kräfte zu begrenzen. Hierzu werden
die Einzelteile des Rotors vor dem Zusammenbau zunächst
einzeln gewuchtet. Hierbei kommen zur Bestimmung der Unwuchten verschiedene
Messverfahren zum Einsatz, z. B. Schwingungssensoren, wie in der
Eine aktive magnetische Lagerung basiert auf einem Regelkreis, der die Position des Rotors in den Lagerachsen misst und entsprechend die Ströme in den Lagermagneten so regelt, dass der Rotor in einer kontaktfreien Schwebe bleibt. Die Positionserfassung erfolgt dabei entweder über spezielle Sensoren oder über eine Auswertung der Induktivitäten der Wicklungen der Lagermagnete.A active magnetic bearing is based on a control loop that the Position of the rotor in the bearing axes measures and accordingly the Currents in the bearing magnet controls so that the rotor in a non-contact suspension remains. The position detection takes place either via special sensors or over an evaluation of the inductances of the windings of the bearing magnets.
Es ist daher Aufgabe der vorliegenden Erfindung ein Verfahren bereitzustellen, das es ermöglicht, Unwuchten am Rotor eines Abgasturboladers in einem eingebauten Zustand in einer aktiven Magnetlagerung mittels der Sensorik der Magnetlagerung festzustellen, ohne dass es erforderlich ist, den Rotorkörper in eine eigene Wuchtmaschine einzubauen.It It is therefore an object of the present invention to provide a method which allows unbalance on the rotor of an exhaust gas turbocharger in an installed state in an active magnetic storage means To establish the gauge of a magnetic bearing without it being necessary is to install the rotor body in its own balancing machine.
Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Weitere Ausgestaltungen den Unteransprüchen wiedergegeben.These The object is achieved by the in the claim 1 specified characteristics solved. Further embodiments reproduced the subclaims.
Bei dem erfindungsgemäßen Verfahren zum Betriebswuchten eines Abgasturboladers mit wenigstens einer aktiven magnetischen Lagerung eines Rotorkörpers wird zunächst eine Taumelbewegung des sich drehenden Rotorkörpers im in die Lagerung des Abgasturboladers eingebauten Zustand aus einem Positionsdetektorsignal der magnetischen Lagerung des Rotorkörpers oder einem Lageregelkreis der magnetischen Lagerung des Rotorkörpers bestimmt und dann die Masseverteilung des Rotorkörpers so geändert, dass die Taumelbewegung des Rotorkörpers reduziert wird.at the method according to the invention for operating balancing an exhaust gas turbocharger with at least one active magnetic Storage of a rotor body is initially a Tumbling motion of the rotating rotor body in the Storage of the turbocharger built-in state from a position detector signal the magnetic bearing of the rotor body or a position control loop determines the magnetic bearing of the rotor body and then the mass distribution of the rotor body changed so that the wobbling motion of the rotor body is reduced.
Die der vorliegenden Erfindung zugrunde liegenden Idee besteht darin, dass bekannte Informationen über die Position der Rotorwelle aus dem eingebauten Zustand in eine aktive magnetische Lagerung verwendet werden, so dass das Einspannen in eine zusätzliche Wuchtmaschine entfallen kann. Durch geeignete Algorithmen und eine Wickelsensorik muss der Turbolader nur kurz in seinem eigentlichen Lager eingebaut in Betrieb genommen werden, um festzustellen, ob der Rotor ausreichend gewuchtet ist oder an welchen Stellen Material zum Auswuchten abgetragen werden muss.The idea underlying the present invention is that known information about the position of the rotor shaft from the installed state in an active magnetic storage are used, so that the clamping can be omitted in an additional balancing machine. By using suitable algorithms and a winding sensor system, the turbocharger only has to be put into operation for a short time in its actual warehouse. to determine if the rotor is sufficiently balanced or where the material needs to be removed for balancing.
Der Vorteil der vorliegenden Erfindung liegt darin, dass die Positionssensorik und Lageregelung einer magnetischen Lagerung für einen Abgasturbolader zum Auswuchten der Welle verwendet werden können. Eine teure Wuchtmaschine sowie das aufwändige Ein- und Ausbauen des Prüflings in eine gesonderte Wuchtmaschine entfällt.Of the Advantage of the present invention is that the position sensors and position control of a magnetic bearing for a Exhaust gas turbocharger can be used to balance the shaft. An expensive balancing machine and the elaborate input and output Remove the specimen in a separate balancing machine eliminated.
