Abstract
Description
Die Erfindung geht aus von einem Wuchtverfahren nach der Gattung des Hauptanspruchs. Es sind schon Wuchtverfahren bekannt, bei denen die in einem ersten Verfahrensschritt festgestellte Unwucht im Laufe eines zweiten Verfahrensschritts beseitigt werden soll. Dabei wird an dem die Unwucht aufweisenden Bereich des Rotors durch Fräsen, Schleifen, Bohren etc. Material abgetragen. Danach wird in einem dritten Verfahrensschritt ermittelt, ob genügend Material abgetragen worden ist bzw. ob noch weiteres Material abgetragen werden muß. Diese Prozedur muß unter Umständen mehrfach wiederholt werden bis ein befriedigendes Wuchtergebnis erreicht ist.The invention is based on a balancing method according to the genus Main claim. Balancing processes are already known in which the unbalance detected in a first step in the course a second process step is to be eliminated. Doing so at the unbalanced area of the rotor by milling, Grinding, drilling, etc. Material removed. Then in one third step determines whether enough material has been removed or whether further material has to be removed. This procedure may have to be repeated several times until a satisfactory balancing result has been achieved.
Das erfindungsgemäße Wuchtverfahren mit den kennzeichnenden Merk malen des Hauptanspruchs hat demgegenüber den Vorteil, daß der Materialabtrag in der arbeitenden Unwucht-Meßeinrichtung vorgenommen werden kann, weil die Krafteinwirkung des Laserstrahls auf den Rotor so gering ist, daß das Meßergebnis durch den Laserstrahl nicht be einflußt wird. The balancing method according to the invention with the characteristic note Painting the main claim has the advantage that the Material removal carried out in the working unbalance measuring device can be because the force of the laser beam on the rotor is so low that the measurement result by the laser beam is not is influenced.
Ein weiterer Vorteil ist darin zu sehen, daß durch den zum Meßvor gang parallelen Abtragvorgang ohne weitere, separate Verfahrens schritte schnell und kostengünstig ein hervorragendes Wuchtergebnis erzielt werden kann.Another advantage can be seen in the fact that the measuring device parallel removal process without further, separate process an excellent balancing result quickly and cost-effectively can be achieved.
Durch die in dem Unteranspruch aufgeführte Maßnahme ist eine vor teilhafte Weiterbildung des im Hauptanspruch angegebenen Wuchtver fahrens möglich. Besonders vorteilhaft ist es demnach, wenn die Materialabtragung mittels eines pulsierenden Laserstrahls vorgenom men wird, dessen Pulsfrequenz zur Drehgeschwindigkeit des umlaufen den Rotors synchron ist.Due to the measure listed in the subclaim, there is one partial further training of the Wuchtver specified in the main claim driving possible. It is therefore particularly advantageous if the Material removal by means of a pulsating laser beam men, whose pulse frequency at the speed of rotation of the the rotors is in sync.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung darge stellt und in der nachfolgenden Beschreibung näher erläutert. Die einzige zu den Anmeldungsunterlagen gehörende Figur zeigt eine schematische Darstellung eines in einer Unwucht-Meßeinrichtung be findlichen umlaufenden Rotors und eine der Meßeinrichtung zuge ordnete Laservorrichtung.An embodiment of the invention is shown in the drawing represents and explained in more detail in the following description. The only figure belonging to the application documents shows one schematic representation of be in an unbalance measuring device sensitive rotating rotor and one of the measuring device arranged laser device.
Ein in der Zeichnung dargestellter Rotor 10 ist über eine drehbar gelagerte Welle 12 in einer Unwucht-Meßeinrichtung 14 aufgenommen. Während der Rotor 10 in Richtung des Pfeiles 16 in der Unwucht-Meß einrichtung 14 umläuft, wird seine Unwucht gemessen. Der Un wucht-Meßeinrichtung 14 ist eine Laservorrichtung 18 zugeordnet, deren pulsierender Laserstrahl 20 auf eine umlaufende Mantelfläche 22 des Rotors 10 gerichtet ist. Die Pulsfrequenz des Laserstrahls 20 ist zur Drehgeschwindigkeit des umlaufenden Rotors 10 synchron. Das bedeutet, daß nach Feststellung der Unwucht über die Synchronisa tionseinrichtung der Laserstrahl 20 immer dann arbeitet, wenn der Bereich des Rotors 10 und der Lasereinrichtung 18 vorbeidreht, an welchem zuviel Material vorhanden ist. Der arbeitende Laserstrahl 20 trägt also immer dann Material am Rotor 10 ab, wenn die übergewich tige Stelle des Rotors 10 am Laserstrahl-Auftreffpunkt 24 an der Mantelfläche 22 vorbeidreht. Da die beim Abtragen des Rotormaterials auf den Rotor 10 einwirkende Kraft extrem klein ist, wird das Meß ergebnis der Unwucht-Meßeinrichtung 14 durch die arbeitende Laser vorrichtung 18 nicht beeinträchtigt, so daß mittels der Laserein richtung 18 solange am Rotor 10 Material abgetragen werden kann, bis die Meßeinrichtung 14 ein befriedigendes Wuchtergebnis registriert.A rotor 10 shown in the drawing is received in an unbalance measuring device 14 via a rotatably mounted shaft 12 . While the rotor 10 rotates in the direction of arrow 16 in the unbalance measuring device 14 , its unbalance is measured. The Un balance measuring device 14 is associated with a laser device 18 , the pulsating laser beam 20 is directed to a circumferential surface 22 of the rotor 10 . The pulse frequency of the laser beam 20 is synchronized with the rotational speed of the rotating rotor 10 . This means that after determining the imbalance via the synchronization device, the laser beam 20 always works when the area of the rotor 10 and the laser device 18 rotates past which too much material is present. The working laser beam 20 always removes material from the rotor 10 when the overweight point of the rotor 10 at the laser beam impact point 24 rotates past the lateral surface 22 . Since the force acting on the rotor 10 when removing the rotor material is extremely small, the measurement result of the unbalance measuring device 14 is not impaired by the working laser device 18 , so that material can be removed from the rotor 10 by means of the laser device 18 as long as until the measuring device 14 registers a satisfactory balancing result.
Das beschriebene Wuchtverfahren ist besonders einfach und führt zu einem einwandfreien Wuchtergebnis des Rotors, weil während des Abtragens von Material die Unwucht-Meßeinrichtung 14 den Abtragvor gang kontinuierlich überwacht. Bei entsprechender Ausgestaltung der Meßeinrichtung ist ein automatisches Auswuchten des Rotors 10 denk bar.The described balancing method is particularly simple and leads to a perfect balancing result of the rotor because the unbalance measuring device 14 continuously monitors the ablation process during the removal of material. With an appropriate design of the measuring device, an automatic balancing of the rotor 10 is conceivable.
Der Rotor 10 kann beispielsweise ein Motoranker, ein Lüfterrad oder dgl. sein. Dabei ist es denkbar, daß die Welle 12 Teil der Unwucht-Meßeinrichtung 14 ist, auf welche der Rotor 10 aufgebracht wird. Andererseits ist es auch denkbar, wenn der Rotor 10 eine entsprechende Welle aufweist, daß diese Welle in einer an der Unwucht-Meßeinrichtung 14 vorhandene Lageraufnahme eingebracht und in dieser festgehalten wird.The rotor 10 can be, for example, a motor armature, a fan wheel or the like. It is conceivable that the shaft 12 is part of the unbalance measuring device 14 , to which the rotor 10 is applied. On the other hand, it is also conceivable if the rotor 10 has a corresponding shaft that this shaft is introduced into and held in a bearing receptacle on the unbalance measuring device 14 .
Das beschriebene Verfahren eignet sich besonders dann, wenn der auszuwuchtende Rotor aus Plastoferrit, Hartferrit oder aus Kunst stoff ist.The method described is particularly suitable if the Balanced rotors made of plastoferrite, hard ferrite or art is fabric.
