Description

Einrichtung zur Regelung elektrischer Papiermaschinenantriebe nach Patent 526 773 Das Hauptpatent 526 773 bezieht sich auf eine Einrichtung zur Erzielung des relativen Gleichlaufs der von je einem Elektromotor angetriebenen Abschnitte einer Arbeitsmaschine, z. B. einer Papiermaschine, bei welcher jeder Arbeitsmotor über ein Differentialgetriebe, gegebenenfalls unter Verwendung eines Zwischengetriebes mit je einem Hilfsmotor gekuppelt ist, deren Anker zum Zwecke der Synchronisierung über Schleifringe elektrisch untereinander verbunden sind. Bei dieser Einrichtung kann der Fall eintreten, daß einer der Hilfsmotoren bei abfallender Drehzahl des zugehörigen Arbeitsmotors mehr Energie aufnimmt als die übrigen. Diese Energie muß er dann den übrigen Antriebsmotoren entnehmen, so daß infolgedessen die Hilfsmotoren außer Tritt fallen.Means for controlling electrical actuators paper machine according to the main patent 526,773 526,773 driven by a respective electric motor sections relates to a device for obtaining the relative synchronous operation of a work machine, such. B. a paper machine, in which each working motor is coupled via a differential gear, optionally using an intermediate gear, each with an auxiliary motor, the armatures of which are electrically connected to one another via slip rings for the purpose of synchronization. With this device it can happen that one of the auxiliary motors absorbs more energy than the others when the speed of the associated working motor drops. He must then take this energy from the other drive motors, so that as a result, the auxiliary motors fall out of step.

Um diesen Nachteil zu vermeiden, wird erfindungsgemäß ein Energiespeicher in Form einer Synchronmaschine vorgesehen, die in an sich bekannter Weise mit einer Schwungachse versehen ist.In order to avoid this disadvantage, an energy store is used according to the invention provided in the form of a synchronous machine, which in a known manner with a Swing axis is provided.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die fremderregten Hauptmotoren b für den Antrieb der Papiermaschinenabschnitte a werden aus der Leonarddynamo c gespeist. Jeder Hauptmotor b treibt über ein regelbares Kegelscheibengetriebe e den einen Teil eines Differentialgetriebes d an, dessen anderer Teil normal mit gleicher Geschwindigkeit von dem Hilfsmotor f angetrieben wird. Die Hilfsmotoren f sind dadurch synchronisiert, daß ihre Schleifringe i miteinander verbunden sind. h ist der von dem -Differentialgetriebe beeinfiußte Regelwiderstand für die Konstanthaltung der Drehzahl der Hauptmotoren. An die Verbindungsleitungen der Schleifringe der Hilfsmotoren ist nun eine Synchronmaschine v angeschlossen, die' mit einer Schwungachse s versehen ist. Diese Synchronmaschine dient als Energiespeicher zur Speisung der Hilfsmotoren, falls einer derselben bei abnehmender Drehzahl des zugehörigen Arbeitsmotors mehr Energie aufnimmt, so daß ein Außertrittfallen der Hilfsmotoren vermieden ist.An exemplary embodiment of the invention is shown in the drawing. The separately excited main motors b for driving the paper machine sections a are fed from the Leonarddynamo c. Each main motor b drives a controllable one Conical pulley gear e to one part of a differential gear d, whose other part normally driven by the auxiliary motor f at the same speed will. The auxiliary motors f are synchronized in that their slip rings i with one another are connected. h is the variable resistance influenced by the differential gear for keeping the speed of the main motors constant. To the connecting lines a synchronous machine v is now connected to the slip rings of the auxiliary motors, which 'is provided with a swing axis s. This synchronous machine serves as an energy store to feed the auxiliary motors, if one of them with decreasing speed of the associated work engine absorbs more energy, so that falling out of step Auxiliary engines is avoided.

Die Synchronmaschine kann einen Anwurfmotor erhalten, im übrigen aber zweckmäßig freilaufend betrieben werden.The synchronous machine can have a starter motor, but otherwise can expediently be operated free-running.
