Description

Es ist bekannt, bei elektrischen Maschinen für hohe Ströme eine Einrichtung vorzusehen, die den umlaufenden Anker in eine hin und her gehende axiale Bewegung versetzt,- um zu verhindern, daß die Stromabnahmebürsten immer an denselben Stellen des Stromwenders oder der Schleifringe schleifen und dadurch an diesen Stellen Riefen hervorrufen.It is known to have a device for high currents in electrical machines provide that the rotating armature in a reciprocating axial movement offset, - to prevent the current pick-up brushes always in the same places of the commutator or the slip rings and thus scoring at these points cause.

Die Erfindung bezieht sich nun auf solche Maschinen, bei denen die axiale Bewegung des Ankers aus konstruktiven, prinzipiellen oder anderen Gründen nicht möglich ist, z. B. auf Unipolarmaschinen. Die Riefenbildung an den Schleifflächen derartiger Maschinen läßt sich erfindungsgemäß dadurch vermeiden, daß die Bürsten an einem Bürstenträger befestigt sind, der im Betrieb eine stetige hin und her gehende Bewegung quer zur Schleifrichtung ausführt.The invention now relates to such machines in which the axial movement of the armature for structural, fundamental or other reasons is not possible, e.g. B. on unipolar machines. The formation of grooves on the grinding surfaces Such machines can be avoided according to the invention in that the brushes are attached to a brush holder, which in operation is a steady back and forth Moves transversely to the grinding direction.

Ein Ausführungsbeispiel der Erfindung in Anwendung auf eine Maschine mit Planschleiffläche am Schleifring ist in der Zeichnung schematisch dargestellt. Es sei angenommen, daß der Schleifring an der Stirnseite der Maschine senkrecht zur Maschinenachse liegt. Von dem Schleifring 3 wird der Strom mittels der Bürsten 2 abgenommen, die am Umfang eines Bürstenträgers I verteilt angeordnet sein können. Die Schleifrichtung ist durch Pfeile S angedeutet und kann rechts- oder linksläufig sein, so daß die Bürstenträgerbewegung in Richtung der Pfeile J, d. h. in vertikaler Richtung, erfolgen muß, um eine Riefenbildung an den Schleifflächen zu verhindern. Zur Führung des Trägers in dieser Richtung dienen zwei an einem feststehenden Teil in geeigneter Weise gelagerte Zapfen 4 und 5, von denen dem ersteren die Druckfeder 6 zugeordnet ist. Ein an dem Zapfen 5 angreifender Exzenter 7 bewegt den Bürstenträger gegen den Federdruck, während die Rückführung durch die Rückstellkraft der Feder erfolgt. Der Antrieb des Exzenters kann zwangläufig von der Maschinenwelle aus über ein entsprechendes Vorgelege erfolgen oder durch einen besonderen Motor, der gegebenenfalls von der Hauptmaschinendrehzahl gesteuert wird. Zwei Führungen 8 am Bürstenträger, die in Backen 9 gleiten, verhindern ein Verdrehen des Bürstenträgers.An embodiment of the invention applied to a machine with flat grinding surface on the slip ring is shown schematically in the drawing. It is assumed that the slip ring is perpendicular to the face of the machine to the machine axis. From the slip ring 3 is the current by means of the brushes 2 removed, which can be arranged distributed on the circumference of a brush holder I. The direction of grinding is indicated by arrows S and can be clockwise or counterclockwise so that the brush holder movement in the direction of arrows J, i.e. H. in vertical Direction, must take place in order to prevent scoring on the grinding surfaces. Two on a fixed part serve to guide the carrier in this direction appropriately mounted pins 4 and 5, of which the former is the compression spring 6 is assigned. An eccentric 7 engaging the pin 5 moves the brush holder against the spring pressure, while the return by the restoring force of the spring he follows. The drive of the eccentric can inevitably come from the machine shaft a corresponding back gear take place or by a special motor, which, if necessary controlled by the main engine speed. Two guides 8 on the brush holder, which slide in jaws 9 prevent twisting of the brush holder.

Die Erfindung läßt sich selbstverständlich auch bei Maschinen mit Planschleiffläche am Kollektor oder mit Zylinderschleiffläche am Kollektor oder mit Zylinderschleiffläche am Schleifring verwenden.The invention can of course also be used in machines Flat grinding surface on the collector or with cylindrical grinding surface on the collector or Use with a cylindrical grinding surface on the slip ring.
