Description

Die Erfindung betrifft eine Kohlebürste für eine elektrische Maschine, die einen Kollektor federnd beaufschlagt.The invention relates to a carbon brush for an electric Machine that springs a collector.

Kohlebürsten für elektrische Maschinen sind bereits in großer Zahl mit vielfältigen Ausführungsformen bekannt. Grundsätzlich sind die Kohlebürsten in einer Führung, dem sogenannten Köcher, in einer Richtung radial zu dem Kollektor bewegbar angeordnet und beaufschlagen diesen federnd. Die notwendige Federkraft stellt eine Schraubenfeder zur Verfügung, welche sich fluchtend und in Relation zu dem Kollektor hinter der Kohlebürste befindet. Zumeist ist die Kohlebürste köcherseitig an einer Wandung, beispielsweise einer abgebogenen Lasche, abgestützt. Für die Stromversorgung der Kohlebürsten dienen separate Litzen, die gesondert mit einer Stromzuführung elektrisch leitend verbunden werden müssen. Die Kontaktierung der flexiblen Litzen mit der Stromzuführung ist problematisch, weil das Litzenende jeweils in aufwendiger Weise in die gewünschte Position gebracht werden muß. Dieses Verfahren ist für eine kostengünstige und daher vollautomatische Montage mit geringem Ausschußanteil nicht geeignet.Carbon brushes for electrical machines are already large Number known with various embodiments. Basically are the carbon brushes in a guide, the so-called Quiver, in a direction radial to the collector arranged movably and act resiliently on it. The a coil spring provides the necessary spring force, which are in alignment and in relation to the collector located behind the carbon brush. Mostly is the carbon brush on the quiver side on a wall, for example a bent one Tab, supported. For the power supply of the carbon brushes serve separate strands, which are separated with a Power supply must be electrically connected. The contacting of the flexible strands with the power supply is problematic because the stranded end is always more complex Be brought into the desired position got to. This procedure is inexpensive and therefore fully automatic assembly with low rejects suitable.

Zwar sind bereits federnde Arme mit endseitig befestigten Bürsten bekanntgeworden, welche auch den Strom zu der Kohlebürste transportieren, so daß die aufwendige Kontaktierung mit einer Litze entfällt. Ein wesentlicher Nachteil dieser Bürstenarme ist allerdings, daß das Ende des Armes zusammen mit der Bürste bei fortschreitendem Verschleiß quasi eine kreisbogenförmige Bewegung beschreibt, die einen schrägen Verschleiß der Kohlebürste verursacht. Ferner verändert sich im Betrieb ständig die maßgebliche, stromübertragende Kontaktfläche. Schließlich gelangen die Arme im Betrieb in Schwingungen, welche Aussetzer in der Stromzuführung nach sich ziehen können.Resilient arms are already attached at the ends Brushes have become known, which also flow to the carbon brush transport, so that the complex contact with a strand is eliminated. A major disadvantage of this Brush arms, however, is that the end of the arm is together with the brush as wear progresses, so to speak circular arc motion that describes an oblique Causes wear of the carbon brush. Furthermore, changes the relevant, current-transmitting contact surface during operation. Finally, the arms come in during operation Vibrations, which misfires in the power supply after can pull themselves.

Aufgabe der vorliegenden Erfindung ist es, eine Kohlebürste zu schaffen, die sich einfach und kostengünstig montieren läßt und andererseits die notwendige Sicherheit gegen Aussetzer in der Stromzuführung gewährleistet.The object of the present invention is a carbon brush to create that are easy and inexpensive to assemble leaves and on the other hand the necessary security against misfires guaranteed in the power supply.

Es wurde gefunden, daß diese Aufgabe mit den Merkmalen des Patentanspruches 1 gelöst wird. Von Vorteil ist, daß die Feder mit der Kohlebürste verbunden ist, so daß die Zuführung und Montage einer separaten Feder am Montageband des Motors entfällt. Weiterhin ist die Kohlebürste zuverlässig in radialer Richtung zu dem Kollektor geführt und es tritt insbesondere kein Schrägverschleiß auf.It was found that this task with the characteristics of Claim 1 is solved. The advantage is that the Spring is connected to the carbon brush, so that the feed and assembly of a separate spring on the assembly line of the Motors is eliminated. The carbon brush is also reliable led in the radial direction to the collector and it occurs in particular no inclined wear.

Eine Kohlebürste 1 dient der Stromversorgung der auf einem Rotor einer elektrischen Maschine angeordneten Wicklungen und beaufschlagt einen Kollektor 2 federnd. Jede Kohlebürste 1 ist in einer kanalartigen Führung 3 aus Führungselementen 4,5 in radialer Richtung zu dem Kollektor 2 bewegbar angeordnet. Wie Fig. 1 zeigt, ist der Körper 6 jeder Kohlebürste 1 mit einem Biegeschenkel 7 verbunden. Der Biegeschenkel 7 erstreckt sich rechtwinklig zu einer Bewegungsachse 8 der Kohlebürste 1, die sich in radialer Richtung zu dem Kollektor 2 erstreckt. Das kohlebürstenseitige Schenkelende 9 ces Biegeschenkels 7 ist biegesteif an dem Körper 6 angeordnet und greift beispielsweise formschlüssig in den Körper 6 ein. Zu diesem Zweck kann das Schenkelende 9 mit Hinterschneicungen versehen sein. Ganz generell ist der Biegeschenkel 7 zusammen mit der Kohlebürste 1 in der Führung 3 radial zu dem Kollektor 2 bewegbar und das andere Schenkelende 10 ist relativ zu der Kohlebürste 1 fest abgestützt. Beispielsweise ist das Schenkelende 10 an einem festen Arm 11 angeschweißt. Für die Funktion genügt allerdings bereits eine feste Anlage, so daß bei Auflage der Kohlebürste 1 auf dem Kollektor 2 die notwendige Federkraft vorliegt. In diesem Zusammenhang ist darauf hinzuweisen, daß der Arm 11 ein Bestandteil des durch die Führungselemente 4,5 gebildeten Köchers oder ein Bestandteil einer Halteplatte 12 sein kann. Wie die Fig. 2 und 3 ferner zeigen, ist ein elektrisches Versorgungselement 13 mit dem Schenkelende 10 elektrisch leitend verbunden. Also dient der Biegeschenkel 7 gleichzeitig der elektrischen Versorgung der Kohlebürste 1, so daß im Rahmen der mechanischen Befestigung des Schenkelendes 10 an dem Arm 11 gleichzeitig die elektrische Kontaktierung mit dem Versorgungselement 13 vorgenommen werden kann. Natürlich ist dafür zu sorgen, daß der elektrische Übergangswiderstand zwischen dem Biegeschenkel und dem Körper 6 möglichst gering ist. Die Kohlebürste 1 und der Biegeschenkel 7 bilden also eine einstückige Einheit, wobei der Biegeschenkel 7 zusätzlich elektrisch leitfähig ist und zur Stromversorgung der Kohlebürste 1 dient. Die Befestigung des Biegeschenkels 7 an dem Arm 11 erfolgt in einer kraftfreien Endstellung, die in Fig. 2 angedeutet ist und der Position der verschlissenen Kohlebürste 1 in Fig. 3 ähnelt. Grundsätzlich bekannte Mittel zum Zurückhalten der Kohlebürsten in der vorgespannten Endstellung sind in den Figuren nicht gezeichnet.A carbon brush 1 is used to power the on a Rotor of an electrical machine arranged windings and resiliently acts on a collector 2. Any carbon brush 1 is in a channel-like guide 3 made of guide elements 4,5 arranged movably in the radial direction to the collector 2. As shown in Fig. 1, the body 6 of each carbon brush 1 connected to a bending leg 7. The bending leg 7 extends at right angles to a movement axis 8 of the Carbon brush 1, which is in the radial direction to the collector 2 extends. The carbon brush side leg end 9 ces Bending leg 7 is arranged rigidly on the body 6 and, for example, positively engages in the body 6. For this purpose, the leg end 9 with undercuts be provided. The bending leg is generally 7 together with the carbon brush 1 in the guide 3 radially the collector 2 is movable and the other leg end 10 firmly supported relative to the carbon brush 1. For example the leg end 10 is welded to a fixed arm 11. However, a fixed system is sufficient for the function, so that when the carbon brush 1 is placed on the collector 2 the necessary spring force is available. In this context it should be noted that the arm 11 is part of the quiver formed by the guide elements 4,5 or a Can be part of a holding plate 12. Like FIG. 2 and Figure 3 further shows is an electrical supply element 13 electrically connected to the leg end 10. So the bending leg 7 also serves the electrical Supply of the carbon brush 1, so that within the mechanical Attaching the leg end 10 to the arm 11 at the same time the electrical contact with the supply element 13 can be made. Of course it is to ensure that the electrical contact resistance between the bending leg and the body 6 is as small as possible. The Carbon brush 1 and the bending leg 7 thus form a one-piece Unit, the bending leg 7 additionally electrically is conductive and to power the carbon brush 1 serves. The attachment of the bending leg 7 to the arm 11 takes place in a force-free end position, which is indicated in Fig. 2 and the position of the worn carbon brush 1 in Fig. 3 is similar. Fundamentally known means of restraint the carbon brushes in the prestressed end position are not shown in the figures.

Ausgehend von der in Fig. 2 dargestellten Anfangsstellung, in der der Biegeschenkel 7 größtmöglich ausgelenkt ist und der Körper 6 seine unverschlissene Ausgangslänge aufweist, nähert sich der Biegeschenkel 7 bei fortschreitendem Verschleiß des Körpers 6 der in Fig. 3 gezeichneten kraftfreien Endstellung an. In dieser kraftfreien Endstellung befindet sich der Biegeschenkel 7 rechtwinklig zu der Bewegungsachse 8.Starting from the initial position shown in Fig. 2, in which the bending leg 7 is deflected as much as possible and the body 6 has its unsworn initial length, the bending leg 7 approaches as wear progresses of the body 6 of the force-free drawn in Fig. 3 End position. In this non-energized end position the bending leg 7 is perpendicular to the axis of movement 8th.

Es bleibt nachzutragen, daß eine Elastizität des Biegeschenkels 7 in dessen Längsrichtung 14 das Rückfederungsverhalten und dadurch die Federwirkung verstärkt. Daraus folgt, daß der Beigeschenkel 7 auch mit einem als Zug-Druckfeder wirkenden Bereich kombiniert sein kann. Von Vorteil ist es ferner, wenn der Werkstoff des Biegeschenkels neben einem guten Federungsverhalten auch ein gutes elektrisches Leitverhalten gewährleistet, so daß geringe elektrische Verluste auftreten.It remains to be noted that the elasticity of the bending leg 7 in its longitudinal direction 14 the springback behavior and thereby increases the spring effect. It follows that the leg 7 also with a acting as a tension-compression spring Area can be combined. It is also an advantage if the material of the bending leg is next to a good one Suspension behavior also good electrical conductivity guaranteed so that low electrical losses occur.

Die Herstellung der Kohlebürste 1 geschieht wie folgt. Zunächst wird eine bestimmte Menge Graphitwerkstoff für den Körper 6 portioniert und in eine Form eingefüllt. In der Form befindet sich bereits der Biegeschenkel 7 als Einlegeteil oder es wird in einem zweiten Arbeitsschritt der Biegeschenkel in die Form eingesetzt. Sodann erfolgt das Pressen des Körpers unter hohem Druck und gegebenenfalls erhöhter Temperatur. Dem schließt sich eine Wärmebehandlung der gesamten Kohlebürste 1, das Sintern bei etwa 450 °C an. Schließlich wird die Bürste auf Maß gearbeitet und ggf. ein Schleifradius angebracht.The carbon brush 1 is produced as follows. First is a certain amount of graphite material for the Body 6 portioned and filled into a mold. In the The bending leg 7 is already in the form of an insert or in a second step it becomes the bending leg used in the form. Then the pressing takes place of the body under high pressure and possibly increased Temperature. This is followed by a heat treatment of the entire carbon brush 1, the sintering at about 450 ° C. Finally, the brush is made to measure and, if necessary, a Grinding radius attached.
