Description
Halter für Kollektorbürsten. Bei gekühlten Babnmotoren zum Beispiel ist das Bedürfnis vorhanden, den Halter für die Kollektorbürsten in einem Gehäuse ein zuschliessen zum Schutz gegen zerstörende Anfressung der Bürstenflanke durch mit dem Lüftungsstrom in den 3,1otor eintretenden <B>o</B> "t <B>g</B> aub oder Sand. Die vorliegende Erfindung betrifft eine besonders einfache Konstruktion eines solchen Halters mit Gehäuse.
Nach beiliegender Zeichnung, die ein Aus- führungsbeispiel des Erfindungsgegenstandes im Schnitt darstellt, weist der Halter einen Kistenunterteil 1 auf mit einer Parallelfüh- rung '.> für die Bürste 3.
Der ,Kastenteil 1 wird an einem Maschinenteil (nicht gezeichnet) befestigt. Im Kastenunterteil 1 ist ferner eine an sich bekannte Vorrichtung, bestehend aus einer Klappe 4 und einer an der letzteren angreifenden Zugfeder 5 für den automa tischen Ausgleich der Abnützung der Kollek- toroberfläche 6 einerseits und der Bürste 3 auf dem Köllektor anderseits, angeordnet.
Der Kastenoberteil besteht aus einer halb- zylinderförmigen Kappe 7, zum Beispiel aus Blech oder gepresstem Isolierstoff. Die Kappe 7 ist in der Zylinderachse bei 8 am Unter teil 1 drehbar gelagert und wird mittelst des Riegels 9 in der Schliesslage (Fig. 1) gehalten. Zum Entfernen und Wiedereinsetzen der Kollektorbürsten wird die Kappe 7 nach Lösen des Riegels 9 unter den Unterteil 1 geschwenkt und die Bürstenklappe 4 zurück gestellt (Fig. 2).
Holder for collector brushes. In the case of cooled baby motors, for example, there is a need to enclose the holder for the collector brushes in a housing to protect the brush flank from being corroded by the ventilation flow entering the motor with the ventilation flow The present invention relates to a particularly simple construction of such a holder with a housing.
According to the accompanying drawing, which shows an exemplary embodiment of the subject matter of the invention in section, the holder has a box base 1 with a parallel guide for the brush 3.
The box part 1 is attached to a machine part (not shown). In the lower part of the box 1 there is also a known device consisting of a flap 4 and a tension spring 5 acting on the latter for the automatic compensation of the wear of the collector surface 6 on the one hand and the brush 3 on the collector surface on the other.
The upper part of the box consists of a semi-cylindrical cap 7, for example made of sheet metal or pressed insulating material. The cap 7 is rotatably mounted in the cylinder axis at 8 on the lower part 1 and is held in the closed position (FIG. 1) by means of the bolt 9. To remove and reinsert the collector brushes, the cap 7 is pivoted under the lower part 1 after loosening the latch 9 and the brush flap 4 is set back (FIG. 2).
