Description

Bürstenhalter aus '@fÜr elektrische Maschinen Die Erfindung betrifft einen Bürstenhalter aus Blech für' elektrische Maschinen und Apparate unter Verwendung einer Kohleführung zwischen umgebogenen Lappen. Die neue Ausführung besteht darin, daß aus einer Blechtafel die Kohleführun- durch einen Druck- oder Ziehvorgang herausgearbeitet ist. Diese -@ttsfiilirtui- besit-r_t den Vorteil. daunter größter 'Materialersparnis durch einen Ziehvorgang eine allseitig geschlossene Führungshülse mit sehr hoher Festigkeit gebildet werden kann, so daß der aus Blkli hergestellte Bürstenhalter hinsichtlich seiner Stabilität der Isohleführung einem Profilhalter mit größerem Materialaufwand gleichkommt. Gegenüber den Kohleführungen aus -Nietverbänden besteht gleichfalls der Vorteil einer Materiallind Arbeitsersparnis und einer .größeren Dauerhaftigkeit, denn bei Erschütterungen lockern sich die Nietverbände leicht, und die Kohleführung weitet sich.Brush holder from '@ for electrical machines The invention relates a brush holder made of sheet metal for 'electrical machines and apparatus using a carbon guide between bent lobes. The new design consists in that the carbon guide is carved out of a sheet metal sheet by means of a pressure or drawing process is. This - @ ttsfiilirtui- has the advantage. including the greatest 'material savings through a pulling process a guide sleeve closed on all sides with a very high Strength can be formed, so that the brush holder made of Blkli with regard to its stability of the insole guide a profile holder with a larger Cost of materials equals. Compared to the carbon guides, it consists of rivet associations likewise the advantage of a material and labor saving and a larger one Durability, because the rivet bonds loosen easily in the event of vibrations, and the coal duct widens.

In der Zeichnung ist als Beispiel ein Bürstenhalter nach der Erfindung schaubildlich wiedergegeben. Aus einem Blechstück z ist die Kohleführung 2 durch einen Ziehvorgang herausg earb.eitet. Die Kohlebürste 3 wird durch eine am Bolzen 6 befestigte Feder 7 niedergedriickt. Eine tose 8 dient zum Einlöten des Bürsten- und Anschlußkabels. An Stelle dieser Öse können selbstverständlich auch ein Gewindebolzen mit -Muttern cwrler andere Anschlußm6glichkeiten treten. Die Löcher und ; am seitlichen Halterflansch «-erden zur Befestigung des Halters benutzt. Die außerhalb der Xohlefiihrung liegende Bürstenhalterausführung kann auch anders -eltalteii sein.In the drawing, a brush holder according to the invention is shown diagrammatically as an example. From a piece of sheet metal z, the carbon guide 2 is earb.eited by a drawing process. The carbon brush 3 is pressed down by a spring 7 attached to the bolt 6. A tose 8 is used to solder the brush and connection cable. Instead of this eyelet, a threaded bolt with nuts can of course also be used for other connection options. The holes and; on the lateral holder flange «-grounds used to attach the holder. The brush holder design lying outside the sole guide can also be different.
