Vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Dynamobürsten, die aus Kohle sowohl wie aus Metall bestehen und daher die guten Eigenschaften der Kohlen- und der Metallbürsten in sich vereinigen, ohne die diesen anhaftenden Übelstände aufzu-' weisen.The present invention relates to a method for producing dynamo brushes, which consist of coal as well as of metal and therefore the good properties of the coal and unite the metal brushes without the evils that are attached to them. point.
Die Herstellung von Elektrizitätsleitern in Form von Platten durch Überziehen von Stoff--The manufacture of electricity conductors in the form of plates by covering them with fabric--
ίο stücken mit einer Metallschicht auf galva-' nischem Wege oder durch Eintauchen von Asbestgewebe in geschmolzene Metallmasse ist bereits bekannt. Durch solche Verfahren kann aber ein gleichartiger Leiter, wie es bei dessen Verwendung als Dynamobürste erforderlich ist, nicht erzeugt werden, da bei dem Überziehen der Stoffstücke auf galvanischem Wege hauptsächlich die Außenfläche bekleidet wird, während beim Eintauchen in Metallmasse das Gewebe aus nicht leitendem Asbest bestehen muß.ίο pieces with a metal layer on galva- ' nisch way or by immersing asbestos fabric in molten metal mass is already known. Such a method can, however, lead to a similar leader, as is the case with whose use as a dynamo brush is required, are not generated, since in the Coating the pieces of fabric by galvanic means mainly covers the outer surface becomes, while when immersed in metal mass the fabric is made of non-conductive asbestos must exist.
Man hat auch für die Herstellung von Dynamobürsten ein Verfahren benutzt, welches darin besteht, daß poröse...Kolilenblöcke in eine Metallsalzlösung getaucht und dann erhifzt werden, wobei das Metall ausfällt und einen Überzug auf den Wänden der Poren bildet.A process has also been used for the manufacture of dynamo brushes consists in the fact that porous ... colile blocks are immersed in a metal salt solution and then heated the metal precipitates and a coating on the walls of the pores forms.
Auch hierbei kann ein durch seine ganze Masse gleichartiger Leiter nicht erzeugt werden, weil die Poren mit Metall nicht ganz ausgefüllt werden können, sondern nicht leitende Kanäle bilden, die Funkenbildung hervorrufend Auch ist schon vorgeschlagen worden, Kohlenbürsten aus verkupfertem Kohlenstaub anzufertigen. Here, too, a conductor of the same type due to its entire mass cannot be produced, because the pores cannot be completely filled with metal, but not conductive Forming channels that cause sparks. It has also been proposed to use carbon brushes to be made from copper-coated coal dust.
Nach vorliegender Erfindung wird indessen eine innigere Verbindung der einzelnen, mit einem metallischen Überzug versehenen Kohle-Teile"dadurch bewirkt, daß die genannten Teile noch verzinnt werden. Sodann werden diese, Teile durch äußeren Druck ohne Anwendung von Bindemittel zusammengepreßt und _gegebenenfalls während oder nach dem Pressen erhitzt, so daß durch das Flüssigwerden des Zinnüberzuges ein Zusammenlöten der einzelnen Teile erfolgt.According to the present invention, however, a more intimate connection between the individual, with a metallic coating provided carbon parts "thereby causes the parts mentioned to be tinned. Then these Parts pressed together by external pressure without the use of binding agents and if necessary heated during or after pressing, so that the individual soldering together by the liquidation of the tin coating Parts takes place.
Auf diese Weise gewinnt man einen von Kanaleii_und_Po.r..en..freien,..völlig gleichartigen Körper, welcher einen zusammenhängenden ''50 metallischen Leiter mit eingebetteten Kohlenkörnern bildet und nicht nur größere Leitfähigkeit und geringeren Übergangswiderstand besitzt als die oben erwähnten Leiter, sondern auch durchaus funkenfrei arbeitet und bei der Benutzung keine Kohle an dem Stromwender absetzt.In this way you get one of Kanaleii_und_Po.r..en..free, .. completely similar Body, which is a coherent ''50 metallic conductor with embedded grains of carbon forms and not only has greater conductivity and lower contact resistance than the conductors mentioned above, but also works absolutely spark-free and at the Do not use coal on the commutator.
Es ist noch zu erwähnen, daß man bereits elektrische Leiter/ sowohl aus zusammenge-' preßtem Metallpulver als auch aus einer Mi-j schung von Kohlen- und Metallpulver hergefstellt hat. Derartige Leiter verhalten sich aber in bezug auf/Funkenbildung und Abnutzung' des Stromwenders wie Metallbürsten. Das Zusammenhalten zwischen solchen aus gewohnlichen Metall- und Kohlenkörnern zu-It should also be mentioned that one already has electrical conductors / both pressed metal powder as well as from a Mi-j made of coal and metal powder. Such conductors behave, however with respect to / sparking and wear of the commutator such as metal brushes. That Holding together between those made of ordinary metal and coal grains.
sammengepreßten Körpern ist jedoch geringer, als das Zusammenhalten bei Leitern, welche nach vorliegender Erfindung hergestellt sind.compressed bodies is less than the holding together with ladders, which are made according to the present invention.
