" Bürstenhalterung ""Brush holder"
Französische Priorität vom 23. April 19 6 5 aus der französischen Patentschrift Nr« 14· 405French priority of April 23, 19 6 5 from French patent specification No. «14 · 405
Die Erfindung betrifft eine Vorrichtung zur Halterung von insbesondere zweiteiligen Kollektorbürsten in
Bürstenhaltern mit einer Federbandrolle als Andrückorgan und einer Metallplatte, die zwischen der Federbandrolle
und der Bürste liegt und diese auf der Oberseite bedeckt.The invention relates to a device for holding, in particular, two-part collector brushes in
Brush holders with a spring band roller as a pressure element and a metal plate which lies between the spring band roller and the brush and covers it on the top.

Bei einer derartigen Bürstenhalterung tritt das Problem auf, daß an der Stelle, wo die Feder mit der Metallplatte in Berührung steht, ein baldiger Verschleiß auftritt» Dieser Verschleiß hat mechanischen Ursprung, und außerdem kann eine elektrische Korrosion auftreten, wenn die Federbandrolle nicht isoliert ist.With such a brush holder, the problem arises that at the point where the spring with the metal plate is in contact, wear and tear will occur soon »This wear has a mechanical origin, and electrical corrosion can also occur if the spring ribbon roll is not insulated.
Die Erfindung hat sich die Aufgabe gestellt, den Verschleiß und die Korrosion der Feder, die mit der Metallplatte in Berührung steht, auszuschalten. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Metallplatte wenigstens an der Berührungsfläche zwischen Platte und Federbandrolle mit einem Isolierüberzug versehen ist, welcher gegenüber der Feder einen niedrigen Reibungskoeffizienten besitzt»The invention has the task of reducing the wear and tear and corrosion of the spring that is attached to the metal plate is in contact, turn off. This object is achieved according to the invention in that the metal plate is provided with an insulating coating at least on the contact surface between the plate and the spring tape roll, which has a low coefficient of friction compared to the spring »
Zu diesem Zweck eignen sich verschiedene Materialien, z.B. Polytetrafluoräthylen, Nylon, Epoxyharze und allgemein jedes Harz und jeder Kunststoff, Der Überzug wird entweder nach einer der üblichen Methoden direkt auf die Platte aufgebracht oder in Gestalt eines isolierenden Plättchens nach einem bekannten Verfahren innig mit der Metallplatte verbunden.Various materials are suitable for this purpose, e.g., polytetrafluoroethylene, nylon, epoxy resins and in general every resin and every plastic, the coating is applied either directly to one of the usual methods applied to the plate or in the form of an insulating plate by a known method intimately with the Metal plate connected.

Die Erfindung ist im nachstehenden anhand der Zeichnung beispielsweise erläutert:The invention is explained below with reference to the drawing, for example:
Fig. 1 ist ein Schnitt durch eine zweiteilige Bürste nach der Erfindung. Sie wird durch die beiden Bürstenhälften 1 und 2 gebildet. Die Metallplatte 3 ist an der Bürstenhälfte 1 befestigt und legt sich auch gegen die Bürstenhälfte 2 an.Fig. 1 is a section through a two-part brush according to the invention. It is held by the two halves of the brush 1 and 2 formed. The metal plate 3 is attached to the brush half 1 and also lies against it the brush half 2 on.
Der isolierende Überzug 4 verhindert, daß die Federbandrolle 5 mit der Metallplatte direkt in Kontakt kommt.The insulating cover 4 prevents the spring tape roll 5 comes into direct contact with the metal plate.
Die Figo 2 und 3 veranschaulichen zwei Ausführungsformen der Isolation,FIGS. 2 and 3 illustrate two embodiments of the insulation,
Fig, 2 zeigt eine Kunststoffummantelung, während nach Fig, 3 eine kleine isolierende Platte auf der Metallplatte befestigt ist.Fig, 2 shows a plastic sheath while after Fig, 3 a small insulating plate is attached to the metal plate.
