  Bürstenhalter mit Rollbandfeder für armaturlose Bürsten 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

    B.Bürstenaussparung-10--und   erforderlichenfalls eine Aussparung des   Bürstenhalters-14-ist   Platz für die Rollbandfeder geschaffen. Durch die Änderung des Verhältnisses der Durchmesser von Druckrolle und Rollbandfeder ist nunmehr das schädliche Drehmoment, wie die Zeichnungen erkennen lassen, auf einen sehr geringen Betrag vermindert worden, wie das durch den Vergleich der   Hebelarme--9--in   Fig. 2 und   Fig. 1   ohne weiteres zu erkennen ist. 



   Fig. 3 zeigt weitere Einzelheiten der Erfindung. Mit der   Druckrolle --4-- ist   ein leicht bewegliches   Kupferseil--11--verbunden.   Da dieses Seil eine Drehung der Druckrolle verursachen und dann weiterhin durch Scheuern an der Bürstenführung des Halters defekt werden könnte, kann die Rolle an der Unterseite mit   Zapfen--13--versehen   sein, die in entsprechende Aussparungen der Kohlebürste eingreifen. Ferner ist in Fig. 3 unter Bezeichnung--12--eine Buchse aus Isoliermaterial zu erkennen, die die Druckrolle gegen die Feder isoliert. Die Buchse wird zweckmässig aus einem Isolierstoff hoher Temperaturbeständigkeit hergestellt. Ausserdem soll der Gleitwiderstand gegenüber dem Material der Achse der Druckrolle möglichst gering sein. 



   Ebenfalls in Fig. 3 ist die   Ausfräsung --10-- in   der bekannten Schwalbenschwanzform erkennbar, die das Ein- und Ausbauen der Kohlebürsten bei schlecht zugänglichen Bürstenhaltern erleichtert. 



   PATENTANSPRÜCHE : 
 EMI2.1 
 dass der Durchmesser des Druckstückes kleiner als der Durchmesser der Rollbandfeder ist und die Kohlebürste eine Aussparung für die Rollbandfeder aufweist. 
 EMI2.2

  Brush holder with roll band spring for brushes without fittings
 EMI1.1
 

 <Desc / Clms Page number 2>

    B. Brush recess-10 - and, if necessary, a recess in the brush holder-14 - space is created for the roll-up spring. By changing the ratio of the diameters of the pressure roller and the roll band spring, the damaging torque has now been reduced to a very small amount, as the drawings show, as shown by comparing the lever arms - 9 - in FIG. 2 and FIG. 1 can be easily recognized.



   Fig. 3 shows further details of the invention. An easily movable copper rope - 11 - is connected to the pressure roller --4--. Since this rope could cause the pressure roller to rotate and could then continue to be defective by rubbing against the brush guide of the holder, the roller can be provided on the underside with pins - 13 - which engage in corresponding recesses in the carbon brush. Furthermore, in Fig. 3 under the designation - 12 - a bushing made of insulating material can be seen, which isolates the pressure roller from the spring. The socket is expediently made of an insulating material with a high temperature resistance. In addition, the sliding resistance to the material of the axis of the pressure roller should be as low as possible.



   Also in Fig. 3, the milled --10 - in the known dovetail shape can be seen, which facilitates the installation and removal of the carbon brushes in the case of brush holders that are difficult to access.



   PATENT CLAIMS:
 EMI2.1
 that the diameter of the pressure piece is smaller than the diameter of the coil spring and the carbon brush has a recess for the coil spring.
 EMI2.2
