Description

Einrichtung zur Erzielung eines ruhigen Laufens von Kohlebürsten auf rauhen Kollektoren elektrischer Maschinen. Kollektormaschinen neigen häufig aus dem Grunde zu Bürstenfeuer, weil einzelne Lamellen des Kollektors oder öfter noch Isolationszwischenlagen zwischen den Lamellen gegenüber den benachbarten Teilen um ein geringes, kaum merkhares Maß hervortreten. Dadurch wird. time plötzliche mechanische Bewegung oder Erschütterung der Bürsten und damit eine oft 'beträchtliche Widerstandsänderung ihrer Berührungsflächen hervorgerufen.Device to achieve a smooth running of carbon brushes rough collectors of electrical machines. Collector machines often tend to the reason for brush fire, because individual slats of the collector or more often Isolation layers between the lamellas compared to the neighboring parts to stand out by a small, barely noticeable degree. This will. time sudden mechanical movement or vibration of the brushes and thus often a considerable amount Change in resistance of their contact surfaces caused.

Uni dies zu vermeiden und ein ruhigeres Laufen der Bürsten auf dem Kollektor zu erzielen, werden die Bürsten eines Trägers nicht wie bisher parallel zur Richtung der Lamellen, sondern in bekannter Weise etwas schräg dazu, angeordnet und so gegeneinander versetzt, -Kloß sie nicht ,gleichzeitig, sondern nacheinander auf dieselbe Lamelle auflaufen.Uni to avoid this and a smoother running of the brushes on the To achieve collector, the brushes of a carrier are not parallel as before to the direction of the slats, but somewhat obliquely to it in a known manner and so offset against each other, - they did not clump simultaneously, but one after the other run onto the same lamella.

In der Zeichnung sind zwei Ausführungsformen der Erfindung schematisch dargestellt. Man kann entweder gemäß Abb. i jede Bürste einer Stromabnalunestelle schräg stellen derart, daß jede Bürste b um. einen kleinen Feldwinkel gegen die vorhergehende, versetzt ist, oder man kann gemäß Abb. 2 mehrere oder alle ndbeneinanderliegenden Bürsten einer Stromabnahmestelle zusammen schräg stellen derart, daß ihre Kanten in einer Linie liegen. Im ersteren Fall müßten die einzelnen Bürstenhaltex entsprechend schräg gestellt oder mit schräg Zu dein Lamellen liegenden Durchtrittsöffnungen oder Führungsflächen für die Bürsten versehen sein. Zugleich könnte -die Richtung der Achse des Bürstenbolzens von der Richtung der Lamellen abweichend ausgeführt werden.Two embodiments of the invention are shown schematically in the drawing shown. You can either use any brush of a Stromabnalunstelle as shown in Fig set obliquely so that each brush b around. a small field angle against the previous, is offset, or one can, as shown in Fig. 2, several or all of the adjacent Brushes a power take-off point together at an angle such that their edges lie in a line. In the former case, the individual brush holders would have to be accordingly inclined or with inclined openings to the slats or guide surfaces for the brushes. At the same time, the direction could be the axis of the brush pin is carried out differently from the direction of the slats will.

Statt die Bürsten schräg bzw. windschief zurr Maschinenachse zu stellen, kann man auch umgekehrt,die Bürsten parallel lassen und die Lamellen des Kollektoxs windschief zur Achse anordnen.Instead of placing the brushes at an angle to the machine axis, you can also vice versa, leave the brushes parallel and the slats of the Kollektox Arrange skewed to the axis.
