KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Den Gegenstand der Erfindung bildet ein Kollektor . für elektrische Maschinen, dessen wesentliches Merkmal in seitlichen elastischen Scheiben besteht, wodurch erreicht wird, daß die relative Ausdehnung zwischen Welle und Kollektor lamellen reibungslos vor sich geht.The subject of the invention is a collector. for electrical machines, its essential feature consists in lateral elastic discs, whereby it is achieved that the relative expansion between the shaft and the collector lamellas goes on smoothly.
In der Zeichnung ist die Erfindung beispielsweise veranschaulicht. . ■ ■The invention is illustrated by way of example in the drawing. . ■ ■
Fig. ι stellt einen Längsschnitt durch einen ίο Kollektor dar.Fig. Ι represents a longitudinal section through one ίο collector.
Fig. 2 zeigt im Schnitt eine andere Ausführungsform der Scheiben, wobei die untere Hälfte der Einfachheit'halber in der Zeichnung fortgelassen ist.Fig. 2 shows in section another embodiment of the discs, the lower half has been omitted from the drawing for the sake of simplicity.
In Fig. ι stellen α die Welle, b die Kollektorlamellen und c ■ Schrumpfringe dar. Letztere sind in der vorliegenden Ausführungsform un-• mittelbar mit den Scheiben d verbunden, die fest auf der Welle sitzen und beispielsweise etwa durch auf die Welle geschraubte Ringe e fest gegen eine Brust der Welle gepreßt werden. Der Teil der Scheiben zwischen Nabe und.In Fig. Ι α represent the shaft, b the collector lamellas and c ■ shrink rings. In the present embodiment, the latter are directly connected to the disks d , which are firmly seated on the shaft and, for example, by rings e screwed onto the shaft be pressed firmly against a chest of the shaft. The part of the washers between the hub and.
Kranz kann so dünn gemacht werden, daß er durch Erwärmung hervorgerufene Ausdehnungen der Lamellen gestattet, so daß im Gegensatz zu den bekannten Bauarten die relative Ausdehnung zwischen Welle und Kollektorlamellen reibungslos vor sich geht. Zu diesem Zwecke kann man die Scheibe auch nach Fig. 2 ausbilden. Zwischen Nabe f und Kranz g sind hier federnde Kreisringe h eingesetzt.Wreath can be made so thin that it allows expansion of the lamellae caused by heating, so that, in contrast to the known types, the relative expansion between the shaft and the collector lamellas takes place smoothly. For this purpose, the disk can also be designed according to FIG. 2. Resilient circular rings h are used here between the hub f and the ring g.
Eine gute Kühlung erzielt man durch die Anordnung von Öffnungen in der Scheibenwand, die eventuell so groß gewählt werden können, daß nur noch Speichen übrigbleiben. Bildet man diese Speichen dann noch als Ventilatorflügel aus,, so erzielt man einen außerordentlich kräftigen Luftstrom.Good cooling is achieved by arranging openings in the pane wall, which can possibly be chosen so large that only spokes remain. If you then develop these spokes as fan blades, you get an extraordinary one powerful airflow.
