KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Im Hauptpatent 272728 ist ein Kollektor für elektrische Maschinen beschrieben, bei welchem das durch überstehende Teile der Isolationsschichten verursachte Feuern der KoI-lektorbürsten vermieden wird. Das Mittel hierzu ist, zwischen Lamellen und Isolierschichten in der Nähe der Kollektoroberfläche Zwischenräume zu schaffen, in welche die überstehenden Teile der Isolierschichten unter dem Druck der Bürsten zurückweichen können, so daß den Bürsten ein geringer mechanischer Widerstand geboten wird.In the main patent 272728 a collector for electrical machines is described in which the fire of the KoI lector brushes caused by protruding parts of the insulation layers is avoided. The means for this is between lamellas and insulating layers near the collector surface To create gaps in which the protruding parts of the insulating layers are below the pressure of the brushes can recede, so that the brushes a little mechanical Resistance is offered.

In dem Hauptpatent ist eine Ausführungsart für die Herstellung dieser Zwischen-In the main patent, one embodiment for the production of these intermediate

1S räume beschrieben. Die Isolierschichten werden nicht in ihrer ganzen Stärke bis zur Oberfläche des Kollektors durchgeführt. 1 S spaces described. The entire thickness of the insulating layers is not carried through to the surface of the collector.

Gegenstand der vorliegenden Erfindung ist eine andere Art der Herstellung dieser Zwischenräume, die für bestimmte Fälle eine Verbesserung bedeutet. Die Zwischenräume werden nämlich dadurch geschaffen, daß man die Lamellen selbst nicht in der vollen Stärke des von ihnen normalerweise auszufüllenden Sektors bis* zur Oberfläche durchführt, sondern sie in der Nähe der Oberfläche mit seitlichen Aussparungen versieht. Der Vorteil gegenüber dem Ausführungsbeispiel des Hauptpatentes besteht darin, daß das Ziehen der Kupfersegmente in verschiedenen Profilformen sehr einfach ist, während es zuweilen fabrikationstechnische Schwierigkeiten bereitet, die Isolationsschichten in verschiedener Stärke herzustellen. The subject of the present invention is another way of producing these spaces, which means an improvement in certain cases. The gaps are created by the The lamellas themselves are not as thick as they normally have to be filled in Sector carries out * to the surface, but they close to the surface with lateral Provides cutouts. The advantage over the embodiment of the main patent is that the drawing of the copper segments in different profile shapes very much is simple, while it sometimes causes manufacturing difficulties, the insulation layers to produce in different strengths.

Die Fig. 1 und 2 zeigen Ausführungsbeispiele der Anordnung. Die Isolationsschicht a ist in voller Stärke bis zum Umfang des Kollektors durchgeführt; die Lamellen I erhalten jedoch Aussparungen b von rechteckigem (Fig. 1) oder annähernd dreieckigem Querschnitt (Fig. 2). Die Aussparungen können auch nur auf einer der beiden Längsseiten der Lamellen vorgesehen sein.FIGS. 1 and 2 show exemplary embodiments of the arrangement. The insulation layer a is carried out in full thickness up to the circumference of the collector; however, the lamellas I have recesses b of rectangular (FIG. 1) or approximately triangular cross-section (FIG. 2). The recesses can also only be provided on one of the two longitudinal sides of the slats.

Die Herstellung des Kollektors erfolgt auf sehr einfache Art, z. B. durch entsprechende Profilierung der Lamellen beim Walzen.The collector is made in a very simple way, e.g. B. by appropriate Profiling of the lamellas during rolling.
