Description

Die Erfindung - betrifft . Preßstofkommutatoren mit verhältnismäßig langen Segmenten, d. h. also Kommutatoren, die im Verglich zum Außendurchmesser eine große Länge haben. Blei isolchen Kommutatoren besteht die Gefahr, daß die sehr langen Segmente beim Lauf der Maschine Deformierungen erleiden, dieeinLockerwerden des Kommutatorverbärides zur Folge haben.The invention - concerns. Pressed commutators with relatively long segments, d. H. so commutators, which compared to the outside diameter have a great length. Lead isolchen commutators there is a risk that the very long segments suffer deformations when the machine is running, which become loosened of the commutator verb.

Gemäß der vorliegenden Erfindung werden die erwähnten Nachteile vermieden, wenn jedes Segment mindestens zwei auf seine Länge verheilte, in, Preßmasse eingebettete Füße aufweist. Zwischen den Segmentfüßen und dem Segmentkopf ist vorteilhaft eine durchgehende, längs einer Segmentseite verlaufende Nut (Rille) vorgesehen.According to the present invention, the disadvantages mentioned are avoided, when each segment has healed at least two along its length, embedded in molding compound Has feet. Between the segment feet and the segment head is advantageous continuous groove (groove) running along one side of the segment is provided.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the drawing.

Die A'bbild'ung zeigt einem Kömmwtator r im Längsschnitt. Daas lange Segment 2 hat, wie man aus der Zeichnung .ersieht, zwei Füße, und zwischen den Füßen und dem Segmentkopf befindet sich eine Längsnut 9. Im Bereich der Füße sind- auf die aus Metall bestehende Nabe 7 Isolierhüllen- 8 gezogen. Die Unterteile .der Segmente 2 sind eingebettet in Preßmasise 5. Außerdem sind Halteringe 3 vorgesehen, die auf der Nabe 7 sitzen und Durohtrittsöffnungen 4 für die Preßmasse '.haben.The picture shows a commuter r in a longitudinal section. That's long As you can see from the drawing, segment 2 has two feet and between the feet and the segment head is a longitudinal groove 9. In the area of the feet are open the metal hub 7 Isolierhüllen- 8 pulled. The lower parts of the segments 2 are embedded in Preßmasise 5. In addition, retaining rings 3 are provided that on the hub 7 sit and Durohrittsöffnungen 4 for the molding compound '. haben.
