Description
Die Erfindung betrifft einen Kommutator.The invention relates to a commutator.
Es sind bereits -Kömmutatoren bekanntgeworden, deren Segmente zu geschlossenen kranzförmigen Körpern zusammengeschlossen sind, welche durch stirnseitig angreifende Halteringe gehalten werden. Den bekannten Kommutatoren dieser Art haftet der Mangel an, daß die Isolation zwischen den Segmenten und den Halteringen den Anforderungen der Technik vielfach nicht genügt. Die Isolationsschichten neigen dazu, unter dem Einfluß der durch den Betrieb des Kommutators bedingten Erwärmung Eigenbewegungen auszuführen, und verlieren hierbei ihre Durchschlagsicherung. . Aus diesem Grund müssen die Isolationen bei Kommutatoren stark überdimensioniert werden, so daß der Kömmutator nach Aufbau und Ausmaßen unerwünscht groß wird.-Commutators have already become known to close their segments wreath-shaped bodies are joined together, which by frontal attacking Retaining rings are held. The known commutators of this type are liable to the defect indicates that the insulation between the segments and the retaining rings meets the requirements the technology is often not enough. The insulation layers tend to be under the Influence of the heating caused by the operation of the commutator and lose their breakdown fuse. . For this reason the insulation on commutators must be greatly oversized so that the Coming mutator is undesirably large in terms of structure and dimensions.
Gemäß der Erfindung werden nun die vorerwähnten Schwierigkeiten bei Kommutatoren vermieden, wenn man die Halteringe mit Isolierschichten umkleidet, insbesondere warm umschließt, die aus Papier und Kunststoffolien gebildet sind, wobei die Kunststoffolien auf der dem Papier abgewendeten Seite jeweils einen an sich bekannten Warmkleber tragen und das Papier selbst jeweils auf der der Warmkleberschicht abgewendeten Seite. _ der Kunststoffolien aufgeklebt ist.According to the invention, the aforementioned difficulties are now Commutators avoided if the retaining rings are covered with insulating layers, in particular warm enclosures made of paper and plastic films, the plastic foils each having one on the side facing away from the paper Carry out known hot-melt adhesive and the paper itself in each case on the hot-melt adhesive layer averted side. _ the plastic film is glued on.
Die Halteringe können dabei als Druckringe oder aber als Armierungsringe ausgebildet sein.The retaining rings can be used as pressure rings or as reinforcement rings be trained.
In der Zeichnung sieht man ein Ausführungsbeispiel eines Kommutators teilweise im Schnitt, teilweise in Ansicht.The drawing shows an exemplary embodiment of a commutator partly in section, partly in view.
Die Druckringe i sowie der Gegendruckring 2 sind mit Isolierschichten 3 umkleidet und greifen gemeinsam mit diesen in die stirnseitig vorgesehenen Einkerbungen der Segmente q:. Die Isolierschichten bestehen aus Papier und Kunststoffolien, wobei die Kunststoffolien auf der dem Papier abgewendeten Seite jeweils .einen an sich bekannten Warmkleber haben. Das Papier selbst ist jeweils auf der der Warmkleberschicht abgewendeten Seite der Kunststoffolie aufgeklebt. Als Kunststofffolien eignen sich in besonderem Maß Triazetatfolien, Azetobutyratfolien,Tripropionatfolien od. dgl. Besonders wesentlich ist es, die Isolierpackung durch Warmpressen auf die Halteringe aufzubringen.The pressure rings i and the counter pressure ring 2 have insulating layers 3 and grip together with these in the notches provided on the face of the segments q :. The insulating layers consist of paper and plastic films, whereby the plastic films on the side facing away from the paper each .eine per se known hot glue. The paper itself is in each case on that of the hot-melt adhesive layer glued on the opposite side of the plastic film. As plastic films are suitable in particular triacetate films, acetobutyrate films, tripropionate films or the like. It is particularly important to hot-press the insulating packing onto the retaining rings to raise.
In dieser Weise ausgeführte Kommutatoren weisen die eingangs erwähnten Mängel nicht auf, d. h. sie sind in elektrischer Hinsicht vollkommen durchschlagsicher auch bei erschwerten Betriebsbedingungen und genügen in mechanischer Hinsicht den an sie gestellten Anforderungen in so vollkommener Weise, daß die Kommutatoren mit wesentlich höheren Drehzahlen zu laufen vermögen als bisher, ohne daß eine Lockerung des Kommutatorverbandes zu befürchten ist.Commutators designed in this way have those mentioned at the beginning Defects not on, d. H. they are completely fail-safe from an electrical point of view even under difficult operating conditions and are sufficient from a mechanical point of view Requirements placed on them in such a perfect way that the commutators with Able to run much higher speeds than before without loosening of the commutator association is to be feared.
