Description

Die Erfindung betrifft einen für elektrische Maschinen und Geräte bestimmten Schleifringkörper, bestehend aus Kohleschleifringen, die in Preßmasse eingebettet sind.The invention relates to a slip ring body intended for electrical machines and devices, consisting of carbon slip rings embedded in molding compound.

Die bekannten Schleifringkörper für elektrische Maschinen bestehen aus leitenden Werkstoffen, insbesondere aus Kupfer. Der große Aufwand an hochwertigen Metallen macht die Schleifringe teuer und erhöht die Herstellungskosten der elektrischen ίο Maschinen. Es sind bereits Versuche gemacht worden, diesem Übelstand zu begegnen, indem man an Stelle von metallenen Schleifringkörpern Schleifringkörper aus Kohle verwendete. Die Verwendung von Schleifringkörpern aus Kohle stieß jedoch auf Schwierigkeiten, weil unerwünscht hohe Stromübergangswiderstände auftraten, die den Stromanschluß in unerwünschter Weise verschlechterten und unwirtschaftlich machten.The known slip ring bodies for electrical machines consist of conductive materials, in particular made of copper. The large amount of high quality metals makes the slip rings expensive and increases the manufacturing costs of the electrical ίο machines. Attempts have already been made To counteract this disadvantage by using slip ring assemblies instead of metal slip ring assemblies used from coal. The use of slip rings made of carbon came across, however Difficulties because undesirably high current transfer resistances occurred that the power connection undesirably deteriorated and made uneconomical.

Gemäß der Erfindung wird diesen Schwierigao keiten dadurch begegnet, daß man den Kohleschleifringen den Stromanschluß vermittelnde Metallbeilagen zuordnet, die mit den Kohleschleifringen verankert sind.According to the invention, these difficulties are met by the fact that the slip rings are made of carbon the power connection mediating metal shims assigned to the carbon slip rings are anchored.

In der Zeichnung sind einige Ausführungsbeispiele dargestellt.Some exemplary embodiments are shown in the drawing.

Fig. ι zeigt eine Ansicht eines Schleifringkörpers, teilweise im Schnitt,Fig. Ι shows a view of a slip ring body, partly in section,

Fig. 2 eine Draufsicht auf eine Metallbeilage,Fig. 2 is a plan view of a metal insert,

Fig. 3 eine Seitenansicht auf eine Metallbeilage mit abgebogener Stromanschlußfahne, die an einem geschnittenen Kohlering befestigt ist;Fig. 3 is a side view of a metal insert with a bent power connection lug, which is attached to a cut coal ring is attached;

Fig. 4 und 5 zeigen andere Befestigungsweisen.Figures 4 and 5 show other ways of attachment.

Wie aus Fig. 1 ersichtlich, besteht der Schleifringkörper ι aus den Kohleschleifringen 2, 3 und 4, die in die Freßmasse 5 eingebettet sind. Bei 6 ist eine Metallbeilage angedeutet, die an dem Kohleschleifring 4 befestigt ist und mittels der Stromanschlußfahne 7 an einen Stromkreis angeschlossen ist. Die Stromanschlußfahne 7 besteht mit der Metallbeilage 6, wie aus Fig. 2 ersichtlich, aus einem Stück. An den Stellen 8 ist die Metallbeilage, wie Fig. 3 zeigt, mit im Kohleschleifring 2 angeordneten Stiften verschweißt, gemäß Fig. 4 mittels Niete 9 mit dem Kohleschleifring verbunden ♦5 oder, wie Fig. 5 zeigt, über im Kohleschleifring eingestampfte Stifte 10 befestigt.As can be seen from Fig. 1, there is the slip ring body ι from the carbon slip rings 2, 3 and 4, which are embedded in the eating mass 5. At 6 is indicated a metal insert which is attached to the carbon slip ring 4 and by means of the power connection lug 7 is connected to a circuit. The power connection lug 7 consists of the Metal shim 6, as can be seen from FIG. 2, in one piece. At points 8 is the metal shim, as FIG. 3 shows, welded to pins arranged in the carbon slip ring 2, according to FIG. 4 by means of Rivets 9 connected to the carbon slip ring ♦ 5 or, as Fig. 5 shows, rammed into the carbon slip ring Pins 10 attached.

Der schlechten Leitfähigkeit der Kohle wegen wurden die Stromanschlüsse besonders sorgfältig ausgebildet. Erfindungsgemäß ist für jeden Schleifring ein gut leitendes Metallringsegment mit entsprechenden Kontaktverbindern vorgesehen. Diese Segmente werden an den Kohlering durch Anschweißen oder Anlöten an eingestampfte Kontakte oder durch unmittelbare Nietung an die Kohle mit dieser verbunden. Es empfiehlt sich, wie die Ausführungsbeispiele zeigen, mindestens drei Kontaktstellen vorzusehen, um im Schleifring eine günstige Stromverteilung zu gewährleisten. Die Schleifringe selbst werden in geeigneten Abständen voneinander angeordnet und in bekannter Weise mit Preßmasse umspritzt.Due to the poor conductivity of the coal, the power connections were particularly careful educated. According to the invention there is a highly conductive metal ring segment with a corresponding one for each slip ring Contact connectors provided. These segments are welded to the carbon ring or soldering to rammed contacts or by riveting directly to the carbon this connected. It is recommended, like the exemplary embodiments show to provide at least three contact points in order to have a favorable one in the slip ring Ensure power distribution. The slip rings themselves are spaced appropriately from each other arranged and encapsulated in a known manner with molding compound.

Die neuen Schleifringe zeichnen sich gegenüber den bekannten durch ausgezeichnete Stromleitfähigkeit und hohe Betriebssicherheit bei Einsparung wertvoller Metalle aus. Die neuen Schleifringe eignen sich für Schleifringsysteme aller Art, also nicht nur für elektrische Maschinen, sondern auch für elektrische Geräte und Apparate der verschiedensten Art.The new slip rings are distinguished from the known ones by their excellent electrical conductivity and high operational reliability while saving valuable metals. The new slip rings are suitable for all types of slip ring systems, not just for electrical machines, but also for all kinds of electrical devices and apparatus.
