  Schleifring für elektrische Maschinen. 



   Die vorliegende Erfindung bezieht sich auf Schleifringe für elektrische Maschinen (Asynchronmaschinen, Synchronmaschinen   usw.). Gemäss   der Erfindung soll der Schleifring aus   Pcrlil-   gusseisen bestehen. Gerade Perlitguss hat zwei Eigenschaften, die für Schleifringe besonders wertvoll sind. Einerseits besitzt der Perlitguss einen sehr niedrigen Verschleiss bei gleitender Reibung. anderseits ist auch das Gefüge des Perlitgusses für die Stromaufnahme am Schleifring sehr günstig, da das Material relativ sehr viel Graphit enthält, der wie ein Schmiermittel wirkt. Es wird dadurch ein rasches Einlaufen der Bürste am Schleifring und ein ruhiger Lauf gewährleistet.

  Slip ring for electrical machines.



   The present invention relates to slip rings for electrical machines (asynchronous machines, synchronous machines, etc.). According to the invention, the slip ring should be made of Pcrlil- cast iron. Perlite cast has two properties that are particularly valuable for slip rings. On the one hand, perlite castings have very low wear and tear with sliding friction. on the other hand, the structure of the perlite casting is also very favorable for the power consumption on the slip ring, since the material contains a relatively large amount of graphite, which acts like a lubricant. This ensures that the brush runs in quickly on the slip ring and runs smoothly.
