Description

Kohleschlrenfringe für elektrische Maschinen und Apparate m-it einem an ihre Innenfläche angelöteten Metallring für .die Stromableitung sind bekannt. Ferner ist es bekannt, den Metallring mit abwechselnd von seinen beiden Enden ausgehenden Längsschlitzen zu versehen. Diese Schlitze sollen bewirken, daß bei Wärmedehnungen während des Betriebes, insbesondere aber schon beim Einlöten, Beanspruchungen des Kohleringes auf ein ungefährliches Maß beschränkt werden, so daß also weder eine Sprengung des Kohleringes erfolgen kann noch beim Lötvorgang durch Dehnen und Wiederzusammenziehen Lötstellen beschädigt werden können.Carbon loop rings for electrical machines and apparatus with one Metal ring soldered to its inner surface for the discharge of current are known. It is also known to alternate the metal ring with starting from its two ends To provide longitudinal slots. These slots are intended to prevent thermal expansion during operation, but especially during soldering, stresses on the Coal rings are limited to a safe level, so that neither one The carbon ring can be burst during the soldering process by stretching and contracting it again Solder joints can be damaged.

Bei starkem Querschnitt des eingelegten Metallringes bzw. bei einem dünnen Kohle- oder Graphitring reichen aber die eben geschilderten Maßnahmen, die den Gegenstand des Patents 747 i26 bilden, noch nicht aus, um die Kohle von gefährlichen Beanspruchungen freizuhalten.With a thick cross-section of the inserted metal ring or with a thin carbon or graphite ring, however, the measures just described, which form the subject of patent 747 i26, are not yet sufficient to keep the carbon free from dangerous stresses.

Erfindungsgemäß wird daher der Metallring (vgl. das Patent 747 126) sozusagen durchgehend geschlitzt, d. h. von ihm bleiben nur einzelne mit Abstand voneinander angeordnete Bleche übrig, deren gegenseitige mechanische und elektrische Verbindung außerhalb des Kohleschleifringes gelegt wird. Beim Einlöten der einzelnen Metallbleche tritt somit, da ja kein geschlossener Metallring mehr vorhanden ist, praktisch überhaupt keine durch Dehnung oder Zusammenziehung verursachte Gefahr der Sprengung des Kohleringes mehr auf, und sowohl die Beanspruchungen der Lötstellen durch Dehnung und Wiederzusammenziehung des Metalls beim Löten als auch die von dem eingelöteten Metallkörper verursachten mechanischen Spannungen. in dem Kohlering fallen fort. Die Metallbleche ragen axial über den Köhleschleifring hinaus und werden durch einen aufzulötenden, aufzuschweißenden oder auf eine sonstige bekannte Art und Weise an ihnen zu befestigenden Metallsammelring miteinander verbunden. Die elektrische Wirkung bleibt dabei die gleiche wie beim Gegenstand des Patents 747 126.According to the invention, the metal ring (cf. patent 747 126) is slotted continuously, so to speak, ie only individual sheets of metal spaced apart from one another remain of it, the mutual mechanical and electrical connection of which is placed outside the carbon slip ring. When the individual metal sheets are soldered in, since there is no longer a closed metal ring, there is practically no risk of the carbon ring bursting caused by expansion or contraction, and the stresses on the soldering points due to expansion and re-contraction of the metal during soldering as well as the mechanical stresses caused by the soldered metal body. in the coal ring fall away. The metal sheets protrude axially beyond the Köhl slip ring and are connected to one another by a metal collecting ring to be soldered on, welded on or fastened to them in some other known manner. The electrical effect remains the same as in the subject of patent 747 126.

Die Fig. i zeigt einen Kohleschleifring i mit an seine Innenfläche angelöteten Metallblechen 2, deren Fortsätze 2f durch einen Sammelring 3 miteinander verbunden sind. Der gegenseitige Abstand a der einzelnen Bleche 2 wird nach dem :elektrischen Bedürfnis gewählt.Fig. I shows a carbon slip ring i with on its inner surface soldered metal sheets 2, the extensions 2f of which by a collecting ring 3 with one another are connected. The mutual distance a of the individual sheets 2 is after : elected electrical need.

Gemäß Fig.2 liegt der Sammelring 3 seitlich an dem Kohlering i an.According to FIG. 2, the collecting ring 3 rests laterally on the carbon ring i.
