Die Erfindung betrifft eine Schleifringanordnung für elektrische Maschinen, inbesondere Drehstromgeneratoren in Kraftfahrzeugen, bei welcher auf der umlaufenden Maschinenwelle mindestens ein Schleifring befestigt und zwischen der Welle und dem Schleifring eine Isolierschicht angeordnet ist.The invention relates to a slip ring assembly for electrical Machines, especially three-phase generators in motor vehicles, in which on the rotating machine shaft at least one slip ring is attached and an insulating layer is arranged between the shaft and the slip ring is.
Der Erfindung liegt die Aufgabe zugrunde, die Haftfestigkeit des Schleifrings bzw. der Schleifringe auf der Welle zu verbessern. Dazu ist vorgesehen, daß die Welle in demjenigen Bereich ihrer Länge, auf welchem der Schleifring angeordnet ist, mit einer wenigstens eine Hut aufweisenden Längsverzahnung versehen ist, die mit einer im Wirbelsinterverfahren aufgebrachten Isolierschicht bedeckt ist. In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß mit der Längsverzahnung der Welle ein Formschluß durch Imprägnierharz hergestellt ist.The object of the invention is to improve the adhesive strength of the slip ring or slip rings on the shaft to improve. For this purpose, it is provided that the shaft is in that region of its length on which the slip ring is arranged, is provided with at least one hat having longitudinal teeth, which with an im Fluidized bed process applied insulating layer covered is. In a further embodiment of the invention it is provided that with the longitudinal toothing of the shaft Positive locking is made by impregnating resin.
Als Ausführungsbeispiel der Erfindung ist nachstehend eine Schleifringanordnung mit zwei parallel zueinander auf einer Welle befestigten Kohleschleifringen beschrieben, die in der Zeichnung in einem teils in der Ansicht teils im Längsschnitt wiedergegeben ist.As an embodiment of the invention, the following is a slip ring arrangement with two parallel to each other Carbon slip rings attached to a shaft are described in the drawing in part in the view partly shown in longitudinal section.
Auf ihrem antriebsfernen Ende trägt die Ankerwelle 13 eines im übrigen nicht wiedergegebenen Drehstromgenerators eine Längsverzahnung 25s die wenigstens eine Hut 26 aufweist. In dieser ist ein Anschluß 22 der Erregerwicklung unter den beiden Kohleschleifringen 23 hindurchgeführt. Gegenüber der Welle 13 sind die Schleifringe 23 durch eine Isolierschicht 27 aus Epoxidharz isoliert, die im Wirbelsinterverfahren auf die Längsverzahnung 25 aufgebracht ist. Die Isolierschicht 27 bedeckt die Längsverzahnung 25 in einer Stärke von etwa 0,3 mm. An der Bohrungsseite der beiden Schleifringe 23 ist ebenfalls eine dünne Expoxidharzschicht im Wirbelsinterverfahren aufgebracht und in der Zeichnung bei 38 angedeutet. An jeweils einer der Stirnseiten der Kohleschleifringe ist eine dünne Kupferscheibe 31 angesintert, welche in der aus der Zeich- , nung erkennbaren Weise zum Anlöten der Wicklungsenden 22 der im übrigen nicht dargestellten Erregerwicklung des Generators dienen. Zur Erzielung eines Formschlusses sind die zwischen der beschichteten Verzahnung 25 und der Bohrungsschicht 38 verbleibenden Hohlräume unter Anwendung von Druck und Wärme mit einem in der Zeichnung nicht wiedergegebenem Imprägnierharz ausgefüllt, das nach dem Erhärten eine mitnahmefeste Verbindung zwischen den Kohlesehleifringen 23 und der Welle 2h bzw. 13 sicherstellt.On its end remote from the drive, the armature shaft 13 of a three-phase generator, which is otherwise not shown, has a longitudinal toothing 25s which has at least one hat 26. In this a connection 22 of the excitation winding is passed under the two carbon slip rings 23. Compared to the shaft 13, the slip rings 23 are insulated by an insulating layer 27 made of epoxy resin, which is applied to the longitudinal toothing 25 using the fluidized bed sintering process. The insulating layer 27 covers the longitudinal toothing 25 with a thickness of approximately 0.3 mm. A thin epoxy resin layer is also applied to the bore side of the two slip rings 23 using the fluidized bed sintering process and is indicated at 38 in the drawing. A thin copper disk 31 is sintered to one of the end faces of the carbon slip rings, which are used in the manner shown in the drawing to solder the winding ends 22 of the exciter winding of the generator, which is otherwise not shown. In order to achieve a positive fit, the cavities remaining between the coated toothing 25 and the bore layer 38 are filled with an impregnating resin, not shown in the drawing, using pressure and heat, which after hardening creates a fixed connection between the carbon slip rings 23 and the shaft 2h or 13 ensures.
