Description

Bei Schleifringsätzen für elektrische Maschinen od. dgl. «-erden meist die Schleifringe unter Zwischenlage von Isolierbaustoff auf eine metallene Nabe aufgebracht. Das Zusammensetzen dieser Schleifringkörp-er ist verhältnismäßig umständlich. .euch ist es bekannt, die Nabe der Schleifringe aus Isoliermasse zu pressen und dabei gleichzeitig die Schleifringe mit einzubetten. Ein solches Verfahren erfordert aber sehr hohe Preßdrücke und deshalb größere Pressen.In slip ring sets for electrical machines or the like «-grounds mostly the slip rings with the interposition of insulating material on a metal hub upset. The assembly of this slip ring body is relatively cumbersome. .euch it is known to press the hub of the slip rings from insulating compound and embed the slip rings at the same time. Such a procedure requires but very high pressing pressures and therefore larger presses.

Erfindungsgemäß werden diese Mängel dadurch beseitigt, daß die Schleifringe vorzugsweise zusammen mit ihren Zuleitungen auf und in einem Nabenkörper aus Isolierbaustoff, insbesondere aus keramischem Baustoff, eingespritzt oder -gegossen werden. Am besten wird nur der radial innenliegende Teil des Schleifrings gespritzt, während der die Schleiffläche bildende äußere Teil aus aufgeschrumpften, -gelöteten oder -galvanisierten Ringen besteht.According to the invention, these shortcomings are eliminated in that the slip rings preferably together with their supply lines on and in a hub body made of insulating material, in particular made of ceramic building material, are injected or poured. Preferably only the radially inner part of the slip ring is injected, during which the Outer part that forms the grinding surface and is made of shrunk, soldered or galvanized Wrestling.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Ein keramischer Isolierkörper i hat Ringnuten 2, die mit an der Stirnseite 4 ausmündenden Kanälen im Innern des Körpers i verbunden sind. In die einzelnen Nuten 2 mündende Kanäle sind gegeneinander um i2o' versetzt. In einer geschlossenen Form werden die Nuten 2 und die Kanäle 3 beispielsweise mit Aluminiumspritzguß vollgespritzt, und zwar derart, @daß die aufgespritzten Ringe 2o über die Nutenränder vorstehen und die die Kanäle 3 ausfüllenden Gußteile an den Stirnseiten Anschlußfahnen 5 bilden. Auf die Ringe 2o «-erden Stahlringe 6 aufgeschrumpft.A ceramic insulating body i has annular grooves 2, which are also on the end face 4 outflowing channels inside the body i are connected. In the individual Grooves 2 opening channels are offset from one another by i2o '. In a closed Shape, the grooves 2 and the channels 3 are injected, for example, with aluminum injection molding, in such a way that the sprayed-on rings protrude 2o over the edges of the groove and the cast parts filling the channels 3 form connecting lugs 5 on the end faces. Steel rings 6 are shrunk onto the rings 2o ″.

Die Erfindung bietet den Vorteil, das in einfacher Weise Schleifringkörper mit geringem Baustoffaufwand hergestellt werden können, die sich praktisch wie: einstückige Körper verhalten.The invention offers the advantage that the slip ring body in a simple manner can be produced with little building material expenditure, which are practically like: one-piece body behave.
