Description

Schleifring für elektrische Maschinen Schleifringe für elektrische Maschinen bestehen meist aus Kupfer oder Bronze und sind gegossen. Es ist bereits bekannt, Ringe aus nichtrostendem Stahl zu verwenden, wobei diese von Rohren abgeschnitten werden.Slip ring for electrical machines slip rings for electrical machines Machines are usually made of copper or bronze and are cast. It is already known to use stainless steel rings, these being cut off from pipes will.

Die Erfindung hat die Aufgabe, die Herstellung von Schleifringen aus Stahl auf einfache und billige Weise zu ermöglichen. Erfindungsgemäß besteht der Schleifring aus gerolltem und geschweißtem Flachstahl, wobei die Schleiffläche keine Schweißzone aufweist. Erst dadurch, daß die Schleiffläche keine Schweißzone aufweist, ist die Verwendung von Schleifringen aus gerolltem Flachstahl ermöglicht. Würde man, was naheliegt, die Enden des Ringes stumpf schweißen, dann bestünde die Gefahr einer ungleichmäßigen Abnutzung, da die Schweißzone härter ist als die übrige Oberfläche. Die Ringenden können entweder an der Stoßfuge nur auf der Innenseite autogen oder elektrisch verschweißt oder durch eingeschweißte Laschen oder Tragringe miteinander verbunden sein.The invention has the task of producing slip rings Making steel possible in a simple and cheap way. According to the invention, the Slip ring made of rolled and welded flat steel, whereby the grinding surface is not Has welding zone. Only because the grinding surface has no welding zone, the use of slip rings made of rolled flat steel is possible. Would one, which is obvious, the ends of the ring butt welded, then there would be the danger uneven wear, as the weld zone is harder than the rest of the surface. The ring ends can either be autogenous or only on the inside of the butt joint Electrically welded or welded together with brackets or support rings be connected.

Die Erfindung soll an Hand der F i g. 1 bis 7 der Zeichnung näher erläutert werden. Die Figuren zeigen verschiedene Ausführungen eines Schleifringes aus gerolltem Stahl.The invention is to be based on the F i g. 1 to 7 of the drawing explained. The figures show different designs of a slip ring made of rolled steel.

Bei dem Schleifring 1 nach den F i g. 1 und 2 sind die Ringenden an der Stoßfuge 2 auf der Innenseite autogen oder elektrisch verschweißt. Auf der Außenseite ist die Stoßfuge 2 frei von Schweißmaterial. Die Stoßfuge verläuft schräg zur Ringachse. Der Schleifring könnte auch aus mehreren Teilen zusammengesetzt sein. Bei dem Schleifring 3 nach den F i g. 3 und 4 sind die Ringenden durch eine eingeschweißte Lasche 4 verbunden, so daß die Stoßfuge 5 völlig frei von Schweißmaterial bleibt. Auch in diesem Falle kann der Ring aus mehreren Teilen zusammengesetzt sein. Die Verbindungslasche kann auch als Anschlußschiene 6 ausgebildet sein (vgl. F i g. 5).In the slip ring 1 according to FIGS. 1 and 2 are the ring ends on the butt joint 2 is autogenously or electrically welded on the inside. On the outside the butt joint 2 is free of welding material. The butt joint runs obliquely to the ring axis. The slip ring could also be composed of several parts. At the slip ring 3 according to FIGS. 3 and 4 are the ring ends through a welded tab 4 connected so that the butt joint 5 remains completely free of welding material. Also in In this case, the ring can be composed of several parts. The connecting strap can also be designed as a connecting bar 6 (see FIG. 5).

An Stelle einer oder mehrerer Laschen kann auch, entsprechend F i g. 6 und 7, ein Tragring 7 verwendet werden, auf den der aus einem oder mehreren Teilen bestehende Schleifring 8 durch Heftschweißung befestigt ist. Der Tragring 7 kann aus normalem Stahl bestehen.Instead of one or more tabs, according to F i G. 6 and 7, a support ring 7 can be used on the one or more Share existing slip ring 8 is attached by tack welding. The support ring 7 can be made of normal steel.
