Description

Die Erfindung betrifft einen NutverschluB für elektrische Maschinen und hat die Aufgabe, die Einbringung und die Herstellung des Verschlusses zu erleichtern und insbesondere auch den Kreis der für solche Verschlüsse verwendbaren Materialien zu erweitern.The invention relates to a slot lock for electrical machines and has the task of facilitating the introduction and manufacture of the closure and in particular the range of materials that can be used for such closures to expand.

Erfindungsgemäß wird nach dem Einlegen der Spulen, Einträufeln der Wicklung od. dgl. die Nutöffnung mit saugfähigen Bändern, Schnüren od. dgl., vorzugsweise aus anorganischem Material, wie Asbest, Glas-, Quarzwolle, ausgefüllt und hierauf die Maschinenwicklung samt der Füllung für die Nutöffnung mit Isoliermasse, Lack, härtbarem Kunstharz od. dgl. beispielsweise im Vakuum getränkt. Nach dem Erhärten ist das mit dem Tränkstoff vollgesogene Füllmaterial der Nutöffnung ein diese Öffnung vollständig verschließender widerstandsfähiger Körper, der sehr fest in der Nut haftet.According to the invention, after inserting the coils, instillation of the Winding or the like the groove opening with absorbent tapes, cords or the like, preferably made of inorganic material such as asbestos, glass, quartz wool, filled in and on top the machine winding including the filling for the slot opening with insulating compound, varnish, Curable synthetic resin or the like. Impregnated, for example, in a vacuum. After hardening the filling material of the groove opening soaked with the impregnating substance is this opening Resistant body that closes completely and is very tight in the groove adheres.

In der Zeichnung sind einige Nütformen unter Fortlassung der Wicklung dargestellt. Bei z ist in den Nutschlitz ein fester Stoff eingelegt, dessen Ebene parallel zur Längsrichtung der Nut verläuft, bei 2 sind Bänder reit senkrecht zur Nutlängsriehtung verlaufenden Ebenen eingelegt. Bei 3 sitzt in einer passenden Aussparung der Nutöffnung eine Schnur, bei q. liegen in der Nutöffnung mehrere Schnurlagen übereinander. Nach der Tränkung und nach der Erhärtung des Tränkungsmittels ergeben sich einwandfreie, dauerhafte Nutverschlüsse. Die Erfindung bietet den Vorteil, daß zum Nutverschluß beliebige Bänder, Schnüre od. dgl. ohne vorheriger Pressung oder sonstiger Verformung verwendet werden können, die sich leicht auch in sehr schmäle Nutschlitze einführen lassen. Ein Eintreiben von harten, vorgepreßten oder sonstwie vorbehandelten Nutverschlußkörpern in die Nutöffnung fällt fort. Unter Umständen lassen sich die Schnüre oder Bänder unter Spannung =in den Nutöffnungen halten, indem man z. B. um benachbarte Maschinenwickiungsteile, um das Joch oder durch Öffnungen des Maschineneisens zieht. Sie gewährleisten dann auch ein gewisses Verspannen der Wicklung in der Nut und dadurch einen festen Wicklungssitz. Nach dem Erhärten der Tränkmasse können gegebenenfalls die überstehenden Schnur- oder Bandenden entfernt werden.In the drawing there are some slot shapes with the omission of the winding shown. At z, a solid material is inserted into the slot, its plane runs parallel to the longitudinal direction of the groove, at 2 bands are riding perpendicular to the Groove lengthways inserted planes. At 3 sits in a matching recess the groove opening a cord, at q. there are several layers of cord in the groove opening on top of each other. After the impregnation and hardening of the impregnating agent result flawless, permanent slot locks. The invention offers the advantage that any tapes, cords or the like for slot closure without prior pressing or any other deformation that can be easily converted into a very Insert narrow slots. Driving in hard, pre-pressed or otherwise pretreated slot sealing bodies in the slot opening are omitted. Under Under certain circumstances, the cords or straps can be put under tension = in the slot openings hold by z. B. to neighboring machine winding parts to the yoke or pulls through openings in the machine iron. They then also guarantee a certain amount Tensioning of the winding in the groove and thus a tight winding fit. To the hardening of the impregnating mass can, if necessary, the protruding cord or Tape ends are removed.
