Description
Verfahren zum Einlegen von Formspulen in Nuten elektrischer Diaschinen und Apparate mittels Aufschneidens der Spulenköpfe. Um Spulen von elektrischen Maschinen oder Apparaten, die auf der Form hergestellt und fertig isoliert sind, in die Nuten einlegen zu können, hat man die Spulen vor dem Einsetzen in die Nuten aufgeschnitten und die einzelnen Leiter dann wieder miteinander verbunden, indern man sie miteinander verlötet oder verschweißt hat. Bei diesem Verfahren ist -es zuweilen schwierig, die Leiterenden an den Schnittstellen leicht und genau aneinanderzubringen, insbesondere wenn sich bei der Einarbeitung der iVTuten in das Eisen Unterschiede in der Entfernung der Nuten voneinander ergeben. Um nun die Wiedervereinigung der einzelnen Leiter zu erleichtern, sollen nach der Erfindung beim Aufschneiden aus den Leitern Stücke herausgeschnitten werden. Diese Stücke werden dann bei der Wiedervereinigung der Leiter nacheinander wieder eingesetzt, oder sie werden durch besser passende Stücke ersetzt. Bei diesem Verfahren kann man bequemer an die Schnittstellen gelangen als beün einfachen Aufschneiden. Außerdem können die Leiter die Lage, die sie beim Einlegen eingenommen haben, beibehalten.Method for inserting preformed coils into slots in electric slide machines and apparatus by cutting the coil ends. To coils of electrical machines or devices that are manufactured on the mold and ready-insulated into the grooves To be able to insert, you have cut the coils open before inserting them into the grooves and the individual conductors are then connected to one another again by inducing them to one another soldered or welded. With this procedure it is sometimes difficult to bring the conductor ends together easily and precisely at the interfaces, in particular if there are differences in distance during the incorporation of the iVTuten into the iron of the grooves result from each other. To now the reunification of the individual leaders To facilitate, according to the invention, pieces are to be cut from the conductors be cut out. These pieces will then be used at the reunion of the Ladders reinserted one at a time, or they are replaced by better-fitting pieces replaced. With this method, the interfaces can be accessed more easily than with simple slicing. In addition, the ladder can change the position that it is when it is inserted have taken, retained.
Ein Beispiel für das Verfahren nach der Erfindung ist in der Zeichnung in Abb. z und 2 veranschaulicht. Abb. r zeigt zwei Teile n und b einer Formspule, die durch Aufschneiden der Spule an zwei Stellen entstanden sind. An den Schnittstellen sind Leiterstücke entfernt. Abb.2 zeigt einen Spulenkopf nach dem Einlegen. Die Lücken an den Schnittstellen sind durch die ausgeschnittenen Stücke oder besser passende Stücke wieder gefüllt.An example of the method according to the invention is illustrated in the drawing in Figs. Fig. R shows two parts n and b of a preformed coil that were created by cutting the coil open in two places. At the interfaces, pieces of conductor have been removed. Fig.2 shows a coil head after it has been inserted. The gaps at the interfaces are filled again by the cut-out pieces or better fitting pieces.
Die Abb. r und 2 zeigen gleichzeitig eine besonders zweckmäßige, für einfaches Aufschneiden bereits bekannte Ausführungsform der Erfindung, insofern die Schnittstellen der überenanderliegenden Windungen gegeneinander versetzt sind. Hierdurch wird die Arbeit beim Zusammenfügen wesentlich erleichtert; außerdem werden Verdickungen, die beim Zusammenlöten an den Schnittstellen entstehen können, in mehrere Ebenen gelegt, so daß der äußere Querschnitt der Spule an der Stirnseite nicht an einer Stelle des Spulenkopfes ungebührlich verstärkt wird. -Anstait durch Aufschneiden an zwei Steller. jedes Leiters aus diesem einfach ein Stück von der Breite des Leiters herauszuschneiden, kann man auch Formstücke aus dieser. entfernen und wieder einsetzen oder durch andere Formstücke ersetzen. Abb.3 bis g veranschaulichen dieses Verfahren. Hierbei wird das Zusammenpassen der Leiter insofern erleichtert, als die aufgeschnittenen Leiterenden gegen Verschiebung in der Querrichtung gesichert, sind.The Fig. R and 2 show at the same time a particularly useful, for simply cutting open already known embodiment of the invention, insofar the interfaces of the overlapping turns are offset from one another. This makes the assembly work much easier; also be Thickenings that can occur at the interfaces when soldering together, in several Layers laid out so that the outer cross-section of the coil does not touch the face one point of the coil head is unduly reinforced. - Instead of cutting it open to two places. each ladder from this is simply a piece the width of the ladder You can also cut out fittings from this. remove and reinsert or replace with other fittings. Fig. 3 to g illustrate this procedure. This makes it easier for the conductors to fit together as they are cut open The ends of the conductors are secured against displacement in the transverse direction.
Besonders vorteilhaft ist es, die Schnittstellen, wie in Abb. io gezeigt, abzuschrägen, da hierdurch die Flächen für die Wiedervereinigung vergrößert werden.It is particularly advantageous to have the interfaces, as shown in Fig. bevel, as this increases the areas for reunification.
