Das Verfahren, Anker elektrischer Maschinen in der Weise zu bewickeln, dafs fertig gewundene Spulen auf den Ankerkern aufgesetzt werden, ist bekannt. Die vorliegende Erfindung bezweckt die Verbesserung dieses Verfahrens in der Weise, dafs das Aufbringen der einzelnen Spulen sowie die erforderliche Lagerung derselben leichter bewirkt werden kann. Dies wird bei dem Gegenstand der Erfindung dadurch erreicht,. dafs die einzelnen, fertig gewickelten Spulen in einander greifen, wie Glieder einer Kette. Hierdurch wird erreicht, dafs, nachdem eine Spule auf den Anker aufgebracht, eine zweite mit derselben verbundene Spule wesentlich leichter in der erforderlichen Weise ebenfalls befestigt und seitlich des Ankers in entsprechenden Windungen an der Ankerwelle herumgeführt werden kann.The process of winding armatures of electrical machines in such a way that they are completely wound Coils are placed on the armature core is known. The present invention The aim is to improve this process in such a way that the application the individual coils and the required storage of the same can be effected more easily can. This is achieved in the subject matter of the invention. that the individual Completely wound bobbins interlock like links in a chain. This achieves that after a coil has been applied to the armature, a second is connected to it Coil also attached much more easily and laterally in the required manner of the armature can be guided around the armature shaft in corresponding turns.
Fig. ι der beiliegenden Zeichnung veranschaulicht schaubildlich zwei derartige in einander greifende Spulen, deren Gestalt eine unregelmäfsig sechseckige ist. Diese Form der Spulen, welche die Verwendung derselben für beliebige Ankerwickelung gestattet, empfiehlt sich ganz besonders.Fig. Ι the accompanying drawing illustrates diagrammatically two such interlocking coils, the shape of which is irregular is hexagonal. This form of the coils, which allows them to be used for any armature winding, is recommended very special.
Fig. 2 der Zeichnung zeigt zwei fertig auf dem Anker angebrachte Spulen in Vorderansicht, Fig. 2 of the drawing shows two coils already attached to the armature in a front view,
Fig. 3 die endlose Kette sämmtlicher für die Bewickelung des Ankers erforderlichen Spulen.3 shows the endless chain of all the coils required for winding the armature.
Fig. 4 veranschaulicht den mit einer gewissen Anzahl von Spulen versehenen Anker in Hinteransicht. Fig. 4 illustrates the with a certain Number of coiled armatures in rear view.
In Fig. 5 wird der theilweise bewickelte Anker, vom Stromwender aus gesehen, dargestellt. In Fig. 5 the partially wound armature, seen from the commutator, is shown.
Fig. 6 ist eine Seitenansicht desselben mit herabhängender Spulenkette. .Fig. 6 is a side view of the same with the bobbin chain hanging down. .
Die nach Art einer Kette zusammenhängenden Spulen α al a-. . . an werden in der Weise mit dem Ankerkern A in Verbindung gebracht, dafs zunächst, wie hervorgehoben, die Spule a auf denselben geschoben wird. Die Befestigung dieser Spule ist zunächst nur eine vorläufige, weil die Spule erst dann endgültig befestigt werden kann, wenn die beiden mit ihr zusammenhängenden Spulen a1 und an ebenfalls befestigt sind. Nachdem a in dieser Weise in die richtige Lage gebracht und nactw dem die Seiten der Spule, entsprechend der Form der Ankerwelle sowie etwaiger mit der Welle fest verbundener Theile, umgebogen sind, wird mit der vorläufigen Befestigung der Spule a1 begonnen, welche in ganz derselben Weise bewirkt wird. So wird fortgefahren, bis die letzte Spule ihre richtige Lage erhalten hat. Dann werden zwischen die einzelnen Spulen entsprechende Isolationsstücke b eingefügt, welche übrigens auch schon vorher angebracht werden können, und zur endgültigen Befestigung senkrecht zur Achse derselben ein Faden in Spulenform umgewickelt, welcher mit entsprechenden flüssigen und später erhärtenden Isolationsmitteln getränkt wird. Schliefslich werden die Spulen mit dem Stromwender in der Weise verbunden, dafs die Spulenenden entsprechend umgebogen und mit dem Stromwender leitend in Verbindung gebracht werden. The coils α a l a- connected in the manner of a chain. . . a n are connected to the armature core A in such a way that first, as emphasized, the coil a is pushed onto it. The fastening of this coil is initially only a provisional one, because the coil can only be finally fastened when the two coils a 1 and a n associated with it are also fastened. After a has been brought into the correct position in this way and the sides of the coil, according to the shape of the armature shaft as well as any parts firmly connected to the shaft, have been bent over, the preliminary fastening of the coil a 1 is begun, which is entirely the same Way is effected. This continues until the last bobbin is in its correct position. Then appropriate insulation pieces b are inserted between the individual coils, which incidentally can also be attached beforehand, and for the final attachment a thread in coil form is wrapped perpendicular to the axis of the same, which is soaked with appropriate liquid and later hardening insulation. Finally, the coils are connected to the commutator in such a way that the coil ends are bent over and connected to the commutator in a conductive manner.
Es ist selbstverständlich, dafs an Stelle einer endlosen Kette auch eine nicht geschlossene Kette Verwendung finden kann. In diesem Falle erweist es sich jedoch als zweckmäfsig, die letzte Spule der Kette, welche thatsächlich die vorletzte des ganzen Ankers ist, mit der ersten Spule durch eine Zwischenspule zu verbinden, welche in der gewöhnlichen Weise auf den Anker aufgewickelt wird. Soll bei etwaiger Ausbesserung des Ankers eine der Spulen herausgenommen werden, so braucht dieselbe, nachdem der die Spulen nach aufsen verdeckende Faden wieder abgewickelt ist, nur an einer passenden Stelle der Ankerstirnseite durchschnitten und herausgezogen werden. Die einzelnen Spulen können überaus leicht in die gehörige Lage gebracht und auf dem Anker an den Stirnseiten desselben in zweckmäfsiger Weise derart umgebogen werden, dafs eine sehr gleichmäfsig schöne Vertheilung der einzelnen an den Seiten . des Ankers liegenden Spulenstücke erreicht wird. Aufserdem kann jede Spule vor dem Aufbringen auf den Anker fertig gewickelt werden, und ist es so möglich, allen genau den gleichen Leitungswiderstand zu geben.It goes without saying that instead of an endless chain there should also be one that is not closed Chain can be used. In this case, however, it proves to be expedient the last coil of the chain, which is actually the penultimate of the whole anchor, with the first coil through an intermediate coil to connect, which in the usual way is wound on the anchor. Should one of the Coils are taken out, so the same needs after the bobbins to the outside covering thread is unwound again, only at a suitable point on the anchor face cut through and pulled out. The individual coils can be easily inserted into the Brought appropriate position and on the anchor on the front sides of the same in expedient Be bent in such a way that a very evenly beautiful distribution of the individual parts on the sides. the armature lying coil pieces is reached. In addition, each coil can be applied to the armature ready to be wound, and it is thus possible for all of them to have exactly the same line resistance admit.
