Description
In dem Patent 445 971 ist ein Verfahren zum Einbringen von Formspulen in schräg zueinander stehende offene Nuten beschrieben, bei dem die Spulen an beiden Stirn-Seiten aufgeschnitten werden, darauf die beiden Hälften ohne Änderung ihrer Form in die Nuten eingebracht werden und sodann die freien Hälften der Enden miteinander wieder vereinigt werden. Dieses Verfahren bietet Schwierigkeiten, wenn mehrere Spulen mit ihren Stirnseiten nebeneinander herlaufen, wie aus der Zeichnung ersichtlich ist. Diese zeigt, in das Maschineneisen 1 eingebettet, zwei Spulen 2 und 3, die mit ihren Stirnseiten 4 und 5 nebeneinander herlaufen. Wohl kann die Spule 2, nachdem sie an den Stellen 6 und 7 auseinandergeschnitten ist und die beiden Hälften in das Eisen eingelegt sind, an den beiden Schnittstellen bequem wieder zusammengefügt werden. Wollte man aber mit der Spule 3 ebenso verfahren, so würden sich beim Zusammenfügen ihrer Enden an den Schnittstellen 6 und 7 der Spule 2 entsprechenden Schnittstellen 8 und 9 Schwierigkeiten ergeben, da die Arbeit durch die im Wege liegende Spule 2 behindert wird. Man könnte diesen Nachteil dadurch umgehen, daß man die Stirnseiten der Spule 2 von den Stirnseiten der Spule 3 genügend entfernt anordnet, so daß man die nötige Arbeitsfreiheit erhält. Dies hat aber den Nachteil, daß die Spule 3 in der Nutenrichtung erheblich verlängert wird, was einen Mehraufwand an'Material und Vergrößerung des Raumes für die Wicklung zur Folge hat. Diese Nachteile werden nach der Erfindung dadurch vermieden, daß die Spule 3 an ihren Stirnseiten in der Nähe der Ecken, wo die Stirnverbindungen der vorher eingelegten Spule 2 denen der einzulegenden Spule 3 noch nicht benachbart sind, aufgeschnitten wird. Dieses Verfahren ist in der Zeichnung durch die Schnittstellen io und ii veranschaulicht. Wie ersichtlich, laufen an diesen Stellen die Stirnseiten der Spule 2 nicht mehr neben den Stirnseiten der Spule 3 her, so daß genügend Raum zur Verfügung steht, um die beiden Hälften der Stirnseiten der Spulen schnell und gut zusammenzufügen. Um die aufgeschnittenen Enden gut und bequem verbinden zu können, werden die Spulen zweckmäßig nacheinander, beginnend mit der engsten Spule, eingelegt und an den Schnittstellen verbunden, so daß bei der Herstellung der Verbindungsstellen an den Stirnseiten der Spulen weder eine Behinderung durch die bereits vorher eingelegte engere Spule noch durch die später einzulegende weitere Spule möglich ist.In patent 445,971 there is a method for inserting preformed coils in obliquely open grooves standing to one another are described, in which the coils on both front sides are cut open, then the two halves without changing their shape in the grooves are introduced and then the free halves of the ends together again be united. This method presents difficulties when using multiple coils their end faces run side by side, as can be seen from the drawing. These shows, embedded in the machine iron 1, two coils 2 and 3, which with their end faces 4 and 5 run side by side. Well, the coil 2 after it is attached to the Points 6 and 7 are cut apart and the two halves are inserted into the iron can be easily put back together at the two interfaces. Wanted to but if you proceed in the same way with the coil 3, then when they are joined together Ends at the interfaces 6 and 7 of the coil 2 corresponding interfaces 8 and 9 Difficulties arise because the work is hindered by the coil 2 lying in the way. This disadvantage could be avoided in that the end faces of the coil 2 from the end faces of the coil 3 is arranged sufficiently far away so that the necessary Maintains freedom of work. However, this has the disadvantage that the coil 3 in the groove direction is considerably lengthened, which means additional expenditure in terms of material and magnification of space for the winding. These disadvantages are addressed according to the invention avoided by having the coil 3 at its end faces near the corners where the end connections of the previously inserted coil 2 to those of the coil 3 to be inserted are not adjacent, is cut open. This procedure is shown in the drawing illustrates interfaces io and ii. As can be seen, the Front sides of the coil 2 no longer next to the front sides of the coil 3, so that sufficient Space is available to move the two halves of the end faces of the coils quickly and put together well. In order to be able to connect the cut ends well and comfortably, the coils are useful one after the other, starting with the narrowest coil, inserted and at the interfaces connected, so that in the manufacture of the connection points on the end faces of the Coils neither a hindrance by the already inserted narrower bobbin nor is possible due to the additional coil to be inserted later.
Man kann die Spulen an einander gegenüberliegenden Ecken aufschneiden. Vorteilhafter schneidet man sie aber an schräg zu- ■ einander liegenden Ecken auf. Die beiden Teile werden dann einander gleich und handlicher. You can cut the coils at opposite corners. More advantageous however, if you cut them open at corners that are ■ slanted to one another. The two Parts then become equal to each other and more manageable.
