Description

Befestigung von geteilten Spulenhaltern an den Läufern elektrischer Maschinen, bei denen die Einzelteile der Spulenhaiter durch Keile auseinandergehalten werden. Um bei den Läufern elektrischer Maschinen Spulenhalter in radialer Richtung einsetzen zu können, hat man die Halter geteilt. Man hat dann entweder nach dem Einsetzen der beiden Hälften zwischen beide ein Zwischenstück eingefügt und dieses durch einen Keil am Halterkopf gegen Herausschleudern gesichert, oder man hat die beiden Teile der Halter -selbst keilförmig ausgebildet und mit Ausschnitten versehen, die das Einbringen der beiden Hälften in die Läufernut ermöglichen. `Die Erfindung ergibt eine vorteilhaftere Befestigungsart als die bekannte. Sie besteht darin, daß zum Anpressen der Halterhälften an die Spulen getrennte Keile am Halterkopf und Fuß verwendet werden.Attachment of split coil holders to the rotors electrical Machines in which the individual parts of the bobbin holder are held apart by wedges will. In order to have coil holders in the radial direction of the rotors of electrical machines to be able to use, one has divided the holder. You either have after that Inserting the two halves between both an intermediate piece and inserted this secured against being thrown out by a wedge on the holder head, or you have the both parts of the holder - themselves wedge-shaped and provided with cutouts, which enable the two halves to be inserted into the runner groove. `The Invention results in a more advantageous type of fastening than the known. she consists in that separate wedges on the holder head for pressing the holder halves against the coils and foot can be used.

Die Erfindung ist durch zwei Ausführungsbeispiele in.Abb. i und 2 der Zeichnung veranschaulicht. Mit i ist das Läufereisen bezeichnet, das die Spulen 2 trägt, die durch Spulenhalter befestigt werden, die aus den beiden Teilen 3 und q bestehen. Nach der Erfindung sitzt am Halterkopf der Keil § und am Fuß ein zweiter Keil, der im Falle der Abb. i wiederum in zwei Teile 6 und 7 zerlegt ist, die gegeneinander wirken und durch Schrauben 8 zusammengehalten werden. Der Keil am Halterfuß kann aber auch als einteiliger Keil 9 aus nachgiebigem Material ausgeführt werden, wie in Abb. 2 veranschaulicht ist. Er wird dann vorteilhaft durch Hämmern z. B. mit Preßluft auf seine in radialer Richtung nach außen liegende Fläche befestigt, wobei er durch einen Winkelhebel gestützt werden kann, der in dem Nutengrund für den Spulenhalter oder in einem unter diesem entlangführenden Kanal i o gelagert wird.The invention is illustrated in two exemplary embodiments in Fig. i and 2 illustrated in the drawing. With i the runner iron is called that the coils 2 carries, which are attached by spool holder, which consists of the two parts 3 and q exist. According to the invention, the wedge § sits on the holder head and a second one on the foot Wedge, which in the case of Fig. I is again divided into two parts 6 and 7, which face each other act and are held together by screws 8. The wedge on the holder base can but can also be designed as a one-piece wedge 9 made of flexible material, such as is illustrated in fig. He is then advantageous by hammering z. B. with Compressed air attached to its surface lying outward in the radial direction, wherein it can be supported by an angle lever that is in the bottom of the groove for the bobbin holder or is stored in a channel i o running under it.

Durch die Befestigungsart nach der Er. findung ergibt sich eine außerordentlich sichere Befestigung der Spulenhalter und der Wicklung, die ein Lockern dieser Teile praktisch unmöglich macht. Außerdem gestattet sie die an sich bekannte Belüftung der Läuferzähne durch Achsialkanäle anzuwenden, da zwischen den beiden Keilteilen und den Keilen an Kopf und Fuß der Zähne erfindungsgemäß Kanäle vorhanden sind.Due to the type of attachment according to the Er. finding results in an extraordinary secure fastening of the bobbin holder and winding, which prevents loosening of these parts makes practically impossible. In addition, it allows the ventilation known per se to apply the rotor teeth through axial channels, as between the two wedge parts and channels are present according to the invention in the wedges at the head and foot of the teeth.
