  Einrichtung zur Befestigung der Stirnverbindungen von umlaufenden Wicklungen elektrischer
Maschinen. 
 EMI1.1 
 begegnet bekanntlich besonders bei schnellaufenden   Dynamomaschinen   erheblichen Schwierigkeiten. Man hat zu diesem Zwecke teils Bandagen, teils aus geeignetem Metall gegossene Kappen benutzt, aber letztere sind einerseits gegen die durch Fliehkraft hervorgerufene mechanische Beanspruchung nicht immer widerstandsfähig genug und andererseits schliessen sowohl die Kappen als auch die Bandagen die Wicklungsköpfe völlig ein und verhindern deren Abkühlung. 



   Nach der Erfindung wird den bisher empfundenen Mängeln bekannter Befestigungen dadurch abgeholfen, dass auf dem Wicklungsträger in passenden Abständen voneinander Halter angeordnet werden, die mit seitlich vorstehenden Flanschen die Wicklungsköpfe übergreifen. 



  Die   Wicklungsköpfe   liegen dabei zum grössten Teil frei, so dass die in ihnen entwickelte Wärme

   Die Befestigung der Halter für die   Wicklungsköpfe   kann in verschiedener Weise erfolgen.

   Bei der   Ausführungsform   nach Fig. 4 sind statt des ringförmigen Wicklungsträgers einzelne seitliche Arme 9 am Läuferkörper befestigt. Ober diese Arme sind Ringe 10 von T-förmigem    Quer'chnitt   gelegt, deren Flanschenseite nach aussen gekehrt ist. Keile 11 verhindern die Drehung

   In der Zeichnung sind die Halter für die Wicklungsköpfe als aus einem Stück bestehend dargestellt. Man kann aber auch, wo dies von Vorteil sein würde, die Halter aus zwei oder mehreren   Stücken   herstellen und diese durch Verschraubung, Keile oder, sonstige. im Maschinen-

Machinery.
 EMI1.1
 is known to encounter considerable difficulties, particularly with high-speed dynamo machines. For this purpose, bandages have been used, some caps cast from suitable metal, but the latter are on the one hand not always resistant enough to the mechanical stress caused by centrifugal force and on the other hand both the caps and the bandages completely enclose the winding heads and prevent them from cooling down.



   According to the invention, the previously felt deficiencies of known fastenings are remedied in that holders are arranged on the winding support at suitable distances from one another and overlap the winding heads with laterally protruding flanges.



  The winding heads are mostly exposed, so that the heat developed in them

   The holders for the winding heads can be fastened in various ways.



  With a continuous ring-shaped winding carrier, the holders are expediently screwed to the winding carrier. But you can also use wedges or other mechanical engineering

 der Exalter owe the special shape of the holder used at the corners of the winding heads. The winding support can be provided with holes or openings 8 to increase the cooling effect.



   In the embodiment according to FIG. 4, individual lateral arms 9 are attached to the rotor body instead of the ring-shaped winding support. Rings 10 of T-shaped cross-section are placed above these arms, the flange side of which is turned outward. Wedges 11 prevent rotation

   Plate, holes 16 can be provided to improve the cooling effect. In this embodiment, the holder 12 or between the winding heads 3 and the flanges. 1. 1 intermediate inserts are provided, which, moreover, can also be used with advantage in the embodiment according to FIGS.



   In the drawing, the holders for the winding heads are shown as consisting of one piece. But you can also, where this would be advantageous, make the holder from two or more pieces and these by screwing, wedges or other. in the machine

 heads are made a little longer so that their wider feet reach under the rings.
