 EMI1.1 
 
Es sind bereits verschiedene Widerstandsschweissmaschinen mit in die Elektrodenrolle eingebautem Transformator (Rolltrafo) bekannt, die eine besondere Kühlung benötigen. Die bisher hiefür verwendeten Kühlvorrichtungen sind jedoch entweder nicht genügend wirksam (z. B. normale Luftzirkulation durch Gehäuseschlitze) oder kompliziert und teuer (z. B. Wasser-oder Ölkühlung). Der Erfindungsgegenstand betrifft nun eine Verbesserung der Luftkühlung, indem die Kühlluft mittels eines in der Mitte des Rolltrafos angeordneten Ventilators zwangläufig bewegt wird. Der Antriebsmotor des Ventilators ist an einem Lagerschild des Trafos angebracht und primärseitig am Trafo angeschlossen. 



   Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung veranschaulicht, u. zw. zeigt Fig. 1 einen lotrechten Schnitt durch den Rolltrafo und Fig. 2 dessen Seitenansicht bei abgenommenen Lagerschild. 



   Der Kranz der Elektrodenrolle besteht aus zwei im geringen Abstand voneinander angeordneten, im Querschnitt winkelförmigen Ringen 2, die mit einer ihrer Schenkelflächen zueinander parallel liegen. Der so entstehende Doppelring ist mittels U-förmiger, den   Trafokern   bzw. Traforingkern 1 umfassender Laschen 3 im Abstand vom Trafokern 1 gehalten und bildet gleich die Sekundär- seite des Trafos. Zwischen den Laschen 3 sind in bekannter Weise die Primärspulen 6 auf dem Ringkern 1 des Trafos aufgesetzt, die den Strom von an einem der Lagerschilde 9 angeordneten
Schleifringen 7 erhalten. Die Lagerschilde 9 sind im Abstand vom Ringtrafo gehalten und mit diesem durch Bolzen bzw. Spannschrauben 8 verbunden. Die Lagerzapfen 5 der Lagerschilde 9 ruhen in entsprechenden, auf seitlichen   Ständern10   befindlichen Lagern.

   In der Mitte des Ringtrafos ist erfindungsgemäss ein Ventilator 4 angeordnet, dessen Antriebsmotor 11 an einem Lagerschild 9 befestigt und primärseitig am Rolltrafo angeschlossen ist. Die Wirkungsweise dieser Lüftungs-bzw. Kühleinrichtung geht aus Fig. 1 deutlich hervor, in der die Luftein-und austrittswege 12 durch Pfeile angedeutet sind.

 EMI1.1
 
Various resistance welding machines with transformers (roll transformers) built into the electrode roller are already known which require special cooling. The cooling devices previously used for this purpose are either not sufficiently effective (for example normal air circulation through housing slots) or are complicated and expensive (for example water or oil cooling). The subject matter of the invention now relates to an improvement in air cooling, in that the cooling air is forced to move by means of a fan arranged in the center of the roller transformer. The drive motor of the fan is attached to a bearing plate of the transformer and connected to the transformer on the primary side.



   An embodiment of the subject invention is illustrated in the drawing, u. Between. Fig. 1 shows a vertical section through the roll transformer and Fig. 2 shows its side view with the bearing plate removed.



   The ring of the electrode roller consists of two rings 2, which are arranged at a small distance from one another and are angular in cross-section and which are parallel to one another with one of their leg surfaces. The resulting double ring is held at a distance from the transformer core 1 by means of U-shaped tabs 3 surrounding the transformer core or transformer ring core 1 and forms the secondary side of the transformer. Between the tabs 3, the primary coils 6 are placed in a known manner on the toroidal core 1 of the transformer, which the current from arranged on one of the bearing plates 9
Slip rings 7 received. The end shields 9 are held at a distance from the ring transformer and are connected to it by bolts or tensioning screws 8. The journals 5 of the end shields 9 rest in corresponding bearings located on lateral uprights 10.

   According to the invention, a fan 4 is arranged in the middle of the ring transformer, the drive motor 11 of which is fastened to a bearing plate 9 and is connected on the primary side to the roll transformer. The operation of this ventilation or. The cooling device is shown clearly in FIG. 1, in which the air inlet and outlet paths 12 are indicated by arrows.
