Der bekannte flüssigkeitsgekühlte umlaufende Feldmagnet für Turbogeneratoren gemäß dem Hauptpatent 578658 besitzt in zur ■Läuferachse parallelen Ebenen miteinander abwechselnd angeordnete, längs der Mantelfläche und der Stirnfläche des Läuferkörpers herumgeführte Wicklungsnuten sowie solche Kühlkanäle, welche, ähnlich den Wicklungsnuten, gleichfalls parallel zu den Mantel- und Stirnflächen des Läuferkörpers in der Form von in sich geschlossenen Ringen herumgeführt und an axiaie Zu- bzw. Ableitungskanäle der Achsstummel des Läuferkörpers angeschlossen sind. Daraus, daß hierbei die Richtung der Kühlkanäle mit jener der Wicklungsnuten immer übereinstimmt und zur wirksameren Kühlung die Kühlkanäle nicht nur an der Mantelfläche, sondern auch an den Stirnflächen überall oder überwiegend ao zwischen den Wicklungsnuten angeordnet sind, ergibt sich, daß die geschlossenen Ringsysteme der Kühlkanäle gleichfalls in untereinander und zu den Wicklungsebenen parallelen Ebenen liegen.The well-known liquid-cooled circulating Field magnet for turbo generators according to the main patent 578658 in for ■ Rotor axis parallel planes arranged alternately with one another, along the lateral surface and the end face of the rotor body and winding grooves guided around it Cooling channels, which, similar to the winding slots, are also parallel to the jacket and End faces of the rotor body guided around in the form of self-contained rings and the stub axles of the rotor body are connected to axial supply and discharge channels. From the fact that here the The direction of the cooling channels always coincides with that of the winding slots and for more effective cooling, the cooling channels not only on the outer surface, but also arranged on the end faces everywhere or predominantly ao between the winding grooves are, it follows that the closed ring systems of the cooling channels are also in planes parallel to each other and to the winding planes.
Die Kühlkanäle werden gemäß der Fig. 5 des Hauptpatentes von längs der Mantelfläche des Läufers verlaufenden Nuten gebildet, die außen durch im Querschnitt trapezförmige Abschlußleisten abgeschlossen sind. Dieser Verschluß der Nuten ist jedoch in bezug auf die Abdichtung noch nicht befriedigend.The cooling channels are according to FIG. 5 of the main patent from along the lateral surface of the rotor running grooves formed, the outside by trapezoidal in cross-section End strips are complete. However, this closure of the grooves is related to the seal is not yet satisfactory.
Die Erfindung beseitigt diesen Nachteil dadurch, daß die Abschlußleisten in ihrer ganzen Länge durch Schweißen mit dem Läuferkörper dicht verbunden werden.The invention eliminates this disadvantage in that the end strips in their be tightly connected to the rotor body by welding over the entire length.
Die Erfindung ist in drei vorteilhaften Ausführungsformen in drei Abbildungen beispielsweise veranschaulicht.The invention is shown in three advantageous embodiments in three figures, for example illustrated.
Die zwischen den Wicklungsnuten ausgebildeten schmalen und tiefen Kühlnuten 1 sind gemäß Abb. 1 durch die bekannten, im Querschnitt trapezförmigen Abschlußleisten 2 und gemäß Abb. 2 durch in die Nuten eingelassene Abschlußleisten 2 verschlossen, die in ihrer ganzen Länge mit dem Läuferkörper durch zwei Schweißnähte 3 so verbunden sind, daß ein völlig dichter Verschluß der Kühlkanäle erzielt wird.The narrow and deep cooling grooves 1 formed between the winding grooves are shown in Fig. 1 by the known, trapezoidal cross-section end strips 2 and according to Fig. 2 closed by end strips 2 embedded in the grooves, which are shown in their entire length with the rotor body by two welds 3 so connected are that a completely tight seal of the cooling channels is achieved.
Der Verschluß der Kühlnuten kann aber auch gemäß Abb. 3 durch eine einzige breitere Schweißnaht 3 je Nut bewirkt werden.The closure of the cooling grooves can also be made according to Fig. 3 by a single wider one Weld 3 can be effected per groove.
Auch gemäß Abb. 2 und 3 gewährleistet die Schweißnaht 3 längs der ganzen Nutkante selbst nach Abglätten der Nahtoberfläche noch immer eine genügende Widerstandsfähigkeit gegen die Fliehkraft.Also according to Fig. 2 and 3, the weld 3 ensures along the entire groove edge Even after smoothing the surface of the seam, there is still sufficient resistance against centrifugal force.
Übrigens können auch die an den Stirnflächen des Läufers liegenden Teile der Kühlkanäle gemäß der Erfindung ausgebildet werden.Incidentally, the parts of the cooling channels located on the end faces of the rotor can also be used be formed according to the invention.
Durch die Ausbildung der genuteten Kühlkanäle gemäß der Erfindung wird der Anschluß derselben an die Zu- bzw. Ableitungskanäle überhaupt nicht beeinflußt. Diese Anschlüsse erfolgen also in der im Hauptpatent geschilderten Weise.By forming the grooved cooling channels according to the invention, the connection the same to the inlet and outlet channels is not influenced at all. These connections therefore take place in the manner described in the main patent.
