Description
Die als Feldmagnete dienenden Läuferkörper zweipoliger Turbogeneratoren wurden mit den Wellenstummeln mittels Stirnscheiben verbunden, die zweckmäßig mit den Wellenstummein aus einem Stück bestehen und mit Rücksicht auf die hohen Beanspruchungen aus einem einzigen Stück Stahl geschmiedet werden sollen. Die Stirnscheiben mußten dabei zum Zwecke der Lüftung mit Durchbrechungen und Kanälen ausgerüstet sein. Die Herstellung derartiger Stücke bietet Schwierigkeiten ; auch ist es schwer, bei hoch beanspruchten Maschinen für den nötigen Durchtrittsquerschnitt der Kühlluft zu sorgen.The rotor bodies of two-pole turbo-generators, which serve as field magnets, were connected to the stub shafts by means of end disks, which are expediently connected to the stub shafts consist of one piece and are forged from a single piece of steel, taking into account the high stresses and strains should. The front disks had to have openings for ventilation and channels. The manufacture of such pieces presents difficulties ; It is also difficult to find the necessary passage cross-section in highly stressed machines to ensure the cooling air.
Die Erfindung betrifft nun eine Verbindung der Wellenstummeln mit dem Magnetkörper desLäufers, die die obigen Nachteile beseitigt.The invention now relates to a connection between the stub shafts and the magnet body of the runner, which overcomes the above disadvantages.
Gemäß der Erfindung kommt es darauf an, daß die Wellenstummeln mittels frei endender strahlenförmiger Arme mit dem Läuferkörper verbunden sind.According to the invention, it is important that the stub shafts by means of free ends radial arms are connected to the rotor body.
Abb. ι und 2 der Zeichnung zeigen ein Ausführungsbeispiel der neuen Verbindung im Längsschnitt bzw. in Stirnansicht.Fig. Ι and 2 of the drawing show an embodiment of the new connection in longitudinal section or in front view.
ff ist der zylindrische Läuferkörper in dessen Nuten b die Feldwicklung untergebracht ist. c sind die Wellenstummeln, die an ihren Enden strahlenförmige Arme d tragen, die sich bis zum Umfang des Läuferkörpers α erstrecken und frei enden. Die Wellenstummeln sind mittels dieser strahlenförmigen Arme d durch Schrauben e mit dem Läuferkörper α verbunden. ff is the cylindrical rotor body in whose slots b the field winding is housed. c are the stub shafts that have radial arms d at their ends, which extend to the circumference of the rotor body α and end freely. The stub shafts are connected to the rotor body α by means of these radial arms d by screws e.
Die Arme wirken als Ventilatorschaufeln, so daß bei Anordnung einer geeigneten Verkleidung oder von Luftlenkringen/ (Abb. 1) am Ständer die Luft in der Pfeilrichtung angesaugt und in den Luftspalt der Maschine gefördert wird.The arms act as fan blades so that when a suitable shroud is in place or by air guide rings / (Fig. 1) on the stand, the air is sucked in in the direction of the arrow and is conveyed into the air gap of the machine.
Die mit Strahlenarmen ausgerüsteten WeI-lenstummeln lassen sich verhältnismäßig leicht erzeugen, und die zwischen den Strahlenarmen frei bleibenden Ausschnitte ergeben einen reichlichen Querschnitt für die Luftförderung. Selbstverständlich müssen die Strahlenarme d nicht geradlinig ausgeführt werden, sondern könnten auch eine schaufelartige Krümmung erhalten.The shaft stubs equipped with radiation arms can be produced relatively easily, and the cutouts that remain free between the radiation arms provide a generous cross-section for conveying air. It goes without saying that the beam arms d do not have to be designed in a straight line, but could also have a shovel-like curvature.
