Description
Igehrpoliger Läuferkörper mit ausgeprägten Polen für elektrische Maschinen, bei dem die Polschenkel mit der Welle aus einem Stück bestehen Mehrpolige Läuferkörper mit ausgeprägten Polen für elektrische Maschinen werden mit Rücksicht auf die bei Turbogeneratoren geforderten hohen Umlaufzahlen urid die hierdurch hervorgerufene hohe Fliehkraftbeanspruchung mit der Welle aus einem Stück aus Stahl geschmiedet. Diese Herstellungsart bietet aber bei Maschinen für höhere Leistungen und dementsprechend größeren Abmessungen große Schwierigkeiten. Erfindungsgemäß werden diese Schwierigkeiten dadurch vermindert, daß der Läuferkörper in der zur Welle senkrechten Mittelebene der Polschenkel unterteilt ist.1-pole rotor body with pronounced poles for electrical machines, in which the pole legs and the shaft are made in one piece. Multipole rotor bodies with pronounced poles for electrical machines are given in consideration of the at Turbo generators required high numbers of revolutions and the resulting one high centrifugal force with the shaft forged from one piece of steel. However, this type of production offers machines for higher performance and accordingly larger dimensions cause great difficulties. According to the present invention, these difficulties become apparent reduced by the fact that the rotor body is in the central plane perpendicular to the shaft the pole leg is divided.
In der Zeichnung sind zwei Ausführungsbeispiele des Läuferkörpers in Seitenansicht, teilweise geschnitten, dargestellt.In the drawing are two embodiments of the rotor body shown in side view, partly in section.
Abb. i ist ein vierschenkeliger Läuferkörper und Abb. 2 ein Läuferkörper, bei dem je vier Magnetschenkel in zwei Ebenen angeordnet sind.Fig. I is a four-legged rotor body and Fig. 2 is a rotor body, in which four magnet legs are arranged in two planes.
Abb. 3 ist ein auf die Welle senkrechter Schnitt eines Polschenkels gemäß Abb. ?-i ist die Welle und 2 die nabenartige Verstärkung derselben, mit der die Magnetschenke13 zusammenhängen. Der ganze Körper ist in der zur Welle i senkrechten Ebene x-x in zwei Hälften A und B unterteilt.Fig. 3 is a perpendicular to the shaft section of a pole leg according to Fig.? -I is the shaft and 2 is the hub-like reinforcement of the same, with which the magnet legs13 are connected. The whole body is divided into two halves A and B in the plane xx, which is perpendicular to shaft i.
Bei Läuferkörpern, bei denen die Polschenkel in mehreren, etwa wie in Abb. 2 in zwei Ebenen angeordnet sind, erfolgt die Unterteilung in der zur Welle i senkrechten Mittelebene x-x bzw. x'-x' eines jeden Polschenkelkranzes, d. h. in drei Teilen A, C, B. Durch diese Unterteilung wird der feste Zusammenhang zwischen den Schenkeln und der Welle nicht gestört, dagegen ergeben sich verhältnismäßig einfach herstellbare Stücke, die miteinander in einfachster Weise fest verbunden werden können, infolge der eigenartigen Unterteilung die Verbindungsstellen durch die Fliehkraft nicht beansprucht werden.In rotor bodies in which the pole legs are arranged in several planes, for example in two planes as in Fig. 2, the subdivision takes place in the central plane xx or x'-x 'of each pole leg ring, which is perpendicular to the shaft i, i.e. in three parts A, C, B. This subdivision does not disturb the fixed connection between the legs and the shaft, on the other hand there are pieces that are relatively easy to manufacture and can be firmly connected to one another in the simplest possible way .
Gemäß Abb, i erfolgt die Verbindung der Läuferteile mittels in Ringnuten der Stirnflächen der Polschenkel versenkter Ringe q., während gemäß Abb. z und 3 auf die zweiteiligen Schenkel Stahlhülsen g aufgeschoben sind, welche in an und für sich bekannter Weise die Feldspulen tragenkönnen. Selbstverständlichkönnen die in Abb. i und 2 dargestellten beiden Verbindungsarten auch gleichzeitig angewendet werden.According to Fig. I, the rotor parts are connected by means of annular grooves of the end faces of the pole legs of countersunk rings q., while according to Fig. z and 3 on the two-part legs steel sleeves g are pushed, which in and can carry the field coils in a manner known per se. Of course, the Both types of connection shown in Fig. i and 2 are also used simultaneously will.
