Description
Einrichtung zum magnetischen Verschluß offener Nuten in elektrischen Maschinen. Bei der im Hauptpatent beschriebenen Einrichtung zum magnetischen Verschluß offener Nuten ist ein vollständiger Abschluß der Nuten nur möglich, wenn man die Verschlußstücke so stark unterteilt, daß sich jedes nur über einen Zahn und zwei Nuten erstreckt, und wenn man den Eisenkörper der Maschine aus gegeneinander versetzten Blechen aufbaut (Abb. 6 des Hauptpatents). Will man diese verhältnismäßig umständlichen Mittel vermeiden und trotzdem einen möglichst großen Teil der Nutenöffnungen magnetisch abschließen, so kann man dies erreichen, indem man erfindungsgemäß die Verschlußstücke in achsialer Richtung mehrfach breiter macht als die stehengebliebenen Zahnteile. Eine untere Grenze für die Breite der stehenbleibenden Zahnteile ist nur durch die mechanische Festigkeit gegeben.Device for the magnetic closure of open grooves in electrical Machinery. In the device for magnetic closure described in the main patent open grooves, a complete closure of the grooves is only possible if the Closing pieces so strongly divided that each has only one tooth and two Grooves extends, and if you offset the iron body of the machine from one another Sheet metal builds up (Fig. 6 of the main patent). If you want this relatively cumbersome Avoid means and still magnetically as large a part of the slot openings as possible complete, this can be achieved by the invention the closure pieces in axial direction several times wider than the remaining tooth parts. One lower limit for the width of the remaining tooth parts is only due to the mechanical Given strength.
Ein weiterer Nachteil der im Hauptpatent beschriebenen Einrichtung ist der, daß die Bleche, aus denen die stehengebliebenen Zahnteile bestehen, sich leicht etwas aufblättern, wodurch das Einsetzen der Verschlußstücke bedeutend erschwert wird. Dieser Nachteil kann erfindungsgemäß dadurch vermieden werden, daß die stehenbleibenden Zahnteile aus einem einzigen Blech hergestellt werden, welches natürlich stärker gewählt werden kann als die Bleche, aus denen der Eisenkörper der Maschine im übrigen aufgebaut ist. Eine obere Grenze für die Blechstärke ist nur durch die Wirbelstrombildung gegeben. Zwischen den beiden genannten Grenzen für die Blechstärke liegt ein genügender Spielraum für den Konstrukteur. Durch feinere Unterteilung in achsialer Richtung, d. h, größere Anzahl der Verschlußstücke, kann dieser Spielraum noch vergrößert werden.Another disadvantage of the device described in the main patent is that the metal sheets, from which the remaining tooth parts consist, are easy to peel open, which makes it much more difficult to insert the locking pieces will. This disadvantage can be avoided according to the invention in that the remaining Tooth parts are made from a single sheet of metal, which of course is stronger can be chosen as the metal sheets that make up the rest of the iron body of the machine is constructed. An upper limit for the sheet thickness is only due to the formation of eddy currents given. Between the two mentioned limits for the sheet thickness there is a sufficient one Scope for the designer. Due to a finer subdivision in the axial direction, d. h, a larger number of locking pieces, this margin can be increased will.
Die Abbildungen zeigen ein Ausführungsbeispiel der Erfindung, und zwar Abb. i einen Querschnitt durch einige Nuten, Abb. 2 einen Längsschnitt längs einer Nut und Abb. 3 einen Schnitt längs der Linie A-A (Abb. i).The figures show an embodiment of the invention, and although Fig. i is a cross section through some grooves, Fig. 2 is a longitudinal section a groove and Fig. 3 a section along the line A-A (Fig. i).
a sind die Nuten, b die aus einem einzigen Blech bestehenden stehenbleibenden Zahnteile, c die magnetischen Verschlußstücke, d ist ein Luftschlitz, e ein Nutenkeil. a are the grooves, b the remaining tooth parts consisting of a single sheet of metal, c the magnetic locking pieces, d is an air slot, e a wedge of the groove.
