Description
Geblätterte Magnetkörper für elektrische Maschinen und Apparate, die mit Nuten für die Unterbringung der Wicklung versehen sind, werden bekanntlich im allgemeinen so hergestellt, daß die Bleche einzeln gestanzt und dann geschichtet werden.Laminated magnetic bodies for electrical machines and apparatus with grooves for the accommodation of the winding are provided, as is known, in general so made that the sheets are individually stamped and then layered.
In der Abb. 1 der Zeichnung ist ein Segment für die Blechfeette leiner elektrischen Maschine, in der Abb. 2 'ein Blech für den Aufbau eines Feldpoles und in der Abb. 3 iein Blech für den Aufbau eines E-förmigien Joches für einen Magneten dargestellt. Diese Bleche werden aus ganzen Blechtaieln gestanzt. Die schraffierten Teile müssen dabei herausgestanzt werden, um die Wicklungsnuten zu erzeugen. Diese Art der Herstellung bedingt .einen starken Blechabfall und ist daher -unwirtschaftlich.In Fig. 1 of the drawing is a segment for the Blechfeette leiner electrical Machine, in Fig. 2 'a sheet for the Construction of a field pole and in Fig. 3 a sheet metal for the construction of an E-shape Yoke shown for a magnet. These sheets are punched from whole sheet metal strings. The hatched parts must be punched out to make the winding slots to create. This type of production requires a lot of sheet metal waste and is therefore -uneconomical.
Es ist ferner bereits bekannt, Zähne als Einzelteile am Eisenkörper elektrischer Maschinen anzubringen, zum Zwecke, dadurch das Einarbeiten der Nuten zu vermeiden. Durch den mechanischen und magnetischen Zusammenschluß dieser Teile mit Hilfe von Unterschneidungen, Bandagen, Keilen, Schrauben u. dgl. wurde jedoch die !Fabrikation wesentlich erschwert und verteuert, so daß dem durch Verringerung des. Verschnittes erreichten Vorteil erhebliche Nachteile gegenüberstanden. It is also already known to use teeth as individual parts on the iron body of electrical machines to be attached, for the purpose of avoiding the machining of the grooves. Through the mechanical and magnetic connection of these parts with the help of undercuts, bandages, wedges, Screws and the like, however, the production was made much more difficult and expensive, see above that the advantage achieved by reducing the waste was offset by considerable disadvantages.
Diese Nachteile werden nun erfindungsgemäß dadurch vermieden, daß die Wicklungsnuten von an den Grundkörper jedes einzelnen Bleches angeschweißten Blechzähnen gebildet werden. Hierbei erweist sich die bereits vordem als brauchbar erkannte Stumpfschweißung von Blechteilen aneinander als am zweckmäßigsten, da auf diese Weise die Schweißstelle praktisch nicht verdickt wird.These disadvantages are now avoided according to the invention in that the winding grooves on the base body each individual sheet metal welded metal teeth are formed. This turns out to be the butt welding of sheet metal parts to one another, which was previously recognized as useful as the most appropriate, as in this way the weld is practically not thickened will.
Schweißungjen solcher Art pflegt man bekanntlich bei stumpfem Aufeinanderlegen der Blechkanten und unter Zuführung von Wasserstoff als Schutzgas vorzunehmen. In dieser Art werden1 auch beim Gegenstand der Erfindung die Zähne mit dem Grundkörper in einer -Vorrichtung stumpf zusammengestoßen und festgespannt und dann mittels eines von 'einer WasserstofffLamme umgebenden Lichtbogens vereinigt.Welding of this type is known to be carried out with the sheet metal edges butted one on top of the other and with the supply of hydrogen as a protective gas. In this type 1 may also be collided blunt the subject invention the teeth to the base body in a united apparatus, and tightened and then by means of one of 'a hydrogen flame surrounding the arc.
Durch die Erfindung ist es auch angängig, die Zähne aus einem magnetisch höherwertigen Werkstoff herzustellen als den Grundkörper, wodurch die Kosten für die Herstellung des letzteren auf 'einen Bruchteil derjenigen des hochlegierten Bleches herabgesetzt werden.The invention also makes it possible to make the teeth from a magnetically higher quality Manufacturing material than the base body, reducing the cost of manufacturing the latter to a fraction that of the high-alloy sheet are reduced.
In den Abb. 1 bis 3 bezeichnet α den Grundkörper, b die Wicklungsnuten und c die durch die Schweißstellen bzw. Nähtet an den Grundkörper α angeschweißten Zähne.In Figs. 1 to 3, α denotes the base body, b the winding grooves and c the teeth welded to the base body α through the welds or seams.
