Description
Gegenstand der Erfindung ist eine Anordnung der Preßvorrichtung für die Ankerblechpakete großer elektrischer Maschinen. Man hat seither die Fingerplatten, die die Anker-The subject of the invention is an arrangement of the pressing device for the laminated core large electrical machines. Since then, the finger plates that hold the anchor
' 5 bleche zusammenpressen, aus unmagnetischem Material hergestellt, um die magnetischen Verluste durch das Streufeld in diesen Teilen klein zu halten. Infolge zunehmender Knappheit des hierfür in Frage kommenden Materials' 5 Press together metal sheets, made of non-magnetic material in order to keep the magnetic losses due to the stray field in these parts small. As a result of the increasing scarcity of the material in question
ίο hat man sich darauf beschränkt, die auf den Zahnpaketen aufliegenden Druckfinger aus unmagnetischem Nickelstahl herzustellen, hat dagegen für die Preßplatten selbst billigeren magnetischen Stahl verwendet.ίο one has limited oneself to the To produce tooth packets resting pressure fingers from non-magnetic nickel steel, has on the other hand, cheaper magnetic steel is used for the press plates themselves.
Um nun den hochwertigen Nickelstahl für die Druckfinger entbehrlich zu machen, werden gemäß der Erfindung die Druckfinger ; quer zum Ankerblechpaket geblättert. Es ' wird hierdurch erreicht, daß die magnetischen Verluste unter allen Umständen klein ausfallen, darüber hinaus aber auch der wesentliehe Vorteil, daß jetzt Konstruktionsmaterialien verwendet werden können, die sich den üblichen Konstruktionsmaterialien des Dynamobaues ohne weiteres anpassen. Die Blechstücke, die die Druckfinger gemäß der Erfindung zusammensetzen, können aus den Abfallstücken der übrigen Bleche hergestellt werden.In order to make the high-quality nickel steel for the pressure fingers dispensable, the pressure fingers are according to the invention; Scrolled across the anchor plate package. It 'is achieved thereby that the magnetic losses turn out at all costs small, but in addition also the wesentliehe advantage that now construction materials can be used that conform to the usual materials of construction Dynamobaues easily. The sheet metal pieces that assemble the pressure fingers according to the invention can be made from the scrap pieces of the remaining sheets.
In der Zeichnung sind einige Ausführungsbeispiele gemäß der Erfindung veranschaulicht. Das Druckfingerblechpaket α wird bei der Anordnung gemäß Fig. 1 und 2 in Nuten der Preßplatte b eingesetzt und an den Endblechen des Ankerblechpaketes befestigt. Die Bleche des Druckfingers sind, in geeigneter Weise durch Niete,- Punktschweißung untereinander verbunden. An den Endblechen läßt man zweckmäßig Zapfen c vorstehen, die in die Endbleche d des Ankerblechpaketes e eingezapft werden.Some exemplary embodiments according to the invention are illustrated in the drawing. In the arrangement according to FIGS. 1 and 2, the pressure finger plate package α is inserted into grooves in the pressure plate b and attached to the end plates of the armature plate package. The metal sheets of the pressure finger are connected to one another in a suitable manner by means of rivets - spot welding. Expediently, pins c are allowed to protrude from the end plates and are pegged into the end plates d of the armature lamination packet e .
Eine andere Befestigungsweise zeigt Fig. 3. Hiernach wird der in die Preßplatte eingreifende Teil des Blechpakets gespreizt und die gespreizten Bleche in die Preßplatte eingegössen. Um ein Umkippen der Bleche beim Vergießen zu vermeiden, werden die gespreizten Bleche/ zweckmäßig auf Drähte g, h aufgereiht. Another method of fastening is shown in FIG. 3. Thereafter, the part of the laminated core that engages in the press plate is spread and the spread sheets are cast into the press plate. In order to prevent the sheets from tipping over during casting, the spread sheets / are expediently lined up on wires g, h.
