Description

itänderblechpaket für elektrische Maschinen Es wurde schon vorgeschlagen, bei elektrischen Maschinen das `.itänderblechpaket.unmittelbar mit einem GrauguUgehäuse zu umgießen. Nach dem Erkalten des Graugusses treten Schrumpfspannun,:,eri auf, die zu Rissen im Gehäuse unu auch zu Beschädigungen des Blechpaketes führen können. Um dies zu vermeiden, wurde bereits eine Reihe von Vorschlägen gemacht, die mehr oaer weniger Aufwahd erfordern. Der Erfindung liegt die Aufgabe zu Grunae-, die beim Umgießen eines #Ständerblechpaketes mit Grauguß auftretenuen Schrumpf-Spannungen auf das notwendige Mindestmaß mit sehr einfachen Mitteln herabzusetzen.- Sie erreicht dies dadurch, daß das Stännerblechpaket vor dem Umgießen mit nahe seinem Außen- umfang uns in Umfangsrichtung verlaufenden schlitzartigen Aussparungen versehen ist, deren Abmessungen, insbesondere höhe, aer Schrumpfdifferenz zwischen dem Gehäuse und dem Blechpaket angepaßt sina. Beim Erkalten des Graugusses werden die erfindungsgemäßen Aussparungen zusammengepreßt, wodurch eine Verminderune des Blechpaketumfanges eintritt. Damit werden Besct@digungen des Paktes uns cies Gehäuses vermieden. Die Zeichnung zeigt in Fig..l einen Teil eines.Stdnderblecrpaketes vor- dem Umgießen mit Grauguß und in Fig. 2 nach aem Umgießen mit dem Graugut?. Wie aus Fig. 1 ersichtlich, ist das Blechpaket 1 in der Nähe seines Außenumfanges ? mit in Umfangsrichtung verlaufendem schlitzartigen Ausnehmuneen 3 versehen. Wird das Paket mit dem Grasgußgehäuae 4 umgossen, dann erfolat.beim-.Erstarrep des Graugusses ein Druck sui den Paketumfang, woaureh die Aussparungen 3 zusammengedrückt werden. Daaurch wiederum verminsert sich der Außenumfang des haketes, und zwar um die Differenz zwischen dem Kreisbogen I des ursprünglichen Umfanges und der durch das Zusammendrücken der Schlitze entstehenden Umfangssehne 6. Bemißt man die Aussparungen 3 insbesondere in ihrer Höhe entsprechend, dann verbleibt von der Schrumpfspannung des erstarrenden Graugußgehäuses nur so viel, daß das Paket fest. im Gehäuse sitzt, jedoch keine Beschädigungen desselben oder des Paketes erfolgen.itänderblechpaket for electrical machines, it has been suggested that `.itänderblechpaket.unmittelbar to recast in electrical machines with a GrauguUgehäuse. After the gray cast iron has cooled down, shrinkage stresses occur, which can lead to cracks in the housing and damage to the laminated core. To avoid this, a number of proposals have already been made that require more or less effort. The invention aims to Grunae- that herabzusetzen.- the recasting of a # stator core with cast iron shrinkage stresses auftretenuen to the minimum necessary by very simple means to achieve this in that the Stännerblechpaket before casting around with extensive near its outer Us circumferentially extending slot-like recesses is provided, the dimensions, in particular height, of the shrinkage difference between the housing and the laminated core is adapted. When the gray cast iron cools, the recesses according to the invention are pressed together, as a result of which the circumference of the laminated core is reduced. In order to avoid us cies housing Besct @ endings of the Covenant. The drawing shows a part in Fig..l eines.Stdnderblecrpaketes forward the casting around with gray cast iron and in Fig. 2 by insert molding with the AEM Graugut ?. As can be seen from Fig. 1, is the laminated core 1 in the vicinity of its outer circumference ? provided with slot-like recesses 3 running in the circumferential direction . If the package with the Grasgußgehäuae 4 is poured, then when the gray cast iron solidifies, a pressure sui the package circumference, where the recesses 3 are pressed together. Daaurch turn, the outer peripheral verminsert of haketes, namely to the recesses 3 according to the difference between the arc I of the original scope and resulting from the compression of the slots circumferential tendon 6. determined particularly in height, then remains of the shrink tension of the solidifying Cast iron housing only so much that the package is stuck. sits in the housing, but there is no damage to the same or to the package.
