Description

in. dem- Patent 859 498 ist eine durchzugsbelüftete elektrische Maschine beschrieben, bei der in das hohlzylinderförmigeGehäuse ein polygonales, vorzugsweise viereckiges Ständerblechpaket eingebaut ist. Es hat in den. magnetischem nicht oder weniger wirksamen Ecken axial verlaufende, durch Aussparungen gebildete Kühlkanäle; durch die ein Kühlluftstrom hindurchgeblasen wird. Die das Blechpaket zusammenhaltenden Druckfinger oder Endbleche erstrecken sich abweichend von dem P,ckigen Profil des Blechpakets ringsherum bis an die GehäusennenlIche.in. patent 859 498 is a ventilated electrical machine described, in which a polygonal, preferably square stator core is installed. It has in the. magnetic not or less effective corners axially running cooling channels formed by recesses; through which a flow of cooling air is blown. The ones holding the laminated core together Pressure fingers or end plates extend differently from the square profile of the Laminated core all around up to the housing face.

Die Erfindung betrifft eine weitere; besonders zweckmäßige Ausgestaltung einer derartigen Maschine. (Erfindungsgemäß ist das Blechpaket an den Ecken durch mit den Druckringen, fest verbundene Rohre zusammengehalten, die gleichzeitig die Kühlkanäle bilden. Dadurch werden die sonst für die Aussparungen der Kühlkanäle erforderliehen Raumteile gleichzeitig für die mechanische Verbindung des Blechpakets ausgenutzt. Die Rohrverbindung bietet ferner noch den besonderen Vorteil, daß das Blechpaket zusammen mit den Druckringen stark versteift wird. Im selben Maße kann das Gehäuse schwächer ausgebildet werden. Im übrigen ergeben sich die gleichen Vorteile wie beim Patent 859 498. Die Wicklung kann bequem außerhalb des Gehäuses im Blechpaket hergestellt werden. Sie ist auch beim Transport gegen Beschädigungen geschützt. Das Ständerblechpaket läßt sich leicht transportieren, @da es sich .auf den runden' Druckringen rollen läßt, außerdem fallen besondere Leitbleche für die Kühlluftführung fort.The invention relates to another; particularly useful design such a machine. (According to the invention, the laminated core is through at the corners with the pressure rings, firmly connected pipes held together, which at the same time the Form cooling channels. This is what would otherwise be required for the recesses in the cooling ducts Required space parts at the same time for the mechanical connection of the laminated core exploited. The pipe connection also offers the particular advantage that the Laminated core is stiffened together with the pressure rings. To the same extent can the housing can be made weaker. Otherwise, the same advantages result as in patent 859 498. The winding can conveniently be placed outside the housing in the laminated core getting produced. It is also protected against damage during transport. The stator core is easy to transport, @ because it is 'on the round' Pressure rings can roll, and there are also special baffles for guiding the cooling air away.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt (Fig. z und 2). Das zwischen den kreisförmigen Druckringen i angeordnete viereckige Blechpaket 2 wird durch in den Ecken sitzende, mit den Druckringen i verwalzte Rohre 3 fest zusammengehalten. Die Rohre haben einen so großen lichten Durchmesser; daß ihr Innenraum gleichzeitig für den Durchtritt der Kühlluft ausgenutzt werden kann. Das Blechpaket ist in ein zylindrisches Gehäuse 5 eingesetzt. .An embodiment of the invention is shown in the drawing (Figs. Z and 2). The square one arranged between the circular pressure rings i Laminated core 2 is driven by tubes that are seated in the corners and rolled with the pressure rings i 3 held together tightly. The tubes have such a large inside diameter; that their interior space can be used at the same time for the passage of the cooling air. The laminated core is inserted into a cylindrical housing 5. .
