  Einrichtung und Verfahren zur Befestigung und Zentrierung von Ständerblechkörpern elektrischer
Maschinen in ihren Gehäusen. 



   Es ist bekannt, die Ständerbleche elektrischer Maschinen derart in einem   Gehäusemaliel   aus Blech oder Guss zu lagern und befestigen, dass die Bleche nach dem Einschichten in das Gehäuse zusammengepresst und unter Druck durch Verwendung von Sprengringen oder Klammern, ferner durch Verschrauben, Vernieten oder Verschweissen mit dem Gehäuse verbunden werden. 



   Es ist ferner bekannt, den vorgepressten   Ständerblechkörper   mit flüssigem Leichtmetall zu   Ulll-   giessen, so dass nach dem Erstarren der umgossene Gehäusemantel den Ständerblechkörper umschliesst und zusammenhält. Diese wirtschaftliche Methode erfordert zu ihrer Anwendung entsprechend grosse Gussformen und zwingt zur Einhaltung eines bestimmten Masehinendurchmessers, besonders wenn die 
 EMI1.1 
 Kühlluft die Möglichkeit zu geben, über den Rücken des   Ständerblechkörpers   zu streichen, muss das umgossene Gehäuse stellenweise den Ständerrücken freigeben. Dadurch ergibt sich konstruktiv ein entsprechend vergrösserter Durchmesser des Gehäusemantels, in weiterer Folge auch der Lagerschilde und schliesslich eine Erhöhung des Maschinengewichtes. 



   Gegenstand der vorliegenden Erfindung ist eine Befestigungsart des Ständerblechkörpers (S) in dem Gehäusemantel (M) derart, dass in dem Raum zwischen   Ständerblechrücken   und Innenbohrung des Gehäusemantels an einzelnen Stellen unter Verwendung einfacher Einlegeformen Klammern (K) aus Leichtmetall eingegossen werden. Der Gehäusemantel erhält an den Stellen, wo eine Klammer zu sitzen kommt, Ausnehmungen, in welche das   flüssige   Metall hineinfliesst und nach dem Erstarren eine Art Nietverbindung der Klammer mit dem Gehäusemantel herstellt. Nach dem Erstarren des Klammermetalls werden die Einlegeformen entfernt und der Ständerblechkörper erscheint im Gehäuse   festgelaert   und zentriert. 



   Durch   Verwendung eines Gehäusemantels,   z. B. aus Blech, und Anordnung   möglichst   niedriger Klammern kann der Luftspalt für die   Kühlluft   zwischen dem Ständerblechrücken und der Gehäuseinnenbohrung sehr klein gehalten werden. Damit wird der Maschinendurehmesser und Lagerschilddurchmesser sehr klein und in weiterer Folge auch das Gesamtgewicht der Maschine erheblich verringert.

  Device and method for fastening and centering sheet metal stator bodies
Machines in their housings.



   It is known to store and fasten the stator sheets of electrical machines in a housing made of sheet metal or cast iron such that the sheets are pressed together after being layered in the housing and under pressure by using snap rings or clips, and also by screwing, riveting or welding to the Housing are connected.



   It is also known to Ulll cast the pre-pressed laminated stator body with liquid light metal, so that after solidification, the encapsulated housing jacket surrounds the laminated stator body and holds it together. This economical method requires correspondingly large molds to be used and requires compliance with a certain internal diameter, especially if the
 EMI1.1
 To give cooling air the opportunity to brush over the back of the laminated stator, the encapsulated housing must release the back of the stator in places. This results in a correspondingly enlarged diameter of the housing jacket, and subsequently also of the bearing shields, and finally an increase in the weight of the machine.



   The subject of the present invention is a method of fastening the laminated stator body (S) in the housing shell (M) in such a way that brackets (K) made of light metal are cast in the space between the stator sheet metal back and the inner bore of the housing shell at individual points using simple insert forms. The housing jacket is provided with recesses at the points where a clamp is seated, into which the liquid metal flows and, after solidification, creates a kind of riveted connection between the clamp and the housing jacket. After the staple metal has solidified, the insert forms are removed and the sheet metal stator body appears to be fixed and centered in the housing.



   By using a housing jacket, e.g. B. made of sheet metal, and the arrangement of the lowest possible brackets, the air gap for the cooling air between the stator back and the housing inner bore can be kept very small. This means that the machine diameter and the end shield diameter are very small and, as a result, the overall weight of the machine is reduced considerably.
