Description

  

  Blechpaket mit Abstandshaltern für elektrische Maschinen.    Bekanntlich wird bei elektrischen Ma  schinen der aktive Blechkörper so in Pakete  unterteilt, dass zwischen denselben Luftschlitze  entstehen, durch welche Kühlluft getrieben  wird. In diese Luftschlitze werden Abstands  halter eingelegt, welche Bekannterweise durch  Nieten, Löten oder Schweissen mit den Blech  segmenten verbunden werden, um gegen     Vi-          Brationen    und Herausfallen gesichert zu sein.  



  Diese Operationen sind immer zeitraubend  und gewähren zudem keine absolute Sicher  heit gegen Lockerwerden und Herausfallen  der Abstandshalter.    Die     Erfindung    hat ein Blechpaket mit  Abstandshaltern zum Gegenstand, die haken  förmige Ansätze aufweisen, die achsial durch  Schlitze der ersten Segmentlagen einführbar  und radial in Schlitze der nächstfolgenden  Segmentlagen verschiebbar sind, derart, dass  sie im gepressten Blechkörper festsitzen.  



  Die beiliegende Zeichnung zeigt im     Quer-          schnitt    und in Stirnansicht ein Ausführungs  beispiel des Erfindungsgegenstandes.    Die Verbindung der im Querschnitt     U-          förmigen    Abstandshalter 1 mit dem     lamel-          lierten    Blechkörper 3 wird dadurch herge  stellt, dass die Haken 2 der Abstandshalter  durch Schlitze 4 des lamellierten Blechkörpers  achsial eingeführt und durch radiale Ver  schiebung endgültig in Schlitze 5 der nächst  folgenden Blechsegmente zu liegen kommen.  Nach der Pressung der Blechkörper findet  dann eine gesicherte Verschachtelung von Ab  standshalter und Blechsegment statt, ohne  dass dadurch die Blechsegmente unter sich  leitend verbunden werden.



  Laminated core with spacers for electrical machines. As is known, in electrical machines, the active sheet metal body is divided into packets so that air slots are created between the same through which cooling air is driven. In these air slots spacers are inserted, which are known to be connected to the sheet metal segments by riveting, soldering or welding in order to be secured against vibrations and falling out.



  These operations are always time consuming and do not guarantee absolute security against loosening and falling out of the spacers. The invention relates to a laminated core with spacers which have hook-shaped lugs that can be axially inserted through slots in the first segment layers and radially displaced into slots in the next segment layers so that they are stuck in the pressed sheet metal body.



  The accompanying drawing shows an embodiment of the subject of the invention in cross section and in front view. The connection of the cross-sectionally U-shaped spacer 1 with the laminated sheet metal body 3 is produced by inserting the hooks 2 of the spacers axially through slots 4 of the laminated sheet metal body and finally shifting them radially into slots 5 of the next following sheet metal segments come lying down. After the sheet metal body has been pressed, the spacer and sheet metal segment are securely nested without the sheet metal segments being conductively connected to one another as a result.
