  Druckfinger für die Zähne von Blechpaketen elektrischer Maschinen. 



   Fig. i ist die Ansicht eines Teiles einer Druckvorrichtung für die Blechpaket einer elektischen Maschine. Fig. 2 zeigt den Schnitt durch diese Platte nach   A-B.   Auf die Zähne c der Bleche wird der Druck des Presskörpers b durch Druckfinger a übertragen. Diese Druckfinger

 zu halten, um so durch Verringerung der Wärmeableitung mit einer kleineren Schweissmaschine auszukommen. 



   Durch Vertiefungen wie g und   li   wird die Festigkeit der Druckfinger nur ganz unwesentlich beeinträchtigt und dennoch eine sichere Auflage und Druckübermittlung auf die   Endbleche f   erzielt. 



   Zum Anschweissen von Druckfingern ohne Aushöhlungen musste man mit grossen Schweissmaschinen arbeiten und infolge der grösseren Energiemenge die   Endbleche f der   Gefahr der Überhitzung aussetzen. Wollte man aber ohne Schweissung auskommen, musste man entweder die Druckfinger a mit dem   Presskörper   b aus einem Stück herstellen, was infolge des erforderlichen hochwertigen Materiales sehr teuer war, oder man musste die   Endbleche. f mit   den Druckfingern

 wandfreien Verbindungen lieferte, weil das im Vergleich zu den Druckfingern dünne Endblech f sich an den Verbindung stellen leicht ausbeulte.

  Pressure fingers for the teeth of sheet metal stacks of electrical machines.



   Fig. I is a view of part of a printing device for the laminated core of an electrical machine. Fig. 2 shows the section through this plate according to A-B. The pressure of the pressed body b is transmitted to the teeth c of the metal sheets by pressure fingers a. These pressure fingers

 in order to get by with a smaller welding machine by reducing the heat dissipation.



   The strength of the pressure fingers is only negligibly affected by depressions such as g and li, and a secure support and pressure transfer to the end plates f is nevertheless achieved.



   To weld pressure fingers without cavities, one had to work with large welding machines and, as a result of the greater amount of energy, expose the end plates to the risk of overheating. But if you wanted to do without welding, you either had to manufacture the pressure fingers a with the press body b from one piece, which was very expensive due to the high quality material required, or you had to use the end plates. f with the pressure fingers

 flawless connections because the end plate, which is thin compared to the pressure fingers, bulged slightly at the connections.
