Description

Bekannt sind bereits z. B. doppel-T-förmige Blechstreifen bzw. Flachkeile zum Zusammenspannen von Blechpaketen für elektrische -Maschinen, die in an der Oberfläche des Blechpaketes angebrachte Nuten eingelegt werden. Diese bekannten Blechstreifen haben den -Nachteil, daß bei ihrer Herstellung aus einer Blechbahn verhältnismäßig viel Abfälle entstehen, die ungenutzt weggeworfen «-erden müssen.Are already known z. B. double-T-shaped sheet metal strips or flat wedges for clamping together sheet metal stacks for electrical machines that are in on the surface Grooves made in the laminated core are inserted. These known sheet metal strips have the disadvantage that in their production from a sheet metal sheet relatively a lot of waste is created that has to be thrown away unused.

Die bekannten Flachkeile sind in Fig. i und 2 der Zeichnung dargestellt.The known flat wedges are shown in FIGS. 1 and 2 of the drawing.

Fig. 2 zeigt, daß neben den Blechstreifen bzw. Flachkeilen i Abfallstü clie 2 übrigbleiben. Gemäß der Erfindung werden nun die erwähnten -Nachteile dadurch vermieden, daß man den Blechstreifen an seinen Enden mit Ösen versieht, mittels welcher er auf an den Stirnblechen des Blechpaketes befindliche -Nasen aufgezogen wird.Fig. 2 shows that in addition to the sheet metal strips or flat wedges i waste pieces clie 2 remain. According to the invention, the mentioned disadvantages are now thereby avoided that one provides the metal strip at its ends with eyelets, by means of which it is pulled onto the lugs located on the end plates of the laminated core will.

In den Fig.3bis 3 sind Ausführungsbeispiele für den Erfindungsgegenstand dargestellt. Fig. 6 zeigt im Vergleich zu Fig. 5 ein Endblech, wie es in Verbindung mit den bekannten Blechstreifen verwendet wurde.In Figures 3 to 3 are exemplary embodiments for the subject of the invention shown. In comparison to FIG. 5, FIG. 6 shows an end plate as it is in connection was used with the known sheet metal strips.

Die Blechstreifen 3 werden, -,vie man aus Fig. 4. ersieht, abfallos aus einer Blechbahn herausgestanzt und erhalten quer zu ihrer Achse verlaufende Schlitze 4., mit denen sie auf Nasen 5 der Stirnbleche 6 befestigt werden. Die Blechstreifen fallen so überall gleich breit aus. .The sheet metal strips 3 are, as can be seen from FIG. 4, without waste punched out of a sheet metal sheet and obtained transverse to its axis Slots 4, with which they are attached to lugs 5 of the face plates 6. The sheet metal strips are the same width everywhere. .

Zum Spannen von Blechpaketen erheblicher Länge können außer an den Enden der Blechstreifen auch noch in ihrem mittleren Teil eine oder mehrere Ausnehmungen vorgesehen sein, die auf -Nasen gesetzt «-erden, «-elche sich an im Innern des Blechpaketes liegenden Blechen befinden.For clamping sheet metal stacks of considerable length, in addition to the Ends of the sheet metal strips also have one or more recesses in their middle part be provided, which are placed on -noses "-earth," which are located inside the laminated core lying sheets.
