Description

Nutenisolation fär elektrische Maschinen. Die Isolation der in der Nut liegenden Leiterelektrischer Maschinen besteht vielfach aus einem Isoliermaterial, z. B. Preßspan, das zur Erhöhung der mechanischen Festigkeit mit imprägniertem Leinen, z. B. Exzelsiorleinen, überzogen ist. Die Erfindung betrifft eine Ausführung der Isolation, bei der der teuere Leinenstoff in seiner Wirkung durch besondere Formgebung des Isolationsmaterials ersetzt wird.Slot insulation for electrical machines. The isolation of the Grooved conductor electrical machines often consist of an insulating material, z. B. Pressboard, which to increase the mechanical strength with impregnated linen, z. B. excelsior leashes, is covered. The invention relates to an embodiment of the Isolation, in which the expensive linen material has a special shape in its effect the insulation material is replaced.

Nach der Erfindung werden die Stirnenden des Isolierstoffs zurückgeschlagen, um die äußere Kante mechanisch widerstanids,fähiger zu machen. Fig. i zeigt ein Ausführungsbeispiel. Es bedeutet i i eine Hülse aus Preßspan, die in die Nut einer elektrischen Maschine eingelegt werden soll. Erfindungsgemäß sind die Stirnenden 12 der Hülse zurückgeschilagen. Es wird dadurchl die äußere Kante 13 mechanisch widerstandsfähiger, vor allem wird die Möglichkeit des Einreißens dieser Kante verhindert. Fig. a stellt einen Schnitt durch einen Schenkel der Hülse dar.According to the invention, the front ends of the insulating material are turned back in order to make the outer edge mechanically more resistant. Fig. I shows an embodiment. It means ii a sleeve made of pressboard which is to be inserted into the groove of an electrical machine. According to the invention, the front ends 12 of the sleeve are cut back. As a result, the outer edge 13 becomes more mechanically resistant, and above all the possibility of this edge tearing is prevented. Fig. A shows a section through one leg of the sleeve.

Bei Nutenisolationen, die in an sich bekannter Weise aus mehreren Schichten gleich-oder verschiedenartiger Isolierstoffe bestehen, genügt es nach der Erfindung, `nenn nur einzelne dieser Schichten an den Stirnseiten zurückgeschlagen sind.In the case of slot insulation, which is made up of several in a known manner If there are layers of identical or different insulating materials, it suffices of the invention, `` just name some of these layers turned back on the front sides are.

Fig. 3 zeigt einen Schnitt durch eine in dieser Weise ausgeführte Hülse. Es bedeutet 1q. eine Preßspanhülse, die auf der einen Seite mit einer Schicht von Japan- oder Manilapapier 15 belegt isst. Wie .die Zeichnung erkennen läßt, ist bei dieser Ausführung lediglieh dass Stirnende 16 des Japanpapiers zurückgeschlagen, um bei 17 eine gegen Einreißen verstärkte Kante zu erhalten.Fig. 3 shows a section through one executed in this way Sleeve. It means 1q. a pressboard sleeve, which is on one side with a layer Eats covered by Japanese or Manila paper 15. As the drawing shows, is in this version only the front end 16 of the Japanese paper is turned back, to get an edge reinforced against tearing at 17.

Die äußere Kante 13 bzw. 17 ,der Isolation wird bei !der Herstellung der Wicklung und auch beim Betriebe der Maschine erfahrungsgemäß am stärksten beansprucht, und zwar ist in erster Linie ein Einreißen dieser Kante zu befürchten. Die Verstärkung .dieser Kante in der oben angegebenen Weise verhindert diese Gefahr. Dabei ist es besonders. günstig, die Stirnenden des Isolationsmaterials nach außen zurückzuschlagen, um das Innere der Hülse für die Wicklung freizuhalten.The outer edge 13 or 17 of the insulation is made during manufacture Experience has shown that the winding and the operation of the machine are subjected to the greatest stress, namely, a tearing of this edge is to be feared in the first place. The reinforcement .This edge in the manner indicated above prevents this danger. It is there particularly. favorable to fold back the front ends of the insulation material to the outside, to keep the inside of the sleeve free for winding.
