Description

Die Erfindung betrifft eine elektrische Uaschine, deren Blechpakete durch Paketklammern zusammengehalten werden.The invention relates to an electrical machine, the laminated core are held together by package clips.

Es ist bereits bekannt; Blechpakete nicht durch Schrauben und Bolzen zusammenzuhalten, sondern durch aus Blech bestehende Paketklammern. Das Klammern der Blechpakete hat .gegenüber dem Zusammenschrauben und Zusammennieten den Vorteil, daß es wesentlich billiger und einfacher ist. Trotzdem haften aber auch dem Klammern von Blechpaketen mancherlei Mängel an. Die Klammern müssen einzeln angebracht und an den Blechpaketen befestigt werden. Diese Arbeit nimmt verhältnismäßig viel Platz in Anspruch, namentlich dann, wenn die Blechpaketklammern in Form gewölbter Streifen verwendet werden, die man in den Blechpaketrücken erst hineinklopfen muß.It is already known; Sheet metal stacks not through screws and bolts to hold together, but by package clips made of sheet metal. That clinging the laminated core has the advantage over screwing and riveting together that it is much cheaper and easier. Nevertheless, the staples also adhere of laminated cores shows various defects. The brackets must be attached individually and be attached to the sheet metal stacks. This work takes up a relatively large amount of space to claim, especially when the laminated core clips are in the form of curved strips be used, which you must first tap into the back of the sheet metal package.

Gemäß der vorliegenden Erfindung wird nun das Klammern von Blechpaketen wesentlich vereinfacht, wenn man die Paketklammern einfach an ihren Enden umbiegt und in rechteckige Nuten der Blechpakete legt und sie hier durch Anstauchüngen hält. Die Anstauchungen können cri den Blechpaketnücken angebracht werden. Es empfiehlt sich, je eine Anstauchung in der Nähe eines Stirn-Bleches vorzusehen und die übrigen-Anstauchungen an dem zwischen diesen Anstauchungen befindlichen Teil anzubringen. Die Anstauehungen liegen in Nähe der Stirnbleche vorteilhaft paarweise einander gegenüber. In den zwischen diesen Anstauchungen liegenden mittleren Teilen können die Anstauchungen gegeneinander versetzt- sein, -In der Zeichnung ist ein Ausführungsbeispiel dargestellt.According to the present invention, the stapling of laminated cores is now much easier if you simply bend the package clips at their ends and lays them in rectangular grooves in the laminated cores and holds them here by upsetting them. The upsets can be attached to the back of the sheet metal core. It recommends to provide one upset in the vicinity of a face plate and the other upset points to be attached to the part located between these upsets. The damming are advantageous in pairs opposite one another in the vicinity of the end plates. In the The central parts lying between these upsets can cause the upsets be offset from one another, -In the drawing, an embodiment is shown.

Fig. -i veranschaulicht schematisch die Herstellung der einzelnen Streifen, die in Fig. 2 im Schnitt und in Fig. 3 in Seitenansicht dargestellt sind; Fig. q. zeigt einen Querschnitt durch eine im Blechpaketrücken befindliche Nut, in welche der Blechstreifen, der. _zümKlammern des. Paketes dient, eingelegt wird; Fig: 5 zeigt eine Draufsicht auf einen Paketrücken mit zwei Klammern; von denen eine von der Seite zu sehen ist. -Die Herstellung der neuen Paketklammern ist im Gegensatz zu der Herstellung der bisherigen Klammern außerordentlich einfach. Die Blechtafel T wird der Stanze 2 zugeführt. Mit jedem Hub des Stanzwerkzeugs 2 werden zwei Streifen 3 und s abgestanzt. Der Anschlag 5 ist so eingestellt, daß der Streifen 3 die gleiche Breite erhält wie der Streifen .4. Die Blechtafel i wird mittels des Schiebers 6, an welchem über das Zugseil 7 das Gewicht 8 angreift, in Richtung des Pfeiles. 9 geschoben, bis er sich an den Anschlag 5 anlegt, so daß wieder zwei Streifen abgestanzt werden können. Die Streifen haben, wie Fig. 2 zeigt, einen einfachen rechteckigen Querschnitt. Sie werden an ihren Enden hochgebogen, wie Fig. 3 veranschaulicht, und entweder glatt oder vorgebogen in die Nuten To des Blechpaketrückens eingelegt. Wie Fig. 5 zeigt, wird der Streifen i!i mittels der Anstauchungen,i.2 und 13 festgehalten, so daß er aus der Nut To nicht herauszutreten vermag. Die Klammer 14 ist an ihren Enden, wie bei 15 angedeutet, scharf eingebogen. Die Anstauchungen z2° und 13 haben einerseits die Aufgabe, ein Herausfallen der Blechstreifen aus den Nuten zu verhindern, andererseits aber auch die Klammern in axialer Richtung derart zu entlasten, daß von den -umgebogenen Klammerenden im wesentlichen nur die Masse der an den Enden liegenden Bleche einwirkt, während der Preßdruck der in der Mitte liegenden Bleche im wesentlichen durch die Anstäüchüngen von den mittleren Teilen der Blechstreifen aufgenommen werden.FIG. 1 schematically illustrates the production of the individual strips, which are shown in section in FIG. 2 and in side view in FIG. 3; Fig. Q. shows a cross section through a groove located in the back of the laminated core, into which the sheet metal strip, the. _zumKneck the. Package is used, is inserted; Fig. 5 shows a plan view of a package spine with two clips; one of which can be seen from the side. -The production of the new package clips is extremely simple in contrast to the production of the previous clips. T he metal sheet T is fed to the punch. 2 With each stroke of the punching tool 2, two strips 3 and s are punched out. The stop 5 is set so that the strip 3 has the same width as the strip .4. The sheet metal i is moved in the direction of the arrow by means of the slide 6, on which the weight 8 engages via the pull cord 7. 9 pushed until it rests against the stop 5, so that two strips can be punched out again. As shown in FIG. 2, the strips have a simple rectangular cross-section. They are bent up at their ends, as illustrated in FIG. 3, and inserted either smoothly or pre-bent into the grooves To of the back of the laminated core. As Fig. 5 shows, the strip is i! I retained by means of the upsets, i.2 and 1 3, so that he can not come out of the groove To. The clamp 14 is sharply bent at its ends, as indicated at 15. The upsetting z2 ° and 13 have the task of preventing the sheet metal strips from falling out of the grooves, but also relieving the clamps in the axial direction in such a way that essentially only the mass of the sheet metal lying at the ends of the bent clamp ends acts while the pressure of the metal sheets lying in the middle are absorbed essentially by the roughening of the central parts of the sheet metal strips.
