Description
Nutenkeile für elektrische Maschinen werden bisher in der Weise hergestellt, daß trapezförmig geschnittene Bleche geschichtet miteinander durch gegebenenfalls nicht ma-S gnetisierbare Stifte vernietet und darauf mit einer Isolierschicht umwickelt oder umpreßt werden. Diese Herstellungsart ist umständlich und teuer.Slot wedges for electrical machines have so far been produced in such a way that trapezoidal cut sheets layered with one another by possibly not ma-S Gnetisable pins riveted and then wrapped with an insulating layer or overmolded will. This type of production is cumbersome and expensive.
Es ist ferner vorgeschlagen worden, Nutenkeile dadurch herzustellen, daß Bleche in einer der Länge des Keiles entsprechenden Anzahl geschichtet, in Reihen nebeneinander gruppiert und darauf mit Isoliermaterial umpreßt werden. Die einzelnen Keile werden dann durch Aufschneiden der Isolationsschicht zwischen den Blechen hergestellt. Diese Art der· Herstellung der Nutenkeile bietet fabrikationstechnische Schwierigkeiten, die die praktische Ausführung unmöglich machen. Die an den Flanken der Keile erforderliche Isolierschicht ist sehr dünn. Es ist nun sehr schwierig, die geschichteten Bleche in der richtigen Entfernung nebeneinander während der Umpressung mit Isoliermaterial so gleichmäßig zu distanzieren, daß bei dem nachfolgenden Aufschneiden der trennenden Isolierschicht diese nicht zerstört wird. Geringe Verschiebungen der geschichteten Bleche zueinander erschweren die Fabri-.It has also been proposed to produce slot wedges in that sheets in layered in a number corresponding to the length of the wedge, in rows next to each other are grouped and then pressed around with insulating material. The individual wedges are then made by cutting open the insulation layer between the sheets. This type of · production of slot wedges offers manufacturing difficulties that make practical implementation impossible do. The insulating layer required on the flanks of the wedges is very thin. It is now very difficult to juxtapose the layered sheets at the correct distance to be so evenly spaced during the encapsulation with insulating material that when the separating insulating layer is subsequently cut open, it is not destroyed will. Slight displacements of the layered sheets to one another make the factory more difficult.
kation, geben viel Ausschuß und Nachisolationen. cation, give a lot of waste and post-isolation.
Gegenstand der Erfindung ist nun ein Verfahren zur Herstellung von Nutenkeilen, bei dem diese Nachteile dadurch beseitigt werden, daß aus mit Isolierstoff umpreßten und in einer der Länge des Keiles entsprechenden Anzahl geschichteten Blechstreifen gebildeten Stangen trapezförmige Keile durch zwei unter einem Winkel die Bleche quer teilende Schnitte ohne Abfall geschnitten werden. Die Blechstreifen werden zweckmäßig durch eine Zunderschicht, Papier oder Lack isoliert.The invention now relates to a method for producing slot wedges which these disadvantages are eliminated in that from encapsulated with insulating material and in formed a number of layered sheet metal strips corresponding to the length of the wedge Rods of trapezoidal wedges through two cuts that cross the sheets at an angle can be cut without waste. The metal strips are expediently covered by a layer of scale, Paper or paint isolated.
In der Zeichnung ist in Abb. 1 ein gemäß dem Verfahren hergestellter Stab α dargestellt, der aus den nebeneinandergeschichteten Blechstreifen b besteht, die mit der Isolierschicht c umgeben sind. Die Isolierschicht kann eine Umpressung mit Hartpapier (Bakelit) oder mit einem gleichwertigen Isolierstoff bekannter Art sein. Um einen besseren Zusammenhalt der Blechlamellen zu sichern, ist es zweckmäßig, die Blechstreifen an beiden Längskanten mit Aussparungen d zu versehen, die beim Aneinanderreihen der Blechstreifen Nuten bilden und mit dem Preßmaterial ausgefüllt werden, wie aus Abb. 2 ersichtlich, die einen Querschnitt durch einen fertigen Keil darstellt. Die Anzahl und die Form der Aussparungen ist ganz beliebig. Aus einem gemäß dem Verfahren hergestellten Stab werden durch zwei unter einem Winkel verlaufende Querschnitte trapezförmige Keile ohne Abfall herausgeschnitten, wie in Abb. ι dargestellt.In the drawing, in Fig. 1, a rod α produced according to the method is shown, which consists of the sheet-metal strips b stacked next to one another and surrounded by the insulating layer c. The insulating layer can be pressed with hard paper (Bakelite) or with an equivalent insulating material of a known type. In order to ensure better cohesion of the sheet metal lamellas, it is useful to provide the sheet metal strips on both longitudinal edges with recesses d , which form grooves when the sheet metal strips are lined up and are filled with the pressing material, as shown in Fig. 2, which shows a cross section through a Represents finished wedge. The number and shape of the recesses is entirely arbitrary. Trapezoidal wedges without waste are cut out of a rod produced according to the method by means of two cross-sections running at an angle, as shown in Fig. Ι.
