Description

Spulenkörper für Eisenkerne mit rechteckigem Querschnitt, insbesondere für Hauptpole elektrischer Gleichstrommaschinen, sind meist aus einem Stück gefertigt und haben ein etwa U-förmiges Profil. Als Material wird meist mit Lack getränktes Papier, Preßspan oder mit Isolierstoff beklebtes Metall verwendet. Um den Spulenkörper auf den Polschaft aufziehen zu können, muß der Pol mit abnehmbarem Joch oder Polschuhen ausgeführt werden. Außerdem ist die Anfertigung des Spulenkastens aus einem Stück ziemlich kostspielig.Bobbins for iron cores with a rectangular cross-section, in particular for main poles of electrical DC machines, are usually made from one piece and have an approximately U-shaped profile. The material used is usually something impregnated with varnish Paper, pressboard or metal glued with insulating material is used. Around the bobbin To be able to pull it up on the pole shaft, the pole must have a removable yoke or pole pieces are executed. In addition, the bobbin case is made from one piece quite expensive.

Die Erfindung beseitigt diese Nachteile. Erfindungsgemäß besteht der Spulenkasten mit etwa U-förmigem Profil aus zwei U-förmig gebogenen Stirnstücken und zwei geraden, mit ihren Enden in die Schenkelteile der Stirnstücke eingeschalteten Seitenstücken und sitzen die Enden der Stirnstücke wenigstens mit Teilen ihrer Querechnittsfläche auf dem Eisenkern auf.The invention overcomes these disadvantages. According to the invention, the Coil box with an approximately U-shaped profile made of two U-shaped end pieces and two straight ends connected to the leg parts of the end pieces Side pieces and sit the ends of the end pieces at least with parts of their cross-sectional area on the iron core.

Zur näheren Erläuterung der Erfindung dient das in der Zeichnung dargestellte Ausführungsbeispiel. Der Spulenkasten für den Hauptpol i einer Gleichstrommaschine besteht aus zwei U-förmig gebogenen Stirnstücken 2 und zwei geraden Seitenstücken 3. Die Seitenstücke sind mit ihren Enden 4 in die Schenkelteile 5 der Stirnstücke 2 eingeschachtelt, so daß sich zwischen den beiden Bauteilen ein Kriechweg 6 ergibt. Die Enden der Stirnfläche sitzen mit ihren Querschnittflächen 7 auf den Stirnflächen des Pols i auf. Infolge der U-förmigen Gestaltung der Stirnstücke 2 werden an den Stirnflächen des Pols Kanäle 8 gebildet, durch die die Kühlluft streichen kann. Während die Seitenstücke zweckmäßig aus dünnen Preßspanstreifen zur U-Form gebogen werden, bestehen die Stirnstücke vorteilhaft aus Preßstücken.The illustration shown in the drawing serves to explain the invention in greater detail Embodiment. The coil box for the main pole i of a DC machine consists of two U-shaped curved end pieces 2 and two straight side pieces 3. The ends 4 of the side pieces are in the leg parts 5 of the end pieces 2 nested, so that there is a creepage path 6 between the two components. The ends of the end face sit with their cross-sectional areas 7 on the end faces of the pole i. As a result of the U-shaped design of the end pieces 2 are at the Formed end faces of the pole channels 8 through which the cooling air can pass. While the side pieces are suitably bent to a U-shape from thin strips of pressboard are, the end pieces advantageously consist of pressed pieces.

Die Erfindung bietet den Vorteil, daß der Spulenkasten aus einfach zu fertigenden Bauteilen zusammengesetzt und damit die Herstellung wesentlich verbilligt werden kann. Außerdem können die Pole bzw. die Polschuhe und Polbleche aus einem Stück gefertigt werden.The invention has the advantage that the bobbin case is simple Assembled to be manufactured components and thus the production significantly cheaper can be. In addition, the poles or the pole shoes and pole sheets from one Piece to be manufactured.
