Description
Es ist bekannt, um bei elektrischen Wechselstrommaschinen einen Ständer von großer Starrheit mit einem Minimum von Material- und Arbeitsaufwand zu erhalten, zum Zusammenhalten des in axialer Richtung gepreßten Ständerblechpaketes. Klammern zu verwenden, die zwischen dem Ständerblechpaket und dem . Gehäusemantel eingepreßt sind.It is known to have a large stand in AC electric machines To maintain rigidity with a minimum of material and labor, to hold together of the stator core pressed in the axial direction. Use brackets between the stator core and the . Housing jacket are pressed in.
Erfindungsgemäß sind je zwei solcher Klammem zu einem V-förmigen Segment vereinigt, das unmittelbar oder mittelbar mit dem benachbarten Segment zusammenstößt, so daß von den Segmenten ein besonderer ringartiger Körper _ gebildet wird. Eine derart hergestellte Tragkonstruktion für das Ständerblechpaket ist starrer als die bekannten Tragkonstruktionen mit 'einfachen Klammern; sie unterscheidet sich von diesen hinsichtlich der Starrheit in ähnlicher Weise wie ein Fachwerkträger von einem gewöhnlichen Träger. Die Zeichnung zeigt zwei Ausführungsbeispiele des Erfindungsgegenstandes. Je zwei in an sich bekannter Weise aus Blech gestanzte und gepreßte Klammern sind zu einem V-förmigcn Segment 1 (Fig. 1) vereinigt. Nasen 2 an den Segmenten umgreifen das Ständerblechpaket 3. Bei der Herstellung eines Ständers gemäß dem Ausführungsbeispiel nach Fig. 2 und der zugehörigen Axialsclmittfigur 3 werden vier derartige Rippensegmente so mn den Ständerblechkörper 3, der vorher in bekannter Weise unter Verwendung eines in die Ständerbohrung passend eingeführten Domes in axialer Richtung gepreßt worden ist, gelegt, daß sie (bei/) zusammenstoßen. Über die Segmente i, die somit einen besonderen ringartigen Körper bilden, wird dann ein aus Blech gewalzter offener Ring 4, der den Gehäusemantel bilden kann, gestülpt. Das Ganze wird auf die von der Kollektorherstellung her bekannte Art radial fest zusammengepreßt. Noch in der Preßvorrichtung wird der Ring 4 bei e. (Fig. 2) in an sich bekannter Weise geschweißt und die Segmente 1 an ihren Stoßstellen f durch Schweißen an den Ring 4 angeheftet. Der Ring 4 kann freilich — .statt durch Verschweißen —.auch durch Verschrauben, Vernieten oder Falzen geschlossen werden. Die Hohlräume der Segmente 1 können in an sich bekannter Weise außer zum Durchleiten von Kühlluft zum Hindurchführen von Bolzen 5, die die Lagerschilde auf den Zentrierllachen g des Gehäusemantels 4 festspannen, benutzt werden. .According to the invention, two such brackets are combined to form a V-shaped segment which directly or indirectly collides with the adjacent segment, so that a special ring-like body is formed from the segments. A support structure made in this way for the stator core is more rigid than the known support structures with 'simple brackets; it differs from these in terms of rigidity in a manner similar to that of a lattice girder from an ordinary girder. The drawing shows two exemplary embodiments of the subject matter of the invention. Two brackets each punched and pressed from sheet metal in a manner known per se are combined to form a V-shaped segment 1 (FIG. 1). Noses 2 on the segments encompass the laminated stator core 3. In the manufacture of a stator according to the embodiment of FIG Domes has been pressed in the axial direction, placed that they collide (at /). An open ring 4 rolled from sheet metal, which can form the housing jacket, is then slipped over the segments i, which thus form a special ring-like body. The whole thing is radially tightly pressed together in the manner known from the manufacture of collectors. While still in the pressing device, the ring 4 is at e. (Fig. 2) is welded in a manner known per se and the segments 1 are attached to the ring 4 at their joints f by welding. The ring 4 can of course also be closed by screwing, riveting or folding, instead of by welding. The cavities of the segments 1 can be used in a manner known per se except for the passage of cooling air for the passage of bolts 5, which clamp the end shields on the centering surfaces g of the housing jacket 4. .
Bei der Ausführungsart nach Fig. 4 und S sind die Segmente 1 mit nicht parallelen Stoßflächen ausgeführt. Die Segmente werden hierbei so um den Ständerblechkörper gelegt, daß zwischen benachbarten Segmenten einIn the embodiment according to FIGS. 4 and 5, the segments 1 have non-parallel abutment surfaces executed. The segments are placed around the laminated stator body in such a way that there is one between adjacent segments
