Description

Es ist bekannt, den Blechkörper elektrischer Maschinen und Apparate aus einzelnen Blechs.egmenten aufzubauen, die fest in einem oder mehreren Befestigungsmitteln im Gebluse sitzen. Diese Anordnung bringt besonders bei größeren Maschinen große Nachteile, da durch die Erwärmung des Blechkörpers die einzelnen Segmente sich ausdehnen wollen, daran aber durch die feste An-Ordnung in den Befestigungsmitteln verhindert sind. Dieser Nachteil wird nach der Erfindung dadurch vermieden, daß die Segmente an den Leisten, von denen sie gehalten werden, mit tangentialem Spiel angeordnet werden. Mit besonderem Vorteil· wird hierbei jedes Segment je an einem Befestigungsmittel unverschiebbar gelagert, so daß eine willkürliche Verschiebung der Blechsegmente in nicht voraus bestimmbarer Richtung ausgeschlossen ist. Besonders vorteilhaft ist es, die Segmente in ihrer Mitte fest zu lagern, die Enden dagegen in Befestigungsmitteln mit tangentialem Spiel anzuordnen. Um eine bequeme Montage des Blechkörpers zu erzielen und die tangentiale Verschiebung zu erleichtern, kann man die Blechsegmente vorher zu einzelnen Paketen zusammensetzen und diese dann mit Überlappung in ihrem Gehäuse, wie oben beschrieben, befestigen. Bei Maschinen kann diese Befestigungsart sowohl für Ständer als auch für Läufer verwendet werden.It is known, the sheet metal body of electrical machines and apparatus from individual Build up sheet metal segments that are firmly attached to one or more fasteners in the blouse sit. This arrangement has major disadvantages, especially with larger machines, because the individual segments want to expand due to the heating of the sheet metal body, but because of the fixed arrangement are prevented in the fastening means. This disadvantage is avoided according to the invention in that the segments arranged with tangential play on the bars by which they are held will. It is particularly advantageous here that each segment is attached to a fastening means immovably mounted, so that an arbitrary displacement of the sheet metal segments is excluded in a direction that cannot be determined in advance. It is particularly advantageous to store the segments firmly in their middle, the ends, however, in fasteners to arrange tangential play. To achieve a convenient assembly of the sheet metal body and to facilitate the tangential movement, you can adjust the sheet metal segments beforehand assemble individual packages and then overlap them in their housing, such as as described above. For machines, this type of fastening can be used for both stands as well as for runners.

Die Figur zeigt in einem Ausführungsbeispiel (Fig. 1) einen Teil eines Ständerblechkörpers einer elektrischen Maschine. Der Blechkörper ist hier an T-förmigen Querstücken t1; t2, ts befestigt, die am S tändergehäuse, das der besseren Übersicht wegen nicht mitgezeichnet ist, sitzen. Die Mitte der einzelnen Bleche sitzt fest in dem Querstück tv während die Enden der Bleche in den Querstücken t1 und ts mit tangentialem Spiel· angeordnet sind. In dem Ausführungsbeispiel überlappen sich die Teilpakete p. Die einzelnen Bleche δ werden in bekannter Weise vorteilhaft durch Nieten η zusammengehalten.In one embodiment (FIG. 1), the figure shows part of a laminated stator of an electrical machine. The sheet metal body is here on T-shaped cross pieces t 1; t 2 , t s attached, which sit on the stator housing, which is not shown for the sake of clarity. The center of the individual metal sheets is firmly seated in the cross piece t v, while the ends of the metal sheets are arranged in the cross pieces t 1 and t s with tangential play. In the exemplary embodiment, the subpackets p overlap. The individual sheets δ are advantageously held together in a known manner by rivets η.

In Fig. 2 der Zeichnung ist noch ein Ausführungsbeispiel für die Anwendung der Erfindung auf einen Läufer dargestellt, bei dem für die einzelnen Teile dieselben Bezeichnungen wie in Fig. 1 gewählt wurden.In Fig. 2 of the drawing is another embodiment for the application of the invention shown on a runner, in which the same designations for the individual parts as in Fig. 1 were chosen.
