Aus Bleehsegmenten aufgebauter Eisenkern für elektrische Maschinen und Apparate.
Es ist bekannt. den Blechkörper elektrischer Maschinen und Apparate aus einzelnen Blechsegmenten aufzubauen. die fest in einem oder mehreren Befestigungsmitteln im Gehäuse sitzen. Diese Anordnung bringt besonders bei grösseren Maschinen grosse Nachteile, da durch die Erwärmung des Blech- körpers die einzelnen Segmente sich ausdehnen wollen, daran aber durch die feste Anordnung in den Befestigungsmitteln verhindert sind. Dieser Nachteil wird nach der Erfindung unter Verwendung von
EMI1.1
dass diese Segmente an ihrem Träger durch besondere Befestigungsmittel unter Aufrechterhaltung einer Beweglichkeit in tangentialer Richtung gehalten werden.

mitteln je eines Segments eines so ausgebildet werden, dass es keine Beweglichkeit des Segments in tangentialer Richtung zulässt. Dieses eine Befestigungsmittel. das also einen Punkt des Blechpaketes in bezug auf den Träger festlegt, wird mit Vorteil in der Mitte des Segments angeordnet, während die anderen Befestigungsmittel, die ein tangentiales Spiel zulassen, gegen die Enden der Segmente zu angeordnet werden. Um eine bequeme Montage des Blechkörpers zu erzielen, 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.

PATENT-ANSPRÜCHE :
1. Aus Blechsegmenten aufgebauter Eisenkern für elektrische Maschinen und Apparate, bei dem zwischen den einzelnen Blechsegmenten in der Umfangsrichtung ein gewisser Abstand besteht. dadurch gekennzeichnet, dass die Segmente durch besondere Befestigungsmittel i- unter Aufrechterhaltung einer Beweglichkeit in tangentialer Richtung an ihrem Träger gehalten sind.

Iron core made of bleeh segments for electrical machines and apparatus.
It is known. build the sheet metal body of electrical machines and apparatus from individual sheet metal segments. which are firmly seated in one or more fasteners in the housing. This arrangement has major disadvantages, especially in larger machines, since the individual segments want to expand due to the heating of the sheet metal body, but this is prevented by the fixed arrangement in the fastening means. This disadvantage is achieved according to the invention using
EMI1.1
that these segments are held on their support by special fastening means while maintaining mobility in the tangential direction.
Provided however an arbitrary shift
EMI1.2
averaging one segment each can be designed in such a way that it does not allow the segment to move in the tangential direction. This one fastener. that defines a point of the laminated core with respect to the carrier is advantageously arranged in the middle of the segment, while the other fastening means, which allow a tangential play, are arranged against the ends of the segments. In order to achieve a comfortable assembly of the sheet metal body, you can assemble the sheet metal segments beforehand into individual packages and then fasten them with an overlap in their housing as described above.
In machines, this type of fastening can be used for both stands and runners.
EMI1.3
greater uniformity in the magnetic resistance compared to the other layers are offset. sit firmly on the cross pieces tl and is and have a tangential play at the cross piece t2 assigned to their ends. The individual sheets b are advantageously held together by rivets to form sheet packs.
PATENT CLAIMS:
1. Iron core made up of sheet metal segments for electrical machines and apparatus, in which there is a certain distance between the individual sheet metal segments in the circumferential direction. characterized in that the segments are held on their support by special fastening means i- while maintaining mobility in the tangential direction.
