Description
Läufer mit Blechringen für sclmellaufende elektrische Maschinen. Die Erfindung betrifft Läufer für schnell laufende elektrische Maschinen, die aus einer Nabe und mit dieser verbundenen Blechen, zum Beispiel Blechsegmenten bestellen. Bei derartigen Läufern besteht bei grosser Ge schwindigkeit und grossem Läuferdurchmes ser die Gefahr, dass die Fliehkräfte der Bleche nicht mehr aufgenommen werden kön nen. Diese Gefahr wird nach der Erfindung dadurch vermieden, dass zwischen die Bleche und die Nabe ein Tragring aus hochwertigem Material geschaltet wird, an dem die Bleche befestigt werden.
Zur Befestigung werden dabei zweckmässig schwalbenschwanzför- mige Einlagen verwendet.
Die Erfindung ist in einem Ausführungs- beispiel in der Zeichnung dargestellt. Mit n ist die Nabe des Läufers mit den Armen a bezeichnet, b sind Blechsegmente. die mit der Nabe verbunden werden sollen.
'Nach der Erfindung ist zwischen beiden Teilen eiri Zwischenring z aus hochwertigem Material eingeschaltet, der die Blechsegmente b trägt. Diese sind durch keilförmige Zwischenstücke I,
mit rlem Tragring N-erbunden. All 'Stelle der Blechsegmente hönneii selbstverständlich auch ungeteilte Blf-elie verwendet werden.
Rotor with sheet metal rings for high-speed electrical machines. The invention relates to rotors for high-speed electrical machines that order sheet metal segments, for example, from a hub and metal sheets connected to it. With such runners, at high speeds and large runner diameters, there is the risk that the centrifugal forces of the sheets can no longer be absorbed. According to the invention, this risk is avoided in that a support ring made of high quality material is connected between the metal sheets and the hub, to which the metal sheets are attached.
Dovetail-shaped inserts are expediently used for fastening.
The invention is shown in an exemplary embodiment in the drawing. The hub of the rotor with the arms a is denoted by n, and b are sheet metal segments. to be connected to the hub.
According to the invention, an intermediate ring z made of high quality material is inserted between the two parts, which carries the sheet metal segments b. These are by wedge-shaped spacers I,
N-bound with rlem support ring. Of course, undivided sheets can also be used in all of the sheet metal segments.
