Description

Lagerung für Läufer elektrischer 1VIaschinen großer Baulänge. Bei manchen elektrischen Maschinen wird die Länge des Läufers im Verhältnis zum Durchmesser sehr groß. Die Folge ist, daß die Umdrehungszahl wegen der zu befürchtenden Schwingungen des umlaufenden Teiles niedrig gehalten werden muß und infolgedessen die Ausnutzung der Maschine sehr ungünstig ist.Bearing for rotors of large electrical machines. at Some electrical machines have the length of the rotor in relation to the diameter very large. The result is that the number of revolutions because of the vibrations to be feared of the rotating part must be kept low and consequently the utilization the machine is very inconvenient.

Diesen Mangel beseitigt die Erfindung dadurch, dlß der Läufer oder seine Welle außer in den üblichen seitlichenLagern noch in einem oder mehreren weiteren Lagern abgestützt wird, die mit ihren Außenringen an der Innenwand der Ständerbohrung oder eines anderen festen Maschinenteils anliegen.The invention eliminates this deficiency in that the runner or its shaft in addition to the usual side bearings in one or more other Bearings is supported with their outer rings on the inner wall of the stator bore or another fixed part of the machine.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Die Läuferwelle i, die in bekannter Weise rechts und links in beliebigen Lagern gelagert ist, trägt in der Mitte ein zusätzliches Lager 5, das mit einem Stützring 6 an der Innenwand der Bohrung des Ständers 3 fest anliegt. Je nach Bedarf und nach der Baulänge können mehrere derartige Stützlager bei einer Maschine vorgesehen werden. Die Folge dieser Zwischenlagerung ist, daß die Welle und damit der Läufer nicht mehr schwingen können. Es wird also durch Anwendung der Erfindung möglich, sehr lange elektrische Maschinen zu bauen, ohne den Luftspalt 4. vergrößern zu müssen.The rotor shaft i, which in a known manner on the right and left in any Storage is stored, carries in the middle an additional bearing 5, which is with a Support ring 6 rests firmly against the inner wall of the bore of the stand 3. As required and depending on the overall length, several such support bearings can be provided on a machine will. The consequence of this intermediate storage is that the shaft and thus the rotor can no longer vibrate. It is thus possible through application of the invention to build very long electrical machines without having to enlarge the air gap.

Der Läufer selbst wird bei dieser Ausbildung der Maschine in einzelne Anker z geteilt, und zwar wird immer ein Anker mehr sein, als Zwischenlager vorhanden sind. Die Lagerringe müssen gegen das aktive Eisen und die Wicklungen genügend isoliert sein. Im übrigen kommt es aber auf die Bauart der Lager als solche nicht an.The runner itself is in this training the machine in individual Anchor z divided, and there will always be one more anchor than intermediate storage are. The bearing rings must be sufficiently insulated from the active iron and the windings be. For the rest, however, it does not depend on the type of bearing as such.
