Description

Wellenstütze für elektrische Maschinen Elektrische Maschinen, die auf beweglichen Anlagen, beispielsweise auf Schiffen, aufgestellt sind, sind während des Transportes erheblichen mechanischen Stößen ausgesetzt. Am meisten gefährdet ist dabei die Welle, insbesondere wenn der Lagerabstand verhältnismäßig groß ist. Sie kann schon aus wirtschaftlichen Gründen nicht immer so stark bemessen werden, daß beim Auftreten von Stößen ein Streifen des Läuferblechpaketes am Ständerblechpaket vermieden wird.Shaft support for electrical machines Electrical machines that are set up on movable systems, for example on ships, are during exposed to considerable mechanical shocks during transport. Most at risk is the shaft, especially if the bearing spacing is relatively large. For economic reasons alone, it cannot always be measured so strongly that when bumps occur, a strip of the laminated rotor core on the laminated stator core is avoided.

Die Erfindung beseitigt diese Schwierigkeiten. Erfindungsgemäß ist eine Scheibe in größtmöglicher Nähe der Mitte zwischen den Wellenlagern und des Läufers innerhalb eines am Maschinengehäuse fest angeordneten Ringes auf der Welle befestigt, wobei der Luftspalt zwischen Ring und Scheibe kleiner ist als der Luftspalt zwischen dem Ständer und dem Läufer.The invention overcomes these difficulties. Is according to the invention a washer as close as possible to the center between the shaft bearings and the Rotor within a ring fixedly arranged on the machine housing on the shaft attached, the air gap between the ring and disc is smaller than the air gap between the stand and the runner.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Sie zeigt schematisch eine elektrische Maschine im Längsschnitt.An embodiment of the invention is shown in the drawing. It shows schematically an electrical machine in longitudinal section.

Die Welle 1 ist mittels der Lager 2 und 3 in dem Gehäuse 4 gelagert. 5 ist der Läufer, 6 der Ständer und 7 der Kommutator. Zwischen dem Läufer 5 und dem Kommutator 7 ist eine Scheibe 8 auf der Welle befestigt, und zwar innerhalb eines an dem Gehäuse fest angeordneten Ringes 9. Zwischen der Scheibe 8 und dem Ring 9 ist ein Luftspalt 10 vorhanden, der kleiner ist als der Luftspalt 11 zwischen dem Läufer 5 und dem Ständer 6.The shaft 1 is supported in the housing 4 by means of the bearings 2 and 3. 5 is the rotor, 6 is the stator and 7 is the commutator. Between the runner 5 and the commutator 7, a disk 8 is attached to the shaft, inside a ring 9 fixedly arranged on the housing. Between the disk 8 and the Ring 9, there is an air gap 10 which is smaller than the air gap 11 between the rotor 5 and the stator 6.

Beim Auftreten eines Stoßes schleift die Scheibe 8 kurzzeitig an dem Ring 9, wodurch vermieden wird, daß sich die Welle so weit durchbiegt, daß der Läufer an dem Ständer aufliegt. Mit der Begrenzung der Durchbiegung ergibt sich gleichzeitig eine Begrenzung der Beanspruchung der Welle. Diese kann daher so bemessen werden, wie sie für Aufstellung der Maschine an einem festen Ort erforderlich ist.When an impact occurs, the disc 8 briefly rubs against the Ring 9, which prevents the shaft from bending so far that the rotor rests on the stand. With the limitation of the deflection results at the same time a limitation of the stress on the shaft. This can therefore be measured in such a way that as required for setting up the machine at a fixed location.
