Description

Geschlossene elektrische Maschine mit Ölfüllung. Bei Maschinen mit Ölfüllung findet beim Eindringen des Öles in die als Isolation dienenden Glimmerteil'e des Stromwenders eine Karbon,isierung derselben statt. Der Glimmer verliert dadurch seine Isolationsfähigkeit, so daß bald Funkenbildungen auftreten, die die Maschine nach und nach jurybrauchbar machen,. Um diesem Übelstand abzuhelfen, werden nach der Erfindung der Stromwender, die Schleifringe und dergleichen Maschinenteile durch Anordnung derselben in einer besonderen, abgekapselten Kammer von der Berührung mit der isolierenden Flüssigkeit ferngehalten.Closed electric machine with oil filling. For machines with Oil filling takes place when the oil penetrates into the mica parts serving as insulation of the commutator a carbonization takes place. This causes the mica to lose its ability to isolate, so that sparks soon occur which the machine gradually make them usable by the jury. In order to remedy this malady, are after the invention of the commutator, the slip rings and the like machine parts through Placement of the same in a special, encapsulated chamber from the touch kept away with the insulating liquid.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Längsschnitt dargestellt.In the drawing, an embodiment of the invention is in longitudinal section shown.

Die Maschine besteht aus dem Ständer 6, in dem der Läufer 5 auf der Welle 3 in den Lagern .4 gelagert ist.The machine consists of the stand 6, in which the rotor 5 on the Shaft 3 is supported in bearings .4.

Das Gestell des Motors ist mit einem Zylinder 8 versehen, indem ein durch eine Feder 1o beeinfiußter Kolben g eingesetzt ist. 7 ist eine Verbindungsöffnung zwischen dem Zylinder 8 und dem Motor 5, 6. Wird das Innere des Motors mit Öl gefüllt, so dringt dieses durch die Öffnung 7 auch in den Zylinder 8 und bewegt den Kolben: g unter Zusammenpressen der Feder to derart, daß ohne Rücksicht auf den Außendruck der innere Druck des Öles infolge der Wirkung der Feder to denr äußeren Druck immer übersteigen wird'.The frame of the engine is provided with a cylinder 8 by a Piston g, influenced by a spring 10, is inserted. 7 is a communication port between cylinder 8 and engine 5, 6. If the inside of the engine is filled with oil, so this penetrates through the opening 7 into the cylinder 8 and moves the piston: g with compression of the spring to in such a way that regardless of the external pressure the internal pressure of the oil due to the action of the spring to the external pressure always will exceed '.

Wenn die Maschine unter Wasser in einer beträchtlichen Tiefe arbeiten soll, so wird zwecks Verhütung der Energieverjuste durch die Reibung des Läufers 5 itn Öl eine Ventilstopfbüchsenvorrichtung angebracht, bei welcher das Öl in, dem Motor einem hohen Außendruck nicht ausgesetzt ist.When the machine is working underwater to a considerable depth is to be used in order to prevent energy losses due to the friction of the rotor 5 itn oil a valve stuffing box device attached, in which the oil in, the Engine is not exposed to high external pressure.

Um nun den Stromwender, die Schleifringe und die dazugehörigen empfindlichen Teile gegen Berührung mit der isolierenden Flüssigkeit zu schützen, werden diese nach der Erfindung in einer besonderen Luftkammer 12 des Maschinengehäuses untergebracht, die gegen das Eindringen des Öles abgedichtet und deren Luft gegebenenfalls ;furch einen Hahn 16 abgelassen werden kann.Now about the commutator, the slip rings and the associated sensitive ones These are to protect parts against contact with the insulating liquid housed according to the invention in a special air chamber 12 of the machine housing, which are sealed against the ingress of oil and their air, if necessary; furch a tap 16 can be drained.

1q. ist ein Entlüftungshahn und 15 ein Manometer. Durch den Hahn 17 wird das Gehäuse mit Öl gefüllt. Die Wel.len#bohrung 18 dient zur Verlegung der Leitungen.1q. is a vent valve and 15 is a pressure gauge. The housing is filled with oil through the valve 17. The shaft hole 18 is used to lay the lines.
