Description

Vorrichtung zum genauen konzentrischen Einstellen des Luftspaltes bei elektrischen Maschinen. Besonders bei Drehstrommotoren ist es zur Verbesserung des cos y erwünscht, den Luftspalt klein zu halten. Um dies zu ermöglichen, ist eine genaue konzentrische Einstellung desselben notwendig.Device for precise concentric adjustment of the air gap in electrical machines. It is particularly useful for three-phase motors des cos y, it is desirable to keep the air gap small. To make this possible is an exact concentric adjustment of the same is necessary.

Gegenstand der Erfindung ist nun eine Vorrichtung, durch die bei Maschinen mit Lagerschildausführung in einfacher Weise der Luftspalt eingestellt werden kann. An Hand der beiliegenden Abbildungen soll ein Ausführungsbeispiel beschrieben werden. Es bedeutet .cr die Welle der Maschine, a den Teil des Lagerschildes, der an das Ständergehäuse angeschraubt wird, und der bei den üblichen Ausführungen im Gegensatz zu unserer Erfindung mit dem Lager aus einem Stück hergestellt wird. An diesen Teil wird mit den Schrauben d ein Ring c festgeschraubt, der das Lager l trägt. Am Teil a befinden sich außerdem drei oder mehr angegossene Vorsprünge b, in die die Schrauben e eingebracht werden. Der Vorgang beim Montieren und Einstellen der Welle ist folgender: Der Ring c wird zuerst mit den Schrauben d lose befestigt, so daß ein Verschieben desselben mit Hilfe der Einstellschrauben e möglich ist. Es muß entsprechend dieser Verschiebung die Bohrung 'für die Schraubend im Ringe c etwas größer gemacht werden. Ist der Luftspalt durch Verschiebung der Muttern f und h genau eingestellt, so werden die Schraubend fest angezogen. Das zweite Lager der Maschine muß mit einer ähnlichen Vorrichtung versehen werden.The invention now relates to a device by means of which the air gap can be adjusted in a simple manner in machines with a bearing shield design. An exemplary embodiment is to be described on the basis of the accompanying figures. It means .cr the shaft of the machine, a the part of the end shield which is screwed to the stator housing and which, in contrast to our invention, is made in one piece with the bearing in the usual designs. A ring c, which carries the bearing l, is screwed onto this part with the screws d. On part a there are also three or more molded projections b into which the screws e are inserted. The procedure for assembling and adjusting the shaft is as follows: The ring c is first loosely fastened with the screws d so that it can be moved using the adjusting screws e. The hole 'for the screw in the ring c must be made somewhat larger in accordance with this shift. If the air gap is set precisely by moving the nuts f and h , the screws are tightened firmly. The second bearing of the machine must be fitted with a similar device.
