Description

Es ist bekannt, die Lager senkrechter Wellen von Maschinen und auch von Instrumenten oder Apparaten durch magnetische Kräfte zu entlasten. Die bekannten magnetischen Aufhängungen der Läufer von Elektrizitätszählern und ähnlichen Instrumenten oder Apparaten führen jedoch meist zu Haltepunkten an unerwünschten Stellungen des Läufers, oder sie sind zu aufwendig. Die Erfindung schafft demgegenüber eine magnetische Aufhängung, die diese Nachteile vermeidet. It is known the bearings of vertical shafts of machines and also to relieve instruments or apparatus by magnetic forces. The known magnetic suspensions for the rotors of electricity meters and similar instruments or apparatuses, however, usually lead to breakpoints at undesired positions of the Runner, or they are too expensive. In contrast, the invention creates a magnetic one Suspension that avoids these disadvantages.

Die Erfindung besteht darin, daß die Welle mehrere (z. B. fünf) axial magnetisierte innere Ringmagnete mit abwechselnder Polarität trägt; die durch dünne magnetisierbare Scheiben getrennt sind, deren Außendurchmesser größer als der der Ringmagnete ist, und denen eine entsprechende Anzahl konzeritrisch zu den inneren Ringmagneten auf gleicher Höhe liegender entgegengesetzt gepolter äußerer Ringmagnete zugeordnet ist, die gleichfalls durch dünne magnetisierbare Scheiben getrennt sind, deren Innendurchmesser kleiner als der Innendurchmesser der äußeren Ringmagnete ist. The invention is that the shaft several (z. B. five) axially carrying magnetized inner ring magnets with alternating polarity; those through thin magnetizable disks are separated, the outer diameter of which is greater than that of the Is ring magnets, and a number corresponding to the inner ones Ring magnets at the same height as oppositely polarized outer ring magnets is assigned, which are also separated by thin magnetizable disks, whose inner diameter is smaller than the inner diameter of the outer ring magnets is.

Zur Erläuterung der Erfindung ist in der Zeichnung ein Ausführungsbeispiel einer solchen magnetischen Aufhängung der Welle eines Elektrizitätszählers angedeutet. To explain the invention, an exemplary embodiment is shown in the drawing such a magnetic suspension of the shaft of an electricity meter indicated.

Die Welle 1, die oben und auch unten von einem Stiftlager 2 zentriert ist, trägt eine Anzahl, beim dargestellten Ausführungsbeispiel fünf, Ringmagnete 3, die axial magnetisiert und mit abwechselnder Polung, wie angedeutet, angeordnet sind. Zwischen diesen Magneten und oberhalb und unterhalb des Magnetpaketes sind dünne Scheiben 4 aus magnetisierbarem Werkstoff, beispielsweise Weicheisen, angeordnet, deren Außendurchmesser größer ist als der Durchmesser der Ringmagnete3, so daß sie über diese überstehen. Diese Anordnung ist innerhalb einer gleichen Anzahl von Ringmagneten 5 angeordnet, die ebenfalls mit abwechselnder Polung axial magnetisiert sind. Die Polung der auf gleicher Höhe befindlichen Ringmagnete 3 und der sie umgebenden Ringmagnete 5 ist dabei, wie angegeben, unterschiedlich gewählt. Zwischen den Ringmagneten 5 und zu beiden Seiten dieses Paketes sind ebenfalls dünne Scheiben 6 aus magnetisierbarem Werkstoff, z. B. Weicheisen, vorgesehen, deren Innendurchmesser kleiner ist als der Durchmesser der Ringmagnete 5. Die Scheiben 4 und 6 stehen sich daher mit geringem Luftspalt gegenüber. Auf diese Weise wird eine starke Konzentrierung des magnetischen Feldes und ein großes Potentialgefälle in Achsrichtung der Welle 1 erzielt. The shaft 1, which is centered at the top and also at the bottom by a pin bearing 2 is, carries a number, five in the illustrated embodiment, ring magnets 3, which are axially magnetized and arranged with alternating polarity, as indicated are. Between these magnets and above and below the magnet package are thin disks 4 made of magnetizable material, for example soft iron, arranged, whose outer diameter is larger than the diameter of the ring magnets3, so that they survive over this. This arrangement is within an equal number of ring magnets 5 arranged, which are also axially magnetized with alternating polarity. the Polarity of the ring magnets 3 located at the same height and the ring magnets surrounding them 5 is different, as indicated chosen. Between the ring magnets 5 and on both sides of this package are also thin disks 6 made of magnetizable Material, e.g. B. soft iron, provided whose inner diameter is smaller than the diameter of the ring magnets 5. The disks 4 and 6 are therefore with little Air gap opposite. This way there will be a strong concentration of the magnetic Field and a large potential gradient in the axial direction of the shaft 1 achieved.

Dadurch ergibt sich eine besonders große Haltekraft für die Aufhängung der Welle.This results in a particularly large holding force for the suspension the wave.

Auf die Magnete schwächend wirkende Temperaturerhöhungen bewirken nur ein geringes Sinken des Läufers des Zählers. Demzufolge können auch Magnete aus Oxydmaterial mit sehr großer Haltekraft, aber auch hohem Temperaturkoeffizienten Verwendung finden. Cause temperature increases that have a weakening effect on the magnets only a slight decrease in the runner of the counter. As a result, magnets can also Made of oxide material with a very high holding force, but also a high temperature coefficient Find use.
