Description

Man kann bei EletktrizitätszählernX namentlich solchen mit schwerem Anker, die Lager magnetisch entlasten. Meist begnügt man sich mit einer teilweisen Entlastung, damit der Anker noch sicher geführt ist. Nachteilig ist, daß das zur Entlastung dienende Magnetsystem schon bei geringen Auswanderungen der Ankerwelle aus der Symmetrielage radiale Kräfte ausübt, die die Zählerlager zusätzlich beanspruchen. In the case of electricity meters, one can especially use those with heavy Anchors that magnetically relieve the bearing. Usually one is content with a partial one Relief so that the anchor is still safely guided. The disadvantage is that the Relief-serving magnet system even with minor emigration of the armature shaft exerts radial forces from the symmetry position, which additionally stress the meter bearings.

Die Erfindung nutzt diese sonst störenden radialen Kräfte nutzbringend zur Lagerentlastung aus. The invention makes beneficial use of these otherwise disruptive radial forces to relieve the load.

Erfindungsgemäß ist die Ankerwelle zum entlastenden Magnetsystem derart unsymmetrisch angeordnet, daß die vom Magnetsystem auf die Welle ausgeübten Radialkräfte den durch Trieb- und Bremsmagnete des Zählers auf den Anker ausgeübten Radialkräften entgegenwirken. Dadurch werden die Zählerlager wenigstens teilweise auch radial entlastet; insbesondere ist es möglich, für einen bestimmten Belastungspunkt des Zählers die Radialkräfte zum Verschwinden zu bringen.According to the invention, the armature shaft is such for the relieving magnet system arranged asymmetrically that the radial forces exerted on the shaft by the magnet system the radial forces exerted on the armature by the meter's drive and brake magnets counteract. As a result, the counter bearings are at least partially also radial relieved; in particular, it is possible for a specific load point of the Counter to make the radial forces disappear.

Die Erfindung wird an Hand der Zeichnung näher erläutert. The invention is explained in more detail with reference to the drawing.

Auf einer Ankerwelle I eines Elektrizitätszählers ist ein zylindrischer Stabmagnet 2 höchster Leistung befestigt. Betriebsmäßig darunter ist ein hohlzylindrischer Magnet 3 am Zälhlergestell fest angeordnet. Beide Magnete 2, 3 kehren sich gleichnamigen Polen N zu und entlasten durch Abstoßung teilweise das Unterlager. Die Ankerwelle 1 mit dem Magnet 2 ist etwas unsymmetrisch zum Magnet 3 gelagert. Dadurch ergibt sich eie im Sinne des Pfeiles 4 wirkende Radialkraft. Diese Radialkraft wirkt der Resultierenden 67, Fig. 2, der von einem Triebmagnet 7 und einem Bremsmagnet 6 auf den Anker 5 ausgeübten Radialkräfte 60, 70 entgegen. In Fig. 2 sind die Teile 6, 7 diametral angeordnet. Sind sie um9o0 räumlich versetzt, dann ergibt sich ein Kräfteplan gemäß der Fig. 3. On an armature shaft I of an electricity meter is a cylindrical one Fixed bar magnet 2 of the highest power. Operationally underneath is a hollow cylindrical one Magnet 3 fixed on the counter frame. Both magnets 2, 3 are reversed with the same name Poles N to and partly relieve the sub-camp through repulsion. The armature shaft 1 with magnet 2 is mounted somewhat asymmetrically to magnet 3. This results in radial force acting in the direction of arrow 4. This radial force acts the Resulting 67, Fig. 2, of a drive magnet 7 and a brake magnet 6 on the armature 5 counteracts radial forces 60, 70. In Fig. 2 the parts 6, 7 arranged diametrically. If they are spatially offset by 90, then a plan of forces results according to FIG. 3.
