Description

Es ist bekannt, Ziffernrollen für Zählwerke von Elektrizitä tszä'hlern od. dgl. in einem Stück her- zustellen, insbesondere zu spritzen. Bei diesen Rollen hat die Nabenböhltuig an allen Stellen gleichen Durchmesser. Dadurch kann, namentlich wenn Staub eindringt, die Reibung der Rolle erhöht Nverden.@ Infolge unvermeidlicher Abweichungen bei der Massenfertigung oder bei geringfügigem Ver- ziehen des Rollenkörpers kann sidli die Rolle sogar auf der Achse festklemmen oder ihre gute Führung verlieren. Die Erfindung vermeidet diesen Mangel. Er- findungsgemäß hat die laternenartig durchbrochene Nabeder Rolle zwei durch einen erlveiterten lfittel- b'ereich getrennte Laufflächen. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung in zwei versdiiedenen Ansichten (Fig. i und 2) dargestellt. Eine Ziffernrolle mit dem Ziffernkranz i, der Schaltlücke 2 und der Verzalintillg 3 hat eine laternenartig durchbrochene Nabe 4, die durch Speichen j mit dem Ziffernkranz verbunden ist. Die alle hat an den Enden zwei Laufflächen 6i, 7. die durch einen erweiterten Mittelbereich8 voneinander getrennt sind. Dicser Bereich miindet in die Öff- nungen 9 der Laterne. Durch diese Öffnungen können bei der Rollenherstellung entsprechende Schieber der Form grc^ifen. die den erweiterten Zwischenraum 8 ausfüllen. De Ziffern sind auf den Ziffernkranz i aufgedruckt und der Druck durch einen radial vorspringenden Sclltitzraii<I io ge- schützt. Eine solche ]Zolle bietet folgende Vorteile. Durch die in Abstand angeordneteil schirealen Lauf- fläcbell Ei, 7 erhält die trolle eine gute Führung. Auch wird ihre Reibung verringert. Etwa zwischen Lauffläche und Achse eingedrtingeiler Staub kann nach innen oder außen abwandern. It is known to use dials for counters from Electricity counters or the like in one piece deliver, in particular to inject. With these The hub screed has roles in all places same diameter. This allows, in particular if dust gets in, the friction of the roller increases Nverden. @ As a result of inevitable deviations at mass production or in the case of minor pulling the roller body can even sidli the roller clamp on the axis or their good guidance lose. The invention avoids this deficiency. He- according to the invention, the lantern-like openwork At the top of each roll two an extended middle Area with separate running surfaces. An embodiment of the invention is in Drawing in two different views (Fig. I and 2). A number scroll with the number wreath i, the Switching gap 2 and the Verzalintillg 3 has one Lantern-like openwork hub 4, which by Spokes j is connected to the number ring. the all has two running surfaces 6i, 7th at the ends by an enlarged central area8 of each other are separated. This area leads to the public openings 9 of the lantern. Through these openings can be used in the manufacture of rolls Grc ^ ifen slider of the form. the extended Fill in space 8. The digits are on the Numeral wreath i printed on and the print through a radially projecting Sclltitzraii <I io ge protects. Such a] tariff has the following advantages. By the spaced-apart ski run fläcbell egg, 7 the trolls get a good lead. Their friction is also reduced. About between The running surface and the axle can become entangled with dust migrate inwards or outwards.
