Description

Zeigerantriebsvorrichtung Es sind bereits Zeigerantriebsvorrichtungen bekannt, bei denen der Zeiger vom Meßwerk durch eine magnetische (elektromagnetische) Kupplung mitgenommen wird.Pointer Drive Devices There are already pointer drive devices known, in which the pointer from the measuring mechanism by a magnetic (electromagnetic) Coupling is taken.

Gegenstand der Erfindung ist eine weitere Ausbildung derartiger Kupplungen, und ihr wesentliches Kennzeichen besteht darin, daß mindestens ein Kupplungsglied ('Magnet oder Anker) nach' einer Kurve (z. B. nach einer Schrauben- oder Spirallinie) gekrümmt ist, deren Gestalt den zwischen Meßwerk und Anzeigeglied erwünschten Übersetzungsverhältnissen entspricht.The subject of the invention is a further design of such couplings, and its main characteristic is that at least one coupling member ('Magnet or armature) after' a curve (e.g. after a screw or spiral line) is curved, the shape of which corresponds to the transmission ratios desired between the measuring mechanism and the display element is equivalent to.

Dadurch ist einerseits die Möglichkeit gegeben. das Übersetzungsverhältnis durch bestimmte Formgebung dieses kurvenförmigen Teiles nach einem bestimmten, den Erfordernissen des lleß,.v erkes entsprechenden Gesetz veränderlich zu gestalten, z. B. durch Wahl von Schraubenlinien oder Spirallinien ganz bestimmter Form.On the one hand, this gives the possibility. the gear ratio by a certain shape of this curved part after a certain, the The requirements of the law in accordance with the law, z. B. by choosing helical lines or spiral lines of a very specific shape.

Ferner kann man durch Austausch des kurvenförmig, z. B. nach einer flachgängigen Schraubenlinie gekrümmten Teiles gegen einen anders, z. B. nach einer steilgängigen Schraubenlinie gekrümmten Teil die Größenordnung des Übersetzungsverhältnisses ändern, d. h. die Vorrichtung für einen anderen lMeßbereich verwendbar machen.Furthermore, by replacing the curved, z. B. after a flat helical curved part against a different, z. B. after a steep helix curved part the order of magnitude of the gear ratio change, d. H. make the device usable for a different measuring range.

In der Zeichnung ist der Erfindungsgegenstand in mehreren beispielsweisen Ausführungsformen schematisch veranschaulicht.The subject matter of the invention is shown in several examples in the drawing Embodiments illustrated schematically.

Abb. i zeigt ein Triebwerk, bei dem der Magnet i mit seinen Polen parallel zur Achse 2 des schraubenförmigen verwundenen Ankers 3 verschoben wird. Auf der Achse 2 sitzt auch der Zeiger .1. Abb. 2 stellt einen Schnitt nach a-b der Abb. i dar. Bei der Ausführungsform nach AM. 3 ist der 'Magnet i um eine Achse 5 schwingbar, o daß der Polschuh 6 sich in einer Ebene parallel zur Achse 2 bewegen kann. Abb.4 zeigt die Ausbildung des Polendes in Form einer archimedischen Spirale Gemäß Abb. 5 ist statt des 'Magneten i ein parallel zur Achse 2 verschiebbares weiches Eisenstück i' verwendet, welches durch das Feld des feststehenden Magneten 8 magnetisiert wird und auf den schraubengangförmig gestalteten Anker 3 wirkt.Fig. I shows an engine in which the magnet i is displaced with its poles parallel to the axis 2 of the helical, twisted armature 3. The pointer .1 is also located on axis 2. Fig. 2 shows a section from fig. I. In the embodiment according to M. A 3 is the 'Magnet i swingable about an axis 5, o that the pole piece 6 can move in a plane parallel to the axis 2. Fig. 4 shows the formation of the pole end in the form of an Archimedean spiral Armature 3 acts.
