Description
Verfahren zur Erzielung einer konzentfis@4eiikerführung bei Topf- o. dgl. Magnete(' Bei der Führung, z. B. in Topfmagneten, muß bekanntlich eine ganz, genaue konzentrische Abstandshaltung des Ankers gewährleistet sein, um auch bei den gegebenen Minimalabständen in der Größenordnung von i bis 5 Hundertstel Millimeter eine Polberührung auszuschließen.Procedure for achieving a concise guidance in pot or similar magnets ('When guiding, e.g. in pot magnets, it is well known that a exact concentric spacing of the armature must also be ensured the given minimum distances in the order of 1 to 5 hundredths of a millimeter exclude a pole contact.
Durch aufgezogene Führungsringe aus nicht magnetisierbarem Material ist- der gewünschte Erfolg deshalb nicht zu erzielen, als schon die üblichen ungleichen Wandstärken oder Stauchungen beim Aufziehen dünner Ringe die erforderliche-- genau konzentrische Lagerung unmöglich machen.With pulled-on guide rings made of non-magnetizable material the desired success is therefore not to be achieved, as already the usual unequal Wall thicknesses or upsets when pulling on thin rings the required - exactly make concentric storage impossible.
Die Erfindung zeigt einen neuen Weg, die erforderliche konzentrische Übereinstimmung zwischen Ringführungs- und Magnetfläche zu erzielen und somit auch bei geringsten Polabständen Berührungen auszuschalten.The invention shows a new way of achieving the required concentric To achieve correspondence between the ring guide and magnetic surface and thus also to switch off contacts at the smallest pole spacing.
Verfahrensgemäß erfolgt ein gemeinsames Abdrehen der entsprechend größer gehaltenen Führungsring- und Ankermantelflächen in einem Zuge auf den gegebenen Halsdurchmesser und dann bei gleicher Einspannung ein Abdrehen der Ankermantelfläche allein um den gewünschten Minimalabstand.According to the method, a joint turning off takes place accordingly larger guide ring and armature jacket surfaces in one go on the given Neck diameter and then with the same clamping a turning of the anchor surface area just about the desired minimum distance.
In der Zeichnung sind die einzelnen Verfahrensstufen - beispielsweise veranschaulicht. Es zeigen: Abb. i den Anker mit den aufgezogenen Führungsringen vor der- Bearbeitung, Abb. 2 das Werkstück nach Abb. i nach dem gemeinsamen Abdrehen und Abb. 3 das Werkstück nach weiterem Abdrehen des Ankers allein.In the drawing are the individual process stages - for example illustrated. They show: Fig. I the anchor with the guide rings attached Before machining, Fig. 2, the workpiece according to Fig. i after the joint turning and Fig. 3 the workpiece alone after further twisting off the anchor.
In Abb. i ist das unbearbeitete Werkstück gezeigt und dabei :ersichtlich gemacht, daß der Radius a der Innenfläche des Halses i sowohl kleiner als der Radius b der Mantelflächen der Führungsringe-- als auch kleiner als der Radius c der Mantelflächedes Ankers 3 ist.The unprocessed workpiece is shown in Fig. I and can be seen made that the radius a of the inner surface of the neck i is both smaller than the radius b of the outer surfaces of the guide rings - as well as smaller than the radius c of the outer surface of the Anchor 3 is.
Bei dem Werkstück nach Abb.2*sind die Radien a, b und c gleich. Anschließend erfolgt nun bei der gleichen Einspannung das weitere Abdrehen oder Abschleifen nur des Zylindermantels des Ankers 3 gemäß Abb. 3, wodurch der gewünschte konzentrische Minimalabstand x von den Führungsflächen zuverlässig erzielt wird.For the workpiece according to Fig. 2 *, the radii a, b and c are the same. Afterward only further turning or grinding takes place with the same clamping of the cylinder jacket of the armature 3 according to Fig. 3, whereby the desired concentric Minimum distance x from the guide surfaces is reliably achieved.
