Description
Uhrenunruh und Verwahren zu ihrem Auswuchten Die vorliegende Erfindung betrifft eine Uhrenunruh, insbesondere für elektrische Uhren, die nit mindestens einem Element von schwer nachpriifbarer Dichte und mindestens einem Gegengewieht versehen ist. Watch balance and storage for balancing it The present invention relates to a clock balance, in particular for electrical clocks that do not have at least an element with a density that is difficult to verify and at least one counterweight is provided.
Die Erfindung betrifft außerdem ein Verfahren zum Auswuchten dieser Unruh.The invention also relates to a method for balancing these Balance.
Das Auswuchten von Uhrenunruhen, die mit Elementen von schwer nachpriifbarer Dichte wie beispielsweise mit den in elektrisehen Uhren ganz allgemein enthaltenen Magneten versehen sind, stellt Probleme auf Grund der Tatsache, daß diese Magneten mitunter eine mangelhafte Homogenität aufweisen, die derart sein kann, daß die Werkstoffwegnahme, die das Auswuchten bewirken soll, außerhalb des eigentlichen Gegengewichtes zu liegen kommen kann.The balancing of clock balance with elements that are difficult to verify Density such as that contained in electrical clocks in general Magnets are provided poses problems due to the fact that these magnets sometimes show a lack of homogeneity, which can be such that the removal of the material, which should cause the balancing to lie outside the actual counterweight can come.
Der Zweck der Erfindung ist es, diesen Mangel zu beheben.The purpose of the invention is to remedy this deficiency.
Die Unruh nach der Erfindung ist dadurch ausgezeichnet, daß das Element Voll schwer nachprüfbarer Dichte und/oder das Gegengewicht von einem Hlater getragen sind, der auf der Welle der Unruh so angebracht ist, daß er in seiner Winkellage verstellbar ist in der Weise, daß zumindest die Grobauswucktung der Unruh durch eine wechselseitige Verstellung des Elements und des Gegengewichts erfolgen kann.The balance according to the invention is characterized in that the element Fully difficult to verify density and / or the counterweight carried by a halter who are on the wave of The balance wheel is attached in such a way that it is in its The angular position is adjustable in such a way that at least the rough swallowing of the balance wheel take place by a mutual adjustment of the element and the counterweight can.
Das Verfahren zum Ausnmchten der Unruh besteht erfindungsgemäß darin, daß die Grobauswuch tung der Unruh durch eine wechselseitige Verstellung des Elcnents von schwer nachprtifbarer Dichte und des Gegengewichts vorgenommen wird, wahrend die Feinauswuchtung durch Wegnahme von Werkstoff des Gegengewichts erfolgt.The method for balancing the balance according to the invention consists in that the coarse bulging of the balance wheel is caused by a reciprocal adjustment of the element of difficult to verify density and counterweight is made while the fine balancing takes place by removing the material of the counterweight.
Weitere Einzelheiten und Vorteile der erfindung sind nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher beschrieben. r;s zeigen: Fig. 1 eine Draufsicht auf eine Unruh für elektrische Uhren und Fig. 2 einen Schnitt nach der Linie II-II in Fig. 1.Further details and advantages of the invention are referenced below an embodiment shown in the drawing is described in more detail. r; s 1 shows a top view of a balance wheel for electrical clocks and FIG. 2 shows one Section along the line II-II in FIG. 1.
Die dargestellte Unruh besteht aus einer Welle 1, auf die eine Muffe 2 aufgepresst ist, die an einen ihrer Enden bei 3 gefaßt eine Platte 4 in Form eines zwei Dauermagneten 5 tragenden Sektors und einen diinnen radialen Arm 6 trägt, der an seinem Ende mit einen das Gegengewicht bildenden Teil 6a in Forn eines Kreisabscilnitts versehen ist.The balance shown consists of a shaft 1 on which a sleeve 2 is pressed on, which is taken at one of its ends at 3 a plate 4 in the form of a two permanent magnets 5 carrying sector and a thin radial arm 6 carrying the at its end with a counterweight forming part 6a in the form of a circular section is provided.
Auf den beiden Magneten 5 ist ein Plättchen 7 befestigt, das ihrrnmagnetischen Nebenschluß gewährleistet. Eine ebenfalls ein magnetisches Nebenschlußteil bildende untere Platte 8 ist bei 9 am unteren Ende der Muffe 2 gefaßt, die so die Aufgabe eines Distanzstücks llat, -Die Fassung der Platte 4 und des eines 6 bei 3 ist derart, daß sich die Platte und der Arm aul der Muffe 2 bei satter lleibung in ihrer Winkellage verstellen lassen. Auf Grund dieser Anordnung läßt sich die wechselseitige Winkelstellung zwische@ dem Magneten 5 und dem Gegengewicht 6a so einstellen, daß zumindest die Grobanswuchtung der Unruh bewirkt wird.A plate 7 is attached to the two magnets 5, which is their magnetic Shunt guaranteed. One also forming a magnetic shunt lower plate 8 is taken at 9 at the lower end of the sleeve 2, which so the task of a spacer llat, -The version of the plate 4 and that of a 6 at 3 is such, that the plate and the arm aul of the sleeve 2 with full reveal in their angular position can be adjusted. Because of this arrangement can be the mutual Adjust the angular position between @ the magnet 5 and the counterweight 6a so that at least the rough balancing of the balance is effected.
@ötigenfalls erfolgt die Feinanswuchtung durch Wegnahme von Werkstoff des Gegengewichts.If necessary, fine balancing is carried out by removing material of the counterweight.
Auf diese Weise wird die Gefahr beseitigt, daß die Werkstoffwegnahme außerhalb des eigentlichen Gegengewichts zu liegen kommt.In this way, the risk of the material being removed is eliminated comes to lie outside the actual counterweight.
Es sei darauf hingewiesen, daß in der Praxis die Einregulierung erfolgt, indem nur auf das Gegengewicht 6a, um es in seiner Winkel lage zur Achse der Unruh zu verstellen, und nicht auf den Sektor 4 eingewirkt wird, was es notwendig machen würde, die untere Platte 8 um einen entspreehenden Betrag zu verstellen, damit die Magneten 5 in richtiger Lage zur Platte verbleiben.It should be noted that in practice the adjustment takes place, by only on the counterweight 6a to position it in its angular position to the axis of the balance wheel to adjust, and not act on the sector 4, which make it necessary would adjust the lower plate 8 by a corresponding amount so that the Magnets 5 remain in the correct position to the plate.
