Description
Bestandteil für Uhren, welcher reibende Flächen aufweist Uhrenteile, welche Flächen aufweisen, die einer Reibungsbeanspruchung unterworfen sind, werden bis heute meist aus Messing, teilweise auch aus Stahl herge stellt. Solche Teile sind z. B. die Teile der Hemmung (Anker und Ankerrad), die Teile des Mechanismus, welche bei Kalenderuhren die Datumsanzeige betäti gen, das Federhaus bei Selbstaufzuguhren u. a.
Bei dieser Ausführungsform treten immer wieder dadurch Schwierigkeiten auf, dass sich die Reibung zwischen den aufeinandergleitenden Flächen infolge mangelhaften Gleiteigenschaften vergrössert, oder dass die reibenden Flächen anfressen, was zu Störungen im Gang der Uhr führt.
Im Schweizer Patent Nr. 337455 wird darauf hin gewiesen, dass man die Gleiteigenschaften zwischen Federhaus von Selbstaufzuguhren und der Aufzug feder, welche ja bekanntlich eine Rutschkupplung bilden, verbessern kann, wenn man das Federhaus aus anodisch oxydiertem Aluminium herstellt. Die dadurch erzeugte Oberflächenschicht bewirkt eine Verbesserung der Reibungseigenschaften, wobei weit gehend das Anfressen der Oberfläche vermieden wird.
Durch eingehende Versuche ist nun festgestellt worden, dass man nicht nur das Trägheitsmoment der Teile einer Ankerhemmung, also des Ankerrades und des Ankers herabsetzen kann, sondern auch die mechanischen und physikalischen Eigenschaften anderer Uhrenbestandteile, welche reibende Flächen aufweisen, wie z. B. Hebel und Klinken im Datums mechanismus von Kalenderuhren, verbessern kann, wenn man diese und ähnliche Uhrenbestandteile aus anodisch oxydierbarem Aluminium oder einer anodisch oxydierbaren Aluminiumlegierung herstellt.
Der erfindungsgemässe Uhrbestandteil ist nun da durch gekennzeichnet, dass er aus Aluminium oder einer Aluminiumlegierung besteht, deren Oberfläche anodisch oxydiert ist. Unter der Bezeichnung anodisch oxydiert ist jenes Verfahren zu verstehen, welches üblicherweise auch als Eloxalverfahren be zeichnet wird.
Als Aluminiumlegierungen, welche für Uhrbe standteile gemäss der Erfindung Verwendung finden können, kommen aushärtbare Legierungen in Frage, wie z. B. solche mit nachfolgender Zusammen setzung:
EMI0001.0026
<U>Legierung <SEP> I <SEP> Legierun</U>g <SEP> <U>II</U> <SEP> Legierung <SEP> III

<tb> Si.

<tb> A1 <SEP> Rest <SEP> A1 <SEP> Rest <SEP> Al <SEP> Rest Zur Erzielung einer erhöhten Festigkeit werden diese Legierungen zweckmässigerweise einer geeig neten Wärmebehandlung unterworfen. So wird man z.
B. die Festigkeit der Legierung I durch Ab schrecken aus einer Temperatur von 530 bis 550 C und Auslagern bei 155 bis 160 C während 4 Stun den, jene der Legierung 1I durch Abschrecken aus einer Temperatur von 505-515 C und Auslagern bei Zimmertemperatur während 100 Stunden und jene von Legierung III durch Glühen bei einer Tem peratur zwischen 400 und 440 C während etwa 5 Stunden und anschliessendes Glühen bei einer Tem peratur zwischen 250 und 340 C während 4 bis 8 Stunden erhöhen.
Als weiterer Vorteil kommt für die Ankerteile hinzu, dass diese bei Verwendung von Aluminium- legierungen an Stelle von Schwermetallegierungen leichter werden, ein geringes Trägheitsmoment be sitzen und deshalb weniger Energie zu ihrer Bewe gung benötigen. Ferner sind infolge des geringeren Gewichtes der Lagerdruck und die Lagerreibung geringer.
Ein weiterer Vorteil der erfindungsgemässen Uhr bestandteile besteht darin, dass sie - aus Alumi niumlegierungen hergestellt - weitgehend korro sionsfest und unmagnetisch sind und sich überdies gut bearbeiten lassen.
Component for watches that has rubbing surfaces Watch parts that have surfaces that are subjected to frictional stress are mostly made of brass, sometimes also of steel, to this day. Such parts are e.g. B. the parts of the escapement (anchor and escape wheel), the parts of the mechanism which actuate the date in calendar watches, the barrel for self-winding watches and. a.
In this embodiment, difficulties arise again and again in that the friction between the surfaces sliding on one another increases as a result of poor sliding properties, or that the friction surfaces erode, which leads to malfunctions in the running of the watch.
In Swiss patent no. 337455 it is pointed out that the sliding properties between the barrel of self-winding watches and the winding spring, which are known to form a slip clutch, can be improved if the barrel is made of anodically oxidized aluminum. The surface layer thus produced improves the friction properties, largely avoiding pitting of the surface.
Through detailed tests it has now been found that you can not only reduce the moment of inertia of the parts of an anchor escapement, so the escape wheel and the anchor, but also the mechanical and physical properties of other watch components that have rubbing surfaces, such. B. levers and pawls in the date mechanism of calendar watches, can improve if you make these and similar watch components from anodically oxidizable aluminum or an anodically oxidizable aluminum alloy.
The clock component according to the invention is characterized in that it consists of aluminum or an aluminum alloy, the surface of which is anodically oxidized. The term anodically oxidized is to be understood as the process which is usually also referred to as an anodizing process.
As aluminum alloys, which can be used for Uhrbe components according to the invention, hardenable alloys come into question, such. B. those with the following composition:
EMI0001.0026
<U> alloy <SEP> I <SEP> alloy </U> g <SEP> <U> II </U> <SEP> alloy <SEP> III
<tb> Cu <SEP> - <SEP> Cu <SEP> <B> 3.5-5 </B> <SEP> Cu <SEP> <B> 1-2.5 </B>
<tb> Si.
<SEP> 0.5-1.5 <SEP> Si <SEP> 0-1 <SEP> Si <SEP> Mn <SEP> 0.2-1 <SEP> Mn <SEP> 0.2-1.5 <SEP> Mn <SEP> 0.2-1

<tb> Cr <SEP> - <SEP> Cr <SEP> - <SEP> Cr <SEP> 0.1-1
<tb> Zn <SEP> - <SEP> Zn <SEP> - <SEP> Zn <SEP> 5.5-7
<tb> A1 <SEP> remainder <SEP> A1 <SEP> remainder <SEP> Al <SEP> remainder In order to achieve increased strength, these alloys are expediently subjected to a suitable heat treatment. So you will z.
B. the strength of alloy I by quenching from a temperature of 530 to 550 C and aging at 155 to 160 C for 4 hours, that of alloy 1I by quenching from a temperature of 505-515 C and aging at room temperature for 100 Hours and those of alloy III by annealing at a temperature between 400 and 440 C for about 5 hours and subsequent annealing at a temperature between 250 and 340 C for 4 to 8 hours.
Another advantage for the anchor parts is that they become lighter when using aluminum alloys instead of heavy metal alloys, have a low moment of inertia and therefore require less energy to move them. Furthermore, the bearing pressure and bearing friction are lower due to the lower weight.
Another advantage of the clock components according to the invention is that they - made of aluminum alloys - are largely corrosion-resistant and non-magnetic and, moreover, can be processed easily.
