Claims (15)

  1. Drehachse (1) einer Unruh, eines Ankers oder eines Hemmungsritzels für ein Uhrwerk, die an mindestens einem ihrer Enden mindestens einen Drehzapfen (3) aus Metall aufweist, dadurch gekennzeichnet, dass das Metall eine nichtmagnetische Aluminiumlegierung ist, um seine Empfindlichkeit gegenüber Magnetfeldern zu begrenzen, und dadurch, dass entsprechend einer vorgegebenen Tiefe zumindest die Außenfläche (5) des Drehzapfens (3) im Verhältnis zur Achsenmitte in der Tiefe gehärtet ist.
  2. Drehachse (1) nach Anspruch 1, dadurch gekennzeichnet, dass die vorgegebene Tiefe zwischen 5 % und 40 % des Gesamtdurchmessers (d) des Drehpunkts (3) beträgt.
  3. Drehachse (1) nach einem der Ansprüche 1 oder 2, dadurch gekennzeichnet, dass die in der Tiefe gehärtete Außenfläche (5) diffundierte Atome mindestens eines chemischen Elements aufweist.
  4. Drehachse (1) nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass die in der Tiefe gehärtete Außenfläche (5) eine Härte von mehr als 600 HV aufweist.
  5. Drehachse (1) nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass die nichtmagnetische Aluminiumlegierung ausgewählt ist aus der Gruppe bestehend aus einer Aluminium-Kupfer-Blei-Legierung, einer Aluminium-Silizium-Magnesium-Mangan-Legierung und einer Aluminium-Zink-Magnesium-Kupfer-Legierung.
  6. Drehachse (1) nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass die Außenfläche (5) des Drehzapfens (3) keine direkt auf der Außenfläche aufgebrachte Härtungsschicht aufweist.
  7. Drehachse (1) nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass zumindest die Außenfläche (5) des Drehzapfens (3) gerollt ist.
  8. Drehachse (1) nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass sie zwei Drehzapfen umfasst.
  9. Uhrwerk für ein Zeitmessgerät, dadurch gekennzeichnet, dass es eine Drehachse (1) nach einem der vorhergehenden Ansprüche umfasst.
  10. Uhrwerk für ein Zeitmessgerät, dadurch gekennzeichnet, dass es eine Unruhwelle (1), eine Ankerstange und/oder ein Hemmungsritzel mit einer Achse nach einem der Ansprüche 1 bis 8 umfasst.

    a) Bilden einer Drehachse (1), die an mindestens einer ihrer Enden mindestens einen Drehzapfen (3) aus Metall aufweist, wobei das Metall eine nichtmagnetische Aluminiumlegierung ist, um seine Empfindlichkeit gegenüber Magnetfeldern zu begrenzen;
    b) Diffundieren von Atomen durch einen lonenimplantationsprozess entsprechend einer vorbestimmten Tiefe zumindest in die Außenfläche (5) des Drehzapfens (3), um die Drehachse (1) an den Hauptspannungszonen in der Tiefe zu härten und dabei eine hohe Zähigkeit beizubehalten.
  12. Verfahren nach Anspruch 11, dadurch gekennzeichnet, dass die vorgegebene Tiefe zwischen 5 % und 40 % des Gesamtdurchmessers (d) des Drehzapfens (3) beträgt.
  13. Verfahren nach einem der Ansprüche 11 oder 12, dadurch gekennzeichnet, dass der Schritt des Diffundierens das Diffundieren von Atomen mindestens eines chemischen Elements umfasst.
