Abstract

The oscillation system has a a circular oscillator (14) mounted coaxially on a rotary oscillator shaft (1), which is enclosed by a spiral spring (5), secured to the oscillator shaft at its inner end and to a fixed point at its outer end. The oscillator is provided by a ceramics disc, e.g. a ceramic glass disc with a central bore for insertion of the oscillator shaft to which the disc is attached via an adhesive, the oscillator shaft coupled to an anchor escapement mechanism.

Description

Die Erfindung bezieht sich auf eine Unruh für eine me­ chanische Uhr, wobei die Unruh kreisformartige Kontur besitzt und koaxial auf einer drehbar gelagerten Unruh­ welle fest angeordnet ist.The invention relates to a balance for a me Chanian clock, the balance has a circular contour owns and coaxially on a rotatable balance shaft is fixed.

Üblicherweise ist die Unruh für eine Uhr aus einem Me­ tall, insbesondere einem ferromagnetischen Metall aus­ gebildet. Bei Temperaturänderung führt dies durch Wär­ meausdehnung oder Kälteschrumpfung zu einer Veränderung des Durchmessers der Unruh. Dadurch kommt es tempera­ turabhängig zu einem schnelleren oder langsameren Schwingen der Unruh und somit zu Gangungenauigkeiten der Uhr.Usually, the balance for a watch is from a me tall, in particular a ferromagnetic metal educated. If the temperature changes, this leads to heat expansion or cold shrinkage to a change of the diameter of the balance wheel. This way it comes tempera depending on the door to a faster or slower one Swinging of the balance wheel and thus to inaccuracies the clock.

Aufgabe der Erfindung ist daher eine Unruh der eingangs genannten Art zu schaffen, die eine erhöhte Ganggenau­ igkeit der Uhr ermöglicht.The object of the invention is therefore a balance in the beginning mentioned type to create an increased accuracy clock.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Unruh aus Keramik besteht. Da sich bei Temperatur­ änderungen eine derartige Unruh in ihren Abmessungen weitgehend nicht verändert, kommt es nicht zu einer Gangänderung. This object is achieved in that the balance wheel is made of ceramic. Because at temperature Changes such a balance in its dimensions largely unchanged, there is no Change of gear.  

Darüber hinaus bleibt die Unruh auch durch magnetische oder elektromagnetische Felder in der Nähe der Uhr un­ beeinflußt, was ebenfalls zur Bewahrung der Ganggenau­ igkeit der Uhr beiträgt.In addition, the balance remains due to magnetic or electromagnetic fields near the watch affects what also to preserve the accuracy accuracy of the watch.

Besteht die Unruh aus Glaskeramik, so ist sie durch­ sichtig und somit nicht sehbehindernd für das Uhrwerk bei z. B. einer Uhr mit einem Glasboden oder bei der Montage der Uhr.If the balance wheel is made of glass ceramic, it is worn out visible and therefore not obstructing the watch movement at z. B. a clock with a glass bottom or at Assembly of the clock.

Ist die Unruh scheibenartig ausgebildet, so kann diese leicht und mit hoher Präzision hergestellt werden.If the balance is disc-shaped, it can can be manufactured easily and with high precision.

Die Unruh kann einteilig ausgebildet sein.The balance wheel can be made in one piece.

Ein Ausführungsbeispiel der Erfindung ist in der Zeich­ nung dargestellt und wird im folgenden näher beschrie­ ben. Die einzige Figur der Zeichnung zeigt eine per­ spektivische Ansicht eines Schwingsystems.An embodiment of the invention is in the drawing shown and will be described in more detail below ben. The only figure in the drawing shows a per perspective view of a vibration system.

Das in der Figur dargestellte Schwingsystem weist eine scheibenartige Unruh auf, die aus einer kreisförmigen Scheibe 2 aus Keramik sowie einer Unruhwelle 1 besteht. Die Scheibe 2 weist eine zentrische Bohrung auf, durch die die Unruhwelle 1 hindurchragt und mittels einer Klebung drehfest mit der Scheibe 2 verbunden ist. The vibration system shown in the figure has a disc-like balance, which consists of a circular disc 2 made of ceramic and a balance shaft 1 . The disc 2 has a central bore through which the balance shaft 1 protrudes and is connected to the disc 2 in a rotationally fixed manner by means of an adhesive.

Die Unruhwelle 1 ist von einer Spiralfeder 5 umschlos­ sen, die mit ihrem inneren Ende an der Unruhwelle 1 und mit ihrem äußeren Ende an einem drehfest einstellbaren Bauteil befestigt ist.The balance shaft 1 is enclosed by a spiral spring 5 , which is attached with its inner end to the balance shaft 1 and with its outer end to a non-rotatable component.

Die Unruhwelle 1 ist über eine Ankergabel 6 mit dem An­ ker 7 einer Ankerhemmung in Wirkverbindung und schwin­ gend antreibbar.The balance shaft 1 is driven by an anchor fork 6 with the ker 7 of an anchor escapement in operative connection and vibrating.

Die Unruhwelle 1 ist in einem unteren und einem oberen Lager 8 drehbar gelagert, wobei das obere Lager 8 an einem feststehenden Träger 9 angeordnet ist.The balance shaft 1 is rotatably supported in a lower and an upper bearing 8 , the upper bearing 8 being arranged on a fixed support 9 .
