Description
Man hat bisher beim Ankerrad von Ankerhemmungen dem Verhältnis der Zähnezahl zur Zahl der Arme oder Speichen keine Beachtung geschenkt. Die Zahl der Arme oder Speichen wurde von den Fachleuten immer als eine Frage zweiten Ranges behandelt. Man hat sich nie überlegt, ob vielleicht nicht doch die von sich werfenden Rädern herrührenden Gangfehler ihre Ursache in einem ungünstigen Verhältnis der Zähnezahl zur Speichenzahl haben könnten.So far, the escape wheel of anchor escapements has the ratio of No attention is paid to the number of teeth to the number of arms or spokes. The number of Arms or spokes has always been considered a secondary question by experts treated. One has never considered whether maybe not the throwing oneself off Gear errors caused by the wheels are caused by an unfavorable ratio of the Number of teeth to number of spokes could have.
Es wurde nun gefunden, daß die Möglichkeit von Gangfehlern aller Art und der Ausschuß unter den fertiggestellten Ankerrädern auf ein Mindestmaß reduziert werden, wenn die Zähnezahl ein ganzes Vielfaches der Arm- oder Speichenzahl ist, d. h. wenn die Zähne in ganzen und gleich großen Zahlen zwischen den Speichen verteilt sind.It has now been found that the possibility of gait errors of all kinds and the scrap under the completed escape wheels reduced to a minimum if the number of teeth is a whole multiple of the number of arms or spokes, d. H. when the teeth are distributed in whole and equal numbers between the spokes are.
Gegenstand vorliegender Erfindung ist daher ein Ankerrad, das dadurch gekennzeichnet ist, daß seine Zähnezahl ein ganzes Vielfaches seiner Speichenzahl ist, wobei die Zähne gleichmäßig zwischen den Speichen verteilt sind. Da die Zähnezahl in den meisten Uhren durch die Zahl der Unruhschwingungen pro Minute gegeben und ein Vielfaches von fünf ist, so gibt man dem erfindungsgemäßen Ankerrad mit Vorzug fünf Speichen.The present invention is therefore an escape wheel, which thereby is characterized by the fact that its number of teeth is a whole multiple of its number of spokes with the teeth evenly distributed between the spokes. As the number of teeth in most clocks given by the number of balance oscillations per minute and is a multiple of five, the escape wheel according to the invention is given preference five spokes.
Die Zeichnung zeigt eine beispielsweise Ausführungsform des erfindungsgemäßen Ankerrades. Die einzige Abbildung zeigt das Rad im Grundriß.The drawing shows an example embodiment of the invention Escape wheel. The only illustration shows the wheel in plan.
Das dargestellte Rad hat fünfzehn Zähne i und fünf Speichen oder Arme 2, so daß sich zwischen je zwei Speichen 2 drei Zähne i befinden. Ein solches h ad ist vollkommen ausbalanciert, und die bei seiner Herstellung auftretenden Spannungen verteilen sich gleichmäßig auf alle Speichen, so daß Fehler durch Unrundwerden auf ein Kleinstmaß herabgesetzt sind.The illustrated wheel has fifteen teeth and five spokes or arms 2, so that there are two three teeth i between every two spokes. Such a h ad is perfectly balanced, and the stresses involved in its manufacture are evenly distributed over all spokes, so that errors due to out-of-roundness arise are reduced to a minimum.
Die Zahl der Zähne könnte größer als fünfzehn sein, wird aber immer ein ganzes Vielfaches der Speichenzahl betragen.The number of teeth could be greater than fifteen, but always will be a whole multiple of the number of spokes.
