恆定動力 恆定動力擒縱系統

不論是完全上鏈還是近乎鬆鏈,機械錶的恆定動力擒縱系統也可為擒縱輪提供均勻動力。這個多用途的裝置更可驅動其他瞬跳顯示功能。  

恆定動力:專利恆定動力擒縱系統

A portrait of Richard Lange appears. Display: A watch in the spirit of Richard Lange. This is followed by exquisite close-up views of a gold pocket-watch, its vibrating balance-wheel and its breathing balance-spring. Display: He turned fine watchmaking into precision watchmaking. The picture of the antique vibrating balance-wheel gives way – almost imperceptibly – to the vibrating balance of the RICHARD LANGE PERPETUAL CALENDER “Terraluna”. We witness the jumping of the patented constant-force escapement. A detailed view of the power-reserve indication follows. Display: 14 days of constant precision. Then a detail of the calendar displays. Display: perpetual calendar. The day-of-the-week indication jumps from Monday to Tuesday. Display: precisely jumping indications. We turn around the side of the case. Display: committed to precision and serving science. In an animation we see a multitude of stars, which deposit themselves on the large celestial disc on the movement side of the RICHARD LANGE “Terraluna”. Suddenly the moon, earth and celestial discs begin to turn in time-lapse, demonstrating the functioning of the orbital moon-phase display. From the rear view, the watch case turns over to the dial side. In a front view of the full watch-face the calendar indications change instantly from Tuesday 25th to Wednesday 26th October.

堅持不懈

 

配備兩個強大主發條的雙發條盒,為RICHARD LANGE PERPETUAL CALENDAR “Terraluna”提供14天動力儲存。LANGE 31的動力儲存更長達31天。就如馬拉松選手般,恆定動力擒縱系統消耗相當多的能量,這些能量還須逐少傳遞。如完全上鏈,由這個高動能主發條盒直接傳遞至擒縱系統的扭力將會過大。如接近未上鏈的狀態,扭力則會減弱,因而降低腕錶的精準度。為整個動力儲存期間保持腕錶速率穩定,兩款腕錶的雙發條盒和擒縱系統之間特別裝配了專利恆定動力擒縱系統。  

 

這有效控制雙發條盒每十秒鐘提供少量動力。此動力讓恆動游絲維持60度角。這恰好對應恆動游絲在往後的十秒鐘傳遞至擒縱輪、槓桿和擺輪游絲的動力。由於恆動游絲可一直準確傳送相同動能,因此腕錶每天均由相同扭力所驅動。這為腕錶帶來恆定振幅,以達致高水平的精準度。恆定動力擒縱系統的恆動游絲和擺輪游絲均由錶廠自行研製,與機芯完美匹配。

如虎添翼

 

ZEITWERK錶款配備的恆定動力擒縱系統,不僅為擒縱輪提供穩定動力,還產生切換動力,推進跳字顯示。恆定動力擒縱系統猶如伺機猛撲的猛獸,必須迸發出強大力量。系統每60秒精準完成重新拉緊的循環。主發條盒的全部扭力會在一瞬間釋放,然後再次拉緊。這股「爆發力」亦即時用於切換數字盤。  

輕快敏捷

 

RICHARD LANGE JUMPING SECONDS的恆定動力擒縱系統和跳秒裝置用於分隔緊密相連的輪系。就像高速拍動翅膀才能在半空中停留的蜂鳥,恆定動力擒縱系統必須在一秒間完成多個快速切換步驟。主發條盒每秒短暫釋放一次。在過程中,主發條盒將秒針向前推動一秒,並逐漸拉緊恆定動力擒縱系統的游絲。恆定動力使腕錶自始至終精準運行。
