恒定动力 恒定动力擒纵系统

不论是完全上链还是近乎松链,机械表的恒定动力擒纵系统也可为擒纵轮提供均匀动力。这个多用途的装置更可驱动其他瞬跳显示功能。  

恒定动力:专利恒定动力擒纵系统 – 朗格

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.

如马拉松选手般坚持不懈

 

配备两个强大主发条的双发条盒,为RICHARD LANGE PERPETUAL CALENDAR “Terraluna”提供14天动力储存;LANGE 31的动力储存更长达31天。就如马拉松选手,恒定动力擒纵系统消耗相当多的能量,这些能量还须逐少传递。如完全上链,由这个高动能主发条盒直接传递至擒纵系统的扭力将会过大。如接近未上链的状态,扭力则会减弱,因而降低腕表的精准度。为在整个动力储存期间保持腕表速率稳定,两款腕表的双发条盒和擒纵系统之间特别装配了专利恒定动力擒纵系统。  

 

这有效控制双发条盒每十秒钟提供少量动力。此动力让恒动游丝维持60度角。这恰好对应恒动游丝在下十秒钟传递至擒纵轮、杠杆和摆轮游丝的动力。由于恒动游丝可一直准确传送相同动能,因此腕表每天均由相同扭力所驱动。这为腕表带来恒定振幅,以达到高水平的精准度。恒定动力擒纵系统的恒动游丝和摆轮游丝均由表厂自行研制,与机芯精妙匹配。

如虎添翼

 

ZEITWERK表款配备的恒定动力擒纵系统,不仅为擒纵轮提供稳定动力,还产生切换动力,推进跳字显示。恒定动力擒纵系统犹如伺机猛扑的猛兽,必须迸发出强大力量。系统每60秒精准完成重新拉紧的循环。主发条盒的全部扭力会在一瞬间释放,然后再次拉紧。这股“爆发力”亦即用于切换数字盘。  

如蜂鸟般轻快

 

RICHARD LANGE JUMPING SECONDS的恒定动力擒纵系统和跳秒装置用于分隔紧密相连的轮系。就像高速拍动翅膀才能在半空中停留的蜂鸟,恒定动力擒纵系统必须在一秒间完成多个快速切换步骤。主发条盒每秒短暂释放一次。在过程中,主发条盒将秒针向前推动一秒,并逐渐拉紧恒定动力擒纵系统的游丝。恒定动力使腕表自始至终精准运行。
