腕表和所有机器一样,要它能够运行,首先要有动力。动力可来自大自然,最简单的莫如人手推动,但这又引伸另一个更重要问题,人不可能24小时不停工作,于是又要找方法把这些动力储存起来,让它在人手停止再推动时,仍能不停地自动发放。这就是机械钟表上链的原理:我们替钟表上链时,把盒内有弹性的发条暂时强加收紧,当我们停止再上链时,发条的惯性令它要回复原来松开的状态,于是便产生动力。我们又可以通过机械齿轮的制动设计,令发条的动力慢慢发放,不会像爆气球一样一下子把动力完全释放。
Watches, like all other machines, must be motivated to run on. Motivation can come from nature. The simplest mode of action is manpower promotion. But this, in turn, leads to another more important issue. It is impossible for people to work 24 hours a day so they have to find ways to store these motives and stop it from moving forward When, can still be automatically released. This is the principle of mechanical watches on the chain: When we clock on the watch, the box has a flexible spring temporarily imposed to tighten, when we stop re-winding, winding inertia makes it to return to the original state of release , So it produces power. We can again through the mechanical gear brake design, so that the power of the clock issue slowly, will not be like a burst of balloons, the power completely released.
