The coil spring (spring, an elastic element) stores the energy expressed in the form of moments, and the multi-stage gears of the fixed transmission ratio respectively display different time units.
Using a coil spring with a precisely fixed vibration period (hairspring, an elastic element, made of a constant-elastic alloy) and a non-linear oscillating mechanical clutch - the brake, professionally known as the escapement, at a precise angular velocity, the coil spring (spring, an elastic element) stores the energy expressed in the form of moments.
The rotational angular velocities of the different hands are different and are each constant.
A few decades ago, the national unified design mechanical clock core produced in China was N1 type. I used it to make a weekly cycle timer, except Sunday, other days, every day from 6 to 7 o'clock, automatic pre- The thermal circuit reduces the labor of the staff.
Traditionally, it is 6 to 7 o'clock every morning. The operator starts the electric furnace and goes home. At 8 o'clock in the morning, the temperature of the mechanical timer furnace reaches the rated value before the formal work begins.
