Mechanical watch working principle analysis

Mechanical watch working principle analysis

The working principle of mechanical watches is the use of the balance of the balance wheel movement (similar to the pendulum) to determine the "1 second" this time interval.

Balance wheel

The use of elastic deformation of the spring to provide travel time power to supplement the balance wheel movement friction loss. The use of sophisticated gear system to determine the time-sharing second hand speed relationship. For self-winding mechanical watches, there is a set of mechanical structure, the use of pendulum motor energy to winding the winding.

The simplest and most basic watch structure is divided into five systems. Respectively, the original system (clockwork storage energy), the transmission system (gear), escapement speed control system (balance spring, balance wheel speed needle), the last needle dial system Pointer display system (hour hand, minute hand, second hand)

Manual mechanical movement

Manual mechanical movement is the principle of travel time, winding system through the winding storage of energy, and then the gear transmission of energy to the escapement speed control system. The key point is coming! There is a theorem that the hairspring has the same meaning that the same hairspring, when pushed by force, will have the same period of time required to expand and contract these two processes. Such a cycle time is theoretically fixed, so the watch's display time is by recording this fixed period. Speed ​​control system to accept the energy of the cycle, the cyclical operation, and then react to the train wheel, so that the smooth rotation of the cycle in accordance with the cycle. And then through the special design of the gear ratio, you can specifically display by the pointer system is what time. How many minutes. How many seconds.
