The production and production of watches is based on a simple and witty invention. This is the "spring", which can tighten and store energy, and slowly release the energy to push the running device and the pointer in the watch to display The function of time, such a spring device in the watch is called the main spring. The watch construction watch is composed of a watch head and a watch strap (a buckle). The parts of the head include: movement, case, bottom cover, mirror, surface(often said dial), pointer, handle (time adjustment, also called pusher), order (partial requirements).
The working principle of watch, the watch is a precision instrument used to indicate time. The principle of the instrument is to use a constant-cycle, continuous vibration system as the standard. If you know the time (vibration period) required for the vibration system to complete the full vibration of a watch and calculate the number of vibrations, then the time it takes after the vibration is so many times is equal to the vibration period multiplied by the number of vibrations. That is, time = vibration period × number of vibrations
The swing shaft spring mechanical watch adopts a balance spring as a vibration system, and the balance 1 is fixed on the swing shaft 2, and the upper and lower journals of the swing shaft are sleeved in the bearing and can rotate around the bearing. One end of the hairspring member 3 is fixed to the pendulum shaft, and the other end is fixed to the plate. Due to the elastic deformation of the balance spring, the movement of the balance wheel is changed from a rotation to a reciprocating motion. The balance spring system is affected by the frictional force of the bearing, the air resistance and the internal friction of the balance spring during the swing. The amplitude (amplitude) of the swing will gradually decay and finally stop. In order to continue to vibrate without attenuation, it is necessary to periodically replenish the balance spring system, that is to say, there must be an energy device in the watch. The periodic replenishment of energy to the vibrating system is achieved by a special mechanism, an escapement. The escapement is also used to calculate the number of vibrations of the balance spring system. Therefore, the balance spring system and the escapement are the key devices of mechanical watches.
