The vibration mechanism is mainly composed of a balance wheel, pendulum shaft, hairspring, fast and slow needles, etc. The balance wheel will deviate from its equilibrium position and start to swing when subjected to external forces. At this time, the balance spring is twisted to generate a restoring torque. This is the principle of repeated cycles of mechanical wall clock operation.
The power mechanism is a mechanism that stores and transmits working energy, and generally includes a barrel wheel, a barrel cover, a barrel shaft, a barrel, and a barrel hook. The mainspring is a spiral or S-shaped spring, which can be tightened through the winding needle system, and the elastic energy of the tightened mainspring can drive the transmission mechanism.
The transmission mechanism transfers energy to a set of gears of the escapement speed regulation mechanism, which is generally composed of two wheels (center wheel), three wheels (passing wheels), four wheels (second wheel), and escapement gear shafts.
The escapement speed regulation mechanism is composed of two parts, the escapement mechanism, and the vibration mechanism. It relies on the periodic vibration of the vibration system to keep the escapement mechanism is precise and regular intermittent movement, thereby achieving speed regulation. The forklift escapement is the most widely used escapement. The escapement mechanism can transfer energy to the vibration system.
