Interpretation Of Quartz Clock Movement And Mechanical Clock Principle
Oct 13, 2018

The core of quartz crystal sensor of quartz clock movement is sensor element -- piezoelectric quartz wafer. Its working principle is piezoelectric effect. On the contrary, when a voltage is applied to a certain direction of quartz, it will deform in a particular direction. This phenomenon is called inverse piezoelectric effect. If the alternating electric field is applied to the quartz crystal, the crystal lattice will produce mechanical vibration. When the frequency of the external electric field is consistent with the natural oscillation frequency of the crystal, the resonance of the crystal will appear. Because quartz crystals produce very small electric fields under pressure, they can be deformed with only a very weak external electric field, which makes it easy for piezoelectric quartz crystals to generate resonance under the excitation of an external alternating electric field. Due to its low energy loss and extremely stable vibration frequency, quartz has been used as a frequency reference element related to digital circuits since the 1940s because of its excellent mechanical, electrical and chemical stability

A winder is a component that powers a clock. Circle around the box. Tighten the spring using the milling slots on the bar shaft. The square groove of the bar shaft is driven by the upper bar mechanism. The clock is capable of walking between 36 and 50 hours without a rewinding. At present, the use of alloy material makes the spring almost unbreakable, as the spring often breaks under obvious stress. The spring stores a certain amount of energy, which is distributed uniformly and in small quantities to the oscillator. For this purpose, the energy provided passes through the wheel train group, which reduces the transmission force in the same proportion while increasing the number of turns. The wheel column group includes 4 wheels and 4 gears, and the latter 3 wheels are riveted on the first 3 gears. On the schematic diagram, the diagonal line represents the mesh between the moving parts, while the horizontal line indicates that the moving parts are riveted on the same axis. The first wheel is a circular milling tooth of the box wheel. The last wheel is the escapement gear, which is riveted by the escapement wheel. The escapement wheel belongs to the distribution mechanism and counter. The box rotation takes about 6 hours, during which time the escapement gear and escapement rotation take about 3,600 turns. This number represents the ratio of rotation frequency between the first and last wheel. The ratio is always within this numerical range. Try to keep the gears and dividing wheels in the center of the watch and make one turn per hour.

First, add electricity to the crystal sheet in the quartz clock, and the crystal will vibrate correctly at 32,768 hz. The signal frequency must then be reduced to 1Hz (a change in current in a second). Increase the signal amplitude (due to the weak current generated by the vibration), follow some signal current to start the rotor gear, the second hand on the watch will start, after the minute hand, the clockwise beat is related to the mechanical structure of the principle, such as: the second hand beat 60 times, the minute hand will jump.

All quartz watches have a battery. It provides energy for an integrated circuit and a quartz resonator that vibrates 327,678 times per second. There's something faster than that. The integrated circuit is the "brain" of the table. It controls the vibration of the quartz resonator and ACTS as a frequency divider. 32,768 vibrations were split in half 15 times to produce one pulse per second. With a second of the "raw material" of kushiro's time, it drives the display.
