What is the principle of Automatic watches?

Automatic watch has semi-automatic and automatic, Automatic watch power source is external manual strip, or automatic mechanical watch is through vibration arm swing wrist in the eccentric block rotation table, the final curling stripe elastic potential energy into the kinetic energy of the gear, work, the gear transmission ratio configuration, to a second jump (second needle axis per minute), split needle, timing principle, finally complete the timing function.Let's talk to you about what the principle of a mechanical meter really is.The composition of the mechanical watch

The mechanical watch consists of the movement and the exterior parts.The movement includes transmission train, primary system, upper dial system, escapement system, pointer system. The movement parts are combined by splints with screws; the exterior parts consists of case, dial, pin, and strap, etc.The operation of the clock is to use the leverage principle, like a swing back and forth repeat, the most basic operation order is by the lockcenter wheel of the third round of the fourth round, the reaction of the wheel will then bounce the horse back to in position a simple harmonic movement.

Manual mechanical table principle

Above, needle dialing mechanism:

the main role is to pass the external force to the original mechanism, the strip is tight, produce position energy, so that the rotation of the mechanical watch has power.

Original moving mechanism:

the original moving mechanism is mainly composed of strip issuing, strip box wheel and strip box cover. It is the elastic element that stores the force torque, which drives the swing wheel to swing continuously.

Transmission mechanism:

is composed of some gear shaft and gear piece, the torque of the original mechanism to the escapement mechanism to drive the pointer to shift.

Capement adjustment mechanism:

using the escapement of the escapement teeth and fork tile, the firing torque to the speed adjustment component, is the firing torque to relax.

Pointer:

composed of second needle, split needle and time needle.

The above five parts of the institutions jointly form the working principle of the manual mechanical watch.

Automatic mechanical table principle

Automatic mechanical table is a modification of manual mechanical table, where a pendulum is added to the table; when worn, the pendulum in the table can ETA 2840 automatic movement due to the wrist movement, and achieve the effect of upper stripe.The general automatic mechanical table still retains the function of manual strip, in other words, can still turn the crown to strip, only some cheaper automatic mechanical movement, such as Seiko 7S26,7S36 and ETA 2842, will omit this function.And because the activity of the wrist will continuously strip the watch, the automatic mechanical meter can prevent excessive clockwork to avoid clockwork damage.However, the emergence of automatic mechanical meters did not completely replace manual mechanical meters, but now automatic mechanical meters have more products than manual mechanical meters.

In recent years, there are many improvements, such as Seiko push Kinetic human electric power watch, its principle is still to the activity of the wrist leading to the rotation of power.

Automatic mechanical watch is based on the ordinary mechanical watch, adding a part of the automatic mechanism device, through the role of arm movement in daily life.The dial has "AUTOMATIC" as automatic.In the automatic mechanism, the heavy hammer (automatic swing tuo) swings the special function of the automatic upper bar by the automatic upper wheel line and the original line connection.

When you hear the watch "tick" "tick" sound like a metronome constantly swinging, the second needle on the word plate also turn with the rhythm, let us immediately feel the continuous passing of time.The rhythmic sound is caused by the swing wheel to the horse.The swing wheel system is made of alloy and reactive by swimming wire back to the horse. A perfect swing wheel is usually to swing from 225 to 270 degrees, making time forever.The above is Daisy to tell you about the principle of the mechanical table, the above said only for friends' reference.
