What are the factors that affect the timing accuracy of mechanical watch?
What are the factors that affect the timing accuracy of mechanical watch? Watchmen invented a timepiece that can make a bell like a church, that is, a mechanical watch.Why is quartz electronic watch accurate than mechanical watches? Watch is one of the smallest, stronger, and most precise machines invented by humans.In order to maintain the time accuracy of the mechanical watch, pay attention to the following five situations.
1. Friction
The friction is usually positive and negative. It has a positive one aspect, such as friction wheels, automatic scraps and cracks, screw self -locking, etc. On the other handThe damage of the parts affects the timing.Common solutions: improve the lubrication conditions, choose different lubricating oil according to different requirements; use gem bearing or pads; improve the gear surface conditions, including scientific co -teeth and improve surface flickering, but generally generallyThe teeth are not lubricated (in this case, the resistance of lubricating oil stickiness may be higher than friction).
2. Temperature effect
The impact of temperature is mainly manifested in two aspects: First, temperature changes will travel the working length of the hairspring, while changing the inertia of the ship can directly affect the timing accuracy; second, temperature changes will affect the viscosity of lubricating oil, affect the transmission efficiency, so as to thus, so as to thusIt affects timing.In this regard, the following methods can be adopted: the opening dual-metal temperature compensation for the swimming system is adopted; the special alloy material is used to make the hairspring and swing wheel to make it in the working temperature area (8 ° -38 °).Point temperature compensation.The standard lubricating oil is used for extreme temperature conditions, such as the world -famous Omega moon landing table, with non -lubricating or solid lubrication.
3. Travel balance
Generally, the center of gravity changes with the change of the corner of the swing wheel. Under the action of gravity, it will produce position errors.The solution is: use Breguet Travel, the center shrinks, and the center of gravity does not change with the corner; the cylindrical trace of the Felipop end -end curve is used on the upper and lower symmetrical use; the use of straight lines; in the history, some people have used spherical scarfs, with superior performance, but the craftsmanship is very poor, but the process is very poor., Rarely practical application.
4. External impact
It is the various influences from the outside of the watch, depending on the working environment of the clock.The often used measures are: shock -proof design, waterproof design, magnetic anti -magnetic design, additional protection shell, etc.The universal section is often used on the precision navigation clock, so that the navigation clock can maintain the level in the bumps.
5. Fast and slow needle
Fast and slow needles are a economic structure that facilitates school hours, but theoretical and practice confirms that it will affect the equivalent of the system and may also have poor bit. These timing errors are randomly random and cannot be compensated or offset.The solutions are: minimize the spacing of fast and slow needle internally and outside; but the best way is to not have a fast and slow needle, and adjust the speed and slowness by adjusting the inertia of the ship.
