< p > in ruby was found and application in mechanical clocks to improve the runtime component anti wear performance before,
http://www.bagsbagu.com, movement escapement, pendulum Tuo and gear in the gear axis of rotation is directly and brass main plate or splint is connected. Movement process, because the speed is very high and the friction coefficient is great, the pressure of each axis to bring the pressure is very large, it is easy to cause wear. At the same time, in the absence of any protective measures, the dust in the air is easy to invade into the internal movement. The micro silica particles in the dust, which can cause serious wear and tear of the gear shaft and the transmission system, which seriously affect the life of the machine.
In the later research,
has tried to use some additional components to protect the movement, such as adding a replaceable sleeve between the bearing and the splint, which can be reduced to a certain extent. But the new problem is very fast: although in the protection of the casing, the movement of the damage to the beginning to reduce, but the use of ordinary materials produced by the casing is very fast,www.topwatchbest.com, need to change, so not only trouble, but also greatly increased the maintenance costs of the clock.
the problem was resolved in early eighteenth Century. Some mathematicians and astronomers have found a material that is more rigid than the quartz grains, which can reduce the friction and damage caused by the operation of the clock. This material is a ruby, a kind of corundum, the hardness of a little less than the diamond, enough to withstand the dust of the quartz particles caused by friction.
however, the natural ruby contains a lot of impurities, and the price is very expensive. In order to reduce the cost,http://www.fashion-chrono.com, the use of the texture of the poor can only be used to produce the axis of the eye.
< p > 1885, three scientists by melting the natural ruby powder and potassium dichromate synthesis, to create a ruby Geneva ". In 1892, one of the scientists of the assistant, the French chemist Verneuil Auguste invented the flame melting method, so that artificial Ruby become possible. After more than a decade of hard work, Verneuil Auguste finally produced a man-made ruby in 1904, and can be mass production. Artificial ruby in appearance, composition and hardness of the same with natural ruby, and even as a result does not contain any impurities, artificial ruby is more wearable than ordinary natural ruby. Starting in 1940, artificial Ruby began to spread throughout the industry.
in addition to the characteristics of compression, abrasion resistance, ruby in the movement of the role, but also the performance of the decoration and other aspects. For example, in order to pursue the movement of the machine gorgeous, in order to pursue the appearance of the movement of the red, the red on the periphery of the "gold"".
