When the balance wheel in one location is affected by a certain direction of gravity, to another location will be affected by another direction of gravity, framework constantly turning, the position of the balance wheel
also change, to accept the influence of various direction; In other words, in the macro level, the influence of various direction will offset each other, is equal to no effect.The tourbillon watches originality lies in the fact that the central escapement clock in a frame (Carriage),
within the framework around the axis is the axis of the balance wheel regularly do rotate 360 degrees. This way, the original escapement is fixed, so when the watches aside position change, escapement, caused the
escapement force error resulting from the different parts; When escapement continuously spin 360 degrees, will be part of the azimuth error together, offset each other, to reduce the error to the greatest extent.
Treasure pearl card Russell wrist watch
Master treasure to Los Angeles in 1795, and in 1801 patented Rgulafeur Tourbillion tourbillon watches “specification”. Due to the observatory tourbillon watches make difficult, so in the past two centuries made
hundreds of only. 1892 French Bahne Bonniksen escapement simplifies the turning device and a patent, and the named card Russell – Karrusel (namely the carrousel in English the meaning of “rotate”, also called eccentric tourbillon watches).Barroso bench of rotating speed is much slower than the tourbillon watches, according to the different design,
about 34 to 52.5 minutes while on a business trip. Despite the sacrifice accuracy, but invented in Britain the lever escapement devices in Switzerland after reinforcement structure is simplified and more superior to the original the tourbillon watches escapement devices. Since then, no CARDS degree English lever tackled longitudinal device barroso coventry city in the UK, in grams on Observatory (Kew Observatory) test and some
of the British royal navy.
The movement diagram
Although card barroso did not affect the observatory was exalted status.The tourbillon watches or not affects the tourbillon watches increasingly important application in the observatory. But in the twentieth century, is doomed to the other the tourbillon watches except lever started dying. Use more reliable lever the tourbillon watches watches began in 1930, the tourbillon watches watch as the highest observatory navigation watches. Leveraged the tourbillon watches watches also have become a observatory race, for example, in 1945, Patek Philippe launched have leveraged the tourbillon watches of weight balance wheel weights, and in 1943 to 1967 Geneva observatory exhibit dance competition, and until 1969 due to quartz watch into the observatory race ended and the upheaval.
Treasure her wrist watch
Unlike “the tourbillon watches” drive structure, the lower end of the rotating bracket “card Russell out of a hollow shaft, under which end connection round slices. Wheel engages with three gear shaft. Rotating bracket shaft through the plywood, and supported by the latter, rotating bracket and round piece of two relative end thrust surface effect. Four shaft through the rotation of the bottom of bracket and hollow shaft, round piece in a rotating stents and escapement meshing gear shaft, gear shaft outside the stents with four rounds of meshing, pass three rounds of the impulse to escape wheel. Four gear shaft through the four pieces of the longitudinal tooth axis movement to escape, pendulum shaft in the rotary bracket and four gear shaft is different. Because rotary bracket is not directly driven by four axles, so the speed of the rotary bracket
always less than four axles. “Russell” transmission design, therefore, is actually a differential planetary gear train.
The tourbillon watches and caruso contrast figure
Russell is the clock again after the tourbillon watches technology innovation, many netizens to what’s the difference between this two kinds of technology is not very clear, simple terms they have the following
1, the tourbillon watches general speed faster than card Russell;
2, the tourbillon watches parts more than Russell;
3, the tourbillon watches generally a four-wheel drive, the card Russell is five rounds;More than
4, caruso is eccentric type design, is not fixed gear rotate.
