In 1923, Kazakhstan Wood, passing pleasure see children playing seesaw , inspiring the invention of movement on the back of the central place automatically Tuo , but he has not used bearing type , the central axis of only one , can not play a supporting role . Strauss ends is enough iron hit the wall bounce , called the collision Tuo . Poor efficiency of the chain in this way , then other brands (such as OMEGA 4 , 50 years in the constellation ) are switching to the spring , providing a stronger reaction .
2 automatic compensation
Temperature on the mechanical watch has a negative effect because the temperature would change the flexibility of steel as the material of the hairspring balance wheel deceleration will cause high temperatures will accelerate the British JOHN ARNOLD low invented truncated bimetallic compensation balance wheel can be against that period the temperature of the steel gossamer Affect the balance of steel edges formed by the two metals within the outside temperature is high, copper brass have a high coefficient of expansion than the steel that he forced the balance of the truncated I should turn reduces the balance of the radius of its home fast for a compensation gossamer Elongation temperature, low balance outside the ring with open balance wheel slows down ( a lot of high-priced watch with the map you are optimistic about their Zhaozhao recognition simply means that balance is a broken ring of two fracture )
3 distribution agencies and counter ( escapement ) .
Escapement is a pull on the wheel out and oscillators ( Speed bodies) organizations . Its function is when the oscillator through the dead point, a small amount of energy allocated to the oscillator . "Dead spots " in the definition of the oscillator stops resting position occupied . Startup, the oscillator from the dead point swing , each swing , to be torn off and an escape wheel tooth , so that gear and pointer to beat a very small rotation and to the oscillator has a fixed frequency with the uniform .
Release in the escapement wheel out a very short moment , escapement stop , but only in the winding oscillator stops when the energy runs out . Also that in this short moment , round out the small amount of energy allocated to the oscillator . This can be visual from the second hand on the quiver . To date, more than 10 kinds of species known to the world development of escapement .
Today, virtually all mechanical watches are equipped with the same type of escapement , known as the " Switzerland Fork escapement . " Characterized by the seemingly riveted to a ship loading at the escape wheel and balance wheel intermediate parts between . Drill only two pieces alternately stopped escapement gear and make it stop . When the oscillator through the dead point, regardless of the direction in which it will drill tiles embedded into the disc escapement fork of the fork head . Thus , the release of a tooth escape wheel , and skip forward , while the small amount of energy to take this opportunity to the oscillator distribution .
In addition to escapement fork intermediate by contact with the oscillator short moment , the oscillator is absolutely not subject to its release into the impact of maintenance organizations . This is a school to watch can be accurately adjusted basic conditions. In the watch industry, enjoy the advantage of a rare type of escapement called the release of escapement . Fork escapement or release -type escapement . The release of the first generation type escapement watch just came in the eighteenth century only to the public.
Speed agencies or watch and clock oscillator is the real heart . In the clock , the oscillator is a pendulum protection . The governor in the watch body is a combination of two separate pieces of delicate parts . The two parts are a. balance . b. gossamer . Balance wheel is a ring round the flywheel , through arms or three arm associated with its rotation axis . Like all of the flywheel , it has a certain inertia . Gossamer is a suitable alloy film formed by the spring , the volume Archimedes springs into shape . The center has a swing axis within the piles and connected , and springs from the other end fixed to the watch outside the piles in the base . If the balance from its equilibrium position in the other direction to move in one direction , then balance the implementation of deformation in the springs on the toughness of the stress , the stress on the balance wheel of the same rotation . Such as relaxation balance , it will be because of gossamer elastic deformation of the force and restore its equilibrium position . Balance arrived dead point, is its maximum speed . By its momentum , it does not stop the swing , it swings the other one is almost dead side of the same angle.
In the case of no friction , the swing is eternal, but the presence of friction , it is necessary to the maintenance of all these parts to reduce friction to the possibility of swinging added . Balance wheel - gossamer moment when almost so . Ie, the duration of swing and swing is not associated . All watchmaker made every effort to maintain the isochronous nature .
To date, more or less to reduce the causes of these qualitative changes . Friction as the axle joints , balance wheel and hairspring balance error , escapement , temperature, magnetic effects and so on .
In watches , the governor body beat frequency is the number per hour per trip turn depend . Alternating with each escape wheel tooth Road, a corresponding . With the most frequency is 18000a / h (2.5 Hz ), 21600 a / h (3 Hz ) and 28800 a / h (4 Hz). At present, the watch manufacturer popular 28800 a / h frequency .
Watch a small return is small, compact machine can be seen , this, balance , springs parts, is really quite an art , modern common mechanical watch technology, Datong watershed outside the most obvious result from the material , the general to the alloy, and Bimetallic compensation pendulum swing is a lotus , light pendulum, weights pendulum, double pendulum , etc. of metal cut off , adjust the speed of a simple pin , gooseneck tuning, fine tuning screw , no Ricardo gossamer , swing arm material number Weight , adjust the different internal and external piles , gossamer last paragraph of the different curves , which should be combined with a precise number of species in order to ensure stability of the frequency change ah , that is simply different and separate the availability of a variety of shock absorber , if coupled with capture Longitudinal changes in which large , small -hours for a standard , stable , long time , the United States , a purpose various means , so funny .
