1 hit thallium
In 1923, Kazakhstan passed special pleasure to see kids live to play seesaw, inspired the invention automatically placed in the center of the movement on the back of Tuo, but he has not used bearing type, the central axis of only one, can not play a supporting role. Tuo is a hard enough at both ends, hit the rebound wall, known as Tuo hit. Poor efficiency of the chain in this way, then other brands (such as OMEGA the forties and fifties of the constellation) are switched to the spring, providing a stronger reaction.
2 automatic compensation
Temperature on the mechanical watch has a negative effect because the temperature will change the elasticity of steel as the material of the hairspring balance wheel deceleration will cause high temperatures will accelerate the British JOHN ARNOLD low truncated invented bimetallic balance wheel can be compensated against the temperature of the steel during the gossamer placed round the edge of the metal formed by two steel outside temperature is high in copper brass has a high coefficient of expansion than steel, he was forced to cut balance wheel should turn reduces the population balance wheel radius compensation to a gossamer home soon elongation temperature is low relative to outer ring of the balance wheel balance wheel slows opening (many in the high figure on the watch you have to use their own recognized look promising, that is to balance a simple ring is broken there are two fracture )
3, distribution agencies and counter (escapement).
Escapement is a pull on the wheel column and oscillators (Speed bodies) organizations. Its function is that whenever the oscillator through the dead point, a small amount of energy allocated to the oscillator. "Dead spots" in the definition of that occupied by the oscillator stops resting position. Startup, the oscillator from the dead point swing, each swing, must be torn off and an escape wheel tooth, the gear train and the beating of a pointer to a very small rotation has a uniform and to the oscillator frequency with the move.
The release of the escapement wheel out of a very short moment, escapement stop, but only in the spring oscillator stops when the energy runs out. In that short moment that is, round out the small amount of energy allocated to the oscillator. This can be visual from the second hand on the quiver. So far, more than a dozen types of escapement developed world.
Today, virtually all mechanical watches are equipped with the same type of escapement, known as the "Switzerland Fork escapement." Characterized by the ship looks like a rivet installed in the escape wheel and balance wheel in the middle between the parts. Drill only two pieces alternately stopped escapement gear and make it stop. When the oscillator through the dead point, no matter which direction it will drill tiles embedded in the disc fork escapement fork head. Thus, the release of a tooth escape wheel, and skip forward at the same time, take the opportunity to allocate small amounts of energy to the oscillator.
In addition to escapement fork head through the middle of a brief moment of contact with the oscillator, the oscillator is absolutely not subject to its release into the impact of maintenance organizations. This is the watch to get an accurate calibrated basic conditions. In the watch industry, enjoy the advantage of a rare type of escapement called the release of escapement. Fork escapement escapement is released. The release of the first generation of watch escapement is only in the eighteenth century only come out in public.
4, Speed institutions (oscillator)
Speed agencies or watch and clock oscillator is the real heart. In the clock, the oscillator is a pendulum security. The governor in the watch body is a combination of two separate pieces of delicate parts. A. The two parts are placed round. b. gossamer. Balance wheel is a ring round the flywheel, through arms or three arm associated with its axis of rotation. Like all of the flywheel, it has a certain inertia. Gossamer is a piece by the composition of the alloy for spring, rolled into shape Archimedes springs. The center has a swing axis of the piles and connected, while the springs outside the piles from the other end of the base of the watch fixed. Such as the balance wheel in one direction from its equilibrium position in the other direction, then in the springs balance the toughness of deformation on the implementation of the stress, the stress equivalent to the balance wheel rotation. Such as the relaxation of the balance wheel, it will be because of deformation of elastic springs force and restore its equilibrium position. Balance wheel when the dead arrived, is its maximum speed. By means of its momentum, it does not stop the swing, it is an almost dead point swing the other side of the same angle.
In the frictionless case, the swing is eternal, but because of 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 - such as gossamer moment when almost. Ie, the duration of swing and swing is not associated. Try to keep it all watchmakers are isochronous.
So far, more or less to reduce the causes of these qualitative changes. Tenon as the axis of friction, balance wheel and hairspring balance error, escapement, temperature, magnetic, and so the impact.
In the watch, the governor body beat frequency by a single stroke per hour depending on the number of the alternate. Each turn of the escapement wheel and the road corresponding to a tooth. 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, the balance wheel, hairspring part, is really quite an art, modern common mechanical watch technology, this watershed outside Datong most obvious, from the material, the general to the alloy, and bi-metal compensation pendulum swing is a lotus, light swing, swing weights, pendulum and other bi-metallic cut, adjust the speed of a simple pin, gooseneck tuning, spiral tuning, no card, sprung, the number of swing arm material, weight and adjust the different internal and external piles, gossamer last paragraph of the curve is different from that in conjunction with a number of species in order to ensure stability of changes in the frequency precision ah, that is simply different and whether the separation of a variety of shock, if coupled with the capture Longitudinal changes in that large, accounting for a little while accurate, swatch, long time, the United States, a purpose various means, so funny.
