Mechanical watch mechanism design code function zero

The so-called "design code" function, meaning the stopwatch function, which can be used to count time, this feature is widely used for scientific experiments, sports, ranging in speed. Now watch with a design more functional code, including quartz, no matter whether you live on the use, at least it was "three-pin three" style dial hands, plus there are many tables to definitely give people with complex, high-end feel.

    Needless to say, really count code function is the complex structure of the watch in one of all, watch the time with different classes of instructions, which are relying on each cycle of operation in order to press the different tables to be completed, that is, "to start, stop
, zero. " Under normal circumstances, it can record from 0.1 seconds to 12 hours between the time (in theory), time to watch it and move instructions in parallel, self-contained, non-interference of each other, by the people to control when the action ; its power comes from a common spring, watch the pendulum from the center frequency and a large second hand following the second round of the fine teeth determines the measurement accuracy,

    Few described the structure and function of design code works article to clear it popular, not so easy; in fact, no matter what kind of design, its structure is very similar decomposition classified, it is the three major components: 1, column-wheel; 2, all the pointers below zero, "Peach Cam"; 3, the operating lever and spring there is the positioning of the spring assembly related, including plywood on the axis of rotation and a large number of
screws.

    Watch carefully observe the count code structure, you will see the clouds are layered rod spring, are starting positioning, manipulation and pressure, some very slender rod spring, oddly shaped, are outflanking, playing interspersed combat-type, some with "joint", hook arm, which push the buttons of the manual pressure, transmitted to the column-wheel, column-wheel is a vertical display of the original cylindrical gear (column wheel), watch machine heart in addition to "lie down round", but no longer with similar, and it and the "lying round" as a spur and helical gear, straight teeth for positioning control (straight-tooth cross-section is a class of triangle), and helical also used to pull it rotates positioning (can only do one-way rotation), it's straight teeth number from 5-9 in both, depending on the stopwatch function and design. Column-wheel is actually a mystery, because this structure has emerged in the early years of the watch, at least have been born 100 years, and human knowledge of science and technology and much higher than that time.

    Other parts of the heart and watch a different machine, such as drawing file parts, pull and push forward the table to manipulate it, and then control it from the next and which engage the gear, transmission and whom; column-wheel control is not just a step, it at least 2 or 3 tube steps, coordination and at the same time, it is linked to the main control, like a 2X2 or 3X3 circuit switches, main controls, including code-pin of seconds, minutes, same time disengage the wheel when the pointer and engagement, there is a zero with a large lever, the ends are similar to the guillotine, guillotine can have 2 or 3, the meshing gear torn off quickly after the voltage, respectively, to zero in the pointer hit the cam wheel on.

    Account code structure, most of them do surface in the movement assembly, but there are to do in the face of the dial assembly, to engage in what is now add "modules" in the heart of a model-based machine "Sidaluanjian" on and building in the use of prefabricated panels forming the same. As the saying goes, "nail is the nail, rivet is riveting," it is the same, bar the bar, spring is spring, step outside restrain the screw, the number of parts was too much, it seems that looks messy, intertwined, are all self- doors to the "nuclear family household." Total time of all the wheels on the following indicators have "Peach Cam", which is the coupling and also partial core, smooth side, the wheel is critical. When the guillotine cut back to zero when these "Peach Cam" are "beheading" is called with, to play them Diliu turn (left to right are possible), especially similar to the present Gaddafi situation, this time they are put out floating shelf, free state, the original of all the "connection and relationships," regardless of it all, which it must produce rotation, the final stop to the arm position of the shortest and flat, That is, all the pointer to zero position.

    Structure with column-wheel chronograph are more complex, there is also a distortion to make improvements, such as ETA7750 movement, it is only the upper and lower parts of this three-cam piece, by stamping and welding current shape, the relative movement can do some thin , the structure is simplified a lot, so some people commented it, it (ETA7750) is a "poor man's chronograph" movement.

    Chronograph to do regular maintenance is important to wash the oil, it needs to maintain that structure in a lot of good lubrication of the parts, from the use of operation code table, you can feel, timing requires a lot of strength to push the button, it completely is to rely on the lever under the pressure push the button, the action parts will operate
