Mechanical watch
Mechanical watch can normally be divided into the following two categories: a hand chain and an automatic uplink watch. The power sources of both machines are driven by hair strips inside the core, driving gears and thus the instrumentation, although the way in which the power source is generated varies. The mechanical watch on hand is hand-driven, and the core is thicker than the lower of the surface, which is relatively light. Automatically chained watches are dynamically driven by the right and right swing of the core, but relatively thicker than the hairing of the hand。
Mechanical watch - type
Manual meter
It's a watch driven by hand-strings。
The manual watch is usually used to activate the timing function of the watch by moving the crown / the head, by releasing the kinetic energy from the hairbar system. All these processes are done by mechanical principles and architecture。
A full hairline normally allows the watch to walk for more than 30 hours, up to a maximum of eight days or more (powered by two sets of hairlines). If the watch is not running, it is usually recommended that the hair be full once a day; however, too tight the hairline may cause damage to the hairbox. It has even been suggested that the timing of the meeting be used because the temperature at different times can have an impact on the timing, so that the watch can be better maintained。
Automechanical table
It is an improvement of the manual watch, where a pedestal is added; when it is worn, the pedals can rotate because of their wrist activity, so that they can have the effect of having an upper note. The normal automatic machine watch still retains the function of hand-on-branching, in other words, it can still be rotated to the top, and this function will only be omitted if some of the cheaper automechanical cores, such as 7s26, 7s36 and 2842 of eta, are refined. Moreover, since the wrist activity would continue to be marked by the watch, the automatic mechanical watch would have all the features to prevent excessive striping to avoid damage. However, the emergence of the automatic meter does not entirely replace the manual meter, except that it now produces more products than the manual meter。
Since the twentieth century, there have been a number of improvements to the automatic meter, such as the precision-pushed kinetic man-to-man electric watch, which continues to be based on the activities of the wrists leading to volto rotation and generating electricity。
Strengths and disadvantages
Advantages of the meter
Batteries need not be replaced and oil can be washed through regular maintenance for a long time。
Shortcomings of the meter
Larger than stone, errors are caused by the quality of the production and the vulnerability of the core within the surface to gravity. The mechanical chart is usually calculated on the basis of the number of seconds difference per day, while the stone watch is calculated on the basis of the number of seconds difference per month。
Rationale
The hairline is a part that provides energy to the watch and is wrapped around a box. Use the squirm slots on the axis to snap. The square of the axis is driven by the previous institution. The watch is able to walk for between 36 and 50 hours without a note. The introduction of alloy material is now almost constant, as the effect of the apparent stress of the article has often led to fractures. The hair strips store a certain amount of energy to be distributed evenly and in small quantities to oscillators. For this purpose, the energy provided is increased by the number of circles by rotating groups, which reduce the transmission power by the same proportion. The group consisted of four wheels and four gears, the latter three being held in the first three gears. In this diagram, the slash represents a tangle between the vehicles, while the line indicates that the moving elements are attached to the same axis. The first is a round-legged box. The last wheel was the tackle of the agency gear, which was held against it. The wheel is part of the distribution agency and the counter. Rounded around a box for about six hours, during which time around 3600 laps of gear and wheel were rounded. This figure represents the rate of rotation between the first and the last. This proportion remains within this range. In general, efforts are made to place gears and semi-wheels at the centre of the watch and to rotate every hour。
Watch structure
Watch gear
The gear transfer system of the watch, in particular the main wheel system, is widely used in the so-called round arc tooth. This is the result of the evolution of the line gears, which are difficult to process because of the fact that they are pure swirling, and are replaced by a circle arc, also known as the correction of the swirling gears, which allows for a minimum number of six of the gears, thus allowing for a large movement ratio of the rotors, which is extremely beneficial for reducing the diameter of the heart and for high frequency watches. Passivity is more efficient and generally reaches about 95 per cent. Owing to the small size of the watch, the energy stored in the wheeled components of a box is not significant and, if the energy is lost too much, it will have a direct impact on the quality of the watch as it moves. There is greater sensitivity to process errors. Both carving errors and centre spacing errors can cause changes in the condensation properties. Because their teeth are determined by a pair of gears and moulds, the number of teeth and moulds is different, as are rollers and hammers。

The structure of the trap is simple, and switzerland has a relatively small watch component, consisting mainly of a wheel, a forklift (including forklifts, tiles, forklifts, nails, forklifts), two disc parts (two disks, nails) and a limited nail on the main plate. However, some watches do not use a cutter, but rather do so directly from the main or forkboard. There is also a nail that is stretched out on the fork's parts and inserted into a hole in the main plate, with two wall limits. This is called a forklift, divided into two categories: straight and side fork. The first is to capture the axis of the wheel, to capture the axis of the fork, and to set the axis on a line; the second is to have some of the angles of the three holes. Although the two forms differ, their composition and rationale are identical. Mainly for medium and advanced watches。

The turbo wiring is part of a stable vibration frequency. The two components form the backbone of the watch by organically linking the moving wheel system with the trapping agency. The vibration of the turbo-wire assembly consumes a certain amount of energy, which is supplemented by the original kinetic system. The supply is large and the turbo is large; on the contrary, the supply is small in energy and the turbo is small in angle, i. E. Small in size. If the energy supplied remains constant, the swinging angle, i. E. The frame, of the wheeling silk component remains unchanged. In fact, it is impossible to supply energy without change. Because of the tight hairs above the mechanical watch that supply the power... The power of the hairs that relax their power will be smaller... And, of course, the energy that is supplied will be smaller. In addition, this energy varies from time to time by means of transmission systems and locking institutions, which are constantly changing in terms of their work characteristics, transmission efficiency and agency efficiency, and, when measured by placards or plaster recorders, the values shown are constantly volatile and are generally expressed in terms of the average of the maximum and minimum values for a given period of time。
