Telling you the precise elements of mechanical watches (on)

Vibration cycle For example, in a mechanical watch , a balance spring system with a vibration frequency of 21,600 times per hour and a vibration period of 1/3 second is used as an example. Supposing that the escapement piece has 20 teeth, the balance spring system vibrates once and the escapement piece Will turn a tooth, then the escapement wheel rotation time required for the (1/3) * 20 = (20/3) seconds, because the escapement pinion and the escapement wheel pieces are riveted together, Escapement pinion rotation time required for a week is 20/3 seconds, and then set the second wheel and pinion gear meshing, both the transmission ratio of 90/10, so the second wheel rotation time required for the ( 20/3) * (90/10) = 60 seconds. In addition, the existing mechanical watches balance wheel hairspring system vibration frequency is 28,800 times an hour, the vibration period of 1/4 seconds, interested friends can calculate the speed of the second wheel according to the above ideas. Balance wheel parts It consists of a balance wheel, a pendulum shaft and a double disc member. The A-position is a pendulum shaft tip that is matched with a gemstone bearing in the pedestal assembly of the pedestal. The B-position is a gem bearing phase with the pendulum shaft tip; C position is balance, it is this system the most important part, since mechanical watches was born there have been many types of balance, because the balance wheel will directly affect the mechanical watch accuracy of travel time, so watch Designers must take the initiative to eliminate or minimize the factors that affect the balance, especially the environmental impact of the most prominent, which led to the production of balance wheel materials must be used over the centuries have summarized the special material, in addition Its shape is also specially designed, these are for the balance wheel in the movement to resist the adverse effects from the external factors that affect their normal movement, such as temperature compensation balance wheel, self-compensating balance spring, balance beryllium alloy wheel And variable inertia balance wheel, in which the variable inertia moment balance wheel is a rather special balance wheel, in order to have a special structure is non-card balance wheel hairspring System, which I will later in detail for everyone to do; D position is a double disc components, which includes a double disc and mounted on it above the disc nail, this part played a special role I have been in the previous Period "mechanical watch escapement" made a description; Gossamer parts Which comprises a hairspring and a triangular inner pile, wherein the position A is a central hole of the pile which is fixed with the balance shaft; the position B is the opening of the flank of the triangular pile cooperating with the inner end of the hairspring, Gossamer matched, and the so-called triangular pile is based on its shape to the name, is currently the most widely used pile, in addition to a pile is circular, as the name suggests is called circular pile, as a result of Compared with the triangular pile it can not perfectly fit the inner end of the hairspring shortcomings, the application is relatively small; C position is the hairspring, its shape is the Archimedes spiral, also known as the vortex line; D position is spring The outer curve is not part of the vortex but rather is a specially designed arc with several broken lines. The purpose of this design is to compare the accuracy of the timepiece with the adjustment mechanical wristwatch Staples the most outer end of the pile can be better together; Speed ​​control components Which comprises a gossamer parts and balance wheel parts, A position is the stud on the gossamer parts and the balance of the balance wheel parts fixed as one; B position is the balance wheel, the balance wheel is provided with a plurality of screws belonging to the flower The balance wheel; C position and D position have already mentioned their role in the front, and put them together is the need for a fixed design point of view, in the time book is called the roll angle, this angle is based on the balance spring The initial curve between the initial end of the pile and the spring wire at the outer end of the balance spring and the angle between the connection of the outer end of the pile and the curve of the outer post are the winding angles of the hairspring. The included angle is also designed so that it determines the consistency of the two vibrational periods around the balance spring system; Plywood components It consists of pendulum plate, shock absorber assembly, needle and needle components and post pile ring components, A position is the pendulum plate, which is engraved with the sign and the scale of its role is to identify the speed of the needle to adjust the speed of the specific The working principle will be introduced later; B position is the shock absorber, which is mounted on the pendulum plate as a pendulum axis of the upper bearing, but also played a role in protecting the axis of the balance shaft; C position is the needle unit, which includes The speed and the needle as well as embedded in the end of the outer clip and the two thinner clip, which has a bulge at the tail of the clip, its role is to stop the hairspring during the shock will not be separated, Is to control the hairspring axial direction, and the gap formed between the two inner clip is left hairspring, making hairspring can be boxed inside, which is limited to the balance spring radial movement; Which comprises a pile ring and an outer pile pipe embedded at the end, and a screwed external pile with an opening for the purpose of bonding the outermost end of the hairspring through a glue. The setting of the pile component is that In order to adjust the position of the outer curve of the hairspring so as to ensure that the center of the hairspring is coaxial with the center of the pendulum axis, the time taken for the whole vibration cycle to swing from left to right is as uniform as possible.
