Looks like a glorified lever escapement to me. Beat jewel touches lever fork on anti-clockwise rotation at the end of it`s amplitude.. Not even an overcoil. Someone is kidding someone. Patek failed to make the co-axial escapement.
I cannot understand how this escapement offers anything over the concentric full rim balance wheel made from metal with a low expansion and contraction coefficient. The HS also !!. Temperature is almost always the enemy !.
Alagathevictor, this is a massively oversized model of a watch escapement, not of an automatic winding device. I suppose you could say that there are similar features between the two in some respects: in an automatic rotor, a weight swings off a central pivot, swaying back and forth, but it's motions are random. In a clock like you referred to, the pendulum sways very precisely, as determined by its length and by the force of gravity, same as a watch escapement (a hairspring replacing gravity).
Since a few weeks totally intrigued by watch and clock escapements.... See here my 3D printed mini version: ru-vid.comlsmrTDvrY_w It was the 1st I made... PL.
they research and develop advanced materials that have the same friction characteristics as lubricated steel but does not require lubrication, "silinvar" : silicon invariable the rest it's a conventional swiss lever escapement mechanism
How can the balance wheel replenish energy? If not, the magnitude of its movement will continue decline, but my watch can work without stop for several days. I can't figure out the reason.
energy comes via the wheel on the left . No idea how they did it here, probably a small electric motor. The spring, and the rest that we see here is to control the timing by blocking the rotary motion for a while. This isn't a clock, it's a speed controller component for a clock .
Jose Liu Energy comes from the gear on the left. The balance wheel and spring act only as regulating devices. The energy is stored within the power coil which would come from the gear train eventually ending on the gear you see on the left. It doesn't unspin in an instant thanks to the balance and spring which regulates the unspinning. Watches work like fountain pens. It's a controlled leak.
Thank you very much! This is a model of balance hair spring system, an important part of a mechanical watch . The left part is somewhat like an "escapment" which replenish energy to the balance wheel each time it was knocked and released. The period of the balance wheel- hairspring assemly is determined by its structrul parameters, therefore control the energy dissipation rate of the left part, that is how fast the left part. And thus , the enery stored in the mainspring is released at a constant rate.
the only breakthrough of the modern escapement is the braking system in spring drive movement from Seiko, the rest just the modification of what we have,
The escapement assembly ensures that the clock ticks on in an uniformed manner. Without the assembly, the mainspring would release all the energy as quickly as possible. The balance wheel goes back and forth allowing the gear on the left to advance one tooth per swing. In a wrist watch or a pocket watch this motion is governed by the coil seen on the right. In a grandfather clock this is governed by a pendulum. The main spring is another spring coil in the watch which drives everything. In a grandfather clock they are replaced by weights that you wind up.
This escapement shares the same purpose as all escapement. Obviously this one is there to show people so it is enlarged and probably not regulating a clock. Not sure what you are asking. If you are asking what is improved by this design then I don't know. Probably more compact or more precise than the traditional design.
Seems a typical eh swiss lever escapement, cant see clearer the exact details of the exit and entrance pallets. Major difference is the balance wheel, isn't a wheel at all, it's a weighted rod that rotates around it's center of mass.
this is probably the most used watch escapement, Some reasons its used for watches are, it provides recoil/draw which is back pressure so tthat the lever won't move if it is shaken etc, and won't jam the watch casuing it to abruptly stop. Also it does a fairly good job of reducing impact on pallets etc. these escapement are typically good for 38 to 44 hours and can hold times of +- 10 seconds or so per year (don't remember exact numbers just ball park average).
