Automatic chain system works

Mechanical automatic chain system operation principle is only one, is to use the movement of the wearer’s arm, make automatic in the system with gravity weight (metal is placed swing tuo), metal put tuo is not within the period of rotation so as to promote the system of lever, gear chain on the spring. At the moment, in the form of the design for replica hublot watches is different, the basic concept remains the same.


Only different mechanical automatic chain system only JLC Atoms air clock, using temperature change to make internal metal strip shape, the driving gear is given priority to spring on the chain, but not used for watches, otherwise will become “simply, make the gods cry”! System structure: all kinds of automatic chain collision tuo is between manual products, between the chain and automatic chain on one-way chain design, chain on performance is not perfect, using metal pendulum tuo in the movement chain named “bump” give priority to spring back and forth.

Bump tuo some teeth axis (red), direct drive a swing system teeth (yellow), so that they don’t swing up and down about 50 to 60 degrees or so, during the rotation axis core (blue) at the bottom of the gear chain mainly clockwork, inclined teeth (green) to ensure that the one-way chain. Chain performance is poor, “hit” to the adversary is not filled with chain.
Swing type automatic chain system: using the rotation of the pendulum tuo, promote a set of gears can be from side to side, the bidirectional mainly clockwork on chain. Is placed at the bottom of the vedas teeth (red) direct drive pinion before swinging gear set round (yellow) the power to give priority to spring on the chain.

When put tuo to another direction, swing gear set before pinion (red) for reversing work can only, swaying drive gears after pinion round (yellow) the power to give priority to spring on the chain.

Seiko use Magic Lever automatic chain system, the design is very simple, reliable and can be quickly dominated clockwork chain, but the torsion weak, when the mainspring has half full chain, may be more difficult to chain.

Magic Lever structure is very simple, a ‘Y’ in the shape of a Lever connected directly put tuo axis with the chain gear; Magic Lever is to set on the axial eccentric (red), when put tuo rotation, ‘Y’ shape Lever will not paragraph on “under the” Zuo Zuo chain gear (yellow/blue) chain on the spring.
IWC automatic chain system: woodpeckers principle is automatically put tuo behind one eccentric CAM, CAM rotation between two pulleys in “w” (blue) so as to promote the whole system, lever principle that system within the “bird tsui (black)” and “short bird mouth” (red) relative to move up and down continuously, the formation of “bird tip down”, “short bird mouth slides up”; “Short bird tsui” down, “long bird mouth” sliding upwards and kept pulling inclined teeth chain wheel (yellow) spring.

The reversing wheel automatic chain system: ETA automatic chain system, using the teeth (red) is placed at the bottom of the vedas, connected to the upper reversing wheel gear (yellow), turn left/right the reversing wheel whether put tuo, chain can give priority to spring.

Old girard-perregaux chain system on the reversing wheel automatically, ETA principle is the same, and both the reversing wheel for double design, very close to the upper teeth (blue), but does not only connect to put tuo bottom teeth, the lower is connected; The reversing wheel must be designed to turn up and down one of the chronological correlation, inverse time and space; Another on or off the inverse correlation, chronological idling. When put tuo reverse rotation (red), both the reversing wheel upper chronological rotation (yellow), right the reversing wheel moving up and down, turns the lower as chronological (black), pushed through the left turn the reversing bye lower inverse rotation (green).

When put tuo chronological rotation (red), both the reversing wheel upper reverse rotation (yellow), left the reversing wheel moving up and down, make the lower reverse rotation (green), the reversing wheel right lower chronological idling (black). In this way, the reversing wheel left lower forever when reverse rotation (green) chain on the spring.
Rolex on automatic chain system: the system principle of the reversing wheel is the same as the ETA, but different structures; Appearance will only find two red big gear in the rotation, but still can be two-way chain, the reason is the lower non-return wheel was red bull gear cover, from the bottom to see.

Put tuo power first sent to the first big red gear (blue), when the internal/external gear synchronous axis in the pinion (black) will drive the copper gear mainly clockwork chain (green); At this point, the other red bull gear in the reverse gear wheel will be bronze belt idling (black).
Semi-automatic system/one-way chain: as long as the system automatically installs a reversing wheel only (e.g. ETA7750) or use an oblique teeth (e.g. JLC 899) can be made into one-way automatic chain. Note: do not think the bidirectional automatic chain must be better than one-way automatic chain. Chain system of two-way efficiency when just on automatic list box will chain is better than a one-way, when worn on the hand, one-way bi-directional than at any time; Because people can have “Yin/ruthless forces”, these forces can make simple structure on the one-way chain more efficient.
