2nd uploader comment, thats called a hairspring

[AaronLow1]

IVE SEEN ONE OF THESE! its a hair spring timer, i took one apart when i was 8 lol

[RollaArtis]

Don't worry, your balance spring idea was used by Robert Hooke around 1670. Apparently it didn't work very well.

[Shtwc1]

This is neat!

[wowmastervenix]

hehe i was trying to make some of mine no energy powered stuff its hard to make one and yh thats how waches work lol nice vid ^^

Although the springs aren't correct, the action is. The blue gear, called the escape wheel is the last wheel on a watch's geartrain and is actually "flicking" the balance wheel making it oscillate which in turn moves the pallet (t shaped piece) and allows the escape wheel to turn one click. They cycle is repeated around 18,000 times an hour.

The software 'Phun' doesn't have the spiral spring that watch has. So, I have to substitute the spring with the only spring it has. The 'flickering' thing (the Y shaped fork at the central of the balance wheel - the big wheel) is wrong too, it should be flicking the thing at the back, but 'Phun' doesn't allow much of a 3D workings.

You did a good job. I looked all over for an animation on how the escapement works since it's so difficult to see on an actual watch.

What keeps it going? Is air friction off, or am I missing somehting¿

[MarkQP]

a motor?

[baptistepcarrara]

is it a clock

[Cru0R]

i cant say what it was but it was awesome! :D

[nawitus]

It's how pendulum clock works

[KingBobXVI]

actually its how a watch works (spring powered). Just think of the big wheel as a pendulum.

[explosif219]

what keeps the pendulum working? is there an energy transfer in the T shaped piece?

[KingBobXVI]

If you want to learn exactly how a watch works, search for this video in YouTube (copy and paste):

Cómo Funciona un Reloj Mecánico

(the thumbnail is a picture of 3 gears)

It's in English, and was produced by the Hamilton Watch Company, Even though it's old and somewhat cheesy, it's good at explaining how it works.

[engp0963]

The energy comes from the blue gear (i.e. the small directional gear at the bottom - the escape wheel). In an old clock, this escape wheel is used to drive the second hand (i.e. 60 seconds for 1 complete rev). Watches' one would be geared (1 complete rev = X seconds) because it is much faster.

In the Phun movie shown here, I've 'cheated a bit by linking it with a 'motor' at the escape wheel, giving it the energy. I have tried using a chain to pull on a heavy object, but it doesn't work well.

rly cool
