Escapement

[ldemik]

Watched all the videos, understand all the concepts, made my first gears today with great success! Now I'm looking at producing my first escapement. My understanding, which could very well be wrong, is that if the pendulum swings it will produce it's own kinetic energy as the escapement transfers the force during the swing. That being said it will continue swinging indefinitely until something wears out or breaks. OR does it need some type of weight that is rolled on a shaft to "help" it?  If so, is there any info or videos on making such a shaft connected pulley for size and weight  and so forth. I know the pendulum can be produced in GM, What am I missing?
Thanks

start here:

Look for animations here:

Then come back and tell us how clocks work.

Thanks but no thanks, I watched all videos on Youtube and saw several grasshopper escapement without any outside assistance. No pulleys, no springs, but they also didn't have any load attached to them. This is what is driving my question. If indeed I need to assist my escapement, is there a formula or a video on setting up the pulley, ratchet, spring, or is it completely random? Your last comment has no place here.

Idemik;


Glad to see you were  successful at making your first gear, congrats, hopefully you'll have a working clock soon. As to your escapement question, any pendulum swing will always loses a bit of energy in every swing, that is why we have a main spring to re-add this energy back to the system. So in a nutshell, when the spring winds out, the pendulum eventually stops. In order to add energy back to your system, you can do this by using weights, a spring or electronics, however you do need this energy to keep it moving. I suggest you view our escapement video, it was recorded via an old version of Gearotic, but the principle remains the same.

thank you,  It appears to me that I'll be doing some trial and error, nothing new as I said my first go at this was a great success, and it encourages me to move forward.  A clock might be in the far future, just making the art form of a one of a kind movement is all I am after today. Something simple first!  As they say KISS.

Right on Idemik, keeping it simple often adds up to bigger things in the end..  I'm sure you'll do fine, and never forget to make it fun..
