Gear Trains as per link
Posted: Tue Apr 26, 2022 4:52 pm
Hey G'day,
I rear my ugly head every so often..
My query is https://www.youtube.com/watch?v=fCBhN5yTKDU at about 1:30sec the video gets into the meat of my question. Can you build a gear train using gearotic as per video? Just so you all know Orrery builders are an endangered species, only two left in the UK.. and who knows if the rest of the world even knows what an orrery is or tellurium.
I don't know of any makers here in Australia either, I have seen a few people make kits that are sold on etsy but these are generally copies of copies with slight variations of one another.
Staines & Son I think are the only people that make them today and sell across the pond to the rest of the world.
https://www.youtube.com/watch?v=nlgyXY3vPd4 is one of the nicest models/concepts I have seen to date, there's just something absolutely beautiful about watching gears turn, not really going anywhere. Like a dog chasing its tail round and round they go yet I could sit and watch all day some of the machinations I find on you tube. Gears need not just be functional they can be exotically artistic as well.
There a lot and not a lot of information on the web regarding the math for what type of gear size you need to simulate a solar year for Earth, Mars etc etc etc that's not the issue. Building the orrery is not an issue, buying/making/printing of gears not really an issue. The math and formulas for gear ratio's is pretty well established.
BUT but but but, simulating the movement is an issue.
You can simulate gear trains for clocks, an orrery is sort of a clock with a few extra here and there's and maybe an unusual link to an other gear here and there as well. Hence my question.
If we can save the blue speckled galah from the wind turbines lets have a crack at saving orrery makers. :)
Please excuse the tongue and cheek.
Regards from the colonies downunder,
Steve
