can you work out how many turns before one of the pairs will return to its starting position?
repeat this for every pair. then find the lowest common multiple of those numbers
Hi, this is for a project I'm building (See Attached Drawing). Each wheel represents a gear with the amount of teeth as labeled.
Q. How many turns of the handle until all the gears return back to their original configuration.
I'd like to see the Equation used since the actual project will have many more gear sets.
Everything I try confuses me since adding more gear sets with the same ratio to the shaft wouldn't change how many turns until it repeats.
Thanks in advance for any efforts.
Using the 20/10 gear-set as an example, you would reduce that to 2:1 and you'd have to turn the 10 wheel 2 times to make the 20 wheel turn Once.
so with the 16/15 gear set it would take 16 turns if driving the 15 wheel.
therefore ,since they are already reduced, it should be 16*17*13*11= 38896.
(its 5am having trouble forming words)
This doesn't seem to make sense either cause it doesn't change my answer if I change the teeth on the drive wheels. so I'll guess its something like 720720
this seems like it should be straight forward.
