Re: Best amount of sprocket teeth

Remember its not really about the number of teeth.. its about the diameter of the gear.

In matched gears this can be equated to the number of teeth.

You want to figure out the ratio you need between motor and output and then figure out a way to get that mechanical advantage...

You don't have to use gears or teeth at all..you may also have to use several gears to get where you want..(ie gear box..)

Better to think of it as the ratio you want...and not the number of teeth...

Good luck with your design!!
