Gear Chains (more than 2 gears together) Suppose you have 30 gears (holy squirrels!), all in order, like in the image above. How in the monkies do you calculate the gearing ratio of that behemoth? Easy. Ignore all the gears in between the very first and very last gear. If the diameter of the first gear is 2 inches, and the diameter of the last is 1 inch, you have a 2:1 ratio. The gears in between do not matter. Now what direction does the last gear rotate? Easy, you have an even number of gears, so it is counter-rotational of the first gear. What efficiency do you have? Well thats: effienciency_total = gear_type_efficiency ^ (# of gears - 1) = .9 ^ (29) = 4.7 %If instead you used 5 gears, you would have: effienciency_total = .9 ^ (4) = 65.6 %

Consider a two-gear setup: 10 and 20 tooth.

No offense, maybe it's just me, but I don't think anybody answered my question except bens. I don't mean to be rude. Please don't take this the wrong way.

By compound gears do you mean gears of the same size and tooths in a row?

If I put the biggest gear on the motor, then the second smallest gear in between the motor and axle, and the very smallest on the drive axle itself, won't the speed increase every time?

Thanks so much guys, what would I do without you.

No more no less.Thanks so much guys, what would I do without you.

major in english or history

Is 30+20tooth combination still better than any three gear combination.

First, we will have a competition for speed, then hill climbing. So, for hill climbing, I just need to switch the gears right? Or will a three gear combination work better for torque?

If the torque of my car is sacrificed as much as possible to the increase of speed, won't my car like not move at all because there's not sufficient torque. Or maybe it will be slower because it's torque is weak?

What I'd like to know is (if you haven't already told me and it passed by me) how to figure out the torque and speed of my car by just knowing the gear ratio and the mass. I don't need to figure out how much I need for it to climb or go fastest, but to calculate the speed for each one and get the fastest one.
