Infinitely-Extendable Gearbox Creates Exponential Gear Ratios #stem #3dprinting #physics

[The_Takeout_Samurai]

The only bad thing is the higher gear ratio it is the more force you need to put in

Gonna go try this in Lego. I once made a 8x8 box with tons of reduction that could lift a gallon of water with a Lego motor but this could really expand that capability. Cool.

This is really helpful for high precision. The smallest movement on the fast gears makes for an infinitely smaller movement on the slow gears.

Use 23 or 25 teeth on the bigger gear. Because 24 is divisible by 8, the same teeth will always wear the same gears. It’ll wear much slower if the same teeth move around the whole gear.

Infinite increment until you hit the max stress level and need to make more windmills

[Arsectral]

We have slow gear that ends after universe ended and now we have this

[tbrooke]

This would be such a good educational tool for high school!

[DeltaModelX]

some guy made a tutorial about this for build a boat for treasure of all things, also using circle geometry calculations to make a perfect circle for the gears, truly people do anything but build boats on that game

This is exactly what I am looking for for my science project! Thank you so much! I am using steam power and need faster rotation for my generator! Thank you!

[martinshoosterman]

The idea that this is somehow hard to make without 3d printing is hilarious.

According to my calculations, if you had 359, 750, 949.6 gears, just 3 km/h would be enough for the last one to spin at the speed of light
edit: wow 21 comments and 100 likes tnx and yes i made a mistake in reality the force to turn the one wheel would take a verry verry mutch force to turn and the plastic would brake but if we had a unbrakebal wheel and enough force to spin the frst wheel 3km/h the last one would go speed of light but the amaunt will of energy needet is extremle unefectivve to do some crazy things wnit it

[darwfer]

I genuinely could not comprehend gear ratios but that long stick vs short stick analogy made it make sense finally

[HailStan]

Gear ratios are wild to think about. Almost anyone could make a machine that if never degraded or stopped (aka hypothetically) could not only out live them, but the heat death of the universe (again, if indestructible.) It always makes me have a mini crisis when I think about it.

Infinitly stackable gear box
Minecraft create mod players joined the call

[Taskmeister]

It's infinite until torque says no, gears are funny.

[Snakeybloo]

I remember figuring this out once in a robotics class to make the robot faster. Good times.

[lordbaconweeb]

Yo the phrase "they dont add. They multiply" is powerful!

[Joenzinator]

I did the math, and if you stacked 20 of these, and were able to do 1 rotation in 1 second, it would cause the final gear to rotate faster than the speed of light, meaning it would take infinite energy to accomplish.

[aritgirlfoamflinging]

Ot also gets harder to spin as you gear it up, due to a high amount of friction between the interconnected teeth

[maxcraig]

One trick is to make the small gear slightly thicker (2-4mm) than the large gear and then the large gears don’t grid against each other.
