The FASTEST Fully 3D-Printed Mechanism I've Ever Made (and maybe the most dangerous...)

This mechanism uses a simple gear chain to achieve 1000+ rpm speeds in a fully 3D printed mechanism (no screws or additional hardware- just 3D Printed PLA). Using a 60 tooth gear meshed with a 20 tooth gear (3 to 1) attached to a 90 tooth gear meshed with a another 20 tooth gear (4.5 to 1), they multiply together to achieve a 13.5 to 1 total ratio. That means that the output spins 13.5 time for every 1 full turn of the crank.
I designed this mechanism as part of a fully 3D printable desk sculpture. It's still a work in progress, but I couldn't wait to show this thing in action!

Everyone always talks about torque everytime there's a video about these gear ratios, but I've never understood what they are and how they're related to the video.

[@SpadeNya]

@@JollibeenosHasYourCoordinates torque is a measurement of rotational force, think of it as spinning momentum. The more torque, the more you can move. However, gears change torque into speed. The bigger the output gear, the less speed it rotates with BUT that speed loss is turned into torque so the gear will be harder to stop, and will be able to move a gear with more load on it. Essentially, gears are spinning momentum levers. The bigger the diameter of the gear, the more it can turn speed to torque, the smaller the gear, the more it changes torque to speed. Do also try to remember that you can type the word into the search bar and have much more thorough explanation for free.

I mean the way I think about it is that, my body can recover from many instances of contact with acids, chemicals, sharp objects, etc. (Let me clarify by saying absolutely there are chemicals and machines that can permanently maim, dismember or kill you with minimal contact.) Even if concentrated acids at room temperature make contact with the skin on your hands you at least have 10-20 seconds (usually) to make it to a sink and wash it off. In this example, sharp plastic may cut you, but not take a finger off or something like that. All that said, your eyes absolutely cannot recover from significant trauma. Even a few mL of countless dilute chemicals and solvents, or any physical object (plastic, metal, wood, dust, etc.) can permanently scar your eyes. Vision is absolutely critical for living life as a human being because we are primarily visual creatures. My point isn’t that you shouldn’t care about protecting your hands and body (always wear proper PPE and be safe). It’s more so that you should be EXTRA CAREFUL about your eyes. (p.s. I know what you said was in jest but I just thought it was an interesting point you made so I wanted to throw my 2 cents.)

Techanically, its not spinning at 1000 rpm because we don't know how fast (in rpm) the hand crank is spinning. We could say it has a rotation ratio of 1:1000.

[@biekgiek]

This reminds me of a toy motorcycle from the 70's that had a dock with a crank handle that you used to spin up the rear wheel to pretty high rpm's. When you stopped cranking the toy bike would take off. Since the rear wheel was weighted and had a rubber tire, it would grip all kinds of surfaces, and would stay upright even after jumps and what not (gyroscopic stability). It was so much fun, and really painful if you happen to get your finger caught between the tire and the frame. Or one of your buddies spooled it up and then pressed the wheel against you. So many fond memories of so many dangerous toys.

[@bring6not12]

we used to make stuff like this in my robotics class, our gear reduction projects were cut short after someone made a 100:1 gear reduction and spun it with a motor so fast the final gear fell apart and sent the axle through 2 layers of wall into another classroom.

[@the-treviathan]

[@eclipseballad]

If experimenting with gear ratios doesn't lead you to indirectly making an anti-material round is it really science?

[@ninjaslayer9248]

Pretty cool ngl

[@thatguy7683]

Shouldve kept going to 1000:1 and used a faster motor

[@eliseb5918]

I'm the TA in 8th grade for a 7th grade robotics class and they were learning about gear reduction using worksheets but thank god they didn't actually print anything like that lmao

yes but then its all fun and games until the fan blade comes towards you while spinning at a thousand rpm

@@acrytala well you aren't going to spin it that fast it just needs to give you a little bit of wind so you stay cold and that's it
