50:1 Compound Planetary 3D Printable Gearbox 

These are the gears that I'm looking for. Thank you!

Wow, really nice work. I am also printing gears really often, maybe I miss but what do u use PLA or something else? Love u videos!!

Good gearbox and very well explained! Cheers mate!

How did you go about learning to make this? Thanks for the upload!

I really appreciate your hard work bro. Keep it up 👍👍👍👍👍👍

Thanks for a great gear! I've been told that you like to have the gears with prime numbers of tooth, or at least no common divider, to equalize the tooth wear.

This looks great. Have you tested the reverse play somehow?

you r the man! thanks for this masterpiece!

Hi. I also printed this gearbox in SLA method. It is pretty amazing. Tonight I am assembling it and test it. My project is an electric bike and I want to use your gearbox connected to a brushless outrunner motor wig belt drive. I will film all the steps and share. Once again thanks for the stp files. They are a good starting point in any products with gear reduction. Cheers!

Fantastic video, love it.

you could cast each individual gear in maybe iron or copper and then make a full sturdy load-proof gearbox :)

This is great... But what would change design wise if i want it to increase speed instead of reducing it?

my brain melted after this video

THAT WAS AMAZING!!!

can you do it on the other end like how fast will it go?

What's the highest ratio that can be driven by the low end?

How can I make it so that I can put a crank on it and rotate it so that the output is 50 rotations per crank, do you have a file for that? I'm not too good at 3D modeling! Thanks.

What's great about this type of gearbox is you can make them print in place.

Perfect. This is what I need. I know how to make serial production. But how about 1 to 3 pieces? Do you know someone who can manufacture it and sell it?

hi, could you please guide me how to build the gearbox of 320:1 in the smaller size?

You could make jig that helps to hold the planets and sun in perfect position while you clamp on the rings.

Great video, Thanks man

So does the sun gear on the 2nd stage at 21:45 stay there, and doesn't control anything, and is only there to keep the planet gears from bending inwards?

Can it be back driven?

can i have the details of ? i mean no. of teeth in sun gears and tooth size... its really required kindly help

What 3d printer are you using?

How is the ratio computed?

Very nice. U definetly like it complicated :)

Thank you for sharing your work, but how does the gear ratio 49:1 come out? Can you tell me about your calculation in detail?

Where can this gear box be purchased?

how did you calculate the ratio? from what I see one set is a 4:1 and the other is 4.8:1

Does this also work with 1:50 ratio?

Hello! to power these gears you need to attach a motor to one side of the gear. In this possition, the weight of the gear is always creating a unbalancing force on one side of the arm (or whatever the gear is driving...). Is it possible to build a gear like this that allows to insert the motor "inside" the gear axially to avoid torque creating by the motor weight on the joint ?

can you make one that can drive backwards? a 1:5 or 1:10 or what ever maximum ? People say its not possible to drive backwards for one turn of a motor to get 10 turns at the end of the box. But what if you have a planetary gear box driving the backwards side so that it is half what the backwards planetary box was. So you have a motor, then a 5:1 driving a 1:10, if having a 1:10 would not be able to be driven by just the motor.

What material did you use for the gears?

Hi, I'm trying to print and build this gearbox, but the issue I'm having is that the ring gear gaps seem to be stretched apart too far when the planet gears pass over them. This causes the turning of the sun gear to be jumpy. I printed the files from thingiverse using the exact wall thickness and infill settings you mention at the beginning of this video. Any ideas what I should do to fix this?

backlash... doesn't matter how tight you couple the gears, the gears wears their own backlashes out. that's with every gearing system.

can i have the robotic arm design i want to learn how the stepper motor in the joint causing the movement to whole robotic arm

A worm gear can easily do 60:1 reduction - far simpler. Also love the age of empires style music

ever watched an anime named ''clock planet'' , you ever tried making a city made of gears?

I made it, assembly is realy tricky, but works ok .

You sound like Bob from Bob and Doug.

great work but you forgot about greasing every little piece even grease the motor shaft might be a good idea to get - less noise - lass friction - more torque

could you send me the drawing file, i have to change something for my Project thanks

Okay, I'm confused, did you or did you not design this Gear set?

A moment of silence for that stepper motor

Hi, is it poasible to make forward move is 10:1 ratio but reverse is 50:1 ratio?

Please I want one Can you ?

I wonder if something like this would be able to handle the torque needed to bust bolts loose on a car..would be so nice not to use a breaker bar and just hit it with a drill, haaaa!

Hello, I'm loving your videos and learning a lot. I have a need for creating a 50:1 gearbox that can be powered by hand from the lower rotation end. Would your design here work or with the torque be too much? Message me on youtube and maybe we could exchange info and discuss my project.

whats the purpose of making this thing

Thanks for the video.. but could you PLEASE hold stuff STILL unless it needs to move? I'm getting car sick watching you shake them around to emphasize your narrative.

I like your stuff and all, but the free-play music on loop is really hard to sit through.

lol ur using the tiktok song from 3 years ago

And truly amazing what you created And I've been looking for something like that for a long time. The piece called small ring makes me mistaken, even if I try to fix it on tools3d.azurewebsites.net/ potresti caricare su thingiverse il blocco corretto ? ti ringrazzio tantissimo inoltre se utilizzo 2 anelli grandi il sistema funziona lo stesso ?

Actually THIS is a mixture between a strain wave gear and a planetary gear.

your background music is too loud and distracting

remove the annoying noise

Ur geting a lot of noize and woobling, you did not model tooth number proportions correctly. It should run smoothly.

What the fuck am I doing here... :-/

Video too long
