- Building a planetary gearbox is pretty simple, but design and printing one, this can be a bit painful. This video is more tutorial than my usual project videos. Planetary gearbox bodies are printed out with ABS but for gears, I did use PET-G.

I have watched over 100’s of channels and there is always stuff I dont like about them. Not the case with you, everything is perfect! Keep going!
Watched it again 😁. The explanation of the 3d modeling phase was superb 👌👌👌.
One suggestion about the clearance section: if instead of cutting the edge of the teeth, we scale both models down to 99.5 % or something similar, there is a chance that we get a more homogeneous clearance.
Very good explanation and walk through of the CAD. I wish more channels did this as clearly as you did.
Thanks mate! ;)
@@LetsPrintYT well done and thank you. When I free up I'm going to try printing one in resin.
Thanks a bunch for the video. Was dreading making gears but already have the design finished in a day.
WOW! Well done, it's amazing. Thank you
Thank you for the great video. Since you are using the first gear to cut you need to invert the backlash. So for first gear you create just put whatever you put for the other gears but negative. Hope this helps with future gears and tolerance!
Thanks for the video!
Just an idea: Double helical cutted gears usually won't be mountable in a planetary gearbox due to the design of the gears. With your design you get a workaround to assemble the gears, but it is more like a 'quick 'n' dirty' way. 3D printing is in fact the only way to get these gears placed within a planetary gearbox: You can print all the gears at their mounted position and don't have to assemble them. I know that this works since I saw the result of such an attempt. I'd love to see this as a future project!
Greetings from Germany and keep doin' whatcha doin' 👋
Love your videos and the sense for humour :D
This was a fantastic video! Thank you! I learned a lot more than just how to design planetary gears. It's nice to see someone talk about building tolerances and stuff!
Looks great!
Love the content, keep it up!
Beautiful! Thank you
Thanks a lot. This was very helpful for me.
Cool, thanks for posting
It's good work, but there is a lot still to improve:
1) Like GearDownForWhat, you're modelling your helical gears in the normal system. Change this to the radial system, and your pitch diameters will revert to being just PD = m*Z, like it is for a normal spur gear. This makes all your calculations easier.
2) The reason you're experiencing binding is that a normal gear has an addendum of 1*m and a dedendum of 1.25*m. When you're doing that combine-cut, essentially you're turning the addendum into the dedendum and vice versa. You have to compensate for this.
3) For the ring gear, enter a negative backlash in the gear generator. When you do the combine-cut this will result in a positive backlash, as required.
4) The main challenge I'm still facing is the planet carrier. I don't like the idea of 3D printed shafts rubbing on 3D printed gears directly. I think integrating small steel shafts with Igus bushings would do the trick, but I haven't actually done that yet. I don't think having a purely 3D printed carrier on a 3D printed gear will last very long at all.
5) When you're spinning your gearset I can clearly see the ring gear flopping around. Something's not right there.
I'm still working on my wifi tank, but I should have my own tutorial on ring gears and planetary gears up in a week or two. I already have some gear tutorials up, including one on helical gears that goes into the difference between the normal and radial systems.
Bro, you should do a tutorial to share your knowledge, we will apreciate
Planetary gear tutorial would be very useful indeed. It would be great if you could make it. Subscribed to not to miss it)
oh nice i wait on your video :D
I hope I'm not spamming too much, but my tutorial is out now: th-cam.com/video/71dn-eVdSmc/w-d-xo.html
@@antalz Thanks!)
The tutorial was a bit hard to follow because i'm new to Fusion 360, but i got it to work! Nice video
Smart Guy.... We must say "THANK YOU❗" 👍👍👍👍👍
Superb explanation bro. Keep it up. Good luck
Very nice video Bro! I like you content, i use fusion 360 too. My Printer is an Artillery Sidewinder x1
Very interesting thanks 👌
Do you think if the sun gear is printed in two halves (two seperate helical gears), the assembly would be easier?
You are perfect my friend. Congratulations 🥳
This is very special. It takes 3D printing to another level. Thanks Let's Print!
Great video! I want to see the flames from that PCB!
On another note. I was wondering how hard is it to make this design to fit a dial or tuning knob for fine adjustments in a radio receiver/transmitter?
Thanks for sharing this video.
Buen trabajo!!
To fix the tolerances you mention in the video just use horizontal expansion. In your case it would be horizontal expansion of -0.15 mm.
Thanks, Thi video was very usefull for my oun project
Hello, Cool channel !!! Thanks!
Realy nice🔥
Hey man ! I have watch some of your videos and i really like it ! (I even did the water pump😂, but there are so many leaks).I have also a 3d printer, but much less knwoledge about fusion 360. Can you please give tutoriel or smth like that ?
Thanks !!
Big help, Thank you
Amazing video
really cool
I wonder if you can print all the gears in place fully assembled and do a burn in with a low speed for the chevron or helical gears?
You should try to make a strain wave generator
woow, cool man
Really good video and I was a great model, but could you please do the same 1 to 1 with normal gears and not with double helical gear? that would really help me 😬😍👍🏼
Excellent use of "buddy".
love ur vids!
Thanks mate! ;)
@@LetsPrintYT np :)
советую, можно делать вставки способом конкрементации, ставя на паузу принтер и вставляя металлический элемент
Nice
Good explanation, ur slang is like a child just chilling
How did you secure the sun gear to the shaft of the motor?
This is essentially the gearing for an e-bike hub motor. Rather than adding an extrinsic motor to turn it, perhaps you could look at extending it like that.
Plugin exists for double helical gear! Makes your work a bit simple
Super!!!
Bro like it😀😃
can you make a gear design on how a excivator turns
Great video, the projecting part was very intresting, i appreciated the data writed on the image that way are clearer.
The speeching is also improving, whit a bit more practice you will be capable of been understood more clearly (an advice from a non english native speacker to another).
As i said, great video, follow this path.
(I'm a native English speaker) I thought he did a great job. Very easy to understand. All the phrasing came across as accurate. Sounds like he has spent a bit of time talking and hanging out with native English speakers.
@@Scott_C Sure i've heard Much much worse than that, i'm saing that whit a strong accent is often harder to get understood, than whit a more standard and "clean" pronunciation. Far from me to judge unintelligeble, i was just giving a simple tip that other and more capable friends gave to me. Still, good point
@@fragra7186 yeah man it's all a process. With practice we'll all get better at ...words. 😄 I'm even horrible at English and I've spoken it my entire life.
what is the reduction ratio please ?
Next time, try to find ESC from radio control cars, they are more powerful.
Hey, I'm in the progress of printing planetary gearsets myself. What backlash value do you use to make sure the gears don't bite? Or do you adjust addendum/dedendum?
EDIT: I noticed you use 0.1 for backlash but still if I use 0.2 on all my gears they keep biting.. (gear calculations are correct, it's purely a 3D printing material expansion issue)
EDIT2: disregard ... 11:10
can you share the slicer settings
Hi. Why wouldn’t you use abs for the gears? I’ve sent a broken gear off to a guy that will make me a new one but he says he’s going to make it out of abs as it’s stronger?
try to combine that in reverse to a roof top stove pipe wind heat turbine
This could help me for a little wind turbine?? Does the 775 motor Gearbox desing multiplicate rpm ?? So there technically will put the wind turbine transmisión of the blades???
If I want speed ration 3:1.
Can you he me with the design dxf formate?
please made a video on slurry type pumps
Nice good good
how is the motor shaft connected to the sun gear? Is it a press fit?
yes
love it! but what can you do with it?!
He never showed it off but the out-put shaft, the part that looked like a mouth sticking out the other side of the motor, would be attached to a drive shaft of something that needs added torque. Planetary gears multiply torque by the 100s-1K.
That would be a huge planetary gearbox, that delivers 1k of the originally applied torque in one step 😅
Chamfer the lower edges and you don't need the raft to avoid the elephant foot! The design is great but the 0,3mm tolerance is a quite too much!!
Check your printer settings and adjustment ! I'm sure it is possible to print in place without raft and lower tolerances.
Cura allows adjusting the first layer to prevent it now
Okay so if i understand correctly, i built a planetary gearbox using my anet A8 some days ago and then this video pops up and just destroys my self confidence 😂😂
Are 3D printed gears always so noisy when moving? Gears you can buy are normally very quite, do printed gears just need grease or..?
What software did you use to record Fusion? I know I have had issues with screen recording in the past where the menus don't show up
He used OBS
make two videos with the best programs, the first video with the free ones, and the second one with the money ones.
Where can this be used? Like you must have designed it by considering some application.
I need these machines toys, such like manual, automatic, cvt, and some different kinds of transmission, and gears. I do try to find at parts shop and Amazon but can’t find them. I am studying automotive at a community college in KS. I am looking them for educational purposes. Can some body tell me where I can buy them. Thanks
Since you're covering it you should throw some sort of lube grease inside.
About the elephant foot, you can just chamfer it out
what advantage is there from going from 3 planetary gears to 6
The load for each planetary gear and the connection between the gears will be lower so the planetary gearbox will be capable of more power. Though friction will be a little bit higher. Since mounting 3 planets on this gearbox is already not easy, this wouldn't be easier with 6 planets.
Make a another wind turbine that's uses gears and a better motor plz
Good video tho
what is the gear ratio ? I need one for real world application
I came here to ask the same 😂
💕👌👍
at the beginning of the video he says it is very important to use a ?????? when printing planetary gears. What was the word?
How much price
Nice! But as an educator you should have the difference between clearance and tolerance right. 😉
could be a language thing also. I always give non-english speakers a lot of tolerance cause they speak english a hell of a lot better than I can speak their language :P
Next is a Cycoil gear
If I'm not mistaken, this type of gear is being used in automatic transmission.
*Question*
What does this help in
Like what change it will make instead directly connecting the motor?
"A planetary gearbox is used to transfer the largest torque in the most compact form"
Thats vool
Planetary gears are good but what about worm gears
Not back-drivable, if this is something that is needed.
I am sorry I didn’t get that. You said use “arrat ” when printing gear. What is that?
he probably meant a raft. its a plate you are printing your actual model on.
@@peterenis5634 thanks. I am new at this and his accent didn’t help. I take pleasure in watching and learning from him. I know he spent hours on this stuff.
what is the use of this???
Hi
Hi
Tuna
Mater"
молодец! еще бы по Русскому коментарии были ;)
sorry did you say 3d printed sharingans
Where is Jupiter and Earth gear
Great stuff, but too fast for beginners..
How many Estonians watching this video?
Well, I'm almost ROFL every time he says teeth. Don't ask, you know why is that, eh? ;)
El papu
Is this just me, or you have strange accent? R u russian?
Hi! I am from Estonia. I know I have an accent like most Estonians who speak in English, we immediately recognize other Estonian who speaking English. ;)
@@LetsPrintYT cool, and thanks for answer :D
@@LetsPrintYT Sounded close enough to finns speaking english for obvious reasons :)
It is really hard to be an Estonian and speak fluent English :D You can check my accent on my channel, I am also pretty bad at that :D
I actually guessed Estonian, only because of Tommy Cash lol
I'm first plz give som value.....
Nice man! ;)
@@LetsPrintYT ;)
Too noisy
This is not how you design planetary gear. You mention nothing about relation of number of teeth number of sun gear and any other. There is a math involved in designing planetary gear. What you printed is in no use, its wobly and noisy. You mention nothing about force it carry over... so many things
I wanted to.... get into this.... But every project is so useless.... And the everything is oversized because of the weak plastic.... I dont know that you lack the skill or is it really this 3d printing stuff just bad?
i think you know nothing about 3d printer. i work every day with a couple of different printers and all make the same job at 0.1mm
