Clean design. Clear and instructive explanation. Evaluated the results of the work. Original Content. Material list included. 3D Model included. Perfect video honestly.

What a SPLENDID video showing such a brilliant design. I am a bit amazed at the accuracy you got from the 3D printer.

This mechanism was my master's work during studying process, but yours is the best.

This is an absolutely beautiful design! Keep up the outstanding work!

This video can really add value to the other old industrial applications . Great work👍

Your channel is just amazing!! This deserved a scara pic and place with computer vision detecting objects!

Excellent as usual! I never expect anything less from your videos.

Gorgeous design. And brilliant explanation.

1. You can draw parametric curve from 0 to 180 degrees, then connect it's start and end, extrude half of the cycloid, and then just mirror it and get full shape. 2. It's better to use SolidWorks variables. This way you can change cycloid's shape much easier. 3. Efficiency was measured incorrectly. Does this motor really produce rated torque? Input torque should have been measured before measuring output torque. And it's also interesting how much torque will this reducer handle before something breaks. :)

James Bruton used Cycloidal Drives in his most recent version of the robot dog. And I somehow doubt that it did not inspire you a little. It's worth checking out

that was quite beautiful. elegant mechanics.

Great job! Thanks for sharing with us !

I'm an electrical engineer brought here by a chance, however I do have certain appreciation of the mechanical engineering. I am able to judge that this video presents an extensive engineering effort, showing itself both overall and in the details. I wish I could work with you on my energy conversion related projects (quite a lot of mechanical engineering is required there), or that my mech. engineers could represent at least a half of your ability and attitude to the subject.

In the first seconds of the video I thought the scene was a 3d rendering, so clean it is !!! until I saw your hand grabbing the device. Nice video and valuable content !

Beautiful work :)

OMG Thank you so much for uploading this video Now I understand how to drive it

Absolutely My Respect 👍🏼‼️

Awesome project! one of the best i've ever seen , Thanks for sharing, I really enjoyed it.

Brilliant work and explanation!!!!

Wow! absolutely amazing project. Thanks for share your skills

neat ! great job explaining.

Great explanation

Amazing job, mate

Wow. Incredible.

Beautifully done project! A transparent cover would be cool for showing what’s happening inside and dust protection.

Respect man. it's good job.

It thought it was a digital model, then you touched it and started interacting with it my mind melted for a second

Impressive piece of ingenuity ! Well done !

Wow this is a superb video. Subscribed & liked. Thank you!

Great explanation and great video.

Beautiful!

Cool project!

Wow the Design.❤️🇱🇰

That is dang cool great video

nice work

Great video! I’m curious what efficiency did you calculate? In/Out Power efficiency?

It’s very cool!

A sumitomo gearbox is the first thing I thought of when i seen this!! Try tearing one of those down to replace bearings!!

Incredible

14:01 nice project. You try any brushless motor? What about vibration on the Cycloidal Drive? its not incresead?

About the shaft : when screwing pla parts together, I avoid using purely undersized holes : there will be a lot of friction wich will generate heat when screwing, risking to damage the part. a common option is to use threaded inserts, but they are expensive and not always usable (tiny space for a screw, for example) personally, for 3mm screws (just for reference, my engineering project uses non less than 41 m3 screws all holes made with the following method) : a 2.3-2.4mm hole in the 3d model, that hole is re-drilled with a 2.5mm bit (inner diameter of M3, M5 is 4.2, for reference) with a cordless drill at slow speed to avoid melting the PLA, the hole gets a perpendicular exit (through part hole / I had in the model an other hole perpendicular at the end of the screw's hole) to make an exit for the debris, lastly the hole is slowly hand-threaded with a M3 tap and tap holder with a 2 turns down, half turn up, movement, to limit friction and let debris go down to the exit. If the hole is deeper than 15mm, I firstly do a 10mm pass, remove the tap and clear debris with a straightened paperclip, to much debris will make a lot of friction, heating up the pla and ruining the thread, so go slowly. Uses and personal recommendations : Fixing a pcb : a m3, 6mm long thread is enough. Fixing plastic parts together : a 10-15mm long thread is enough

Awesome bro.

Loved your videos and subscribed to your channel. I have a question if you can help. I am trying to build a platform using stepper motor which is rectangle in shape. It's 20 inch long and 8 inch wide. want to be able to put weights on this platform and being able to rotate (horizontal). Any idea how would I do this with timing belt or other mechanism.

Great video on cycloidal drives ⚙

Very interesting video on how to make our own cycloid motor at home, thanks for sharing with us ! On a 3D printer, the horizontal hole extension option is always problematic. I have tested it on many parts on my calibrated X1 sidewinder printer under ideamaker and this is not very accurate and repeatable, the outer parts are ok but the hole diameters are often oblong and always vary from clone to clone. First price 3D printer are good for POC but not suitable for a precision DIY part that must last. I hope that one day "How to mechatronics" will build a mini EDM machine with wire/electrode and/or a sls printer to allow home user to make complex and precise shapes in metal. I am pretty sur that most of us will be happy to sponsort him in order to product this kind of tools in opensource.

Превосходно проделанная работа 👍🏻

Beautiful my friend ❤️👍😍✨

Very good

Greatly explained! And shown details are also very comprehensive. Is the output speed very uniform or did you recognize any unsteadyness. So you recommend these published formulas?

amazing! bro

Can you recommend one or a substitute that will last decades?

Can you pressurize it with hydraulic fluid….or compress gas

Great job!

I actually used your version with the 3mm shafts as it didn't cause failure and was preferably lighter.

Good video! Bravo, brate! :)

love it

Beautiful. By the way, what if the outer part is driven by a second motor. How does output speed changes?

very cool!

10:40 SPACERS!

Hey all, just FYI, the equation as copied and pasted into SW had some issues. I copy and pasted it directly into SW2022 and it came up with something that looked more like a flower than a gear. After watching a video on Stepbystep-robotics channel I was able to figure it out. He had done some intermediate calcs on a couple of the terms and then replaced those terms in the equation and removed the associated parentheses that are no longer needed. This solved the problem. Also, in SW you can use the equation editor to lay out your terms and then put the equation into the sketch using the terms with, with " around each term. This makes your disk editable without having to re-copy/paste the equation in.

Amazing work sir. Please also work on DIY QUADRAPED robot.

I Love this video.

Its such a informative video, can we increase the speed by using cycloidal gearbox by reversing it. Is there any limitations for it..?

Can you make a video on the 4 digit display module with TM1637 IC Please

Good explonation. does it work on high rpm 10-50 k rpm?

Excellent work and video ! Congrats One question if I may : what are the advantages & drawbacks of a cycloidal drive vs a strain wave gear (harmonic drive) ?

Excellent video.

Thanks for sharing. Thanks to the sponsor comlany made it easy for us to see your current project. I need to see again and put my questions later here. Can you name so e apication please. Thanks. PJ, Germany

Could you add a link to the paper with the equation pls?

Is it possible to put a third disk in to balance it even further like an inline 4 engine? I think there's still a longitudinal moment generated by the two disks not being on the same plane.

fantastic

In all videoes which softwere is used to open 3d model

would a polygram of constant width also work when making the cycloid gear?

is there a way to design it to have little to no vibration?

Would this be a good replacement for a Harmonic drive?

AvE has a great teardown of one of these amazing devices.

Great!

Hi, I do not have the HT7333 regulator What alternative regulator can I use?

Da li drzite kurs arduina?

very good animation

Thank you for your helpful video. I was wondering if you could help me out with 2 questions. How did you calculate the thickness of the disc and also how did you decide on the number of output holes on the disc ? Your video was a great inspiration, I hope to build my own version very soon. Thanks again!

Amazing

would this be fine with 3d carbon fiber nylon filament?

My cycloidal gears want to slip off of their central as the tolerance wasn't made too tight. What do you think I should do to remedy this situation? Should I reprint the gears with a tighter tollerance to force it on the bearing and reconstruct the eccentric shaft or should I just super glue the bearing to the gear on the inside? I wonder if they eventually just do this from wear over time too

one question: if you have 12 bushings and the plates have 11 notches, why is the ration 11:1 and not 12:1 ? each notch of the plates has to engage 12 times to get one revolution. or am i misthinking the case?

are these suitable for ebike motors?

Good explanation. Thank you! Who invented this cycloidal? crazy!!

these things love and i mean LOVE being submerged in lubricant oil !!! in huge tractors they are always full of lubricate oil and they basically never fail .... tractors put them on final drives becoz of there robustness ... only seals and oil leaks but the mechanism hardly fails

hmm if the rotor is contacting the stator from the outside and have more teeth than the stator, does the drive go in reverse direction ?

Great video. Can you tell me about the music in the video, thanks a lot.

wow your video is very nice. i was experimenting with @James Bruton cyclodial drive model. would love to try with yours when i have enough filament. what is next harmonic drive?

Gorgeous design, and thanks very much for sharing the design files! In your test, the output torque was limited by the little stepper motor: Do you have any idea what the maximum torque is that the drive is capable of before breaking? It looks like it should be very robust!

In the video in which you told how 555 timer IC works can you tell which software did you use to animate the video???

If you want the outer housing (outer part to turn) and the pins that are used as the output to be kept in place, can you still use pins for the outside or do you have to have another cycloid?

This is nice

Can you please upload a tutorial on how to make automatic water level controller using 555 timer ic with theory and explanation

I wish the xt and yt equations worked for me, my cad package says they are invalid...sad

Ото мені чудо,хвильовий редуктор.

At 6:04 you said you can determine the ring diameter pitch using the number of rollers and their diameter. How? What is the formula for that?
