Wow I Didn't Know it's so EASY to Design Cycloidal Drives

Cycloidal drives are important mechanisms in the field of robotics. Their design has been top secret until now...

Check how you can easily design a function cycloidal drives that can create insane amount of torque to power your biggest robotics.

Check out written version of this guide here

That's actually one of the best, if not the best explainer on how cycloidal drives work.

[kurtnelle]

So much complexity and precision components. I'm glad you figured out the simpler version to this.

Now that's a worthy contribution to the DIY Robotics community, thank you so much.

[thePavuk]

Simple and Easy sounds as impropriate words in this case.

I want to thank you for sharing this knowledge with us, as you can see I am not the only one who wanted to have this knowledge more digestible. I once had a full-time engineer trying to make one and we couldn't do it. Thank you very much.

[PeachBologna]

I've been looking for something like this! Thanks for the great video!

[kalihban]

It would be interesting to see if you could laser cut or cnc the large gear piece, that might increase performance a bit.

[AbdulRahman-juwk]

The most simple and compact design I have seen by far.

[Harveyhasea]

Stunning easy explanation, thank you!

It's unbelivable. I was trying to find or build the cycloidal drvies for my robotic arm. But, this is the best cycloidal drvie ever i have seen. Perfect. Thank you for your kind explanation and free publishing

[MatterLabz]

Great job on the design and the explanation. Thank you for sharing!

[gennadysmirnov]

It's very simple and understandable, thank you

[alexkart]

you should add the second cycloidal disk 180 degree out-of-phase to eliminate vibration.

[andresmonagas]

The easiest and the best explanation of a cicloidal drive on the whole internet

[CatNolara]

Only the one axial bearing for the output won't be enough, you'll need a second ball or tapered roller bearing to account for radial and angular loads. Your design won't be able to stay on axis and have a lot of friction and deflection with radial and angular loads.

Beautiful gearbox

What's is the weights of the gearbox and Max output torque with 3d printed material

[DytiscusUA]

In plastic it all works, the plastic is deformed.
But when it’s in metal, the slightest inaccuracy, 0.01, will break the mechanism.

Hi techer, Thanks for your guide. I have question, in section 'Design the Cycloidal Disk' step 2, 31/49=0.632, but in your guide set value to 0.622, could you please tell me why ?

[aaronmarkstaller]

Nice. How do you design the convolution or gear for the pins to mesh all perfectly?

[fabiengarnier]

Great job, i will try to do the same!
