I am building a 6-axis robot arm and in this video you can see the manufacturing of one of the cycloidal reducers of the robot. Specifically, it is for the second axis.
You can see it in more detail in the video "Cycloidal reducer 1 : 19 Robot arm joint": • Cycloidal reducer 1:19...
In the following videos I will be uploading the diferent phases of the manufacturing of the robot arm.

@aminsaba7693 3 года назад

Hello again, I'd like to thank you for your guidance on my previous comment. I am still working on my Cycloid Reducer and I am having trouble with finding the suitable material and more technical information such as surface treatment for disk and manufacturing methods. I would really appreciate it if you could help me out or mention any hints so I can continue working on my project. Regards, Amin

How thrilling to watch! REALLY cool.

@aminsaba7693 3 года назад

Hi there, could you please help me out with designing a cycloidal gear? how can I figure out the PCD of the holes on the disk? can you suggest any references for finding the answer? Thank you for the helpful video!

@MRBEngineering 3 года назад

Sure, have a look at this video! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SWIx3GgqrAg.html I hope it helps you!

@TheLordbruh 2 года назад

congratulations!!! very impressive, why did you choose a cycloidal reducer instead of a planetary?

@RiderRickMaker 5 лет назад

This is absolutely fantastic! Since I can't manufacture involute gears I was thinking getting into this approach to add a 4th and (eventually) a 5th axis, I only have a question, are you using angular contact bearings? If you can, can you be specific regarding them? Thank you for this awesome video!

@MRBEngineering 5 лет назад

Thank you for your comment. I use radial ball bearings, so, this cycloidal drive is not appropiate for high axial loads. You're wellcome!

@gamerepair2020 2 года назад

Great job, looks like it was a lot of work to make that. I wish you would have put a 30-lb weight at the end so I can see if it can lift it or not.

@kantin67 2 года назад

That's a nice piece. I will soon make a fourth axis tombstone and the cycloidal reducer seems to me to be a good solution, have you measured the backlash of yours? thank you

@MRBEngineering 4 года назад

Tanks! Not really, but it could be better. It have 6 arcmin aprox

@aliheydari6790 4 года назад

@@MRBEngineering 6 arcmin is so small. Nice job. Any comment on the machining tolerance? I assume the backlash is due to the tolerance, right?

Do You have cad files? Thanks for this. I am looking for a good reduction gearbox for my robot arm.

@mattybuilds2614 5 лет назад

Did you do any tests to see if there was a difference between using 1 or 2 bushings over the pins? my assumption would be that using two would reduce friction so that each gear could have its own busing to roll against but was just curious if you had.

@silva01430 11 месяцев назад

@sajivshah5502 4 года назад

this is super cool. Is the stepper driving this a worm? or a bevel gear?

Hi, how big is the advantage over plastic? Could you estimate how much more torque you'll get out of it?

@richardwatkins6725 4 года назад

nice work

@ankur261995 5 лет назад

why is the speed of the link fluctuating between 3:40 and 4:00? Is it due to torque ripple caused by cycloidal gearbox?

@MRBEngineering 5 лет назад

Yes, the video shows a test I did for the first time, and I did not assemble the cycloidal gear well and that is why it makes this fluctuation. Now the problem is fixed!

@mohammadalibahrami1253 2 года назад

@@MRBEngineering Nice job. I'm going to build a cycloidal reducer and read some papers about it. According to the papers, the torque ripple is intrinsic to these reducers. Could you please mention how you fixed the fluctuation problem? Thanks

Drive pins are too loose. Hard to achieve precise movement out of it

@wernerboden239 5 лет назад

Is there an advantage, compared to the harmonic drive ? Is it about handling higher torque or lower backlash ?

@YOUnoobGER 5 лет назад

Harmonic Drive are proprietary and very expensive. But they are better with nearly no backlash.

Here is some math: x = R * cos(t) + e * cos(N * t) y = R * sin(t) + e * sin(N * t) R = ring radius N = number of pins e = eccentricity t = 0...2pi Then inset that curve by the radius of the ring pins.
