We make a powerful robotic actuator based on a cycloidal gear made of metal laser-cut parts. At the end of the video we test it for maximum speed and torque.
The cycloidal wheel generator has beeen taken from:

I am very pleased that my work, after so many years, still helps create great things. Great invention. Share it ;)

@ruslanaldabergenov5320 4 месяца назад

Great job! Do not forget to lubricate the mechanics.

I was just trying to do something like this, nice work! Awesome to see what goes into making it from another perspective.

Great video. Thank you for sharing this.

LOL!! Nice work with laser cut. Simple but strong design. Please share more info

@lowen74s 5 месяцев назад

Good to see someone else doing interesting designs with flat laser cut parts (the offset crank) where machining isn't feasible or possible.

@Jim_One-wl4ke 2 месяца назад

thats an awesome design. Compact & strong. Useful as actuators 👍. Thanks for sharing ❤

love this design

My god!! This is a beast!!! 😁

Very nice! The cycloids look durable, but I think the mounting of the motor should be better. Only those 4 bolts on the housing keep everything in place. That would also help with positioning the motor for coaxiality. Great work, subscribed!

Excellent! Metal laser cut parts are indeed the best choice! Maybe expand the drive for more torque?!

It would be nice to see a backlash test: by the way, very nice project

@dhruvbose8294 2 месяца назад

You placed that actuator dangerously close to the laptop during testing lol

@TheCuriousOrbs Месяц назад

Woudnt want to destroy tat $100 laptop

9:42 20kg at this angle are not 20kg perpendicular to the output axis, so either you need to calculate the torque with a shorter distance between motor axis and mount point of the spring

Very nice, well done What is the ratio of the gearbox

@mred3867 7 месяцев назад

great work HOX Best i,ve seen yet,👍 did it have much back lash?

@HOXrobotics 6 месяцев назад

Thanks, it has a quite small backlash, but still noticeable. I would say less than one deegree.

8:43 백드라이브 가능한 구조네. 신기하다

@Jayjlow 9 месяцев назад

To improve accuracy, how about getting the holes cut slightly smaller, then using a reamer to ream out the holes to final dimensions? Also, using shoulder bolts instead of using all thread bolts?

@HOXrobotics 8 месяцев назад

Good suggestions, I will consider them in next builds, thanks!

@adolphtrudeau 9 месяцев назад

That is an awesome build and I think I understand cycloidal gears better now. Wouldn't the motor get hot in the box? Will the gearset need lubrication and lube separation from the motor?

@HOXrobotics 8 месяцев назад

There should be no friction, the cycloidal gears only touch the roller bearings, the eccentric shaft bearings and the output shaft bearings. But you are right, it would be good to put some solid lubrication. If motor gets hot I could open some slits, or even put a small fan

Hi this is Harvey from PCBWay, we really like your work and would love to do some collab with you!

@HOXrobotics 8 месяцев назад

It would be nice! my mail is hoxrobotics@gmail.com

@MrTomtebloss 9 месяцев назад

Fun project! but two things really grinds my gears. First of you used no lubrication at all, and secondly you use the heads of bolts as the transfer from the motor and the gearbox witch is a bold move to say the least.

Thanks for sharing this! But, normalize your audio in post!!! hard to hear you.

@demidrol5660 9 месяцев назад

PEEK 3d-printed assembly like this should be much less noisy

@HOXrobotics 8 месяцев назад

Probably, but the idea was to make and test a full-metal gear to see if it was feasible

@Taygetea 8 месяцев назад

you dont even need PEEK, some of the nylons would be sufficient, and also printable on a bambu x1c. 3dxtech has a MoS2 infused nylon that i like a lot and intend to do this with, called WearX.
