What makes cycloidal gearboxes so amazing? 

A cycloidal gear drive CAN be back driven. Yours was just not smooth enough to allow for the motion.

Awesome video! Excited to see it connected to a drill 🙌

Have you shared these files anywhere? I would love to print one myself!

Good video. You should combine this print with the World's biggest gear ratio... video and tweak it and see if you can spin it and how many gears it will work with

A oil control gear for a mustang looks very similar minus the strap on top etc… Coyooooooooooote baby!!

I wonder if a cycloidal engine would be possible? think like a rotary but using the action of the cycloidal interface as the engine rotor.

Using this with steel encased with oil at higher RPM: Handheld? Vibration monster with some heavy waddle with the rpm ramp-up. Fixed machine - Very nice aside from that it's a Friction monster regarding sliding-friction (where it sort of slides at the apexes pointing inward from the orange gear), if it's smooth it will work nice, but the sliding-friction will create a lot of heat. Dirt & Grime: since the apexes of the blue gear seems to "press" into the wells of the orange gear, dirt and grime could cause incremental damage which would seize the system very shortly after first detection of any irregularity. Using pristine and pure material and-of utmost exquisite part-precision and lubrication you can have a very small high torque gearbox that WILL in fact last a very long time. Yet still, after the first detection of any irregularity, you will have a failing system in no time. It's very delicate, but still if you want very nice things you need to be prepared to lose them easily. This also seems ridiculously easy to replace, lots of replacements won't be a hassle in most machines and devices, the cost for this even with the best of everything you can get will still cost significantly less if you desire keeping spares and have the will to replace them when needed so.

Thanks

Hello, did you share the cad files of the cycloid reducer in the video anywhere?

Is there a way to have your files to 3d print the drive? or can I buy one from you?. Thank you Antonio Domit

I think why people rather use planetary gears is because they don't create an unbalance.

I have a doubt, on my project i was using planetary gears to make a reduction of 64:1, but the high RPM and friction kept destroying the teeth. Would a cycloidal gearbox be a good option? Nice video btw

How do 3D printed Cycloidal gearboxes hold up to wear versus planetary? I want to start getting into designs involving motors and rotation, but I want to stick to one dominant gearbox strategy to start, I I prioritize ease of printing and reliability.

Strain wave next

Very simular to how an oil pump works in a vehicle.

Cycloidal drives CAN be back-driven, as long as you don't weld the output shaft in place.

tanks, i send my LIKE!!!, maybe can share the stl?, thanks

Looks like the inside to a ls engine oil pump

Any fusion downloadable files so kids can play with it?

friction between blue gear & white shaft??

I think this is very cool, however, there a very many drawbacks to cycloidal gearboxes with the biggest being manufacturing as well as vibrations. Do to all the rubbing that occurs they easily generate rough vibrations which is unacceptable in profession machinery. When it comes to manufacturing the process to mass produce gearboxes. A standard gear is very easy to manufacture, however a cycloidal gear requires a milling machine. This is okay for special cases but their is a reason why you rarely see cycloidal gear drives mass produced. (Also cycloidal gearboxes can be back driven)

It would be cool to see a backdriveable/reversible cycloidal gearbox. And am I crazy or does this look like it could be turned into an electric motor?

Wondering whether the German engineer Herr Doktor Felix Wankel drew upon that principle to design his now legendary rotary internal combustion engine cannot be helped.

>it can't be back driven Nah, it's just the 1:8 ratio, pal. Add a handle, lube the thing up and try just a bit harder.

Seems like a ton of friction though 🤔

To those who can’t afford Fusion 360

Если он сделал ручку чтобы вращать, зачем вращал рукой? Бесит.

SO much friction in this design

Bean

The fact that thing is over complicated and frail, when one could achieve the same result with a much more simple geneva mechanism....

I love your contents, can I get a comment heart?
