Tutorial: How to Model an Eccentrically Cycloidal (EC) Drive in Blender

While most gear mechanisms are decades and even centuries old, the Eccentrically Cycloidal gear drive is so new the ink is still not dry on its patents. This video is published with the explicit permission of the patent holder.
This futuristically-looking mechanism is very efficient and extremely compact. The gear pair shown here has the gear ratio of 1:9, an almost impossible feat for a traditional involute gear pair.
For more info on EC gears, their technical characteristics, and patents, see www.ec-gearing.com.

amazing!!
im making a solidworks version :")

[@websonic1000]

FINISHED SOLIDWORKS VERSION? :)

Waiting for Solidworks version

Some say Blender isn't good at CAD modelling.
This video proves otherwise.

Designing isn't the problem, manufacturing is. Make a gear hob for it and it'll be everywhere in 3 years.

"This video is published with the explicit permission of the patent holder."
Why did you need their permission? Also, what motivates O.T. Vinta's AMAZING work when creating your website and all these very beautiful videos?

the circumference of the small pin is pi*d = 3.14*20 = 62.8
the length of the big gear is approx. 304.04
it's a 9:1 ratio, 62.8 * 9 = 565.2 > 304.04
that means there's sliding friction?

[@OTVinta3d]

There is no slippage. The pinion is eccentric, and therefore the ratio of reference lengths may not equal the gear ratio.

Thanks

[@MistressKuroko]

Quick someone make an eccentric cycloid planetary gear system! I'm too CAD. challenged 😞

[@TonyRios]

I made one

[@PersivanA]

@@TonyRios can i ask you for model?

[@marcelpopescu8754]

VĂ SALUT CU RESPECT.
O INTREBARE VĂ ROG.
CARE MODEL DE TRANSMISIE,
LA CARE UNA DIN CELE DOUĂ PIESE, DACĂ E ÎN CĂDERE LIBERĂ,
VA PUNE IN MISCARE CONTINUĂ , PIESA PE CARE CADE ?
MULTUMESC FOARTE MULT.

How to calc ratio in calculator?

[@bvbbegun8576]

cool

[@janeas2008]

what,s the max input speed and also max output torque?

[@serglinux7928]

Please help to do this in blender 2.9

[@rusticagenerica]

Not interested in 3.0?
