Genius ! Whats the ratio of this Gearbox ? The ring isn't deformed : Is it necessary to made it in a flex part or could i made in one piece with the white part ?
Honestly, genius. Have you run this through any testing? What is the efficiency of this reduction? And how much of a torque increase do you get while using that Nema 17 stepper motor?
Thank you. The idea came to my mind when I figured that the elastic part of harmonic or belt driven gearboxes is what gives you precision. I don't like the inner mechanism and complexity of harmonic gearbox so I designed a simpler one. The problem with a elastic part is that you only have zero backlash at zero torque. I'm not sure about torque increase, you can stop the outer ring with your hand. The longer the teeth the lesser efficient in torque transmission but the lesser backlash. I'm thinking what could be the optimal teeth profile. I will try more teeth profiles then I will make a proper torque test.
@@urielalbertodiazreynoso6309 great work , i think less backlash is better than increasing torque because you can always stack 2 gearboxes with low backlash
hey i was looking at the github files and there arent any spefic files on this desighn, al thats there is some cyclodial desisghns as well as a planetry desighn if you could lead me to the harmonic desighn as shown that would be great thanks
In theory yes, but sadly in the practice no. The very high ratio and the poor tolerances of a cheap 3d printer make most of these gearboxes nonbackdrivable.
This is cool, i am looking for a high precision, silent and hight torque geat

It is about 1:n where n is the number of teeth. The ring teeth should be elastic similar to a belt, maybe can be stiffer, try with PETG

sorry, I will search for the file then I comment you back
@@urielalbertodiazreynoso6309 not a problem thank you for taking the time to look for it

Not cool!
thanks
