You, sir, are a Fusion360 WIZARD! I've been trying to get the same in Fusion360 but I thought I'd be dependent on equation driven curves, so I shifted to Onshape for this one. Can't wait to get my hands on your design and to study the heck out of it on Monday! Thank you so much! ❤️

[@AaedMusa]

Thank you!

[@collenmaunganidze3531]

Thank you so much, Sir! This is the most useful video on cycloidal gearbox design. You are literally a god.

[@TheRealStructurer]

Very nice! Have seen some other tutorials that include programming to get this done. Very generous of you to share 👍🏻 Will give it a try!

[@schamannpedro]

Wow, this is so cool! I really love this type of things, a model that can be adapted to the necessities without have to model all again, it's simply amazing. You're a genius

[@lowan7073]

I don't usually comment on videos, but for this one I feel obligated haha THANK YOU sir, you helped a lot. I will use your files and parameters to learn more about gear reduction in general. Hope you read this. You should be proud of yourself. Thank you again.

Glad it helped!

This is great!! 😊

[@ShmeegleSon]

awesome thank you!

[@audricgaspar2368]

How did you determine the diameters, eccentricity and so on? are there any rules of thumb? Otherwise, very useful video, thank you for posting it!

[@AaedMusa]

Thanks. It's all just a bunch of sketches and formulas that work together to create the cycloid profile. I got the basic idea of this from the youtuber Levi Jansen. As far as rules of thumb, as long as the eccentricity isn't too low or too high everything should work fine. There are some more restrictions with the model but you can easily identify and modify them.

[@PaulGouldRobotics]

This is a great explanation for use in Fusion 360 and thank you for making it open source. Can you explain how you generated the equation and made it run in Fusion 360? Is it a script?

[@AaedMusa]

No it not a script. I have a bunch of sketches with points that trace out the cycloid. It then connects all the points and uses a circular pattern to create the the complete profile. I saw this on Levi Jansen's channel and decided to make it parametric. Here is his video. kzbin.info/www/bejne/oIKZfYR4e7-Lo7c

[@Shiqari145]

@@AaedMusa but how did you transfer all those points into one sketch? (How did you connect those points?)

[@Shiqari145]

i mean you draw a sketch for every point on that cykloid. All points are in the end on one sketch. But they have to be dependant? How did you do that?

[@AaedMusa]

@@Shiqari145correct each point is made separately and the transferred into one sketch. Fusion 360 has a projection tool which allows you to transfer multiple sketches into the same sketch. When doing this each point is still dependent to their original sketch so when the cycloid is changed, the tooth profile (the final sketch) is also changed because each point is changed. There are a bunch of constraints as well in the sketch to make sure things stay aligned when a parameter is changed.

@@AaedMusa you are a great help. Thank you. I never knew that there is a tool like that

[@hariharanramamurthy9946]

is there a way to simulate it before printing it? did you optimize sir(all the parameters for working)?

[@AaedMusa]

Yes, I added joints to the model so you can always simulate it and make sure the cycloidal are engaging correctly. And yes, all the parameters work.

10:1 reducer ？

[@AaedMusa]

Yes the example is a 10:1, but since its parametric it can be any reduction value.

Como eu gostaria de entender como fabricar este tipo de engreagem cycloidal, a aplicar este conceito para fazer as minhas próprias engrenagem para cremalheira algo com isto -> kzbin.info/www/bejne/r6SwfIuJatKMbLc
