This is my cycloidal gearbox I built, and the python script I created to generate it!

Design Process

Version 1

This gearbox was a handcranked gearbox specifically meant to test the validity of the python cycloidal generator. It had a gear ratio of 1:9.

Version 2

This design was a micro cycloidal gearbox with a ratio of 1:9, meant to only take up the same footprint as a NEMA 17. Due to the tight tolerances needed for a small cycloidal drive and the lack of precision offered by 3D printing, this design did not work.

Version 3

This gearbox was the first working version to run on a NEMA 17. It has a larger footprint compared to Version 2 allowing greater tolerances and a fully functional design.

🛠️ The Python Script

This python script was based on the SolidWorks article Building a Cycloidal Drive with SOLIDWORKS .…
