Show HN: I'm a 15 Year Old Wannabe Engineer, This Is a Cycloidal Gearbox I Built
A 15-year-old aspiring engineer has created a working cycloidal gearbox, sharing the Python script used to generate its design. This micro-sized gearbox, with a 1:9 ratio, aimed to fit within the same space as a NEMA 17 motor. Despite the tight tolerances required for such a small gearbox and the limitations of 3D printing, this design was the first to run successfully on a NEMA 17 motor.
The design, based on a SolidWorks article, used two main parametric equations to create its structure. Version 3, the final version, includes modifications for reduced friction, higher efficiency, and increased torque output. The CAD files for this version are available for download.
