Cycloidal gear box code for FreeCad
This workbench will provide a working model of a cycloidal drive that can be 3d printed. This was done as a workbench since all parts need to be mathematically correct in shape and size in order to work.
As well as the working model, parametric sketches of all the parts are provided. The sketches are provided as master sketches that can be referenced as needed in order to have the correct sizes and shapes. Things like adding bearings can be added as extras to these master sketches. In this way you can work out the gear parameters by working with the parts, and then modify as needed for your own designs.
See wikipedia for an explanation.
In development
- FreeCAD v0.20 or >

git clone git@github.com:iplayfast/CycloidGearBox.git - Start FreeCad
- Select cycloidalGearBox workspace from the Workbench dropdown menu
- Click on the cycloidalgearbox icon and it will create (the beginnings of it) with some default parameters.

After much effort, I'm happy to report that the math works! I've verified this by doing a 3d print of the default parameters, and another with different parameters. Both gearboxs are functional!
