Split Ring Planetary Gearbox Python Script Application
Split Ring Planetary Gearbox Python Script Application and Calculator
This is a collection of Python scripts for designing a Split Ring Planetary Gearbox.
This is a really simply python script that helps design split-ring planetary compound gearboxes. The _gui.py script runs a Tkinter gui that allows for easy use and exports your desired number of solutions to a .csv file

Helps generate planetary gear combinations:
- number of teeth for sun, planets, outer ring
- output gear ratio
- module/sizes
Only works with split-ring compound planetary gears that are driven via first stage sun gear and output through second/last stage's outer ring, AKA split-ring
