An inverse solver for a Split-ring planetary gear set: start from your overall ratio, tooth-count ranges, and extra constraints. It finds matching integer teeth, lets you visualize the set with animation, tune reducer options, and export SVG/DXF (or a full bundle). Have fun.
Use it as a planetary gear ratio calculator / planetary gearbox ratio calculator for split-ring (compound) epicyclic sets, with SVG/DXF export.
Acts as an epicyclic gear calculator and planetary gear simulator: validate collisions, GCD rule, and hunting tooth while iterating integer tooth counts.
