Planetary Gear Calculator

Planetary Gear Calculator is a fast, accurate tool for designing and validating planetary gear sets. Built for mechanical engineers, product designers, and robotics makers, it turns target ratios and basic constraints into feasible, production-ready geometry in seconds. Get clear answers, reduce trial and error, and speed up gear design and documentation. Core features include an instant solver for ratio, tooth counts, and geometry with real-time feasibility checks; constraint-aware guidance to avoid undercut and interference while meeting standards; and visual previews with one-tap export of reports and data for CAD and team sharing. With unit conversion, templates, and multi-stage support, it fits classroom learning, prototyping, and professional gear design workflows.
