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. Keywords: planetary gear calculator, gear design, mechanical engineering, productivity, utilities, CAD export, robotics, high-efficiency transmission.

How to use:
1. Install and open the app, then create a new planetary gear design and choose your units and standard.
2. Enter your target ratio and basic inputs such as number of planets, module or diametral pitch, and an initial tooth count if known.
3. Tap Solve to get sun, planet, and ring tooth counts, center distance, and validity checks, then review the live schematic preview.
4. Refine constraints such as ratio range, minimum teeth, and allowable clearance, and adjust until warnings are cleared.
5. Save the project and export a calculation report or CSV for CAD and collaboration, or duplicate it as a template for the next design.
