Gear Generator Fusion 360

The tool provides a parametric spur gear specification engine for Fusion 360 CAD workflows. It accepts a compact set of parameters—teeth, module, pressure angle, bore, and width—and yields a complete geometric specification suitable for CAD import or script-driven geometry creation. Target users include design engineers, CAD technicians, and educators needing repeatable, auditable gear definitions and fast iteration during design, prototyping, and teaching.
The core logic models involute spur gear geometry using metric module terminology, producing standard dimensions (d, da, db, p, t) and derived values (addendum, dedendum, clearance, and an approximate contact ratio). It supports optional overrides for addendum and dedendum and can export to STEP/IGES or a Fusion 360-friendly parameter bundle for downstream CAD workflows.
Outputs are validated against typical ranges (positive module, valid tooth count, reasonable pressure angle) and can be used to seed CAD assemblies, CAM calculations, or educational demonstrations. The system emphasizes auditable parameter sets, traceable derivations, and compatibility with common ISO/DIN gear relations, enabling engineers to reproduce designs across projects and teams.
Use cases include rapid iteration of spur gear sets in transmissions, gear trains for educational labs, and pre-flight data generation for manufacturing pipelines.
