Gear Generator

This gear generator computes standard spur gear geometry from a compact input set, enabling engineers, students, and CAD operators to rapidly iterate designs. It requires module m, teeth count z, and pressure angle phi as mandatory inputs and supports optional parameters for addendum, dedendum, clearance, bore diameter, and gear width. The output includes numeric parameters and a geometry summary suitable for CAD import, plus a visual representation of the gear mesh. It validates inputs and returns domain-safe messages when data is out of range or incomplete.\n\nConceptually, the tool applies involute gear formulas: pitch diameter d = m*z; outer diameter do = d + 2*m; base circle db = d*cos(phi); tooth thickness at pitch circle tp = (pi*m)/2; addendum a = m; dedendum b = 1.157*m; and overall depth h = a + b. Derived quantities are reported with units in millimeters and can be exported as CSV or JSON. Advanced features include optional placeholders for fillet radii and helix angle for future gear types. The design favors deterministic results and consistent data schemas for downstream CAD and simulation workflows.\n\nUse cases span design studies, course demonstrations, production data preparation, and verification tasks. The unique value lies in parametric, repeatable data generation, immediate visualization, and straightforward export to common formats.
