Generate an involute spur gear or a matching pair with profile shift, clearance/backlash settings, and live center-distance/ratio readouts. Preview animation, export the result as SVG, DXF, or a ZIP containing.
Use this as a gear geometry generator: pick module, tooth count, profile shift, pressure angle, and fidelity. Toggle gear pair to preview two gears meshing (external or internal) with live ratio and center-distance readouts.
Toggle the gear pair to animate two gears (external or internal mesh), read ratio and center-distance instantly, and export SVG/DXF or a flat ZIP bundle with both gears.
Reference geometry and engraved metadata are included in exports; profile shift is carried into labels and reference circles.
