Why choose GearGen.xyz

Speed

First spur pair in 10 minutes, not an hour in CAD.

DXF export

One-click DXF, optimized for CAD input.

Gear dimensions

Full gear dimensions in one report — updates as you design.

Trochoid roots

Hob-cut trochoid roots in every export — not the simplified teeth other generators draw.

Precise tooth control

Dial in your backlash and tooth thickness at the same time.

Profile shift

Design and manufacturing to keep your designs clear.

Span inspection

Reverse engineer and verify gear geometry quickly with the span measurement.

Share & embed

Share a link or embed a live gearset — free for collaboration.

Planetary geartrains

Sun, planet, and ring in one tool — try ratios without rebuilding CAD.

Time comparisons based on typical manual CAD, spreadsheet, and handbook workflows.

Functional Gear Design, Made Intuitive

Everything you need to move from a blank canvas to production-ready geometry, directly in your browser.

Phase 1

Design

  • The Fundamentals: Define your gear geometry with total control over module, pressure angle, profile shift, and backlash.
  • Custom Layouts: Build complex geartrains and planetary systems using an intuitive X,Y coordinate grid and angular positioning.
  • Reverse Engineering: Input known measurements to solve for missing parameters and recreate obsolete parts with ease.

Phase 2

Validate

  • Visualize: Animation controls with interactive play, pause, and reverse to visualize mesh interference and verify rotation.
  • Gear Data Reports: Access gear data blocks including diameters, tooth thicknesses, tolerances, and inspection measurements.
  • Part Numbers: Assign part numbers and custom descriptions to every gear in your gearset to stay organized.

Phase 3

Execute

  • Save: Save geartrains online and reopen the same assembly from any device without rebuilding your layouts.
  • Shareable Links: Generate shareable links to send your gear data for collaboration or create an iframe to embed in your website.
  • CAD Export: Export optimized DXF and SVG files to import into your CAD software. Start building your parts today.
