Free Clock Gear Generator | Mechanical Wooden Clocks & Horology Trains

Design mechanical clock trains, wooden gear clocks, and kinetic sculptures. Mechanical horology requires high gear ratios (e.g. 60:1 for seconds-to-minutes, 12:1 for hours). GearDXF lets you design and simulate multi-stage clock trains with vintage spoke cutouts and 1:1 scale printable templates.

Key Features

• 1:1 physical scale PDF export formatted for standard paper and scroll saw wood cutting
• Vintage clock spoke patterns: classic 4-spoke, 5-spoke curved arms, and teardrop cutouts
• Automatic calculation of multi-stage clock train velocity ratios (60:1, 12:1, etc.)
• Generous root clearances and backlash settings to prevent wooden clockwork binding
• Interactive visual simulation to verify clock train rotation directions
• Free for horologists, woodworkers, and clock making enthusiasts

Frequently Asked Questions

How is a mechanical clock gear train calculated?

Clock gear trains use multiple compound stages where a large wheel drives a small pinion on the next arbor, multiplying speed from the mainspring or weight arbor up to the escapement wheel.

Why do wooden clock gears need more backlash than metal gears?

Wood expands and contracts across its grain with changes in seasonal humidity. Generous backlash (0.5mm - 1.0mm) ensures that wooden clock wheels never bind during humid summer months.

Can I design weight-driven or spring-driven clock gears?

Yes, you can configure driving wheels and small pinions with exact tooth counts to match your pendulum beat and gear ratio requirements.
