Internal Gear Generator
Generate internal ring gears and matching pinions for laser-cut mechanisms, CNC prototypes, 3D printing, gearbox models, and maker experiments.
What you can make
- Internal ring gears with matching pinions.
- Gearbox models, teaching aids, and compact mechanical layouts.
- Fabrication-ready parts for laser cutting, CNC routing, or 3D printing.
Export formats
- SVG for laser-cut internal gear and pinion layouts.
- DXF for CNC routing, CAD, and fabrication planning.
- STL for supported 3D printable internal gear settings.
How it works
- 1Choose internal gear mode and set ring teeth, pinion teeth, and module.
- 2Adjust bore, wall, mount holes, labels, and fabrication settings.
- 3Export SVG, DXF, or STL when the layout is valid for your project.
FAQ
What is an internal gear?
An internal gear has teeth on the inside of a ring, so a matching pinion can mesh inside the ring.
Can I create the matching pinion?
Yes. The internal gear generator is built around ring gear and pinion layouts.
Can I use it for CNC or laser cutting?
Yes. Export SVG or DXF files for 2D fabrication, then test the fit in your chosen material.
