Gearinator
Gearinator is currently version 0.4 alpha and is a work in progress. It is a generator for non circular gears and non center planetary gears. Future features will include a gear sphere generator. Its free for non commercial usage, no ads, no trackers, no subscriptions.
Features of Gearinator (among others):
- Interactive shape editing — Drag handles or enter precise values to adjust your design.
- Editable ratio curve — Reshape gears by changing their instantaneous speed relationship.
- Symmetry tools — Mirror symmetry, 3-, 4-, and 5-fold repetition, plus mirroring within each repeated segment.
- Freeform shapes and SVG import — Explore inward curves and custom outlines with adjustable scale and shaft placement.
- External and internal gear pairs — Design two meshing gears or a planet orbiting inside a fixed ring.
- Tooth generation — Generate teeth with adjustable tooth count and backlash, with local fitting and recovery for non-circular profiles.
- Animated previews and diagnostics — Inspect motion, view the ratio graph, and identify regions that may need adjustment.
- SVG and STL export — Export toothed gears or plain shapes, with configurable thickness, shaft bores, and export-only clearance. No need for any CAD programms. Export, load in to the slicer, and print.
- Finishing and assembly options — Add optional STL chamfers, alignment grooves at a chosen assembly angle, and a simple two-shaft base for external pairs.
- Assembly information reports — Export a companion TXT file containing dimensions, tooth counts, spacing, and relevant settings.
- Eccentric planetary generator — Search and preview fixed-ring assemblies with an offset sun and two to five planets in a separate window.
- Gearsphere preview — Explore compatible gear outlines projected onto a sphere in an interactive 3D visualization.
- Complete project files — Save settings, shapes, and compatible generated teeth, then continue working later.
- MCP server — AI assisted gear generation. Can handle all settings, sketching, exports/imports etc.
