GEARINATOR
GENERAL

Tools across the workshop

  • Animated preview with playback controls, zoom, and pan
  • Drag and numeric shape editing with adjustable neighbour influence in shape-based generators
  • Save and reopen projects with generated tooth profiles
  • Tooth generation with progress, cancellation, and validation feedback
  • SVG and STL export with adjustable clearance for external pairs, fixed rings, racks, and circular planetary gears
  • Thickness, bore, and chamfer settings for supported exports; optional alignment marks for pairs, rings, and racks
  • Optional STL base generation with integrated shafts for external gear pairs

EXTERNAL

Noncircular gear pairs

  • Editable driver shape with a matching rolling gear
  • Mirror and rotational symmetry, plus an ellipse preset
  • Formula input: define radius or instantaneous ratio as a function of angle, with live gear and curve previews
  • Edit the instantaneous ratio curve and overall turn ratio
  • Scale shaft spacing while preserving shape proportions
  • Experimental concavity and freeform editing

INTERNAL

Fixed-ring gears

  • A shaped planet that orbits and spins inside a stationary ring
  • Edit the planet outline, symmetry, and orbit radius
  • Adjust the rolling ratio and its curve through the cycle
  • Separate planet and ring output with ring-wall checks

LINEAR

Straight racks

  • Noncircular driver paired with a finite straight rack
  • Set rack length by millimetres or driver revolutions
  • Adjust rack backing thickness and the linear-travel curve
  • Edit vertical driver bounce without changing its pitch shape
  • Playback reverses at the stroke ends; export driver and rack separately

CIRCULAR

Planetary gears

  • Search circular involute layouts with two to five planets
  • Set tooth-count ranges, module, and a centred or orbiting sun
  • Fixed-ring motion preview and sampled carrier-cycle checks
  • Straight or herringbone STL teeth with adjustable helix angle
  • Separate parts or an assembled print-in-place trial; no carrier or shafts generated

NONCIRCULAR

Noncircular planetary gears

  • Choose the sun or planets as the editable shape
  • Rotational symmetry with evenly spaced planets inside a fixed ring
  • Search compatible layouts with two to twelve planets
  • Sun-to-carrier speed graph and coupled tooth generation
  • Layout and motion studies; SVG/STL export is not yet available

SPHERICAL

Gearsphere

  • Circular ratio presets and noncircular three-lobed designs
  • Compatible tooth-count suggestions for circular pairs
  • 2D gear editing and an orbitable 3D centre-block view
  • Adjust centre size, face proportions, and gear alignment; fit gears to faces
  • Projection studies; spherical SVG/STL export is not yet available
