Volex Labs / Forge / Worm gear generator — text to CAD.

Worm gear generator — text to CAD.

Describe the worm drive — module, number of starts, wheel teeth, lead angle and centre distance — and Volex Forge builds the worm and the matching worm wheel, returning manufacturable STEP or STL files.

No lead-angle or throat-radius maths, no CAD seat. The pair is generated to standard proportions and checked before download, so the worm and wheel mesh at the centre distance you asked for.

Frequently asked

Does it make both the worm and the wheel?
Yes — describe the drive and Forge generates the worm and the matching throated wheel as a pair, sized to the centre distance.
Can I set the reduction ratio?
Yes. The ratio is wheel teeth divided by worm starts — give either the ratio or the two numbers and Forge does the rest.
What does a worm drive cost?
Forge is free to try; individual parts are from £2.99 each. You only pay when you download a file you want.
Which format should I use?
STEP for CAD and CNC, STL for 3D printing. The helical worm geometry is 3D, so DXF is not used here.
