Volex Labs / Forge / Shaft coupling generator — text to CAD.

Shaft coupling generator — text to CAD.

Describe the coupling — the two bore diameters, overall length, set-screw or clamp style — and Volex Forge returns a manufacturable shaft coupling as a STEP for machining or an STL for printing.

Bores are concentric and sized to your shafts, set-screw bosses land on flats, so the coupling grips and runs true without a redraw.

Frequently asked

Can the two ends have different bores?
Yes — each bore is a separate parameter, so a coupling between an 8 mm motor shaft and a 10 mm lead screw is one prompt away.
Clamp or set screw?
Either. Clamp couplings grip without marking the shaft; set-screw couplings are simpler. Name the one you want.
Will it stay balanced at speed?
The geometry is concentric and symmetric, so it runs true; for high RPM machine it in metal from the STEP.
