Volex Labs / Forge / V-belt pulley generator — text to CAD.

V-belt pulley generator — text to CAD.

Describe the pulley — V-belt section (A/B/SPZ/SPA…), pitch diameter, number of grooves, bore and hub — and Volex Forge cuts the groove profile to the belt standard and returns a manufacturable STEP, STL or DXF.

No groove-angle tables, no CAD seat. The groove section and diameter are generated to the belt standard and checked before download, so the belt sits at the right depth and grips.
