Volex Labs / Forge / Chain sprocket generator — text to CAD.

Chain sprocket generator — text to CAD.

Describe the sprocket you need — chain pitch (ANSI #25–#80 or ISO 06B–16B), number of teeth, bore and hub — and Volex Forge builds the tooth form to the roller-chain standard and returns a manufacturable STEP, STL or DXF.

No tooth-form tables, no CAD seat. The profile is generated to the chain standard and checked before you download it, so the chain seats and runs true.

Frequently asked

Which chain standards are supported?
ANSI #25 to #80 and ISO 06B to 16B — give the chain designation or the pitch in the prompt and Forge sizes the teeth to it.
Is the tooth form correct for the chain?
Yes — the tooth profile and pitch-circle diameter are generated to the roller-chain standard, so the chain seats correctly around the sprocket.
What does a sprocket cost?
Forge is free to try; individual parts are from £2.99. You only pay when you download a file you want.
Which format should I use?
STEP for CAD and CNC, STL for 3D printing, DXF if you only need the 2D tooth profile for laser or waterjet.
