Industrial ANSI 40 · 15/45, ISO 14 splines
A 3 : 1 conveyor reduction on straight-sided splined shafts, each retaining ring flush in a counterbore.

Stock-style: Type B hubs, keyed bores, two set screws each.
Using the CheapCAD Tools connector, design a two-sprocket drive in Sprocket Designer on ANSI 35 roller chain, about 300 mm between centres. Sprocket 1: 13 teeth, a sprocket; a 12 mm bore; a keyway 4 mm wide and 1.8 mm deep; a hub on one side, 26 mm across and 16 mm long; 2 M4 set screws. Sprocket 2: 26 teeth, a sprocket; a 16 mm bore; a keyway 5 mm wide and 2.3 mm deep; a hub on one side, 32 mm across and 18 mm long; 2 M5 set screws. Check the design, apply any Auto-fix it suggests, then export both sprockets as STL and give me the download link.
Paste it into Claude, ChatGPT or any AI app with the CheapCAD Tools connector, and it designs this drive with you, checks it and hands you the files. How to connect your AI.
The link opens both sprockets and the chain in the Sprocket Designer's 3D Mode. Change the teeth, bore, hub or spokes, then download STL, STEP, DXF or SVG. Strength figures are the app's plane-stress check of each sprocket in the material it names; SF is the safety factor.
