Customizable Helical Gear - 40 Tooth, 3.0in Pitch diameter

40 Tooth Right hand Helical Gear

3.0in pitch diameter

1.5in face width

20deg pressure angle

20deg helix angle, right hand

0.25in bore

Tired of spending time in Fusion just to change a gear's tooth count, bore size, or helix angle? Or searching vendor websites hoping they stock the hand and face width you need? I built a browser-based text-to-CAD gear generator that uses natural language prompts to create precise, parametric B-Rep/STEP and STL files using CadQuery and Python.

This is a 40 tooth, 3.0in pitch diameter helical gear with a 1.5in face width and a .25in bore. The angled teeth engage gradually instead of all at once, so it runs quieter and smoother than a spur gear of the same size, and the wide face carries a lot more load. Meshes with a matching opposite-hand gear on parallel shafts.
