Spur Gear

grabcad

In this tutorial, we demonstrate how to create spur gears using parametric equations and formulas. Six parameters are defined with their values: Number of teeth (N=25), Module (m=3.5), Pitch circle radius (Rp = m*N/2), Clearance circle radius (Rb = 0.94*Rp), Addendum circle radius (Ra = Rp+m), Dedendum circle radius (Rd = Rp-1.25*m), and Fillet radius (0.39*m). By adjusting these two values, you can easily modify gear size and module length. The Workbench used is Part Design, and commands employed include Formula toolbar, Pad, Pocket, and Circular pattern.
