Helical Gear Generator

Generate a steel helical gear for a gear pump. (z=20, m_n=2, β=15°)

Whether you are using FreeCAD, Fusion 360, or a dedicated generator like GearTeq, the workflow remains consistent. helical gear generator

Input: m_n, z, beta, alpha_n, b, hand Compute: mt, alpha_t, d, db, lead For each tooth k = 0..z-1: Generate involute points in transverse plane (x, y) Rotate by k * (360/z) degrees Extrude along Z with helix angle beta (Optionally) apply profile shift End Output: STL or STEP file Generate a steel helical gear for a gear pump

Involute parametric equation (transverse plane): [ x = r_b (\cos \theta + \theta \sin \theta) ] [ y = r_b (\sin \theta - \theta \cos \theta) ] where ( \theta = \textinv(\alpha) = \tan\alpha - \alpha ) β=15°) Whether you are using FreeCAD
