Major dimensions for external spline (shaft):

| Dimension | Formula | |-----------|---------| | Pitch diameter | ( d = m \cdot z ) | | Base diameter | ( d_b = m \cdot z \cdot \cos \alpha ) | | Tip diameter (max) | ( d_a = m \cdot (z+2) ) | | Root diameter (min) | ( d_f = m \cdot (z-2.5) ) | din 5480 spline calculator excel

For internal spline (hub):

Tooth thickness / space width are defined via basic rack shift and tolerances (e.g., e‑a, f‑h). DIN 5480 describes involute splines with a 30° or 37
