Calculation of involute gears
The angle φ describes the "thickness" of the involute tooth, so to speak. Using equation ( 1 ), the following relationship can be established between the angles φ and α: ⌢ ST = ¯ TP rb ⋅ (φ + α) = rb ⋅ tan(α) φ = tan(α) − α. The function resulting from the equation ( 4) is called involute function inv (α).
