The is the global benchmark for designing flank-centered involute splines. Unlike other gear and spline standards that anchor calculations to the major or minor diameters, DIN 5480 determines all geometry using a standardized reference diameter ( dBd sub cap B

The standard is built on several key principles that any accurate calculator must adhere to:

DIN 5480 is unique because it uses specific profile shifts to maintain constant reference diameters. Your Excel sheet must calculate the profile shift coefficient (
