DIN 5480 differentiates profiles based on whether the spline is flat-root (standard) or fillet-root. For standard flat-root side-fit splines: External Splines (Shaft) = m * z + 0.9 * m Minor Diameter ( df1d f sub 1 ): = m * z - 1.2 * m Internal Splines (Hub) Major Diameter ( da2d a sub 2 ): = m * z + 1.2 * m Minor Diameter ( df2d f sub 2 ): = m * z - 0.9 * m 💻 Step-by-Step Excel Template Blueprint

The pitch diameter is the theoretical reference circle where the tooth thickness equals the space width. Formula: d=m×zFormula: d equals m cross z =Module * Teeth 2. Base Diameter (

A standard calculator must handle deviations to ensure the parts assemble correctly. DIN 5480 uses specific tolerance classes (like for internal hubs and 8f, 7h for external shafts) to define space allowances.
