Din 5480 Spline Calculator Excel [Fully Tested]

: Set up alerts if the inputted number of teeth combined with the module falls outside the standard DIN 5480 reference diameter limits.

Translate the standard mathematical equations into Excel syntax. Use the following exact cell configurations: =Cell_Module * Cell_Teeth Use code with caution. Base Diameter (

Hub Tip Diameter (da2)=m×z+2⋅x2⋅m+0.9⋅m[2.3.1]Hub Tip Diameter open paren d sub a 2 end-sub close paren equals m cross z plus 2 center dot x sub 2 center dot m plus 0.9 center dot m open bracket 2.3 .1 close bracket

d = m * z

Enter module, number of teeth, fit class (e.g., H/h, H/k), and reference diameter – get pitch diameter, root diameter, tip diameter, and space/land widths instantly.

⚠️ Always verify any downloaded calculator against a known example from the DIN 5480 standard or a verified supplier catalog (e.g., SDP/SI, GKN).

Designing and verifying involute splines according to the DIN 5480 standard requires precise calculations of diameters, tooth thicknesses, and tolerances. While manual calculation is prone to error, a custom Excel tool can streamline the process for mechanical engineers and designers.

The DIN 5480 standard defines involute splines based on a standardized 30° pressure angle . Unlike other standards, it uses reference diameters : Set up alerts if the inputted number

DIN 5480 describes , module series, and side fit. Key parameters:
