DIN 5480 is a German standard for splines, which are used to transmit rotational motion and torque between two shafts. The standard specifies the dimensions, tolerances, and testing requirements for splines. In this text, we will create an Excel calculator to verify the dimensions and tolerances of a DIN 5480 spline.
: Incorporates strength calculations (based on Niemann or DIN 6892) to warn if the transmitted torque exceeds the permissible surface pressure for the selected material. Summary of Key Excel Outputs

Ensure that when switching from a fit of "8f" to "9f," the dimensions change according to the standard's tolerance tables. Step-by-Step: Designing with the Calculator

Primary focus on flank centering , although diameter centering is permitted in specific applications.
Verification is the process that separates a potentially dangerous calculator from a professional engineering tool. It confirms that your calculator's outputs match the authoritative tables and formulas of the DIN 5480 standard.
Use Newton-Raphson iteration formulas in hidden cells or an Excel VBA macro to solve for the virtual pressure angle at the pin contact point.
Do you need to include calculation support for both ?
To build a verified Excel calculator, you must program the exact geometry calculations defined by the standard. Basic Geometry Matrix External Spline (Shaft) Formula Internal Spline (Hub) Formula Base Diameter Major Diameter Minor Diameter

Use these where refurbishment of pressure angle due to profile shift or clearance is needed.
If any test case fails, fix your inverse involute solver or tolerance lookup table.
