DIN 5480 is a German standard governing involute splines with a reference diameter, used extensively in automotive, aerospace, and heavy machinery applications for torque transmission. Unlike older standards (e.g., ANSI B92.1), DIN 5480 defines splines by a module series, reference diameter, and profile shift, making manual calculation tedious. A spreadsheet-based calculator in Microsoft Excel offers an accessible, transparent, and customizable solution for engineers.
