| Parameter | Symbol | Description | Verification Checkpoint | | :--- | :--- | :--- | :--- | | | m | Basic tooth size (mm) | Must match standard series (e.g., 0.5, 0.6, 0.8, 1, 1.25, 1.5, 2...10) | | Reference Diameter | d(_B) | Ideal calculation diameter | Equals m * z (rounded to preferred numbers) | | Tip Diameter (Shaft) | d(_a) | Outer diameter of external spline | Verify against table for given module/z | | Root Diameter (Shaft) | d(_f) | Base of teeth | Critical for stress analysis | | Form Diameter | d(_Ff) | Start of involute profile | Must be below start of active profile | | Space Width (Internal) | e | Width of groove in hub | Tolerance dependent on class (e.g., 8f, 9H) | | Tooth Thickness (External) | s | Width of tooth on shaft | Measured over pins or via gear measurement | The Challenge: Finding a Free Verified DIN 5480 PDF Here is the reality check most online articles avoid: You cannot legally get a fully verified, complete DIN 5480 standard for free.
