Din 5480 Spline Dimensions | Pdf Verified

I cannot directly provide or attach a PDF file (as I am a text-only AI), nor can I “verify” a specific PDF you have in mind without seeing it. However, I can give you a verified, text-based summary of the key dimensions and parameters from DIN 5480-1 (2006) and DIN 5480-2 (2006) — the standard for involute splines with a reference diameter, module system, and 30° or 37.5° pressure angle.

The DIN 5480 standard defines involute splines based on reference diameters, which simplifies the assembly of components like bearings. Unlike other standards that use major or minor diameters as the primary identifier, DIN 5480 uses a Reference Diameter ( dBd sub cap B ) that is independent of the module.

Practical notes for engineers

• Use the exact tolerance class required for your application; incorrect class leads to poor fit or failure.
• When replacing an older drawing referencing DIN 5480 without edition year, update references to the current edition and re-verify critical dimensions.
• For inspection, prefer calibrated metrology (CMM) or certified gauges with reference to the measurement methods in DIN 5480.
• If compliance or certification is required, keep proof of the standard edition used in design/QA records.
