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.
DIN 5480 Spline Dimensions: A Comprehensive Review din 5480 spline dimensions pdf verified
DIN 5480 specifies involute splines with tight geometric and tolerance rules for mating shafts and hubs. Official, authoritative dimension tables and tolerances are published in the DIN 5480 standard document (German Institute for Standardization). For engineering use, always obtain the official standard (DIN 5480: — year-specific edition) from a standards body or authorized distributor; freely circulating PDFs may be incomplete, outdated, or unauthorised.
