Compare this to the older (often found in hydraulics).

Contact occurs on either the outside diameter (major) or inside diameter (minor). For maximum reliability, it is strongly recommended to

(Number of Teeth): The total count of spline teeth on the circumference.

When verifying a PDF, the following five parameters must be cross-checked against a secondary source (e.g., DIN 5480-1:2006-03 official edition). (Number of Teeth): The total count of spline

db = dref * cos(α) Alpha (pressure angle) is typically 30° for DIN 5480 (rarely 37.5° or 45°). PDF trap: Some PDFs erroneously show 20° pressure angle – this is part of DIN 5480.

This is the most common shop-floor method to verify tooth thickness and space width.

DIN 5480 Spline Dimensions: A Comprehensive Technical Guide In mechanical engineering, involute splines transmit high torque while ensuring precise axial alignment. The German standard is the global benchmark for designing and manufacturing involute splines with a 30° pressure angle.
