reference diameter

DIN 5480 is a German standard (Deutsches Institut für Normung) titled "Involute splines based on reference diameters" . Unlike older standards (such as ANSI B92.1 or DIN 5462/5463), DIN 5480 uses a unique modular system based on a rather than a fixed pitch or diametral pitch.

  • Pressure angle: The pressure angle (α) is the angle between the tooth profile and the line of action. For DIN 5480 splines, the pressure angle is typically:
