Spline Dimensions Pdf 2021 | Din 5480

DIN 5480 is the German standard for involute splines with a 30° pressure angle, widely used in the automotive, hydraulic, and aerospace industries. Unlike many other standards, DIN 5480 is based on reference diameters that are independent of the module, allowing for easy integration with standard bearing sizes. Key Components of DIN 5480

Common Mistakes When Using DIN 5480 PDFs

  1. Confusing major/minor diameters: Unlike ANSI splines where the minor diameter centers, DIN 5480 centers on the flanks. The major diameter has a deliberate clearance gap.
  2. Using the wrong pressure angle: Always check the PDF’s header. Some older tables include 37.5° data. Mixing a 30° shaft with a 37.5° hub will destroy both.
  3. Ignoring the "W" vs "Z" designation: The PDF provides separate columns for internal (W) and external (Z) dimensions. Using the external shaft data for a hub cut-out will result in a loose fit.
  4. Outdated standards: DIN 5480 was revised in 2005 to align with ISO 4156. If your PDF is from 1985, the tolerance classes (e.g., H/h) have changed.

Centering: Primarily flank-centered, meaning the teeth transmit torque while simultaneously centering the shaft and hub. din 5480 spline dimensions pdf
