The DIN 5480 standard defines the principles for splined connections with involute flanks based on reference diameters. Revised in 2006, the current standard consolidates sixteen previous parts into four core sections to simplify technical specifications. Core Principles of DIN 5480
DIN 5480, Involute splines based on reference diameters, differs from other spline standards (e.g., ANSI B92.1, ISO 4156) by using a reference diameter system rather than a fixed module or pitch. This approach allows for greater flexibility in shaft design but increases the risk of misinterpretation when relying solely on scanned or non-verified PDFs.
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.

Internal splines (hubs) are defined by space width (E). External splines (shafts) are defined by tooth thickness (s). A verification check: For a zero-backlash fit, E_min = s_max.
A verified PDF of this standard provides the specific data required to manufacture and inspect splined shafts and hubs. The core technical data includes:
