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. Don't trust every random download

| | Specification | |:---|:---| | Standard Series | DIN 5480 (replacing older DIN 5480-2 through DIN 5480-13) | | Tooth Profile | Involute splines | | Module Range (m) | 0.5 mm to 10 mm | | Number of Teeth (z) | 6 to 82 | | Pressure Angle (α) | 30° (Exclusively; 37.5° and 45° are covered by ISO 4156) | | Basis of the System | Reference Diameter (dB) , independent of the module |
Instead of a static PDF, many engineers use verified spline calculation software that embeds the DIN 5480 tables. Examples include:
