: Use 7H/7p or 9H/9v . Used for permanent, high-torque bonds. 📄 Verified Resources
DIN 5480 specifies tolerance classes that define the fit between the internal and external spline.
Primarily flank-centred , where the tooth flanks handle both driving and centring functions. Diameter centring (internal or external) is allowed in exceptional cases. Standard Designation Breakdown
7H/7e or 8H/8f (Good for precision and high-load torque). Clearance Fit: 9H/9e (Good for easy assembly). din 5480 spline dimensions pdf verified
. The number (8) is the tolerance class; the letter (f) is the deviation series. 2. Basic Dimensional Formulas For a standard 30° pressure angle
Denoted by uppercase letters (e.g., 9H , 7H ).
Legitimate PDFs have a red "DIN" logo and state "ICS 21.120.30" (the international classification code for splines). : Use 7H/7p or 9H/9v
The DIN 5480 series is the German national standard for involute spline connections. Unlike the ISO standard (ISO 4156), which is based on a series of modules, DIN 5480 is unique because its spline dimensions are based on a series of stepped "reference diameters" that are independent of the module.
Understanding the intricacies of DIN 5480 is essential for professional mechanical design. By using verified data, such as those available in the referenced PDFs, you can ensure your spline connections meet the high standards of performance and reliability required in modern machinery. Always refer to the latest, officially released standards for final design verification.
