DIN 5480 utilizes a comprehensive tolerance system to control the backlash (clearance) between the shaft and the hub.
Usually designated with uppercase letters (e.g., 9H, 8H).
The standard is designed for torque transmission and centering between hubs and shafts, primarily in the automotive and hydraulic industries. Its core principles include:
DIN 5480 is a German standard developed by the Deutsches Institut für Normung (German Institute for Standardization). It specifies the features, geometry, calculations, and tolerances for and reference diameters based on modules. Din 5480 Pdf
DIN 5480 is a German standard published by the Deutsches Institut für Normung (DIN). It specifies the geometry, dimensions, tolerances, and gauging practices for involute splines based on module pitches.
DIN 5480 defines several quality classes, which are designated by the letters A, B, C, and D. The quality classes differ in their dimensional tolerances and testing requirements.
Are you designing the or the hub (internal) ? DIN 5480 utilizes a comprehensive tolerance system to
Under load, the forces naturally center the shaft inside the hub, minimizing vibration and runout.
DIN 5480 is distinct from other international standards such as ISO 4156 or ANSI B92.2M. Key characteristics include: Pressure Angle : Fixed at 30°. Interchangeability : Splines designed under DIN 5480 are
The root of the tooth space can be flat or rounded (fillet), depending on fatigue strength requirements. Structure of the DIN 5480 Standard Series Its core principles include: DIN 5480 is a
You can find the DIN 5480 standard through authorized technical document providers:
The standard officially replaced older spline standards in the 1980s and has since been harmonized with international standards like ISO 4156 (though specific differences remain).
The is more than just a file—it is the engineering blueprint for durable, high-torque power transmission. While the temptation to grab a free, unverified copy from a forum is high, the risk of scrapped parts and machine failure is far greater.
