Nominal dimensions and data tables for specific module and diameter combinations.
Under load, the forces naturally center the shaft within the hub, ensuring high concentricity.
Here is a glimpse of how the dimensions are structured (example for Module 2): 20 mm Module: 2 Teeth (z): 9 Major Diameter: 22 mm Minor Diameter: 15.5 mm Reference Diameter: 30 mm Module: 2 Teeth (z): 14 Major Diameter: 32 mm Minor Diameter: 25.5 mm Conclusion din 5480 spline dimensions pdf
Understanding DIN 5480 Spline Dimensions The standard is a widely used German engineering specification for involute splines with a 30° pressure angle . Unlike other standards like ISO 4156, DIN 5480 focuses specifically on a reference diameter system to ensure fit and interchangeability between shafts and hubs. Core Specifications
Ensure your manufacturing partner has the correct module-cutters or broaches matching the specified module and pressure angle. Nominal dimensions and data tables for specific module
Unlike minor-diameter or major-diameter centering systems, DIN 5480 primarily relies on the flanks of the teeth to align the shaft and the hub. Reference Diameter (
) : Two pins are placed in opposite spaces; the distance between the inside of the pins is measured. The diameter of the measuring pin ( Decap D sub e ) is typically for most standard DIN 5480 calculations. Why Use DIN 5480 Over Other Standards? Unlike other standards like ISO 4156, DIN 5480
Dimensions are calculated using metric modules ( ) rather than diametral pitch.
To effectively use a DIN 5480 dimensions table, you must understand the relationship between the number of teeth ( ), the module ( ), and the diameters. Reference Diameter (
