These splines are preferred for heavy-duty components requiring and precise centering. In modern CAD environments like SOLIDWORKS or AutoCAD , these dimensions are used to generate accurate 3D models for machining and interference checking.

Power transmission manufacturers often publish extensive technical appendices. Looking up documentation from companies like KHK Gears or framo morat provides rich geometric tables.
standard defines the dimensions and tolerances for involute splines based on a reference diameter. Unlike many other spline standards that rely on major or minor diameters, DIN 5480 uses the reference diameter ( as the primary basis for its calculations. d2t1xqejof9utc.cloudfront.net Core Technical Specifications This public link is valid for 7 days
, the base diameter from which the involute curve is generated is calculated as:
The standard ensures that by selecting a standard module and reference diameter, manufacturing tools are standardized, reducing costs and lead times. 5. Summary Table (Conceptual Example) Can’t copy the link right now
Default configuration relies on flank-centering , meaning the torque-transmitting side faces of the teeth locate the mating parts coaxially. Minor/major diameter centering remains reserved for exceptional, highly specialized use-cases. Module Range ( ): Scaled systematically from Tooth Counts ( ): Spans a practical working inventory from teeth per profile. Decoding the Standard Designation Callout
The reference diameter allows for standardization with ball and roller bearings.
Indicates whether the component is external or internal. W stands for Welle (German for Shaft / External Spline). N stands for Nabe (German for Hub / Internal Spline). 120: The Reference Diameter ( ) in millimeters. 3: The Module ( ) , which determines the size of the teeth. 38: The Number of Teeth ( ) .
The standard is split into multiple parts. Part 1 covers general principles and basic geometry, while Part 15 covers the quality inspection and gauging data. Ensure your engineering data sheets cover the exact sub-part you require.
