Many CAD/CAM tools, such as SolidWorks or Fusion 360, have integrated DIN 5480 generators, but having the PDF ensures you can verify the output parameters.

Because involute teeth are curved, machinists cannot easily use standard calipers to measure tooth thickness. DIN 5480-15 specifies the "Measurement over Pins" (for shafts) or "Measurement between Pins" (for hubs). Two precision pins/balls of a specific diameter ( DMcap D sub cap M ) are placed in opposing tooth spaces.

Designated with lowercase letters (e.g., 9g , 8f , 7h ). Designated with lowercase letters (e

is the German standard for Involute Splines (spline connections). Unlike simple keyed shafts, splined shafts and hubs allow for the transmission of high torque loads. They are commonly used in:

I can generate the specific geometry values and pin measurements for your project. Share public link Part 2: Nominal diameters and profile modifications

One of the most important aspects outlined in the DIN 5480 standard is how the shaft and hub align with one another. The standard outlines three primary centering methods:

A typical drawing callout for a DIN 5480 spline looks like this:

Usually designated with uppercase letters (e.g., 9H, 8H).

Indicates whether it is a Shaft ( W for Welle ) or a Hub/Internal Spline ( N for Nabe ). 120: The nominal design diameter ( ) in millimeters. 3: The module ( ), which dictates the tooth size. 38: The total number of teeth ( 8f: The tolerance class and position (similar to ISO fits).
