The module defines the tooth size:
[ m = \frac\textpitch diameterN ]
where ( N ) = number of teeth. DIN 5482 uses standard modules: 0.5, 0.75, 1.0, 1.25, 1.5, 2.0, 2.5 mm.

Since the standard is withdrawn, finding an official PDF can be difficult. Here are legitimate ways to access the data:

If you have a drawing or a file name like DIN 5482 W30x2x18, here is how to decode it: din 5482 spline standard file type pdf77

Example Calculation: If Ref Dia = 30mm and Module = 2: Number of Teeth ($z$) = $30 / 2 = 15$ teeth. (Note: DIN 5480 uses a slightly different notation involving fit classes like 7H or 6g, which makes deciphering old DIN 5482 drawings tricky).

In mechanical power transmission, splined shafts and hubs are essential for transmitting torque while allowing relative axial movement. Among the many national and international spline standards, DIN 5482 occupies a unique historical and technical position. Developed in Germany, this standard defines involute splines with a pressure angle of 30°, a low root stress concentration, and a modular tooth system tailored for automotive steering columns, pumps, and other compact drive systems. Although superseded in many applications by ISO 4156 and ANSI B92.1, DIN 5482 remains widely used in legacy designs and repair manuals. This essay explores the key characteristics, calculation methods, applications, and limitations of the DIN 5482 standard, demonstrating its enduring relevance in mechanical engineering. The module defines the tooth size: [ m

A 30° pressure angle offers a compromise between the 20° angle (better bending strength) and 45° angle (higher torque capacity). It reduces radial forces compared to 45° splines while maintaining a wider tooth base than 20° designs.
