If you download a PDF of DIN 5480 Part 1 (Generalities) or Part 2 (Dimensions), you will find tables structured by Nominal Diameter and Module

For high-fatigue applications, ensuring the root radius matches the cutting tool geometry is essential to eliminate stress concentrations. 8. Summary: Steps for Spline Design Using DIN 5480 When designing a connection using this standard:

Producing parts to DIN 5480 standards requires specialized machining setups and distinct verification tools to ensure compatibility. Production Methods: for all profiles

The DIN 5480 series is divided into several parts, each focusing on a specific aspect of spline design and manufacturing: Part Number Title/Focus Key Content DIN 5480-1 Principles Symbols, preferred series ( modules), and fit systems. DIN 5480-2 Nominal Dimensions Detailed tables for nominal and inspection dimensions. DIN 5480-15 Inspection Quality inspection guidelines for spline joints. DIN 5480-16

In mechanical engineering, transmitting high torque smoothly between rotating components requires robust connection mechanisms. Splined shafts and hubs are the industry standard for these demanding applications. Among the various global standards governing spline design, the German standard is one of the most widely adopted worldwide for involute splines.

Involute splines are critical mechanical components used to transmit high torque between shafts and bores while maintaining precise coaxial alignment. Among the various international standards governing spline geometry, is one of the most widely adopted frameworks in European and global mechanical engineering.
