Understanding DIN 5480 Spline Dimensions The DIN 5480 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

The DIN 5480 series applies to splines within the following ranges: Module ( ): 0.5 to 10 Number of Teeth ( ): 6 to 82 Pressure Angle: Strictly 30° How to Read a DIN 5480 Designation

A typical spline callout looks like this: DIN 5480 W 120 x 3 x 38 x 8f. W (Welle): Denotes a Shaft (External spline). N (Nabe): Denotes a Hub (Internal spline). 120: The Reference Diameter. 3: The Module ( 38: The Number of Teeth ( 8f: The Tolerance Class (defining the fit). Key Dimensional Differences din 5480 spline dimensions pdf

One defining feature of DIN 5480 is its reliance on the Reference Diameter (

) rather than the pitch diameter used in many ANSI standards. This system allows for more consistent manufacturing of various tooth counts within a standard diameter envelope. Specification Pressure Angle Fit Type Side-fit (flank centered) Interchangeability Not interchangeable with ANSI B92.2M or ISO 4156 Material Commonality Often C45, 4140 steel, or 304 Stainless Resources for Dimensions Understanding DIN 5480 Spline Dimensions The DIN 5480

1. The Module ($m$)

The module is the ratio of the pitch diameter to the number of teeth. DIN 5480 typically prefers modules ranging from 0.5 to 10. Common modules include 1.0, 1.25, 1.5, 2.0, and 3.0. A higher module means larger, stronger teeth. DIN 5480 is available as a PDF from

Standards & documents

• DIN 5480 is available as a PDF from standards providers; it includes full tables of dimensions (module vs. number of teeth), tolerances, and example drawings.
• For manufacturing and inspection, consult the official DIN 5480 document for exact numeric tables and tolerancing schemes.

Applications

Common in automotive, gearboxes, coupling shafts, and heavy machinery where reliable torque transfer and precise axial location are required.
