Din 5480 Spline Dimensions Pdf 〈2025-2026〉

When you look at a DIN 5480 PDF chart, you will see columns of data. The most critical dimensions you need to verify are the tooth thickness and the major/minor diameters.

| Section | Description | |---------|-------------| | Basic formulas | Calculation of reference diameter, module, and profile shift | | Tooth geometry tables | Standardized combinations of module, teeth count, and diameters | | Tolerance classes | Fit classes for precise or general applications | | Inspection data | Over pin/ball measurements, span measurements over teeth | | Material allowances | Heat treatment and finishing allowances |

Before diving into dimensions, you must understand the naming convention. A typical designation on a drawing looks like this:

DIN 5480 – W 30 x 2 x 16 x 9g

Here is what each segment means:

In the world of mechanical engineering, power transmission relies on precision. When a designer needs to connect a shaft to a hub with high torque capacity and self-centering capabilities, splines are the go-to solution. Among the many global standards, DIN 5480 stands out as the premier German standard for involute splines.

If you have searched for "DIN 5480 spline dimensions pdf," you likely face one of two challenges: either you cannot find a clean, readable copy of the standard online, or you have found a PDF but are struggling to decipher its complex tables and nomenclature. din 5480 spline dimensions pdf

This article serves as a comprehensive guide to understanding the DIN 5480 standard, navigating its dimension tables, and accessing reliable PDF resources for your engineering projects.

The DIN 5480 standard defines the dimensions and tolerances for involute splines used in mechanical engineering, particularly for serrated shaft-hub connections. Unlike older standards (e.g., DIN 5481, DIN 5482), DIN 5480 is based on a reference diameter rather than a nominal or root diameter, enabling modular design and better load distribution.
