When looking at an engineering drawing or a dimensional PDF, a DIN 5480 spline is designated by a specific string of characters. DIN 5480 – N 120 × 3 × 38 × 9H

. Confident, they model the part and send it to the machine shop. din 5480 spline dimensions pdf

Typically designated with capital letters (e.g., 9H , 7H ). The 9H class is the most common industry standard for general machinery.

db=d×cos(30∘)=d×0.866025d sub b equals d cross cosine open paren 30 raised to the composed with power close paren equals d cross 0.866025 External Spline (Shaft / "W") Nominal Sizes: db=dB×cos(30∘)=dB×0

indicates an Internal Spline (Hub/Bore). W indicates an External Spline (Shaft). 120 Reference Diameter ( The nominal dimension around which the spline is designed ( 3 The pitch module, which dictates tooth size ( 38 Number of Teeth ( The total count of splines around the circumference ( 9H or 8f Tolerance Class

A key characteristic of the DIN 5480 series is its limitation to a for all spline profiles. This choice is fundamental to the standard's design rules and simplifies tooling. The standard is structured into four main parts, consolidating what was once sixteen individual documents: Hub Minor Diameter ( ): The inner bore

Using CAD software (e.g., Autodesk Inventor, SolidWorks):

For engineers and designers, having the official DIN 5480 PDF tables is essential. While the standard itself is proprietary, many technical suppliers provide summarized charts.

General principles, basic definitions, and the fundamental structure of the spline system.

The reference diameter is the primary theoretical pitch circle. d=m×zd equals m cross z Base Diameter (
