) are placed opposite each other in the tooth spaces. A micrometer measures the distance across the outside of the pins ( MRcap M sub cap R

If you are working on a specific design, please share your project requirements so we can proceed effectively. Tell me: What is your target and module ? Are you designing the external shaft or the internal hub ?

DIN 5480 is a German standard that specifies the dimensions and tolerances for splines, which are used to transmit rotational motion and torque between two shafts. Splines are a type of mechanical keyway that provides a secure and precise connection between two components. In this paper, we will review the dimensions and specifications of DIN 5480 splines, providing a comprehensive overview of this widely used standard. din 5480 spline dimensions pdf verified

Unlike other standards that fix diameters based on tooth counts, DIN 5480 uses to make the spline fit the space you already have. 📐 Core Dimensions & Geometry Every DIN 5480 spline is defined by its Module ( ), Reference Diameter ( dBd sub cap B ), and Number of Teeth ( ). Formula / Value Pressure Angle Always 30∘30 raised to the composed with power Pitch Circle ( ) Addendum ( ) Dedendum ( ) to (varies by tool) Tip Diameter ( ) 🛠️ How to Read the Code

A fit like 9H / 8f offers a loose/sliding clearance fit, ideal for components that require manual axial movement during assembly or operation. A 9H / 7h fit creates a much tighter profile with minimal backlash, commonly chosen for high-reversing load environments. 6. Verification and Inspection Parameters ) are placed opposite each other in the tooth spaces

You cannot legally get the full, dimensioned PDF for free, as it is a copyrighted publication. You must purchase it from an official distributor. Here are the primary options:

Quality inspections, deviations, and effective fit concepts. The standard utilizes a 30° pressure angle ( Are you designing the external shaft or the internal hub

) : This is a central design value, often chosen to match standard bearing bores, which remains independent of the module. : Profile modification (

Uses the ISO system (e.g., 9g for shafts, 9H for hubs) to control backlash and interference. 2. Core Geometric Formulas

Sector gauges check specific tooth thickness limits. They must not enter or fit across the profile, ensuring the minimum material condition is met. 3. Coordinate Measuring Machines (CMM)

The defines involute splines based on reference diameters, which simplifies the assembly of components like bearings. Unlike other standards that use major or minor diameters as the primary identifier, DIN 5480 uses a Reference Diameter ( dBd sub cap B ) that is independent of the module.
