To accurately inspect a spline shaft, one needs the nominal and inspection dimensions provided in and the precise inspection methods described in DIN 5480-15 .

Below is a partial breakdown of common DIN 5480 specifications based on standard tables. Nominal Diameter (mm) Module (m) Number of Teeth (z) Reference Diameter ( Drcap D sub r din 5480 spline dimensions pdf verified

Module 1.5, 26 teeth, Class 8f.

The following reference table presents verified nominal dimensions for common DIN 5480 configurations. These dimensions form the baseline profile before tolerance classes (such as 9g or 8H) are applied.

In mechanical engineering, there is no substitute for verified data. The is more than just a document; it is the legal and technical foundation of any high-quality spline connection. Using a verified, purchased PDF from an authorized source provides the assurance that your design complies with the most current and precise standards from the German Institute for Standardization.

: Interference or transition fits, used when backlash must be entirely eliminated. 5. Verification Checklist for Designing with DIN 5480

Verified PDFs typically include three main sections for each module: External Spline (Shaft) Definition Major Diameter deed sub e e end-sub Top of the tooth crest Form Diameter dfed sub f e end-sub Limit of useful flank Minor Diameter died sub i e end-sub Root of the shaft Internal Spline (Hub) Definition Major Diameter daid sub a i end-sub Root of the internal spline Form Diameter dfid sub f i end-sub Limit of useful flank Minor Diameter diid sub i i end-sub Tip of the internal tooth 🛠 How to Verify Your PDF Data Nominal Diameter (mm) Module (m) Number of Teeth

When reading a blueprint or ordering a verified PDF data book, designations are formatted as follows:

Once you have your verified PDF of DIN 5480-2, understanding its layout is key to efficient use. The standard is organized by module size, starting from and going up to Module m = 10 mm . For each module, the PDF contains a series of tables (such as the example in [图1] below) providing pre-calculated values for every combination of reference diameter (dB) and number of teeth (z) within its scope.

The DIN 5480 series is the German national standard for involute spline connections. Unlike the ISO standard (ISO 4156), which is based on a series of modules, DIN 5480 is unique because its spline dimensions are based on a series of stepped "reference diameters" that are independent of the module.
