M_external = dref * cos(α) / cos(α_M) + dm
| | Specification | |:---|:---| | Standard Series | DIN 5480 (replacing older DIN 5480-2 through DIN 5480-13) | | Tooth Profile | Involute splines | | Module Range (m) | 0.5 mm to 10 mm | | Number of Teeth (z) | 6 to 82 | | Pressure Angle (α) | 30° (Exclusively; 37.5° and 45° are covered by ISO 4156) | | Basis of the System | Reference Diameter (dB) , independent of the module |
When searching for a source, engineers must understand the underlying geometry, tolerance systems, and verification methods required to implement these standards accurately. Understanding the DIN 5480 Standard
DIN 5480 - N 40×2×18×9HDIN 5480 - N 40 cross 2 cross 18 cross 9 H din 5480 spline dimensions pdf verified
If you are manually checking a PDF table, use these formulas: (for standard series). Pitch Diameter: Base Diameter: Circular Pitch: 📑 Common Spline Dimension Tables
This is the fingerprint of the involute. For DIN 5480 with a 30° pressure angle (α), the base pitch must equal π * m * cos(30°) . A verified PDF lists this for every module.
Pick a random spline size. Example: Module 2, teeth z=28, 30° PA. M_external = dref * cos(α) / cos(α_M) +
For detailed nominal and inspection tables (measuring over pins/balls), refer to the following official parts of the standard: Din 5480-2 | PDF | Engineering Tolerance | Gear - Scribd 29 Dec 2012 —
By adhering to the DIN 5480 standard, you ensure that your gear splines are interchangeable and capable of handling maximum load. Always verify your PDF documentation is up-to-date, typically referencing the 2006-03 or later revisions.
Scroll to the bottom of the PDF. Does it include the Tabelle 1 for fundamental deviations (A, B, C, D, E, F, G, H, J, K)? If not, you cannot assign a fit class. For DIN 5480 with a 30° pressure angle
The following table outlines standard dimensions for common module 2 and module 3 side-fit configurations. Always verify these values against official certified PDF data sheets prior to tooling setup. Designation Code Number of Teeth ( Reference Diameter ( External Major Diameter ( da1d sub a 1 end-sub Internal Minor Diameter ( df2d sub f 2 end-sub W 30 x 2 x 13 W 40 x 2 x 18 W 50 x 3 x 15 W 60 x 3 x 18 How to Verify a DIN 5480 PDF Data Sheet
This article breaks down the DIN 5480 series, explains where to find official dimension tables, and guides you through verifying their authenticity.
To ensure your engineering designs are accurate, verify your files carefully. If you want, tell me: What specific or module size do you need? Are you designing the internal hub or the external shaft ? What tolerance class does your application require? Share public link
