A standard dimensions PDF lists values generated by strict geometric formulas. If you do not have the lookup tables on hand, you can calculate the nominal dimensions using the formulas below. Fundamental Parameters: Module (
DIN 5480 utilizes the classic ISO deviation system to manage the backlash and fit between the shaft and hub.

Let’s decode that:
| Parameter | External Spline (Shaft) | Internal Spline (Hub) | |-----------|------------------------|----------------------| | Reference diameter | 60.0 mm | 60.0 mm | | Tip diameter | 64.0 mm | 56.0 mm | | Root diameter | 55.0 mm | 65.0 mm | | Space width / Tooth thickness (max/min) | 3.1416 / 3.0916 mm | 3.1916 / 3.1416 mm |
In the world of mechanical engineering, torque transmission between a shaft and a hub is a fundamental challenge, and the solutions are often splines. Among the many global standards, the stands out for its unique and practical design philosophy. Understanding its dimensions and how to find the official specification documents—often searched for as a "DIN 5480 spline dimensions pdf"—is critical for any engineer involved in drive technology, automotive design, or mechanical power transmission.
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. din 5480 spline dimensions pdf
DIN 5480 splines are manufactured using specialized tools like hobs and broaches, which are covered in the standard. They are used in a variety of applications, including:
Quality inspections, tolerances, and gauging requirements.
is the tolerance class (5–12); f is the deviation (lower case for shafts, upper case for hubs). Fundamental Dimension Formulas Calculations for DIN 5480 involve profile shifts ( A standard dimensions PDF lists values generated by
The standard ensures that by selecting a standard module and reference diameter, manufacturing tools are standardized, reducing costs and lead times. 5. Summary Table (Conceptual Example)
Provides high tooth strength and efficient load distribution.
| Parameter | Specification | Details | | :--- | :--- | :--- | | | 30° | This is a fixed value for the entire standard. | | Module Range | 0.5 to 10 | Modules are metric and cover a wide range of tooth sizes. | | Number of Teeth | 6 to 82 | Includes both low and high tooth counts. | | Profile Shift | Shaft: -0.05·m to +0.45·m Hub: +0.05·m to -0.45·m | Allows for variation to meet different fit requirements. | ) are you planning to use
This is the most common fit type under DIN 5480. The teeth contact each other on the flanks, allowing the radial forces to self-center the assembly. Common Hub Tolerances: 9H, 7H Common Shaft Tolerances: 9g, 8f, 7h
