Verified Resource: Understanding DIN 5480 Spline Dimensions (PDF Download)
In mechanical engineering, power transmission requires high precision and reliability. is the global standard for involute splines with a 30° pressure angle. Understanding these geometric profiles is critical for ensuring smooth torque transfer, minimizing wear, and preventing catastrophic component failure.
rule: Multiply the number of teeth by the module. Does it match the pitch diameter ( Module 1
where z = number of teeth (integer, usually even for internal splines).
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 provides a flexible, modular system for splined connections that prioritizes and standardized tooling . If you'd like, I can: 7H/7e or 8H/8f (Good for precision and high-load torque)
): Dictates the size of the tooth. Standard modules range from 0.5 to 10.
(Profile Shift Factor): The intentional shift applied to the cutting tool to achieve specific clearance, strength, or backlash characteristics. DIN 5480 Spline Dimension Formula Architecture
A standard PDF on dimensions is incomplete without the tolerance class system. DIN 5480 is unique in its approach to fit allocation:
