DIN 5480 standard governs involute splines based on reference diameters, primarily used for high-precision torque transmission in mechanical engineering. Unlike ISO 4156, DIN 5480 allows the reference diameter to be independent of the module, making it easier to match splined components with standardized ball or roller bearings. d2t1xqejof9utc.cloudfront.net Core Geometric Specifications The standard specifies a 30° pressure angle
Producing DIN 5480 splines requires specialized machinery to maintain the involute profile accuracy.
| 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. |
A is an indispensable tool for anyone designing or inspecting involute spline connections. Whether you need a quick reference for tooth geometry or detailed inspection data, having accurate, standard-compliant dimensions ensures reliable torque transmission and long service life. din 5480 spline dimensions pdf
The standard defines the dimensions and tolerances for involute splines used in mechanical engineering, particularly for serrated shaft-hub connections . Unlike older standards (e.g., DIN 5481, DIN 5482), DIN 5480 is based on a reference diameter rather than a nominal or root diameter, enabling modular design and better load distribution.
