W denotes a "Welle" (Shaft/External spline); N denotes a "Nabe" (Hub/Internal spline). Reference Diameter: Module ( ): Number of Teeth ( ): Tolerance Class: Comparison with Other Standards
For detailed dimension tables including root diameters, tip diameters, and tooth thicknesses, you can refer to technical guides from manufacturers: Doppler Gear DIN 5480 Decoder
: Ensure easy axial movement without load (e.g., 9H/9g).
standard defines the dimensions and tolerances for involute splines based on a reference diameter. Unlike many other spline standards that rely on major or minor diameters, DIN 5480 uses the reference diameter ( as the primary basis for its calculations. d2t1xqejof9utc.cloudfront.net Core Technical Specifications din 5480 spline dimensions pdf
This is the theoretical diameter where the tooth thickness equals the space width. $$d = m \times z$$
Offers a downloadable table of normalized dimensions according to DIN 5480.
When looking at an engineering drawing or a dimensional PDF, a DIN 5480 spline is designated by a specific string of characters. DIN 5480 – N 120 × 3 × 38 × 9H W denotes a "Welle" (Shaft/External spline); N denotes
A combination like 9H / 9g provides a standard clearance fit with sufficient backlash for easy assembly and lubrication clearance. A combination like 7H / 7h provides a tight, high-precision fit with minimal rotational play. 6. Manufacturing and Measuring DIN 5480 Splines
ball bearing onto the new spline shaft. Why?
Involute splines are critical components in mechanical engineering, providing a robust method for transmitting high torque between shafts and hubs. Among the various standards governing these connections, the standard stands out as the primary standard for involute splines in European and many global engineering applications. Unlike many other spline standards that rely on
The standard is divided into several parts, with the most relevant being: Part 1 - Cloudfront.net
