When designing a connection using the DIN 5480 standard, always ensure you have finalized the following parameters before sending files to production:

da1=m×(z+1)d sub a 1 end-sub equals m cross open paren z plus 1 close paren

DIN 5480 profiles are split into external splines (shafts) and internal splines (hubs). They feature specific tip and root diameter limits to ensure proper clearance during engagement. Shaft (External Spline) Dimensions : The maximum outside diameter of the shaft. Root Diameter ( df1d sub f 1 end-sub

(Note: Full PDF tables include values up to 500 mm reference diameter)

Because measuring an involute curve directly is difficult, DIN 5480 mandates specific measurement methods: Measurement Over Pins/Balls ( Mkcap M sub k

pressure angle and a reference diameter based on the module system.

pressure angle . Unlike other spline standards (like ISO 4156, which uses a 37.5∘37.5 raised to the composed with power 45∘45 raised to the composed with power

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

The standard defines several types of splines, including:

If you cannot locate a clean , consider these engineering workarounds:

In the world of mechanical engineering, connecting a shaft to a hub requires precision, strength, and reliability. While keyed connections are common, they often fall short when dealing with high torque or dynamic loads. Enter the involute spline—a robust solution standardized under .

DIN 5480 is the German standard for , widely used in mechanical engineering for high torque transmission and precise alignment. Unlike other standards that rely on the major or minor diameter, DIN 5480 uses a reference diameter ( dBd sub cap B

Unlike minor-diameter or major-diameter centering systems, DIN 5480 primarily relies on the flanks of the teeth to align the shaft and the hub. Reference Diameter (
