Note: This is a conceptual example; always consult the official DIN 5480 PDF for precise manufacturing dimensions. Module (m) Number of Teeth (z) Reference Diameter (d) Profile Modification Conclusion
Because measuring an involute curve directly is difficult, DIN 5480 mandates specific measurement methods: Measurement Over Pins/Balls ( Mkcap M sub k
Broaching is highly efficient for through-holes, while shaping is required for blind holes.
Designated by lowercase letters (e.g., f , g , h ). Position h results in zero fundamental deviation (maximum metal condition). din 5480 spline dimensions pdf
Dimensions are calculated using metric modules ( ) rather than diametral pitch.
Given the technical nature of these dimensions, sourcing the official standard is non-negotiable for serious engineering work. Here are the primary ways to obtain the "DIN 5480 spline dimensions pdf":
If you cannot locate a clean , consider these engineering workarounds: Note: This is a conceptual example; always consult

Imagine a young engineer tasked with replacing a high-torque gearbox shaft. The old blueprint has a cryptic callout: .
The reference diameter is the baseline geometry from which the tooth thickness and spacing are calculated. dB=m×zd cap B equals m cross z (Example: For a module 3 spline with 38 teeth: Position h results in zero fundamental deviation (maximum
Features side-fit centering, allowing for high load capacity and centering under torque. Understanding the Dimensions
Defined by the space width on the hub and the tooth thickness on the shaft. Inspection Dimensions ( cap M sub 1 cap M sub 2
Standard tolerance classes include 8f (for shafts) and 9H (for hubs).
The DIN 5480 series applies to splines within the following ranges: 0.5 to 10 Number of Teeth ( ): 6 to 82 Pressure Angle: Strictly 30° How to Read a DIN 5480 Designation
Designated with lowercase letters such as 9g , 8f , or 7h .
