Typically d + 0.5 × m External Spline Minor Diameter (d₄): Typically d - m 3. Pin Measurement Calculator For accurate manufacturing, the measurements over pins ( Mpcap M sub p ) or between pins ( Micap M sub i

Should we add to the output sheet?

The top and bottom boundaries of the teeth differ slightly depending on whether you are designing the shaft or the hub. These values ensure proper radial clearance when the parts slide together.

Modern calculators provide more than just basic dimensions. Key advanced features include:

Before releasing an Excel template to your engineering team, verify its outputs against standard reference charts provided directly by DIN.

Understanding the differences between DIN 5480 and other global standards is essential for any engineer. Typically d + 0

✅ ✅ Tooth count up to 100 ✅ Support for all three centering types (MA, MI, F) ✅ Measurement over pins for both shaft and hub ✅ Backlash calculation based on fit class ✅ Graphical representation of spline (optional) These values ensure proper radial clearance when the

You won’t see the spline profile – mistakes in input (e.g., wrong root geometry) are easy to miss.

The DIN 5480 standard is based on reference diameters and a module system. Unlike other standards that focus on the number of teeth, DIN 5480 prioritizes the fit between the shaft and the hub. Key parameters include:
