Din 5480 Spline Dimensions Pdf Verified -
This is a technical white paper intended for engineers, machinists, and quality assurance professionals dealing with German standard gearing and splined connections.
6. Tooth Thickness & Space Width (at reference diameter)
- For basic rack tooth thickness =
π*m/2 - Actual values vary by fit class (e.g.,
h,f,e,dfor external;H,G,F,Efor internal).
Key definitions
- Module (m): Basic tooth size; spacing of teeth defined by circular pitch = π·m.
- Number of teeth (z): Teeth count on the spline profile.
- Reference diameter (d): Shaft reference for spline geometry.
- Major diameter (da) / Minor diameter (df): Outside and root diameters for shaft/hub as applicable.
- Tooth thickness (s): Measured at reference diameter.
- Pressure angle (α): Standard involute pressure angle (commonly 30° for DIN 5480).
- Fit classes / tolerances: Defined for shaft and hub to control clearance, transition, or interference fits.
