Usually flank-centered , where the tooth flanks transmit torque and center the shaft and hub. Decoding the Designation

The following values represent nominal dimensions before tolerances are applied. Reference Dia ( Number of Teeth ( Shaft Major Dia ( da1d sub a 1 end-sub Hub Minor Dia ( di2d sub i 2 end-sub Tolerance Classes and Fits din 5480 spline dimensions pdf

Define the peaks and valleys of the teeth. Common Standard Tables Usually flank-centered , where the tooth flanks transmit

The splines are typically side-fitting, meaning the contact occurs on the flanks rather than the major/minor diameters. Naming Convention (Decoder) Determines the tooth size and spacing

is the tolerance class (5–12); f is the deviation (lower case for shafts, upper case for hubs). Fundamental Dimension Formulas Calculations for DIN 5480 involve profile shifts (

): The core diameter used for labeling (e.g., DIN 5480 N30). Determines the tooth size and spacing. Number of Teeth ( ): Defines the density of the spline. Pitch Diameter ( ): Calculated as
