"N" indicates a hub (internal spline); "W" indicates a shaft (external spline). 120: The nominal reference diameter ( ) in millimeters. 3: The module ( ), which dictates the tooth size. 38: The total number of teeth ( 9H: The tolerance class and position for the fit. 2. Core Dimensional Formulas
DIN 5480 defines precise tolerances for fit types based on manufacturing capability, commonly utilizing tolerance classes like . These allow for proper centering of the shaft and hub. din 5480 spline dimensions pdf verified
Engineers, machinists, and draftsmen frequently search for "DIN 5480 spline dimensions pdf verified" to ensure their CAD models and manufacturing tolerances match official standards. This article breaks down the foundational math, standard dimensional parameters, and reference data required to design or inspect a DIN 5480 spline interface. 1.
