A DIN 5482 spline dimensions calculator uses standard involute gear tooth geometry modified for specific clearance rules. Below are the foundational formulas used to calculate both external (shaft) and internal (hub) splines. Nomenclature and Variables = Number of teeth = Pitch diameter = Base diameter da1d sub a 1 end-sub = Tip diameter (External / Shaft) df1d sub f 1 end-sub = Root diameter (External / Shaft) da2d sub a 2 end-sub = Tip diameter (Internal / Hub) df2d sub f 2 end-sub = Root diameter (Internal / Hub) = Pressure angle (Always 30°) The Equations

: Used when the hub and shaft must act as a single rigid unit, often requiring thermal expansion (heating the hub) for assembly.

): The total count of teeth on the external spline (shaft) or slots on the internal spline (hub). Fixed strictly at 30 degrees for all DIN 5482 profiles. Pitch Diameter ( din 5482 spline dimensions calculator

Because DIN 5482 relies on non-standard profile shifts to maintain specific nominal outer and inner boundaries, standard gear formulas fail. A digital calculator executes calculations using a three-step workflow: Step 1: Profile Shift Lookup (

The DIN 5482 standard may be a legacy specification, but its straight-sided splines are still found in equipment built to last decades. Whether you are repairing agricultural machinery, reproducing vintage automotive parts, or maintaining power plant gearboxes, a reliable saves hours of reference work and eliminates costly machining mistakes.

You typically have two choices at this stage:
