: Covers basic parameters and the reference diameter system. DIN 5480 Calculation Guide

DIN 5480 specifies involute splines with parallel-sided teeth for shaft-to-hub connections, widely used in mechanical power transmission where precise axial positioning and torque transfer are required. Below is a concise, verifiable summary of the key dimensional features and design considerations you can use as a quick reference. For official tables and tolerances, consult the published DIN 5480 PDF standard.

: Focus on specific inspection methods and measurement tolerances. Decoding the DIN 5480 Designation

Internal splines (hubs) are defined by (E). External splines (shafts) are defined by tooth thickness (s). A verification check: For a zero-backlash fit, E_min = s_max.

DIN 5480 was introduced in 1986 (and revised in 1991 and 2006) to replace the older DIN 5481 and DIN 5482 standards. Unverified PDFs often mix these older standards, leading to catastrophic mismatches. Using an unverified document can result in:

: These are adjusted based on the profile shift to maintain a standardized clearance ( ), typically Addendum ( ) and Dedendum ( ) : Standard values are often for the addendum and for the dedendum in hobbed splines. Verification and Measurement Din 5480-1 | PDF - Scribd
