DIN 5480 Spline Dimensions: A Comprehensive Review

Direct from Beuth Verlag (Official German standards body – paid, but 100% verified).
Engineering Toolbox Pro (Verified excerpts available for free).
Gear calculation software (e.g., MITCalc, HEXAGON) – these generate the specific table you need on demand.

Module范围: Modules from 0.5 mm to 10 mm.
Pressure Angle: Two primary angles—30° (most common) and 37.5° (or 45° for special applications).
Fit System: It utilizes a "side fit" (centering on the tooth flanks) rather than a major or minor diameter fit.
Reference Diameter: The standard is unique because it bases calculations on a reference diameter (dref) rather than just the pitch diameter.

Tolerance Class & Deviation: 8f. The number (8) is the tolerance class, and the letter (f) is the deviation series (e.g., lower case for shafts, upper case for hubs). Verification and Inspection Dimensions din 5480 spline dimensions pdf verified
