This part contains exhaustive data tables. If you need to look up the exact major diameter, minor diameter, and tooth thickness for a specific shaft or hub designation, this is the document required. It provides the reference dimensions for modules ranging from 0.5 to 10. 3. DIN 5480-15: Spline Inspection (Gauging)
Are you designing an or an internal hub (N) ? What is your required module or number of teeth ?
Allows components to slide axially while stationary or under light load.
: Curve profiles distribute loads evenly across all active teeth.
: It covers modules from 0.5 to 10 , with tooth counts ranging from 6 to 82 . Din 5480 Pdf
Establishes the core foundation, including basic rack profile, preferred modules/reference diameters, symbols, and fit system for tooth thickness. Covers basic calculations, tolerances, and deviations.
DIN 5480-15 provides the exact values for "dimensions over/between pins." This is the only way machinists can verify the pitch diameter using precision wire pins during manufacturing.
db=d×cos(30∘)d sub b equals d cross cosine open paren 30 raised to the composed with power close paren p=π×mp equals pi cross m
Offers specific formulas for addendum modification ( x.m ), which is necessary for high-load, high-precision applications. Where to Find DIN 5480 PDF Documentation This part contains exhaustive data tables
I can calculate the nominal geometric dimensions or help you interpret your drawing's designation. Share public link
Dimensions are calculated using metric modules ( ) rather than diametral pitch.
When reviewing engineering drawings, DIN 5480 splines are specified using a standardized alphanumeric string. Deciphering this code is essential for manufacturing. DIN 5480 – W 120 x 3 x 38 x 8f Breaking down the code: DIN 5480: The governing standard.
Warning: Many free PDFs circulating online are the 1991 version. While similar, the 2006 version contains critical changes to tolerance calculation and inspection methods. Using the wrong version can lead to splines that bind (too tight) or rattle (too loose). Allows components to slide axially while stationary or
: A web-based solution for calculating main geometries, tooth form, inspection dimensions, tolerances, and strength of involute splines according to DIN 5480.
Indicates whether it is a Shaft ( W for Welle ) or a Hub/Internal Spline ( N for Nabe ). 120: The nominal design diameter ( ) in millimeters. 3: The module ( ), which dictates the tooth size. 38: The total number of teeth ( 8f: The tolerance class and position (similar to ISO fits). Fundamental Formulas and Geometry
The tip diameter of the external spline (shaft) centers directly against the root diameter of the internal spline (hub).
