Once you have your official , here is how to apply it: Din 5480 Pdf

DIN 5480 is a German standard for based on reference diameters. It is widely used in mechanical engineering for power transmission between shafts and hubs.

"N" denotes a Hub (internal spline). "W" denotes a Shaft (external spline). 40: The Reference Diameter ( ) in millimeters. 2: The Module ( ), which determines the size of the teeth. 18: The Number of Teeth ( 9H: The Tolerance Class (e.g., 9H for hubs, 8f for shafts). Core Formulas : Side-fit (flank centering) is the standard method,

: Unlike other standards (like ISO 4156), DIN 5480 is based on reference diameters that are independent of the module.

The metric unit that indicates the size of the teeth. A module of 3 means the teeth are relatively robust. It is widely used in mechanical engineering for

A standard designation follows this format:

Exact data on addendums (h = 0.45 ⋅ m), dedendums (h = 0.60 ⋅ m), and tooth depths.

DIN 5480 is a German standard published by the Deutsches Institut für Normung (DIN). It specifies the geometry, dimensions, tolerances, and gauging practices for involute splines based on module pitches.
