Primarily flank-centered, but can be tip-centered or root-centered depending on the application. Understanding DIN 5480 Spline Designation
DIN 5480 is a German standard that defines the dimensions, tolerances, and design characteristics of with a 30∘30 raised to the composed with power
). A positive shift increases the tooth thickness and major diameter of the shaft, while a negative shift decreases them. Always check the specific part part-number designation for its profile shift value. 3. Verified Reference Dimensions Table (Common Sizes)
Indicates a Shaft ( Welle ). N indicates a Hub/Internal Spline ( Nabe ). 40: The Reference Diameter ( 2: The Module ( 18: The Number of Teeth ( 4. How to Verify PDF Data Sheets and CAD Models din 5480 spline dimensions pdf verified
Are you designing the or the external shaft component?
Because measuring involute flanks directly is highly impractical with standard calipers, inspectors calculate dimensions by placing calibrated pins or balls into the tooth spaces. Measured as Dimension Over Pins ( Mecap M sub e ) . Internal Splines: Measured as Dimension Between Pins ( Micap M sub i ) . Exact pin dimensions depend heavily on the module (

Look for 2006-03 in the footer. If 1991-10 is present, the dimensions for module 0.6 are invalid.
Where dm = ball diameter (0.6m to 1.1m typically).
This part details the design features of tools used in manufacturing, such as hobs, pinion-type cutters, and broaches. The data ensures that these tools can accurately produce splines that conform to the standard. N indicates a Hub/Internal Spline ( Nabe )
