Ensure your manufacturing partner has the correct module-cutters or broaches matching the specified module and pressure angle.
Splines are typically centered by the flanks of the teeth, allowing minor clearances at the major and minor diameters. Module System: Uses metric modules ( ) ranging from 0.5 to 10 to define tooth size. 2. Structure of the DIN 5480 Standard Series
DIN 5480 provides the necessary standardization for high-performance involute splines. Accessing a is crucial for proper CAD design and manufacturing. Always ensure you are using the most current version of the standard to ensure compatibility and performance. din 5480 spline dimensions pdf
The engineer fell into the classic DIN 5480 trap. In this standard, the number
If you work in mechanical engineering, automotive drivetrain design, or precision machining, you’ve likely encountered the standard. It is the go-to specification for involute splines based on reference diameters, used heavily in Germany and across Europe. Always ensure you are using the most current
Defines the total number of splines on the circumference.
does equal the physical outer diameter. It is the Reference Diameter ( dBd sub cap B ). Because DIN 5480 utilizes a 30∘30 raised to the composed with power 2. Core Dimensional Formulas
): The core diameter used for labeling (e.g., DIN 5480 N30). Determines the tooth size and spacing. Number of Teeth ( ): Defines the density of the spline. Pitch Diameter ( ): Calculated as
: "W" (Welle) denotes an external shaft; "N" (Nabe) denotes an internal hub.
: The tolerance class for the space width or tooth thickness. 2. Core Dimensional Formulas
