(Width of Spline/Tooth): The thickness of the parallel keys on the shaft or the width of the slots in the hub.
or DIN 5463), the "Heavy Series" defined by DIN 5464 is specifically engineered for applications requiring high torque transmission through relatively thin hub walls. Technical Characteristics Pressure Angle: These splines feature a 0° flank angle

The bore of the mating hub is similarly machined to fit tightly over this minor diameter.

(Minor/Internal Diameter): The innermost base circle of the spline shaft. (Major/External Diameter): The outermost tip circle.
Note: While DIN 5464 details unique heavy-series geometries, it adopts the underlying inspection and validation procedures defined in DIN ISO 14. Industrial Applications
is the active German technical standard that specifies the geometry, tolerances, and design requirements for straight-sided splines in the heavy series . This mechanical engineering standard dictates the parameters for secure shaft-hub connections designed to transmit exceptionally high torques under harsh operational loads. The current and active version of this document is DIN 5464:2010-03 , which directly replaced the vintage 1965 edition.
