Initial searches might incorrectly connect DIN 5464 to topics like nuts (DIN 6923) or aerospace parts (DIN 65246). DIN 5464 is exclusively about straight-sided splines .
Following the DIN standard ensures that parts from different manufacturers fit together correctly. Accessing the DIN 5464 Standard PDF
: Straight-sided (parallel, non-involute) flanks featuring a 0° pressure angle.
Many technical universities and large engineering firms have site licenses. If you work for or study at such an institution, check their internal digital library.
As industries digitize their technical libraries, the search for the "DIN 5464 standard PDF" has become a routine task for engineers and procurement officers. However, finding the document is only the first step; understanding the geometric precision it dictates is where the real engineering begins. din 5464 standard pdf

The standard defines specific fits (e.g., tight or loose) depending on whether the spline is meant for fixed or sliding connections.
Typically flank-centered, though additional diameter centering can be defined.
Despite high capacity, the heavy series provides a compact design compared to alternative connecting methods.

: The high surface area contact makes it highly resistant to wear under shock loads, rapid reversals, and high-frequency alternating torques.
The standard, titled "Straight-sided splines - Heavy series," is the current German technical specification for high-torque shaft-hub connections. This heavy-duty series features more teeth than standard profiles (like DIN ISO 14), allowing for greater load capacity and thinner hub walls. Key Specifications
DIN 5464 defines the dimensions, tolerances, and design requirements for splined shafts and hubs that are intended for high-torque applications. It is part of a family of standards that includes DIN 5462 (light series) and DIN 5463 (medium series). : Straight-sided (Parallel) Splines. Series : Heavy-duty series.
