Din 5464 Standard Pdf ((free)) [ SAFE ✰ ]
Because it resists radial expansion while carrying severe loads, the DIN 5464 profile is widely utilized across heavy industrial sectors:

is the active German technical standard that specifies the geometry, tolerances, and design requirements for straight-sided splines in the heavy series . Managed by the Deutsches Institut für Normung (DIN) , the current version is DIN 5464:2010-03 , which directly replaced the vintage 1965 edition. Engineers utilize the official DIN 5464 standard PDF to manufacture highly robust shaft-hub connections capable of transmitting immense mechanical torques while minimizing radial stresses. Key Technical Specifications of DIN 5464
The DIN 5464 standard is ubiquitous in applications requiring the transmission of extreme forces without slippage. You will commonly find these spline profiles in: din 5464 standard pdf
: The primary source for German standards.
: Power Take-Off (PTO) shafts on tractors and harvesters.
Offers detailed scope and document history for technical reference. DIN 5464:2010 - Straight-sided splines - Heavy series Because it resists radial expansion while carrying severe
: It specifies the "fits"—how tightly the shaft and hub should slide or lock together—to ensure parts made by different manufacturers are compatible.
Components align via the sides of the keys. This is the default approach for handling alternating torques.
These are parallel-sided splines with a 0° pressure angle, making them robust and reliable for heavy industrial use. Engineers utilize the official DIN 5464 standard PDF
While has largely replaced straight-sided splines in high-volume automotive applications due to lower stress concentrations, DIN 5464 remains indispensable for heavy industrial machinery where sliding fits and minor-diameter guidance are necessary. Manufacturing and Inspection
In the world of precision mechanical engineering, transmitting high torque between a shaft and a hub is a fundamental challenge. While simpler components like parallel keys work for many applications, they can quickly reach their limits under higher loads or in confined spaces. This is where the solution lies. The is the definitive technical document that defines the specific requirements for these robust and efficient mechanical connections.
Unlike lighter profiles, the heavy series maximizes the number of teeth relative to the shaft diameter. This design choice increases the total contact surface area, which optimizes surface pressure distribution. Mechanical Principles 0∘0 raised to the composed with power
To choose the correct component geometry, it is important to understand where DIN 5464 sits compared to similar standards: Series Type Profile Geometry Common Application Heavy Series Straight-sided (0° flank angle) High torque, thin-walled hubs, heavy machinery DIN ISO 14 (formerly DIN 5462/5463) Light/Medium Series Straight-sided (0° flank angle) General automotive, low-to-medium torque DIN 5480 Involute Splines 30°/37.5°/45° Pressure angle
