Spline Shaft DIN 5464 - 10×36×45Spline Shaft DIN 5464 - 10 cross 36 cross 45
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 standard pdf
The "flange" feature (an integrated washer-like base) distributes the clamping load over a wider surface area, eliminating the need for a separate washer.
In the world of mechanical power transmission, precision is everything. If you are working with heavy-duty shaft-hub connections, you’ve likely come across .

standard specifies the requirements for straight-sided splines used in both fixed and moving shaft-hub connections. Unlike standard series, the "heavy series" defined here features a higher number of teeth, which significantly increases load capacity compared to the general DIN ISO 14 standards. Key Technical Features: 0° Flank Angle:
The standard provides a "proven design" shortcut. Instead of calculating module and profile shifts from scratch (as one might using DIN 5480), an engineer can select a DIN 5464 profile by diameter and number of teeth, confident that the geometry has been stress-tested by decades of industrial use.

The DIN 5464 standard establishes the specific geometry for parallel spline joints. The primary characteristic of this standard is (also known as minor diameter centering).
