DIN 5464 is a German standard for heavy-series straight-sided splines designed for high-load power transmission, with the current 2010-03 edition replacing the 1965 version. It features a 0° flank angle for efficient torque transmission and is primarily used to manage high loads in shaft-hub connections.

The DIN 5464 standard specifies the requirements for straight-sided splines (heavy series) used in fixed and moving shaft-hub connections. This standard is critical for engineering applications requiring high torque transmission with minimal hub expansion. Overview of DIN 5464
DIN 5464 belongs to a family of German standards for parallel-sided splines. Unlike the light (DIN 5471) or medium (DIN 5472) series, the heavy series defined in DIN 5464 features a higher number of teeth, which significantly increases its load capacity. The standard primarily focuses on:
Geometry and Dimensions: Defines the physical profile of the splines for both the shaft and the hub.
Tolerances: Specifies the necessary manufacturing tolerances to ensure proper fit.
0° Flank Angle: This design ensures that torque is transmitted without radial force components, preventing the hub from expanding—a crucial factor when working with low hub wall thicknesses. Technical Specifications
According to the latest DIN 5464:2010-03 revision, these splines are typically flank-centered, meaning the torque-transmitting faces of the teeth align the shaft and hub. However, designers may also specify additional diameter centering if required by the application. Specification Profile Type Straight-sided (Parallel) Series Heavy Series Pressure Angle Primary Use High-torque fixed/moving connections Standard Status Active (Last revised March 2010) Practical Applications
The DIN 5464 standard is widely used in heavy-duty mechanical engineering, including:
Industrial Gearboxes: Where high torque must be transmitted reliably.
Driveshafts: For heavy machinery and automotive applications requiring robust connections.
Power Take-Off (PTO) Shafts: Common in agricultural and industrial equipment. How to Access the DIN 5464 Standard PDF

Understanding DIN 5464: The "Heavy Series" of Straight-Sided Splines
In the world of mechanical engineering, connecting shafts and hubs to transmit high torque requires precision and strength. While many engineers are familiar with the general standard DIN ISO 14, those dealing with more demanding, high-load applications often turn to DIN 5464. What is DIN 5464?
DIN 5464 is the German technical standard for Straight-sided splines – Heavy series. Unlike light or medium series splines, this "Heavy Series" is specifically designed for shaft-hub connections that must endure significant stress.
The current version of this standard is DIN 5464:2010-03. It provides the exact geometry, dimensions, and tolerances required to manufacture these components. Why Use the Heavy Series?
The Heavy Series specified in DIN 5464 offers several advantages for specialized machinery:
Higher Load Capacity: Compared to the standard DIN ISO 14, DIN 5464 splines feature more teeth, allowing them to distribute torque over a larger surface area.
Low Hub Wall Thickness: The 0° flank angle prevents radial forces from expanding the hub, making it ideal for high-torque transmission where hub space or material thickness is limited.
Flank-Centered Design: These connections are typically flank-centered, ensuring stable alignment during power transmission. Key Specifications
The standard covers several critical parameters for manufacturing and inspection:
Number of Teeth: Typically 10 or 20 splines, depending on the diameter. DIN 5464 is a German standard for heavy-series
Centering: Primarily flank-centered, though diameter centering is possible.
Inspection Protocols: The fundamental inspection procedures for DIN 5464 align with the details found in DIN ISO 14, though the geometry itself is unique to the heavy series. Where to Find the DIN 5464 PDF

This design prevents the hub from expanding under radial forces, making it exceptionally stable for high-torque applications. Centering Options:
While typically flank-centered, these connections can also utilize additional diameter centering for higher precision. Geometry and Tolerances:
The standard provides 9 pages of detailed geometric data and associated tolerances necessary for manufacturing and quality control. Why the Heavy Series Matters Choosing DIN 5464 over standard profiles like DIN ISO 14
is usually a matter of wall thickness and force. Because the flank angle is zero, the radial component of the flank force is eliminated. This allows engineers to use hubs with thinner walls without risking structural failure under high loads. Where to Access the DIN 5464 PDF
