The DIN 5464 standard is an engineering specification for straight-sided splines (also known as parallel splines or heavy series splines), specifically focused on the heavy-duty series with internal centering. Overview of DIN 5464

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). Type: Straight-sided (Parallel) Splines. Series: Heavy-duty series.

Centering: Internal centering (centering on the minor diameter).

Application: Heavy industrial machinery, power take-off (PTO) shafts, and high-load mechanical transmissions. Key Technical Specifications

The standard provides a dimensional matrix based on the number of teeth ( ) and the nominal diameter ( ). Parameter Description Number of Teeth ( ) Typically 8, 10, or 20, depending on the shaft size. Minor Diameter ( ) The inner diameter where centering usually occurs. Major Diameter ( ) The outer diameter of the spline teeth. Width of Key ( ) The thickness of the individual spline teeth. Status and PDF Access

The DIN 5464:1965-09 version was the long-standing baseline for this series. However, modern engineering often references updated ISO equivalents.

Withdrawal Status: Many older DIN spline standards have been formally withdrawn or superseded by international standards like ISO 14 (Straight-sided splines for cylindrical shafts).

Official Copies: You can purchase the official full-text PDF through authorized distributors like DIN Media or the Beuth Publishing House.

Technical Manuals: For quick reference of the dimensional tables without buying the full standard, engineering catalogs from manufacturers like Garlock or mechanical design handbooks often include these spline charts. Common Use Cases din 5464 standard pdf

This standard is frequently used in European machinery design for:

Sliding Couplings: Where the hub must slide along the shaft under load.

Fixed Connections: High-torque permanent fits between shafts and gears.

Repair & Maintenance: Identifying legacy spline profiles on older industrial equipment.

The DIN 5464 standard specifies the requirements for straight-sided splines in the heavy series, designed for both fixed and moving shaft-hub connections. This standard is critical in mechanical engineering for transmitting high torque through thin-walled hubs, as its 0∘0 raised to the composed with power pressure angle prevents hub expansion from radial forces. Key Specifications of DIN 5464

The standard provides the geometry, dimensions, and tolerances necessary for manufacturing and inspecting these heavy-duty spline connections. Designation: Straight-sided splines - Heavy series.

Current Version: DIN 5464:2010-03, which replaced the older 1965 edition. Pressure Angle: 0∘0 raised to the composed with power (straight flanks).

Centering: Typically flank-centered, though internal or diameter centering may be defined for specific applications.

Teeth Count: The heavy series features more teeth compared to DIN ISO 14, providing a significantly higher load capacity. Applications and Advantages

DIN 5464 splines are preferred in heavy-duty machinery where space is limited but torque requirements are high. DIN 5464 Standard: Splined hubs and spline shafts

High Load Capacity: The increased number of keys/teeth allows for greater torque transmission than the light or medium series (such as DIN 5462 or DIN 5463).

Structural Integrity: Because the flanks are parallel, the forces are purely tangential. This eliminates the radial "bursting" force on the hub, allowing engineers to use low hub wall thicknesses.

Compatibility: The internal diameter gradation is consistent across the light, medium, and heavy series, often designed to be 1–2 mm larger than standard ball-bearing diameters for easier assembly. Where to Obtain DIN 5464 PDF

Official copies of the standard are available for purchase from authorized distributors in digital PDF or print formats:

DIN Media (Beuth): The primary source for the official DIN 5464:2010-03.

ANSI Webstore: Provides the DIN 5464 PDF with immediate download options.

European Standards: Another reliable platform for purchasing the standard documentation.

The document is approximately 9 pages long and is published in both German and English.

Step 2: Define Fit Type

  • Sliding fit (H/h): For clutches or shifting gears. Allows axial movement.
  • Fixed fit (H/k or H/js): For permanent couplings. No axial movement under load.

Q4: Can I 3D print a spline from the DIN 5464 PDF?

A: Yes, for prototyping. Use the internal and external dimensions from the PDF. However, note that 3D printed tolerances (±0.1 mm) are much looser than the standard’s machining tolerances (±0.01 mm).

DIN 5464 vs. DIN 6923

  • DIN 6923 specifies coarse pitch thread hexagon flange nuts.
  • DIN 5464 specifies fine pitch thread hexagon flange nuts.
  • Key takeaway: Use DIN 6923 for standard bolts; use DIN 5464 for fine-thread high-stress applications.

Q1: Is DIN 5464 still active?

A: Yes, the current version is DIN 5464:2006-09, confirmed in 2020. The 1986 version is withdrawn. Dimensions and tolerances for splined hubs and spline

Step 3: Generate the Tooth Geometry

Using data from Table 2 of the PDF:

  • Calculate the base circle diameter.
  • Generate the involute curve using a parametric equation in SolidWorks, Fusion 360, or AutoCAD.
  • Pro tip: Many CAD tools have a "DIN 5464 Spline" wizard built-in. You can input the module, tooth count, and fit class directly.
