Yes, the current version is DIN 5464:2006-09 , confirmed in 2020. The 1986 version is withdrawn.
The DIN 5464 standard documentation includes comprehensive tables for both holes and shafts, essential for designing robust mechanical assemblies. Key areas covered in the document include: 1. Geometry and Dimensions Number of Teeth (
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
Drivetrain linkages for excavators, earthmovers, and heavy-duty hydraulic pump drives. din 5464 standard pdf
Optimized for machine tools requiring high concentricity via internal centering. It features specific, heavy-duty proportions tailored for high precision.
| Standard | Title/Description | Key Difference / Relationship | | :--- | :--- | :--- | | | Straight-sided splines - Heavy series | Defines the heavy series with more teeth for higher load capacity. | | DIN ISO 14 | Straight-sided splines for cylindrical shafts with internal centering | Defines the "medium" series and provides the foundational inspection procedures also referenced by DIN 5464. | | DIN 5466-1 | Splined joints - Calculation of load capacity | Provides calculations for the load capacity of splined joints, including those designed to DIN 5464. | | DIN ISO 6413 | Technical drawings - Representation of splines | Specifies how splines, including those from DIN 5464, should be represented on technical drawings. |
Specifies the necessary manufacturing tolerances to ensure proper fit. Yes, the current version is DIN 5464:2006-09 ,
The DIN 5464-2010 document is concise, comprising only 9 pages. Despite its brevity, it is packed with critical technical information, typically structured as follows:
(Tooth Width): The lateral profile dimension of individual straight keys.
: Heavy industrial machinery, power take-off (PTO) shafts, and high-load mechanical transmissions. Key Technical Specifications Key areas covered in the document include: 1
The DIN 5464 standard establishes the dimensional profiles, tooth counts, boundary geometries, and tolerance zones for straight-sided (parallel-flanked) splines categorized under the "Heavy Series" ( Schwere Reihe ).
But what exactly makes this standard unique, and why should it be on your radar for your next heavy-duty project? What is DIN 5464?
While many third-party engineering blogs offer summarized dimension charts, the official, legally binding must be purchased through authorized distributors such as Beuth Verlag or the ISO Store. Utilizing unauthorized or outdated PDFs from unverified sources can result in using obsolete tolerances, causing structural failures or mating components that do not fit.
