: Involute flanks that allow for self-centering of the shaft and hub.
Despite being withdrawn, DIN 5482 remains highly relevant for specific tasks. Its official status is often described as follows: "In consideration of existing tooling, the present Standard will remain effective until further notice (see Explanations, final paragraph)". This means it is maintained as a reference for:
The following reference index reflects standard structural proportions documented within the classic March 1973 release of DIN 5482-1 , outlining typical tooth counts ( ) and modules ( ) for industrial shafts: Profile Designation Nominal Outer Diameter ( Root Diameter ( Tooth Count ( Profile Shift ( +0.500positive 0.500 A/B 17 x 14 +0.500positive 0.500 A/B 20 x 17 +0.500positive 0.500 A/B 25 x 22 +0.500positive 0.500 A/B 28 x 25 +0.500positive 0.500 A/B 35 x 31 +0.500positive 0.500 Note: Tooth gap tolerances (
The DIN 5482 spline standard is a widely used specification in the engineering and manufacturing industries, particularly in the design and production of mechanical components, such as gears, shafts, and other power transmission systems. This standard defines the requirements for splines, which are toothed components that transmit rotational motion and torque between two or more parts. In this article, we will explore the DIN 5482 spline standard, its significance, and provide a detailed overview of the file type PDF77.
DIN 5482 specifies the dimensions and tolerances for involute splines with a 30-degree pressure angle. Splines are ridges or teeth on a drive shaft that mesh with slots in a mating hub, transferring torque while maintaining angular correspondence. din 5482 spline standard file type pdf77
): The total count of spline teeth around the circumference. Pitch Diameter (
Primarily for connecting rotating components like shafts and gears to transmit torque.
Several specialised engineering websites host PDF copies of withdrawn standards for reference purposes. The search results consistently point to the following:

When reproducing legacy parts or running structural strength evaluations, raw engineering values must be verified via programmatic calculations. Modern CAD Integration Din 5482 | PDF - Scribd
DIN 5482 was largely superseded by DIN 5480 (which uses a modular reference diameter system) and ISO 4156. However, legacy equipment—especially tractors, old lathes, and German military vehicles—still rely on DIN 5482 dimensions.
While the full PDF standard covers dozens of combinations, certain sizes appear frequently across industrial machinery. Below is a reference snippet of common DIN 5482 dimensions: Designation Number of Teeth ( Major Diameter (Shaft) Minor Diameter (Shaft)
Hobs and broaches designed for DIN 5480 will not cut a DIN 5482 profile because the tooth heights and shifting factors ( ) differ significantly. Geometry and Fundamental Nomenclature This means it is maintained as a reference
DIN 5482 does not itself provide design formulas, but engineers who are working with splines from this standard often need to check the shear stress on the teeth. A common approach used in practice is:
Unlike many modern standards that use a 30° pressure angle, DIN 5482 is distinctive for its specific geometry and historical application: Pressure Angle: Typically utilizes a 30° pressure angle Module System:
Many global hydraulic pump manufacturers (such as Bosch Rexroth, Sauer-Danfoss, and Linde) include comprehensive DIN 5482 dimension tables in their product catalogs. Searching for a hydraulic pump technical appendix PDF often yields the exact tooth geometry and measurement-over-pins data needed for machining. 3. Reverse Engineering with Measurement Over Pins
The DIN 5482 standard remains a critical historical reference for involute splines, though it has been officially and superseded by the more modern DIN 5480 standard . Despite its obsolete status, it is still frequently encountered in the maintenance and repair of legacy equipment, particularly within the hydraulics and fluid power industries. Historical Context and Status
: DIN 5482 bases its entire system layout around the physical fitment dimensions of the shaft diameters. Conversely, DIN 5480 relies on pitch-circle reference diameters that operate entirely independently of the selected module.
