Din 5482 Spline Dimensions Calculator |best| -
Unlike modern spline standards that use a fixed reference module, DIN 5482 relies on a . Key Characteristics Pressure Angle: Always 30 degrees ( 30∘30 raised to the composed with power
A dynamic 2D representation of the spline cross-section. This helps verify correct calculation before cutting a broach or hobbing tool.
A: The choice depends on your primary use case.
Include standard DIN tolerances (such as 9H for hubs and 9g for shafts). Custom Overrides: Allow manual input for profile shifts ( ) for modified legacy gears.
| Symbol | Parameter | Description | | :--- | :--- | :--- | | | Nominal diameter | The reference diameter (e.g., 30 mm). | | z | Number of teeth | Typically 4, 6, 8, 10, or 12. | | b | Tooth width | Width of the tooth on the reference diameter. | | h | Tooth height | Radial height from root to tip. | din 5482 spline dimensions calculator
You might ask: "Can't I just open the old DIN 5482 handbook?"
, it remains widely used for spare parts in industries like fluid flow and hydraulics Key Specifications of DIN 5482 Pressure Angle : Fixed at 30° : Defines the size of the teeth (e.g., 1.6, 1.9, 2.0, 2.1)
The most commonly referenced version is DIN 5482:1950-03 .

): The pitch factor determining tooth size. Common DIN 5482 modules include 1, 1.25, 1.5, 1.75, 2, 2.5, 3, 4, and 5. Number of Teeth (
[ d_fe = d - h ]
The software calculates the exact position where a wire of diameter Dwcap D sub w
standardizes the module and reference diameter strictly, shifting the reference diameter to the pitch diameter.
): For external splines, this can be estimated using the formula:
