| 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

To determine the fit and tolerance for a DIN 5482 spline, an engineer must calculate: Selection between a Shaft (External) or Bore (Internal)

For an external spline, the calculator will: | | b | Tooth width | Width

The arc length or chordal distance of a tooth at the pitch circle.
