Unlike some older standards, GOST 19326-73 allows for a more detailed calculation of gears, particularly for non-orthogonal shafts where the shaft angle ( Σcap sigma ) is not equal to 90°.
is an interstate technical standard titled "Spiral bevel gear pairs. Calculation of geometry" . It is currently active and serves as the primary regulatory document for determining the dimensions and geometric parameters of bevel gears with circular (spiral) teeth. Scope and Application gost 19326 73
The standard provides a comprehensive methodology for calculating the geometry of gear pairs, including: Unlike some older standards, GOST 19326-73 allows for
Formulas for calculating the addendum and dedendum heights at various sections (inner, outer, and mean). Unlike some older standards
