Standardized symbols and terms used in design documentation and engineering software like SolidWorks or T-FLEX CAD . Context within Gear Standards
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
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°. gost 19326 73
Covers the geometry calculation for straight bevel gears.
The standard provides a comprehensive methodology for calculating the geometry of gear pairs, including: Standardized symbols and terms used in design documentation
Defines the initial contour for bevel gears with circular teeth.
Formulas for calculating the addendum and dedendum heights at various sections (inner, outer, and mean). It is currently active and serves as the
Calculations for the pitch cone, face cone, and root cone.
