Gost - 19326 73

GOST 19326-73 is part of a broader suite of Soviet and Interstate standards for gear design, often used alongside:

Standardized symbols and terms used in design documentation and engineering software like SolidWorks or T-FLEX CAD . Context within Gear Standards

Calculations for the pitch cone, face cone, and root cone. gost 19326 73

This standard applies specifically to with external meshing under the following conditions: Shaft Angles: Between 10° and 150°. Spiral (Helix) Angles: From 0° to 45°. Basic Profile: Straight-line profile of the basic rack. Key Content

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 is part of a broader suite

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°.

Covers the geometry calculation for straight bevel gears. Spiral (Helix) Angles: From 0° to 45°

Formulas for calculating the addendum and dedendum heights at various sections (inner, outer, and mean).
