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