The bevel spiral angle factor YBS is calculated for bevel and hypoid gears with a mean spiral angle βm not equal to 0° and accounts for the non-uniform distribution of the tooth root stress along the facewidth as a result of the inclination of the contact lines due to the spiral angle.
For gears with βm = 0°, YBS = 1.
