Stress Correction in Spur Tooth Root

The state of stress in spur tooth root is determined by means of the three-diomensional finite element method. The calculations are performed for the gears loaded by uniform load distribution along the tooth tip, varying the gear teeth number, the rim thickness and the tooth facewidth. On the basis of computed maximum tensile and equvalent Von Mises root stresses, the stress correction factors are defined in relation to the standards DIN 3990/ISO 6336, to underline the difference refering to usual two-dimensional approach for spur gear analysis.
