WebMar 24, 2024 · Gear teeth are subject to two different types of stresses: root bending stress and tooth contact stress. Gear teeth break under these two stresses.: contact stress cause pitting failure at the contact surface, and root bending stress causes fatigue fracture. Thus, while constructing gears, both of these strains must be taken into account. Typically, … WebMar 27, 2024 · Gear is a reliable part of power transmission. This article presents a metallurgical failure analysis of a failed gear used in automobile engine coolant pumps.
