Sažetak
A computational model for determination of the service life of gears in regard to bending fatigue at gear tooth root is presented. In conventional fatigue models of the gear tooth root it is usual to approximate actual gear load with pulsating force acting in the highest point of the single tooth contact. However, in actual gear operation, the magnitude as well as the position of the force, changes as the gear rotates. A study to determine the effect of moving gear tooth load on the gear service life is performed. The fatigue process leading to tooth breakage is divided into crack initiation and crack propagation period. The critical plane damage model has been used to determine the number of stress cycles required for the fatigue crack initiation. Finite element method and linear elastic fracture mechanics theories are then used for the further simulation of the fatigue crack growth.
