Sažetak
A computational model for determination of service life of gears in regard to bending fatigue in a gear tooth root is presented. The fatigue process leading to tooth breakage is divided into crack initiation and crack propagation period. The Coffin-Manson relationship is used to determine the number of cycles required for the fatigue crack initiation. The Paris equation is used for the further simulation of the fatigue crack growth. The total number of stress cycles for the final failure to occur is a sum of stress cycles required for the fatigue crack initiation and number of loading cycles for a crack propagation from initial to the critical length.
