A computational model for determining the service life of gears with regard to bending fatigue in a gear-tooth root is presented. The fatigue process leading to tooth breakage is divided into the crack-initiation and crack-propagation periods. The Coffin-Manson relationship is used to determine the number of stress cycles, Ni , required for the fatigue crack initiation, where it is assumed that the initial crack is located at the point of the largest stresses in a gear-tooth root. The simple Paris equation is then used for the further simulation of the fatigue crack growth, where the required material parameters have been determined previously with appropriate test specimens. The functional relationship between the stress-intensity factor and the crack length, K=f(a), which is needed for determining the required number of loading cycles, Np , for a crack propagation from the initial to the critical length, is obtained numerically in the framework of the finite-element method. The total number of stress cycles, N, for the final failure to occur is then a sum N = Ni +Np . Although some influences (non-homogeneous material, travelling of dislocations, etc.) were not taken into account in the computational simulations, the presented model seems to be very suitable for determining the service life of gears because the numerical procedures used here are much faster and cheaper than experimental testing.
