Sažetak
A numerical model, based on the finite element and the strain-life methods, is proposed to estimate tooth bending fatigue life of case- carburized steel spur gear from number of cycles required to initiate surface fatigue crack at the tooth root fillet. The fatigue life estimates were found to correlate very well with the available experimental lives from pulsator testing. The model is used then to correlate fatigue life estimates for two load cases: the first one in which the gear tooth is loaded with pulsating load acting at the outer point of single pair tooth contact, and the second one in which quasi-static meshing of the gears is considered.
