Analysis of methods for calculating tooth interior fatigue fracture

Abstract

The tooth interior fatigue fracture is an important criterion for the performance of a gear. The article analyzes the existing methods for determining the tooth interior fatigue fracture of cylindrical gears. Methods (Findley, V. I. Korotkina, E. I. Tesker and V. N. Syzrantsev) are validated on the basis of available experimental data. The results are presented in the form of graphs of changes in the safety factor for the depth of a case and a summary table of calculations and experimental results.
