Paper Title:
Research on Stress Intensity Factor of Gear Crack and its Variation with Changes of Gear Parameters
  Abstract

Used the theory of linear fracture mechanics and FEM, the two-dimensional model of single-tooth gear is established under the environment of ANSYS. The stress intensity factor(SIF) is analyzed when gear crack occurs and the variation of SIFs is discussed with changes of crack length, gear module, number of teeth, load when gear crack emerges at the pitch circle and tooth root respectively, and the influence of different cracked directions on tooth root is studied; The pragmatic expression of SIFs KI, KII have been brought forth with the results obtained by FEM. These establishes a good foundation on the fracture analysis and diagnosis of gear
