Analysis on Contact Stress after Gear Meshing and Finite Element of Stiffness

摘要

According to APDL language of ANSYS, this paper establishes the ideal identity model of tooth profile and gear based on ideal tooth profile equation, and it gets the ideal gear profile in meshing period and change curve of maximum contact stress with position of gear meshing. The result indicates that the contract stress distribution of ideal gear profile presents certain regularity with meshing state of double gear. Gear module can not change the stiffness value of gear meshing; increasing the number of driving wheel can reduce meshing stiffness. Finally, this paper gets the curve of meshing stiffness changes with load. The result indicates that the effect of load on deviation and tooth profile and gear meshing is larger than that on idea tooth profile and stiffness of gear meshing.
