Calculation of the contact line of helical gear and the finite element anaylsis of the bending strength

Sun Zhijin;Qiao Yingmin;Shaanxi Fast Gear Co.Ltd;  
This paper solves the problem of the helical gear meshing contact line projecting to the tooth surface, successfully draws the contact line in three-dimensional model of helical gear at any time, and chooses the worst meshing moment doing finite element analysis, the bending strength is calculated using empirical formula of ISO 6336 standard and compared with the rusults of finite element analysis, the gear bending stress is basically the same, which verify the correctness of the calculation.
