摘要

斜齿轮广泛应用于各种机械传动中。因此，分析齿轮接触应力对提高齿轮的疲劳极限和寿命至关重要。本文通过有限元仿真和实验验证对斜齿轮的接触应力进行了分析。在给定摩擦系数的情况下，分析了摩擦系数对斜齿轮接触应力的影响。通过仿真和试验可以得出以下结论:1)啮合初期接触应力随摩擦系数增大而增大。2)啮合后期接触应力随摩擦系数的增大而减小。3)齿轮接触疲劳试验表明，齿面疲劳点的位置与模拟最大应力点的位置一致。齿轮表面的减摩擦涂层可以降低齿面间的摩擦系数，从而有效地提高齿轮的接触疲劳寿命。

Numerical and experimental research of helical gear contact stress considering the influence of friction

Helical gears are widely used in various mechanical transmissions. Thus, analysing gear contact stresses is crucial to improve the fatigue limit and life of gears. In this paper, the contact stress of helical gear is analyzed by finite element simulation and experimental verification. The effect of coefficient of friction on the contact stress of helical gears is analysed, with given coefficients of friction. The following conclusions can be drawn through simulation and test. 1) The contact stress increases with the coefficient of friction in the early stage of meshing. 2) The contact stress decreases with the increase in the coefficient of friction in the late stage of meshing. 3) The gear contact fatigue test shows that the location of fatigue pitting on the tooth surface is consistent with that of the simulated maximum stress point. The friction-reducing coating on the gear surface can decrease the coefficient of friction between the tooth surfaces and thus effectively improve the gear contact fatigue life.
