Abstract

The problems of improving the accuracy of the definition of resistance to corrosive fatigue of the shafts of transmission gears, which operate under the effect of atmospheric precipitation and under variable complex loading (joint cyclical bend and torsion), were considered. According to the results of fatigue tests, the equations of the families of fatigue lines for the probability interval of no-failure P(N) = 50–99.9% were derived. The dependences to determining the coefficients of strength and durability in a wide interval of multicycle fatigue are obtained. The nomogram of these coefficients for a probabilistic estimate of the carrying capacity of the shafts at N = 10⁵–10⁸ cycles is given.

通过耐腐蚀强度准则提高车辆结构元件的承载能力

摘要

考虑了提高在大气降水的作用下以及在可变的复杂载荷（联合循环弯曲和扭转）下工作的传动齿轮轴的耐腐蚀疲劳的定义的精度的问题。根据疲劳试验的结果，推导了无故障概率区间P（N）= 50–99.9％的疲劳线族方程。获得了在宽范围的多周期疲劳中确定强度和耐久性系数的依赖性。给出了这些系数的诺模图，以便概率估计N = 10 ⁵ –10 ⁸循环时的轴的承载能力。
