齿轮传动弯曲疲劳强度的可靠性分析

Reliability analysis of bending fafigue strength for gear drive

考虑起重机用齿轮传动中的各齿轮失效间相关定量程度，运用失效模式相关时的机械系统可靠度的计算方法，对齿轮传动系统弯曲疲劳强度的可靠度进行计算，并给出一实际算例。

With consideration of quantitive correlativity among gear failure modes of cranes gear drive and application of reliability calculation method of mechanical system in failure mode correlation,this paper calculates the reliability of bending fatigue strength for gear drive system and gives an example.
