摘要
针对相同啮合齿宽,对比分析了基于国标计算公式、Romax软件全齿啮合和Romax软件错齿啮合3种方法计算而得的接触应力和弯曲应力结果,进而研究了不同啮合齿宽(即不同错齿量)对齿轮弯曲应力值的影响。同时采用罗卡提快速疲劳试验方法,进行运转式齿轮弯曲疲劳试验,通过3种方法确定各级载荷的弯曲应力值,从而分别获得相应的弯曲疲劳极限估计值。通过对比弯曲疲劳极限估计值,确定了基于Romax软件错齿啮合计算错齿啮合弯曲应力的可信性,为错齿啮合齿轮弯曲应力的计算提供参考方法。
The contact stress and bending stress are calculated and comparatively analyzed with me same meshing tooth width by using three methods of the national standard formula based, Romax software （full tooth meshing） and Romax software （ staggering tooth meshing） , and thus the effects of different meshing tooth width （ that is different staggering tooth amount） on the gear bending stress values are researched. While by using Lo- cati rapid fatigue testing methods, the operating gear bending fatigue tests are carried out and the bending stress of each load with three methods are determined, the bending fatigue limit estimated values are obtained. By comparing the bending fatigue limit estimated value, the bending stress credibility of staggering tooth meshing is determined based on Romax software （staggering tooth meshing）, the reference method for the gear bending stresses calculated with staggering tooth meshing is provided.
