By considering factors of load distribution among gear teeth during the course of gear engagement , through carrying out interpolating correction on the journey of primitive loading of gear and rain flow count and utilizing the method of 3d finite element analysis , the influence of prediction on bending fatigue life of gear affected by load distribution among gear teeth has been probed 摘要考慮齒輪嚙合過程中齒間載荷分布的因素,通過對齒輪原始載荷歷程進行插值修正和雨流計數(shù),運用三維有限元分析方法,探究了齒間載荷分布對齒輪彎曲疲勞壽命預測的影響。
