汽车后桥差速器齿轮结构设计优化研究

Study on the Optimal Design of the Straight Bevel Gear in Differential Case

提出将差速器圆锥齿轮的结构设计与性能设计结合起来,分两个阶段运用CAE技术对其受载情况进行分析计算和优化研究,主要改善了汽车后桥差速器圆锥齿轮设计方案中应力集中、应力不合理分布与扩展的状况,提高了基体的承载能力,减少了断裂失效的预期,优化了产品的结构设计。

Performance analysis is integrated into the design of the straight bevel gear in differential case.The carrying capacity of gear is analyzed and its design is optimized into two successive phases.First,the stress concentration area is found,and the unreasonable expanding mechanism is corrected.Second,the design of bevel gear is optimized to improve load the capacity of base.Then the fracture failure rate would be cut down.
