汽车后桥差速器齿轮结构优化
|
摘要
针对汽车后桥差速器圆锥齿轮存在表面应力复杂、承受载荷大的情况,首先以某型汽车后桥差速器齿轮作为研究对象,借助UG平台建立三维实体模型并进行有限元分析,提出第一阶段的9个单项改进方案和3个综合优化改进方案;然后结合轮齿仍然存在的失效形式,给出第二阶段的结构优化设计方案。实例计算表明,该方法较大程度提高了半轴齿轮和行星齿轮的承载能力。
Absrtact: To solve the problems of circular bevel gear of a rear axle differential such as complex surface stress and heavy load,the paper centers around the rear axle differential of certain automobile,utilizes UG platform to establish a three-dimensional solid model and make finite element analysis,puts forward nine single improvement schemes and three integrated optimization schemes in the first stage,and gives a structural optimization design scheme of the second phase in combination with failure forms of the gear teeth. The examples show that this method can improve the load-carrying capability of the half shaft gear and planetary gear.
