摘要
汽车主减速器装配质量的影响因素很多,其中一个重要的因素是如何选取垫片厚度的问题。文章采用有限元法对某商务车后桥主减速器装配过程进行力学分析,获得了主减速器装配过程中的变形和应力状态;针对主减速器工作中应满足最小驱动力矩的指标,通过数值计算得到垫片实际的厚度,为主减速器的一次性装配成功提供了依据。
Determination of the gasket thickness is an important factor which influences the assembly quality of the final drive. In this paper, the finite element method is applied to the analysis of the stress and displacement fields of the final drive in the process of assembling. The suitable thickness of the gasket is gained through numerical calculation as the least driving moment which makes the final drive run easily meets the requirement of the assembly.
