基于车削加工球墨铸铁端盖轴承室表面粗糙度的研究

摘要

球墨铸铁以其优越的显微组织和力学性能,逐步应用于重载装备行业,机车牵引电动机端盖大部分采用该材质.对机车端盖轴承室的表面粗糙度进行了研究,分析了影响端盖表面粗糙度的几何因素和物理因素.采用正交试验法进行试验数据的设置及分析,结果表明,在进行精加工时,小进给量、高转速和适中切削深度能够得到较好的表面质量,满足设计要求.%Nodular cast iron has superior microstructure and mechanical properties,and it is gradually applied in the heavy equipment industry.The end cover of locomotive traction motor most adopts the material.Mainly study the surface roughness of locomotive bearing chamber.Through the orthogonal experiment method set,analyze the experimental data.It is concluded that when the finishing feeding is smaller,the speed is higher.The cutting depth is moderate,so get the good surface quality and meet the requirement of design.
