摘　　要：针对关节轴承外球面抛光加工开展新工艺研究。通过采用锥度芯轴胀紧的定位方式,以及开设储存碳化硼抛光剂的油石,在车床上进行关节轴承的外球面抛光。改进后的抛光工艺可显著提高关节轴承外球面的加工质量,降低粗糙度值Ra,保证球面圆度,并大大提高生产效率。A new polishing process is developed for the polishing of the outer spherical surface of spherical plain bearing.The outer spherical surface of spherical plain bearing is polished on the lathe by using the positioning method of taper mandrel expansion and setting up oilstone for storing boron carbide polishing agent The improved polishing process can significantly improve the processing quality of the outer spherical surface of the joint bearing,reduce the roughness Ra,ensure the spherical roundness,and greatly improve the production efficiency.
