摘　　要：针对原大型圆柱滚子轴承铜保持架机加工工艺材料利用率低,加工质量低,生产效率低,加工成本高的问题,提出一种保持架冲压加工工艺:落料→成形拉深→车端面→冲孔→压坡→磷化,同时改进保持架兜孔形状,使滚子与窗梁之间为四点或四线接触,保持架加工新工艺加工质量稳定,装配试验后轴承运转无异常,说明大型圆柱滚子轴承可采用冲压保持架代替机加工铜保持架。Aimed at the problems of low material utilization rate,low processing quality,low production efficiency and high processing cost in original process for large size cylindrical roller bearing copper cages,a stamping process is proposed for the cages:blanking→forming and drawing→turning of end face→punching→slope pressing→phosphating.At the same time,the shape of the cage pockets is modified to provide the four point or four line contact between rollers and window beams.The cages processed by new processes have stable processing quality,no abnormality during operation of the bearings after assembly test,indicating that stamped cages can be used to replace machined copper cages for large size cylindrical roller bearings.
