摘　　要：为提高航空发动机主轴轴承用钢制保持架的加工精度和表面质量,以某圆柱滚子轴承保持架为例,对其加工性能进行分析,结合保持架的精度要求制订了加工工艺方案。实例检测数据表明:除梁宽变动量Vbcs外,其余精度均远远高于产品要求的精度,尤其是V_(Ss),V_(s1)和K_(cs)控制得非常理想。In order to improve the machining accuracy and surface quality of steel cages for mainshaft bearings of aero- engine,taking the cages of tapered roller bearings as an example,the machining performance is analyzed. The processing schemes are formulated combining with accuracy requirements for cages. The actual measured data show that the accuracy of finished cages is far above accuracy requirementt,especially for control of VSs,Vs1 and Kcs,except for the variation of beam width Vbcs.
