摘　　要：测量特大型圆锥滚子轴承用筐形保持架小端外径时,样板测量结果精度不够,三坐标测量成本较高且效率低。针对特大型圆锥滚子轴承用筐形保持架的结构特点,综合分析后提出了采用光栅尺和标准测量杆间接测量保持架小端外径尺寸的新方法。与三坐标测量仪的对比表明,该测量方法可精确获取保持架小端外径尺寸。For measurement of outer diameter at small end of basket-shaped cages for extra-large size tapered roller bearings,the measurement results are not accurate enough when using template,and the cost of three-coordinate measurement is high and the efficiency is low.In view of structural characteristics of basket-shaped cages for extra-large size tapered roller bearings,a new method is proposed for indirectly measuring outer diameter at small end of the cages using a grating ruler and a standard measuring rod after comprehensive analysis.The comparison with three-coordinate measuring machine shows that the measuring method can accurately obtain outer diameter at small end of the cages.
