| 摘 要： | 圆柱滚子是轴承的重要组件,随着对设备仪器性能的要求不断提高,对圆柱滚子的精度和一致性要求也越来越高。文章分析行星式双平面研磨方式下磨料粒度、研磨盘转速、夹具孔偏角对圆柱滚子的加工精度的影响情况。文中首先基于正交实验设计了标准的L9(34)正交表,并严格按照正交表中的实验序号进行了圆柱滚子的加工实验,然后采用信噪比和ANOVA方差法对加工结果进行数据分析,最终获得了参数的最优组合。根据优化的研磨条件进行加工,结果显示圆柱滚子的圆度、直线度以及平行度均达到了1μm以下,优化效果显著。

| Abstract: | The rolling element is the most important component of rolling bearings. Its geometric accuracy and consistency affects the performance and working life of bearings greatly. A standard taguchi L9 （3^4） orthogonal array （oa） was designed to analyze abrasive size, rotating speed of plates, deflection angle of carrier holes and other factors impacting on precision of cylindrical roller process and achieved the optimized parameters combination by adopting evaluation of signal-to-noise ratio and ANOVA analysis （ analysis of variance）. Under the optimized lapping condition, the better roundness, straightness and the parallelism of the cylindrical roller was achieved. |
