外滚道精度直接影响圆锥轴承的使用性能和工作寿命,而且外滚道磨削属内表面磨削,效率低,耗能大。影响其几何精度的因素很多,用正交试验可方便地找出其规律性,从而合理地解决问题。一、正交试验试验因素见表1。 The accuracy of the outer raceway directly affects the performance and working life of the tapered bearing, and the outer raceway grinding belongs to the inner surface grinding, low efficiency, large energy consumption. Many factors affect its geometric accuracy, using orthogonal test can easily find out its regularity, so as to reasonably solve the problem. First, the orthogonal test factors in Table 1.
