对大量实测数据进行数理统计运算后,得出下列结论:①反映沟道形状误差变化趋势的新参数——最大斜率S_M是影响轴承振动值的主要因素;②在不提高轴承精度的条件下,利用内、外圈和钢球的互补作用,通过合理选配备零件的S_M值,也可降低振动值;③外圈对振动的影响比内圈大一倍,因此外圈外径应超精研.附表1个 After a large number of measured data were calculated by mathematical statistics, the following conclusions were drawn: ① The new parameter that reflects the trend of channel shape error - the maximum slope S_M is the main factor affecting bearing vibration; ② Without increasing the bearing accuracy, The use of the inner and outer rings and steel ball complement each other through a reasonable choice of spare parts S_M value, but also reduce the vibration value; ③ outer ring on the vibration than the inner ring twice, so the outer diameter should be ultra-precision.
