摘　　要：针对推力球轴承套圈沟道中心径测量时存在准确率低,重复性及通用性差,受人为因素影响较大等问题,根据推力球轴承套圈的结构特点,提出了定量测量沟道中心径的轮廓仪测量法和三坐标测量法,并详细阐述了2种新方法的测量原理,测量步骤及优缺点。2种尺寸套圈的测量结果表明,三坐标测量法的效果最好,轮廓仪测量法的效果次之,均优于常规三球法。在实际测量中,可根据测量需求合理选择测量方法。Aimed at the problems in measurement of ring raceway central diameter of thrust ball bearings, such as low accuracy, poor repeatability and universality, great influence from artificial factors, etc., according to structural characteristics of the rings, the profilometer measuring method and coordinate measuring method are proposed to quantitatively measure the raceway central diameter, and the measuring principle, measuring steps and advantages and disadvantages of two new methods are described in detail. The measuring results of the rings with two sizes show that the effect of coordinate measuring method is the best, the effect of profilometer measuring method is the second, and the effects of two new measuring methods are better than conventional three ball measuring method. During actual measurement, the measuring method is selected reasonably according to measuring demand.
