对于推力向心球面滚子轴承实体保持架中心径的测量,目前常用的方法如图一所示:做两个双锥体的塞子(对圆锥形兜孔而言),分别插到保持架的两个相距最远的兜孔中,使其上部锥体的一根母线AB(及A′B′)正好处于铅直位置,然后用卡尺测量AB和A′B′间的距离,通过换算,求出保持架的中心径 Pc。但仔细分析,会发现这种测量方法尚存在如下一些问题: 1.对于圆锥形兜孔保持架(图一a),由于兜孔直径存在着制造公差(一般又较大),使塞子沿兜孔轴线向下位移,从而造成较大
For the thrust radial spherical roller bearing solid cage center diameter measurement, the commonly used method is shown in Figure 1: Do two double cone plug (for the conical pocket), were inserted into the cage The two farthest pockets, so that the upper cone of a bus AB (and A’B ’) is located in the vertical position, and then use the caliper to measure the distance between AB and A’B’, by conversion, The cage center diameter Pc is determined. However, careful analysis, you will find this measurement methods are still some of the following problems: 1. For the conical pocket cage (Figure a), due to pocket diameter manufacturing tolerances (generally larger), so that the stopper along the pocket Hole axis downward displacement, resulting in larger
