双列角接触球轴承合套时,常常出现部分成品装配高达不到技术要求或中间垫尺寸留量不合适而使游隙不能满足技术要求的情况,需经过反复配套和修磨才能组配出合格成品.经分析,主要原因是成品零件公差要求较宽,改进的方法是根据成品零件标准压缩加工尺寸公差,提高了合套率,降低了劳动强度.

@@@@During the set fitting of double row angular contact ball bearing, the common problem is that the clearance can not meet the technical requirements, because the cross corner of some finished product didn’t meet the requirement or the allowance for intermediate washer is not suitable. In order to couple a finished part, it’s necessary to grind and set fit again and again. Through analyzing, the main cause is the tolerance range of finished part is wide. By reducing the tolerance based on finished part standard. the set fitting rate is increased and the labour intensity is reduced.
