多批量轴承合套快速优选方案的工艺改进

Process Improvement on Rapid Optimization Scheme for Assembly of Multi-Batch Bearings

针对原多批量轴承合套快速优选方案实测游隙与理论游隙存在偏差,尺寸偏差较大的套圈难以合套,计算时间长的问题,提出将匈牙利算法改进为Kuhn-Munkres算法,根据套圈与滚动体的尺寸偏差对其测量数据进行预处理,并引入修正参数对合套游隙进行修正。以某轴承为例的合套结果表明,改进方案减少了计算时间及尺寸偏差较大套圈的累积,提高了合套率。

Aimed at deviation between measured clearance and theoretical clearance,difficult assembly of rings with large size deviation,long calculating time in original rapid optimization scheme for assembly of multi-batch bearings,the Hungarian algorithm is improved to Kuhn-Munkres algorithm,the measured data are preprocessed according to size deviation of rings and rollers,the modified parameters are introduced to correct the assembly clearance.Taking a bearing as an example for assembly,the improved scheme reduces the calculating time and the accumulation of rings with large size deviation,and improves the assembly rate.
