摘　　要：从合套率与内、外圈沟径加工工序能力指数的关系角度 ,探讨微型深沟球轴承的合套率的优化问题。首先简要推导出计算深沟球轴承的理论合套率的公式 ,然后以 6 0 8系列微型轴承为例 ,计算套圈沟径的工序能力指数和钢球组数在不同组合条件下的理论合套率 ,对合套率数据进行分析 ,找出影响合套率的主要因素 ,提出改进措施。From the relation of fitting rate to working procedure ability exponent of the inner race and the outer race, the optimization of fitting of the miniature deep groove ball bearing is researched, the theory formulas to calculate the fitting rate for deep groove ball bearing is inferred. For the example of 608 series miniature bearings, the theory fitting rate is calculated in the different composition of working procedure ability exponent of the race groove diameter with steel ball group number. The analysis on the fitting rate data is made, the main factors to affect fitting rate are found, and the improvement countermeasure is put forward.
