中文摘要：

分析了一种具有两个自由度的双驱动行星式光纤连接器端面研磨装置的运动原理，并求解出光纤连接器在研磨时相对于研磨盘（研磨砂纸）的运动轨迹。通过引入定义“速比”，建立了研磨装置两个独立主动件之间的转速关系。针对光纤连接器研磨中存在的问题，从速比入手，以运动轨迹曲线、研磨运动路程偏差、切削速度、速度周期变换系数为纽带，将研磨运动、研磨工艺以及研磨质量联系起来，得出了一组优化的光纤连接器研磨装置的运动参数。当系杆的转速设定为132r／min时，根据粗、精研磨不同的工艺要求，其内齿轮的转速应在31～54r／min调整。此时，速度周期变换系数小于2．2;运动路程偏差小于0．5％；研磨运动轨迹密集而不重复。实验证明了分析结果的正确。

英文摘要：

The motion principle of a two-motor driven lapping machine with an epicyclic gear and 2 degrees of freedom for Optical Fiber Connectors （OFC） was analyzed. The lapping motive path of OFC relative to lapping tool （lapping film） was also figured out. The rotating speed relationship between two independent driving components of lapping machine was established by introducing the definition on ＂velocity ratio＂. In order to solve the problems existing duration of lapping OFC, considering the velocity ratio and building relationship of lapping motion, lapping process and lapping quality, the optimal results of motion parameters of lapping machine for OFC were obtained with the aid of lapping motive path curves, lapping distance difference, cutting velocity and transform coefficient of velocity cycle. When rotating speed of the tie bar is 132 r/min, according to coarse or fine lapping processes, the rotating speed of the ring gear should be between 31～54 r/min. Here, the transform coefficients of velocity cycle and lapping distance differences are less than 2.2 and 0.5% ,respectively, lapping motive paths are very dense and not overlapped. The analyzing results are proved by experimental resuits.
