摘要
以蜗式凸轮分度机构的分反误差计算公式作为主要依据，首先对分度误差进行了优化，使优化前后的分度误差改善近３０％；进而又对影响分度误差的若干因素进行了分析，所得出的结论对蜗式凸轮机构的设计具有一定的参考价值。
Based on the formula of index error calculation of worm-type cam,an improvement of nearly 30% on index error is first made by optimizing the index error.Secondly a conclusion which has some reference value for the design of worm-type cam is drawn by analysizing the factors affecting the index error.
