摘要
摆线齿轮是摆线针轮行星传动的关键零件，针对国内生产现状，提出了三坐标测量机和工具显微镜进行摆线轮误差的测量，两者均可反映整个台廓的齿形误差，对提高摆线轮的加工精度提供了理论保障。
Cycloid gear is the key part cycloid of planet transmission. To be dead against domestic current situation, put forward some new method of measure cycloid tooth error by three coordinate measuring mechine and instrument microscope. Both can find cycloidtooth error in the all and the one. To provide theory ensure for improve machining precisionof cycloid gear.
