摘　　要：采用四齿差双波谐波齿轮传动的主要目的是为了在小传动比情况下不致影响柔轮的强度 ,本文主要研究其精度特征。通过对四齿差谐波齿轮传动与其对应的二齿差谐波齿轮传动的啮合包角进行计算 ,在工程上实用的误差评估公式的基础上 ,得出四齿差谐波齿轮传动运动精度比二齿差谐波齿轮传动提高百分之十以上的结论。利用研制的样机进行运动精度对比实验 ,实验结果与理论预测有较好的一致性 。The primary purpose of developing the four-tooth difference (FTD) harmonic drive is to decrease the stress in flexspline under the condition of smaller transmission ratio. In this paper, we focused our study on its accuracy characteristics. By calculating the engagement wrapping angle of FTD harmonic drive and its corresponding two-tooth difference(TTD) harmonic drive, based on the practical accuracy evaluation formula in engineering, we have drawn the conclusion that the transmission accuracy of FTD harmonic drive increases more than ten percent of its corresponding TTD harmonic drive. The accuracy comparison experiment by prototype shows that experimental results and theoretical predication are in agreement, it can be used in the manufacturing of high precision engineering appliance of FTD harmonic drive.
