摘要
推导了余弦齿轮传动的重合度计算公式,进一步讨论了余弦齿轮传动重合度随齿数、模数、分度圆压力角等参数的变化规律,并与渐开线齿轮传动进行了对比．结果表明,余弦齿轮传动的重合度随齿数、模数的增加而增大,随着压力角的增加而减小．在相同的设计参数下,余弦齿轮传动的重合度明显大于渐开线齿轮传动．图5,参12．
Based on the mathematical models of the cosine gear drive, the calculation approach of the contact ratio of the drive was deduced,and the influences of related design parameters on the contact ratio were discussed. The results show that the contact ratio of the cosine gear drive increases with the increase of the teeth number and the modulus, but decreases with the increase of the pressure angle of the pitch circle, under the same parameters condition, the contact ratio of the drive is obvious greater than that of the involute gear drive. 5figs., 12refs.
