摘　　要：研究考虑误差因素时的内平动齿轮传动齿廓重叠干涉限制条件.通过对中心距误差、齿厚偏差、齿距偏差、齿廓偏差等误差的分析,得到齿轮的各种误差对传动转角以及啮合角的影响.结合齿廓重叠干涉的定义,得到误差因素对齿廓重叠干涉的影响.结果表明,正的中心距误差与齿厚偏差使[Gs](齿廓重叠干涉限制条件最小许用值)减小,负的中心距误差、齿距偏差以及齿廓偏差使[Gs]增大.实验表明,根据本文中公式设计出的内平动齿轮传动齿轮副,不会发生齿廓重叠干涉.After analyzing synthetically all kinds of deviation of tooth thickness, deviation of pitch and error factors such as center distance error, deviation of profile, the effect of these errors on the transmission angle and meshing angle are found, and finally the effect of errors on profile overlap interference found. It is demonstrated that [Gs] value, or the allowable value of profile overlap interference constraint condition, will decrease when the center distance error is plus, or the deviation of tooth thickness exist, and will increase when the center distance error is minus, i. e. ,a deviation of pitch or of profile exists. It was proved in experimentation that profile overlap interference will not occur, if the gear pair of internal parallel move gear transmission is designed according to requirements given in this paper.
