摘　　要：利用不完全齿轮机构的特点,设计一种齿轮式自动换向装置,实现输入轴连续单向转动,输出轴连续正反向转动,且保持输入轴的转速和输出轴的转速之比为定值。分析了不完全齿轮首齿和末齿的啮合线长度,在保证重合度等于1时,运用齿顶高修形法,避免了不完全齿轮传动的干涉现象发生。By the characteristics of the incomplete gear mechanism,a kind of gear automatic reversing device to realize the input shaft continuous unidirectional turns is designed to realize,the output shaft positive and negative rotary under the condition of the input shaft speed and output speed ratio is fixed value.The length of line of action with the teeth at the end and the first of incomplete gear is analyzed,on the premise of contact ratio equal to one,using repair form method of addendum,the interference phenomenon of the incomplete gear transmission is avoided.
