【摘要】 通过对典型的正置空间曲柄摇杆引纬机构的运动学分析，研究了在摇杆最大摆角和输出杆长度取不同的值时输出杆的运动变化规律，选出了能满足传动性能要求的较佳机构参数。同时指出机构尚存在的有待进一步研究的问题。更多还原

【Abstract】 On the basis of the analysis of spatial mechanism of the typical orthogonal crank-rocking lever for the weft insertion in rapier looms, the movement of the outputting level with different maximum swing angle of rocking level and different length of outputting level are studied, and the optimum parameters suitable for motion transmission are ascertained. At the same time requisites for further investigation are mentioned更多还原
