摘　　要：研究了输入输出均为旋转运动且两旋转轴不共面(也不垂直)的情况下连杆机构的结构设计。提出了3种方案:1)直接用1根连杆连接输入输出,形成RSSR结构;2)用1根任意方向的中间轴和2根连杆将输入输出连接起来,形成双RSSR机构;3)与方案2类似,不同的是中间轴与输入输出旋转轴均垂直。通过分析3种结构方案机构运动计算机模拟结果可知,方案3不仅在结构布局上具有一定的灵活性,而且更有利于保持输入输出运动间的线性关系。Design of a linkage mechanism was studied,whose input and output are all rotation but around two un-coplanar axis respectively.Three plans of construction were made out and discussed.The one is a kind of RSSR mechanism which was formed by connecting the input and the output directly with a linkage.The other was a kind of dual-RSSR mechanism formed by connecting the input and the output with some middle parts.The third was also a kind of dual-RSSR mechanism but the axis of a middle part in it is perpendicular simultaneously to the input rotary axis and the output one.Computer kinematic simulation conducted to these three mechanisms leads to the following conclusions：the third plan is flexible enough to layout and can obtain linear relationship between its input and output more easily than other two plans do.
