论文摘要
我们提出了一个具有两个自由度的闭环8R机制，其运动表现出了好奇的特性。在其配置品种的二维组成部分的任何点上，都可以在保持一个自由度的同时固定每一个关节。这表明均匀轴和奇数轴始终形成贝内特机制。在这种机制中，相反的距离和角度相等，所有偏移均为零。 8R机制具有四种“完全排列”的构型，其中任何一对连续轴的共同正态重合。
We present a closed-loop 8R mechanism with two degrees of freedom whose motion exhibits curious properties. In any point of a two-dimensional component of its configuration variety it is possible to fix every second joint while retaining one degree of freedom. This shows that the even and the odd axes, respectively, always form a Bennett mechanism. In this mechanism, opposite distances and angles are equal and all offsets are zero. The 8R mechanism has four "totally aligned" configurations in which the common normals of any pair of consecutive axes coincide.
