本文通过组合一般(非垂直)达布运动的不同因式分解，构造了两种类型的7R闭式单环机构。这些因式分解是通过对一般有理运动的因式分解算法进行扩展而得到的。第一类7R连杆机构有几个一维构形部件，其中一个对应于达布运动。另一种是7R连杆机构，有两个自由度，没有一维部件。达布运动是不可约二维构型分量中的一条曲线。
In this paper, we construct two types of 7R closed single loop linkages by combining different factorizations of a general (non-vertical) Darboux motion. These factorizations are obtained by extensions of a factorization algorithm for a generic rational motion. The first type of 7R linkages has several one-dimensional configuration components and one of them corresponds to the Darboux motion. The other type is a 7R linkage with two degrees of freedom and without one-dimensional component. The Darboux motion is a curve in an irreducible two dimensional configuration component.
