可以連接兩個有角度關係的轉軸，但在使用單組萬向接頭的情況下兩軸會有相位差，若使用兩組萬向接頭加之以兩組的軸偏差角都相同即可使兩轉軸的相位同步。 Two angle-related shafts are joined with one set of universal joints, the two shafts will developed a phase difference, however, if taking advantage of two universal joins and the deviation angle will become the same, enabling synchronism.
