图示为一种新型万向联轴器的结构。件2和件1是左右两个半万向节,它们是在一根钢管上由一条封闭曲线切出的两个部分,详见展开图。在件2和件1的切口处,其曲线的凸凹部分一一对应,并制有一定间隙。同时,件2件1相对应的凸凹部分曲线又互相镶 The figure shows the structure of a new universal coupling. Pieces 2 and 1 are left and right half-joints, which are two sections cut from a closed curve on a steel pipe, as shown in the expanded view. In the two pieces and pieces 1 of the incision, the curve of the convex part of the corresponding one by one, and made a certain gap. At the same time, pieces of 2 corresponding to the convex and concave part of the curve of another set
