机械变形在机械传动中一般说来有很大的害处，但是，有时巧妙地利用机械变形可以收到意想不到的效果。下面是我们在试验LWB（Ⅱ）型菱形网编织机时遇到的一个实例，如图1所示。B点是成形的网丝，需要由剪刀10剪断。如果剪不断不能进行下一个工作程序。在整个剪切系统当中，没有 Mechanical deformation is generally very harmful in mechanical transmission, however, sometimes unexpectedly effective mechanical deformation can be received unexpectedly. The following is an example of what we encountered when testing a LWB (II) diamond mesh weaving machine, as shown in Figure 1. Point B is a formed mesh that needs to be cut by the scissors 10. If the cut can not continue the next working procedure. Among the entire shearing system, no
