一、问题的提出 2K—H周转轮系,可以固定其中一个中心轮,实现行星传动。这时,运动可以从一个中心轮输入,转臂输出;也可以反过来。若三个基本构件都不固定,便形成了差动轮系。这时,运动可以从其中一个基本构件输入,另外两个基本构件输出;或从其中两个基本构件输入,余下的一个基本构件输出。现在有一个问题:是 First, the issue raised 2K-H epicyclic gear, one of the center wheel can be fixed to achieve planetary transmission. At this time, the exercise can be input from a central wheel, jib output; can also be reversed. If the three basic components are not fixed, they formed a differential gear train. At this point, the movement can be input from one of the basic components, the other two basic components output; or from two of the basic components input, the remaining one of the basic components output. Now there is a question: yes
