看到本刊第三卷第六期中长东同志的“几种制造人字齿轮方法的建议”一文,对于专门制造人字齿轮的工作母机一方面,没有详细的介绍其机构及动作,而这种专门切削人字齿轮的工作母机,在我们今后机械工业的发展上是有着重要的地位;所以我们在这里介绍一种专门切削人字齿轮的,但是只限于用齿条刀的半自动人字齿轮铇床,如〔图二〕所示。其内部机构传动图期如〔图一〕。
Seeing the article “Several Suggestions for Manufacturing the Herringbone Gear Method” by Comrade Zhong Changdong of the third issue of the third issue of this volume, the working machine that specializes in the manufacture of herringbone gear does not have a detailed introduction of its mechanism and action. The special working machine for cutting herringbone gear has an important position in the development of our machinery industry in the future; therefore, we introduce a special cutting herringbone gear here, but it is limited to a semi-automatic herringbone gear with a rack cutter. Trampoline, as shown in Figure II. Its internal mechanism transmission schedule is as shown in Figure 1.
