论文部分内容阅读
本文为“齿轮制造技术基础”的第二部份,主要介绍美国齿轮滚刀材料。其中关于“在一般情况下首先应选用M—2高速钢,和M—42超高速钢齿轮滚刀主要用于加工HRC38—42淬硬齿轮”的结论,望读者切勿忽视。一机部工具研究所在先后二个课题中,对13,000余件20CrMnTi正火齿轮切削试验的结论,基本上与其相符。文中多头齿轮滚刀一节对齿轮齿致与齿轮滚刀头数的关系的论述,有一些不常见的论点。最后文中关于防止齿轮滚刀破损,报导了美国现用的方法,可供国内有些厂中常见的齿轮滚刀破裂问题提供解决方案。为使读者阅读便利,我们还将文中引用的美国、瑞典高速钢牌号的化学成份列表于后。治金部代表团访问瑞典Uddeholm钢厂时,该厂说粉末高速钢大多销美国。与此文报导相符,此文对美国齿轮滚刀材料的叙述,可认为是正确的。
This article is the second part of “Gear Manufacturing Technology Foundation”, mainly introduces the gear hobbing material in the United States. Among them, the reader should not neglect the conclusion that “M-2 high-speed steel should first be used in general and M-42 high-speed steel gear hob should be mainly used for processing HRC38-42 hardened gear”. A machine tool research institute has two topics in succession, more than 13,000 pieces of 20CrMnTi normalizing gear cutting test results are basically consistent with them. The article on the relationship between the gear tooth induced and the gear hob head in the section of the multi-headed gear hob has some uncommon arguments. The last article on the prevention of gear hob damage, reported the United States is currently using the method available for some domestic plant gear hobbing problems common to provide solutions. For the reader’s convenience, we also list the chemical composition of high-speed steel grades from the United States and Sweden quoted in the text. When a delegation from the Kimdi Department visited Uddeholm Steelworks in Sweden, the plant said most of the powdery HSS was sold to the United States. In line with this article reported, this article describes the gear hobbing material in the United States can be considered correct.
