论文部分内容阅读
日本工学博士熊本工业大学相浦正人教授，是当今日本和国际上齿轮加工技术研究的知名学者。多年来，相浦先生已发表论文近３００篇，并拥有多项发明专利。在对切齿过程中硬质合金（或高速钢）刀具磨损和破损机理进行实验研究的基础上，研制出新一代高速防震结构滚齿机、硬质合金滚刀（包括涂层滚刀）、专用切削油等。并在硬质合金滚刀高速及硬齿面滚齿、蜗杆剃滚、蜗杆珩齿、内齿轮加工等方面研究，有很高造诣。应用相浦先生的一系列研究成果，日本大批量生产的汽车行业中、小模数齿轮切齿已实现了自动化、高效率、低成本、低能耗的新水平。此外，矿山及通用机械等行业的大模数齿轮切齿及硬齿面切齿，已实现了较高的加工效率。 相浦先生对我国科技人员怀有友好情谊，曾先后四次来华讲学和进行技术交流。 本刊征得相浦先生同意，拟从本期开始陆续发表他的有关论著。此次刊出的是第一篇文章。本文论述了从硬质合金滚刀的磨损和崩刃发生的条件入手，改进刀具及切削参数，从而提高大模数齿轮加工效率的实验过程，相信对读者会有一定的借鉴意义。
Japanese engineering doctor Kumamoto University of Technology professor Pu Poh-ping is today’s Japanese and international well-known scholar of gear processing technology. Over the years, Mr. Phase Pu has published nearly 300 papers, and has a number of invention patents. Based on the experimental research on the wear-and-tear mechanism of carbide (or high-speed steel) cutting tool in the process of gear cutting, a new generation of high-speed shockproof structure hobbing machine, hard alloy hob (including coating hob), special cutting oil Wait. And in the carbide hob hob and gear hobbing, worm shaving, worm honing, internal gear processing and other aspects of research, a high attainments. Application of a series of research results Mr. phase Pu, Japan mass production of the automotive industry, the small modulus gear hob has achieved automation, high efficiency, low cost, low energy consumption of the new level. In addition, large-modulus gear cutting and hardened gear cutting in mines and general machinery industries have achieved higher processing efficiency. Mr. PHU has a friendly friendship with Chinese scientists and technicians. He has come to China four times to give lectures and conduct technical exchanges. This issue is subject to Mr. Pu agreed, it is proposed from the beginning of this issue one after another published his related treatise. This is the first article published. This article discusses from the carbide hob hobbing and chipping conditions to start, improve the tool and cutting parameters, thereby increasing the efficiency of the large modulus gear machining process, I believe the reader will have some reference.
