为总结交流、推广应用近几年来圆柱齿轮精加工工艺经验,扩大采用成型磨齿成果,以及落实近年内需开展的齿轮精加工试验研究课题,部科技局责成三○一所,于十一月一日至五日在西安召开了“圆柱齿轮精加工工艺经验交流座谈会”。有七个发动机主机厂参加了会议。会上重点交流座谈了采用成型磨磨齿和NZA蜗杆磨齿机,加工圆柱齿轮中凸齿型工艺。到会代表回顾了一九七五年以来,我部圆柱齿轮精加工工艺的发展过程,认为:几年来各发动机厂,通过新机研制、老机改型,在齿轮精加工工艺方面积累了丰富经验,开发了新工艺,改变了过去只靠MAAG磨精加工的单打一局
In order to summarize the exchange, popularization and application of the experience of finishing technology of cylindrical gears in recent years, expanding the achievements of forming grinding and grinding teeth, as well as carrying out experimental research on gear finishing carried out in recent years, the Ministry of Science and Technology has assigned 301 to one, Day to the 5th held in Xi’an, “cylindrical gear finishing process exchange experience-sharing seminar.” Seven engine OEMs attended the meeting. The meeting focused on the exchange of discussion using the grinding gear and NZA worm gear grinding machine, processing cylindrical gear in the tooth-type process. Delegates to the meeting reviewed the development of the cylindrical gear finishing process of our department since 1975 and concluded that: In recent years, various engine factories have accumulated rich experience in gear finishing through new machine development and modification of old machines. Experience has led to the development of new processes that have changed the history of singles in the past with MAAG finishing alone
