一、引言随着科学技术的不断发展,大模数、大直径、大宽度、硬齿面齿轮在各种生产、科技领域中得到愈来愈广泛的应用。因此1988～1990年,我们承担了省级科研项目——“叠片式蜗杆型密排列强迫剃齿刀”的研制任务,该刀具已于89年11月初步成功地应用于生产实践中。该刀具于1990年6月通过了省科委组织的科技成果鉴定。经鉴定委员会专家评议,一致认为:“在我国齿轮加工行业从软齿面向硬齿面过渡的过程中,该项成果开创了一条适合我国国情的齿
I. INTRODUCTION With the continuous development of science and technology, large modulus, large diameter, large width, hardened gear in a variety of production, science and technology has been more and more widely used. Therefore, from 1988 to 1990, we undertook the research and development task of a provincial-level scientific research project, “Stacked Worm-type Forced Formations Shaving Cutter”, which was initially successfully applied to production practice in November 1989. The knife in June 1990 passed the scientific and technological achievements organized by the Provincial Science and Technology Commission. Accreditation Committee of experts, agreed that: "In China’s gear processing industry from soft to hard tooth surface transition process, the results create a tooth that suits our national conditions
