JB179—81《渐开线圆柱齿轮精度制》已经批准发布。并于83年元月1日实施。新标准的贯彻过渡工作,涉及面广,技术问题复杂,因此要先行试点,摸清现有齿轮生产的水平,通过采取必要的技术和管理措施,提高齿轮制造质量,以达到标准的精度要求,为全面贯彻齿轮新标准摸索和积累经验。一机部科技司经与上海市机电一局及有关单位商议,决定在上海汽车齿轮厂、上海机床
JB179-81 “involute cylindrical gear precision system” has been approved for release. And in January 83, January 1 implementation. The implementation of the new standards in the transitional work involves a wide range of technical issues are complex. Therefore, we must first pilot to find out the level of the existing gear production, by taking the necessary technical and management measures to improve the quality of gear manufacturing to meet the standard accuracy requirements, To fully implement the new gear standards to explore and gain experience. A machine department of Science and Technology Division and the Shanghai Municipal Bureau of Electrical and a discussion of the relevant units, decided to Shanghai Automotive Gear Factory, Shanghai Machine Tool
