一机部机械研究院郑州机械研究所根据国家标准总局的标准化工作计划,负责组成工作组,起草了JB179-81《渐开线圆柱齿轮精度制》标准,代替JB179-60《圆柱齿轮传动-公差》。一机部机床行业在座谈讨论新标准的贯彻工作时,根据部科技工作会议积极采用国际标准的精神,提出了齿形公差直接采用ISO标准的建议。部研究后,同意这个建议,并于1981年10月4日通知起草单位对JB179-81进行修改。这一修改工作已于11月结束,修改后的JB179-81部标准,明确采用ISO1328-75《平行轴渐开线齿轮ISO精度制》国际标
According to the standardization work plan of the State Administration of Standards, Zhengzhou Machinery Research Institute under the Ministry of Machine Building is responsible for forming a working group and drafting the JB179-81 “Involute Cylindrical Gear Accuracy” standard instead of JB179-60 “Spur Gears - Tolerance ”. When discussing the implementation of the new standard in the workshop of a machine tool industry, according to the spirit of actively adopting the international standard by the Ministry of Science and Technology Work Conference, the proposal of directly adopting the ISO standard for the tooth profile tolerance was put forward. After the ministry’s study, it agreed with this suggestion and notified the drafting unit on October 4, 1981 to amend JB179-81. This revision has been completed in November, the revised JB179-81 standards, the explicit use of ISO1328-75 “parallel axis involute gear ISO precision” international standard
