随着铁路牵引动力内燃化的发展,精密齿轮制造量日益增多。为适应批量生产内燃机车的需要,铁道部向国外引进了一批配有精密分齿板的磨齿机,但每台仅带3～4块精密分齿权,迫使机床不能发挥作用。若继续进口精密分齿板,外国资本家要价很高,以此卡我们。此外,已使用的磨齿机,分齿板长期使用,精度日趋下降,急需更换。遵照伟大领袖毛主席独立自主,自力更生的教导,在部局领导支持、厂所领导重视下,厂所结合,接受了研制精密分齿板的任务。三结合研制小组先后设计研制了精密光栅分度头,φ300毫米精密分齿板,差动双触头电感式
With the development of railway traction power internal combustion, the production of precision gears is increasing. In order to meet the needs of mass production of diesel locomotives, the Ministry of Railways introduced a number of gear grinding machines equipped with precision splitter plates to foreign countries, but each with only 3 to 4 precision gear points forced the machine tool to fail to work. If you continue to import precision points tooth plate, foreign capitalists asking price is very high, in order to card us. In addition, the use of gear grinding machine, sub-tooth plate long-term use, accuracy declining, urgent need to be replaced. Following the guidance of Chairman Mao’s independence and self-reliance by the great leader, under the leadership of the ministry and the leadership of the factory, the factory has been combined and accepted the task of developing a precision splitter. Three combination of research and development team has designed a precision grating indexing head, φ300 mm precision points tooth plate, differential double contact inductive
