可靠性问题,是一个涉及面较广的综合性技术问题。它要求设计、制造和运用各部门共同努力,从而使产品耐久而无故障地工作。在我国铁路运输中为提高电力、内燃机车牵引电机的可靠性,各有关单位正在努力做好这一工作。据统计,广州、济南、北京、丰台及石家庄等五个机务段使用的东风4型内燃机车410牵引电动机的故障率:77年为42%,78年为27.3%,79年为24.2%,80年为22.9%。可见牵引电动机故障占机车故障的比例很大,因而提高牵引电动机的可靠性,降低其故
Reliability issues, is a comprehensive technical issues involving a wide range. It requires the design, manufacture and use of various departments to work together, so that the product Durable and trouble-free work. In order to improve the reliability of traction motors for electric power and diesel locomotives in China’s railway transportation, all relevant units are making great efforts to do this work. According to statistics, the failure rates of traction motor of Dongfeng 4 diesel locomotive 410 used in five depots in Guangzhou, Jinan, Beijing, Fengtai and Shijiazhuang are 42% in 1977, 27.3% in 1978, 24.2% in 1979 and 80% in 1979 Year is 22.9%. Visible traction motor fault accounting for a large proportion of locomotive failure, thereby improving the reliability of the traction motor to reduce its
