从六十年代到七十年代随着国外铁路高速行车的发展,作为电力机车和电传动内燃机车重要部件的牵引齿轮,其传动技术也有了很大发展。目前,我国电力机车和电传动内燃机车牵引齿轮的寿命都很低。故障率和破损率较高,提高国产牵引齿轮的质量,发展我国牵引齿轮传动的技术水平,在铁路运输调整时期,对提高电力机车和电传动内燃机车利用率有很大的意义。现将国外牵引齿轮传动技术的某些发展情况作一简述,以作借鉴和参考。
From the 1960s to the 1970s, with the rapid development of foreign high-speed railways, the transmission technology of traction gears as an important component of electric locomotives and electric transmission diesel locomotives has also been greatly developed. At present, China’s electric locomotive and electric drive diesel locomotive traction gear life are very low. High failure rate and breakage rate. It is of great significance to improve the quality of domestic traction gears and develop the technical level of traction gears in our country. It is of great significance to improve the utilization ratio of electric locomotives and electric transmission diesel locomotives in the period of railway transportation adjustment. Now some of the overseas traction gear transmission technology to make a brief description of the situation for reference and reference.
