目前我国电气化铁路多在坡道较大、弯道较多的山区,机车轮对的工作条件十分恶劣。如何减少轮缘磨耗是电力机务系统的一个重要课题。减少轮缘磨耗,不仅可以减少机车检修工作量,提高机车运用率,而且会带来十分显著的经济效益。一、我段机车轮缘的磨耗情况我段地处鄂西山区,担负着襄渝线东段的运输任务,该区段全长364km,共有277处弯道,占该区段全长的35％。于1980年8月通车,采用SS1型电力机车,在头两年内,机车轮缘磨耗十分严重。对于旋削后的标准轮对,多数机车只运行一个定修公里(2.3～3.5×10~4km)就磨耗到限,需要旋轮,少数机车连一个定修公里也走不到就要临修旋轮。部分机车自1980年8月至12月的轮缘磨
At present, China's electrified railways are mostly in mountainous areas with large ramps and more corners, and working conditions of wheelsets are very poor. How to reduce the wheel flange wear is an important issue of the electrical machinery system. Reduce wheel wear, not only can reduce the workload of locomotive maintenance, improve locomotive utilization, and will bring very significant economic benefits. First, the wear of the locomotive rim I section is located in the western Hubei mountains, carrying the eastern part of the Xiang-Yu line transport mission, the section length of 364km, a total of 277 corners, accounting for the length of the section 35 %. Opened in August 1980, using SS1 electric locomotive, locomotive rim wear is very serious in the first two years. For the standard rotation after cutting, most locomotives only run a fixed kilometers (2.3 ~ 3.5 × 10 ~ 4km) to wear to the limit, the need for rotary, a few locomotives even a fixed repair kilometers also will not be able to go Pro repair wheel. Part of the locomotive since August 1980 to December rim mill
