轮对的常见故障分析及预防措施 电气化铁道技术专业毕业论文.pdf

起着非常重要的作用。铁道车辆是路运输中直接运载旅客和货物的工具，是铁路 运输中的一个重要环节。 近年来，随着我国经济、科技、贸易的振兴，文化和人员交流的增多，旅游 事业的发展，促进了国列车速度提升的研制及实施。 轮对是转向架的主要部件之一，它的功能是承受车辆的自重和载重，并通过 轮对在钢轨上滚动完成车辆运行，他的运用条件十分恶劣，经常檫伤、剥离、掉 块、热烈和疲劳损坏等情况。其性能的好坏，对行车安全具有身份重大的影响。 Railway is the artery of national economy. Railway transport for the national most tasks, plays a very important role in national economy. Railway vehicle is carrying passengers and cargo in direct road transportation tools, is an important part of railway transportation. In recent years, with the revitalization of Chinas economy, science and technology, trade, cultural and personnel exchanges on the rise, the development of tourism, promote the development and implementation of the speed of the train. Wheel is one of the main components of the bogie, its function is to bear the weight and load of vehicle, and through the round of complete vehicle running on rolling on the rail, the use of his condition is very bad, often grazed and, stripping, impellers, hot and fatigue damage, and so on and so forth. The stand or fall of its performance, identity does not have significant influence on the traffic safety. 目录 第一章 绪论8 1.1 铁道车辆的叙述8 1.2 货车轮对的简介8 1.3 轮对的要求……9 1.4 货车轮对的发展趋势…10 第二章 车轴 12 2.1 车轴的简介 12 2. 1.1 车轴各部分的名称及作用 12 2. 1.2 车轴的尺寸及材质要求………………………………………………..13 2.2 车轴故障 15 2.2.1 产生原因………………………………………………………………16 2.2.2 车轴常见故障及预防措施…………………………………………… 18 第三章 车轮………………………………………………………………………..19 3.1 车轮的简介 19 3.1.1 车轮各部分名称及作用………………………………………………..20 3.1.2 车轮的种类及材质要求……………………………………………….21 3.2 车轮的故障… ……………………………………………….…………….22 3.2.1 车轮的常见故障………………………………………………………22 3.2.2 产生原因………………………………………………………………25 3.2.3 车轮的检修……………………………………………………………26 第四章 轮对的探伤检查……………………………………………………………29 4.1 分类及作用……………………………………………………………….29 4.2 电磁探伤………………………………………………………………….29 4.3 超声波探伤……
