- -Ⅰ- 地铁鼓形齿联轴器的研究开发 摘要 本文对地铁鼓形齿联轴器国内外的现状作了充分、翔实的调研 后，发现在铁路运输方面，国内有关鼓形齿联轴器的研究甚少。目前， 国内在城市轻轨、地铁动车、快速列车用鼓形齿联轴器方面的研究几 乎是空白，没有成熟的理论指导，没有成功运营的实践。在我国运行 的地铁列车用联轴器大都为进口产品。针对这种现状，本文对地铁列 车用鼓形齿联轴器作了深入的研究，提出设计方案，试制出鼓形齿联 轴器，并在试验台上进行了空载、仿真加载的试验，试验的结果表明 所设计的鼓形齿联轴器达到设计要求。本文的主要研究内容如下： （1）通过资料的查阅，对应用在地铁列车上的各种动力传递用联 轴器的国内外现状进行了详细的的分析、研究，比较各自的优缺点， 得出目前发展鼓形齿联轴器的合理性、可行性，并提出鼓形齿联轴器 设计上的关键问题，给出设计方案； （2）从选材开始，通过材料工艺试验以及材料的性能试验，筛选 出满足性能要求、工艺性好而且经济的材料。利用成熟的齿轮理论知 识对地铁鼓形齿联轴器进行了全面的设计、计算；利用自编软件及成 熟的设计软件 IDEAS 对设计的鼓形齿联轴器进行了详细的有限元分 析，试制出鼓形齿联轴器； （3）在牵引齿轮综合试验台上进行了空载、仿真加载试验。进行 的空载位移补偿量的验证结果表明满足设计要求；进行的全载荷位移 补偿量的试验及承载能力的仿真试验的结果同样也满足设计要求。 关键词: 鼓形齿 联轴器 有限元 强度分析 试验 - -Ⅱ- Researches on Crown Gear Coupling for Metro ABSTRACT This dissertation makes a thorough investigation on the current situation of crown gear coupling for subway. After investigation, it was found out that the studies on crown gear coupling are few in commercial railway in China. Now most of couplings in subway are imports. Because of this situation, this paper carries through a series of researching work and brings through the project of crown gear coupling design. A crown gear coupling was manufactured, and then some experiments about crown gear coupling was done on test-bed. The test result showed out that the designed crown gear coupling is met to the buyer’s requirement. The main jobs of this paper are shown as follows: Given a thorough investigation on the current situation of crown gear couplings by using preterit data, and which is good or bad is found out. The key point of crown gear coupling is given. The project of crown gear coupling is indicated. Some experiments about material of crown gear coupling were done. Through the experiments, the good technics material is found. Calculated and analyzed the intensity of crown gear coupling by using the compiled software and the Software I-DEAS. To verify the rationality, a crown gear coupling was manufactured. Idle load test and simulate load test are done on the test-bed of traction ge
