1、 摘摘 要要 对中厚煤层的开采在煤矿生产中有重大的经济利益，而采煤机的滚筒 在开采过程中有相当重要的作用， 其好坏直接影响到采煤的效率， 基于此， 本文对MG160/390WD电牵引采煤机的滚筒进行了分析与设计。本文通过查 阅文献、 寻求指导老师帮助以及与同学合作的方式， 对采煤机的工作原理、 截割机构的传动和结构设计进行了阐述；对截割部中的各个轴的传动功率 和转速进行了计算，并重点对减速箱的一、二级行星减速器中的各个齿轮 进行了计算分析；对截齿的材料以及截齿的配置和固定、截割部减速器的 润滑情况进行了文献查阅。通过以上工作的整合，得出滚筒中各主要零部 件的尺寸和大体形状，并在autocad画

2、图软件中体现出来。从而基本完成了 毕业设计论文的要求，较为圆满的完成了任务。本论文通过图文并茂的形 式更为直观的展现了设计思路和设计内容及成果，有较好的效果。 关键词：滚筒；截齿；行星轮减速器 Abstract In the mining of thick coal seam in coal mine production is a major economic benefit, while the roller in the mining of coal mining machinery in the process to have very important function, its

3、direct influence on the efficiency of coal mining, and based on this, the paper to MG160/390-4 WD electric traction shearer drum of the analysis and design. This article through the literature for guidance, the teachers help with classmates and cooperation way of coal winning machine, the working pr

4、inciple, cut cut the transmission and structure institutions design is discussed in this paper; For cutting part of each shaft power transmission and speed are calculated, and focus on the gear box, level 2 of each planet reducer gear is calculated and analyzed; To cut tooth material and cut teeth configuration and fixed, cutting part of the gear lubrication literature inspection. Through the integration of the above work, it is concluded that the main parts in the drum of the size and over
