摘要 本毕业设计的课题主要任务是本文在详述国内外研究现状的基础上，对的进行了设计，对一些关键部分进行了设计计算。重点是的、的设计及校核。 本文设计的 关键词：Abstract The graduation design topic is given to the coal is Chinas main energy, improve coal output is beneficial to the economic development of our country. The roadheader is mainly composed of cutting, walking, shipment, loading four mechanism and hydraulic, water, electric three generation system. The roadheader is divided into two kinds, they are horizontal and vertical . The main task of this design is to study the influence of the horizontal roadheader cutting to coal yield. This paper details the heading machine on the basis of the studies at home and abroad. In this paper , I design the horizontal roadheader cutting mechanism, and calculate some key parts of the design. The focus of design is the analysis of horizontal roadheader cutting head on motion and force,。Another focus of design is the analysis of cutting tooth on the motion and force . .Besides, the design and check of rotary mechanism is also very important In this paper ,the design of roadheader is horizontal, the work is mainly on the design of cutting head, cutting, rotary table and so on. The cutting part is used to install a speed reducer; the cutting part for installing reducer motor; rotary table is used to control the cutting head to sway and rotary . Keywords: roadheader ；horizontal；cutting head；rotary table 目 录 I Abstract II 1. 绪 论 1 1.1本课题的研究目的及意义 1 1.2国内外掘进机的发展趋势 2 1.3横轴式掘进机截割机构的设计现状 5 1.4本章小结 7 2. 横轴式掘进机截割机构的总体方案设计 1 2.1横轴式掘进机的设计要求 1 2.2横轴式掘进机的方案设计 1 2.3设计参数的确定 3 2.4截齿设计 8 2.5截割结构及二维装配图 13 2.6本章小结 18 3. 掘进机的三维建模与运动学仿真 19 3.1截割头三维建模 19 3.2其他重要零件的三维建模 24 3.3齿轮轴的运动学仿真 27 3.4本章小结 30 4. 端盖数控加工 31 4.1数控加工的概述 31 4.2端盖铣削加工 32 4.3本章小结 41 5. 齿轮轴ANSYS分析 42 5.1齿轮轴ANSYS分析过程 42 5.2本章小结 46 参考文献 47 致谢 48 附录一 49 附录二 74 1. 绪 论 1.1本课题的研究目的及意义1.1.1本课题的研究1.1.2本课题的研究意义 本次毕业设计是对横轴式掘进机进行设计和研究，并在此基础上对横轴式掘进机的截割部进行改进。然而，由于横轴式掘进机的运动比较复杂, 截割过程载荷多变 , 致使机器工作振动比较大, 而实际计算其动态过程又非常的困难。所以, 从理论上研究掘进机的性能, 以及在此基础上探讨改进其动态特性方面的进展十分缓慢。通过横
