内容简介：

摘 要G400/900-WD 型采煤机是一种多电机驱动，横向布置的交流电牵引采煤机。该机功率大，多电机横向布置，整机结构紧凑，采用交流变频调速系统，变频调速采用机载式。截割电机、牵引电机等主要元部件均可从采空区抽出，容易更换，方便维修。牵引电机输出的转矩经三级圆柱齿轮和二级行星齿轮减速器减速后，由行星架输出，通过驱动轮与行走轮相啮合，再由行走轮与工作面刮板输送机上的齿轨啮合使采煤机来回行走，同时制动轴输出轴通过键与制动器相连，实现电牵引部的制动。左右牵引部，中间电控箱的联结螺柱，定位销，摇臂与左右电牵引部铰接销轴四组，这些装置将采煤机各大部件联接成一个整体，起到紧固及连接的作用。牵引部与行走部做成一体，使机身整体尺寸紧凑，缩小了机身宽度。G400/900-WD 型采煤机，操作方便，可靠性高，事故率低，开机效率高，可满足高产高效工作面的需要。关键词关键词：采煤机；牵引部；行走部；行星齿轮ABSTRACTThe G400/900-WD coal mining machine is more than one kind of motor-driven, crosswise arrangement alternating current hauling coal mining machine. This machine power is big, the multi-electrical machinery crosswise arrangement, the complete machine structure is compact, uses the exchange frequency conversion velocity modulation system, the frequency conversion velocity modulation uses aircraft-borne -like. Cuts the electrical machinery, the pulling motor and so on main part to be possible to extract from the worked-out section, easy to replace, facilitates the service.The pulling motor outputs torque decelerates after the third-level cylindrical gears and the second-level planet gear reduction gear, by the planet carrier outputs, with walks lining on the feet and palms of buddha meshing through the driving gear, by walks again round and on working surface scraper conveyers rack rail meshing causes the coal mining machine back and forth to walk, simultaneously the brake spindle output shaft is connected through the key and the brake, realizes the electricity hauling department brake.About the hauling department, the middle electrically controlled boxs joint stud, the positioning pin, the rocking shaft sells the axis four groups with about electricity hauling department hinge, these installments join coal mining machine various major assemblies a whole, plays the fastening and the connection role. The hauling department with walks to make a body, caused the fuselage overall size to be compact, reduced the fuselage width.The G400/900-WD coal mining machine, the ease of operation, the reliability is high, the accident rate is low, the starting efficiency is high, may satisfy the high production highly effective working surface the need.Key word: The coal mining machine； the hauling department； walks；Planet gear目目 录录1 1 概述概述 .11.1 采煤机的发展概况.11.2 国际上电牵引采煤机的技术发展状况.11.3 国内电牵引采煤机的发展状况.31.3.1. 20 世纪 70 年代是我国综合机械化采煤起步阶段.31.3.2 .20 世纪 80 年代是我国采煤机发展的兴旺时期.41.3.3 .20 世纪 90 年代至今是我国电牵引采煤机发展的时代.51.4 采煤机的发展趋势.71.5 采煤机类型.71.6 采煤机的组成.101.7 电牵引采煤机的优点.122 2 牵引部的设计牵引部的设计 .142.1 牵引机构传动系统.142.1.1 主要技术参数.142.1.2 电动机的选择.142.1.3 传动比的分配.152.2 牵引部传动计算.172.2.1 各级传动转速、功率、转矩.172.3 牵引部齿轮设计计算.182.3.1 齿轮 1 和惰轮 2 的设计及强度效核.182.3.2 齿轮 3 和惰轮 4 的设计及强度效核.242.3.3 齿轮 5 和惰轮 6 的设计及强度效核.302.4 牵引部行星机构的设计计算.352.4.1 行星齿轮的计算.372.4.2 行星轮啮合要素验算.493 3 轴的设计及校核轴的设计及校核 .533.1 确定轴的最小直径.533.2 轴的校核.563.3 花键的强度校核.633.4 轴承的
