1、双滚筒采煤机牵引部设计摘要全套图纸，加153893706MG300/690-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二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轮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

2、的联结螺栓，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。牵引箱与行走部独立箱体设计，配套适应性强。MG300/690-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：采煤机；牵引部；行走部；行星齿轮72DoubledrumshearerhaulageunitdesignABSTRACTTheMG300/900-WDcoalminingmachineismorethanonekindofmotor-driven,cro
