摘要
MG400/900-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。根据采煤机现在的发展动态通过分析与比较，确定了采煤机的牵引方式，并且对牵引部的基本参数进行了详细的计算，介绍了行走部传动系统的拟定；传动装置的运动及动力参数的计算；各个齿轮的几何尺寸的确定；以及轴、行星齿轮和花键的设计计算和校核。
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。
MG400/900-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。

Abstract
The MG300/900-WD coal mining machine is more than one kind of motor-driven, crosswise arrangement alternating current hauling coal mining machine. TAccording to the coal mining machine now development through analysis and comparison, determine the shearer traction, and the traction of the basic parameters are calculated in detail, introduces thewalking part of the transmission system of the protocol; transmission device of kinematic and dynamic parameters calculation; each gear to determine the geometric size, and shaft; planetary reduction gear and spline design calculation and checking.
he pulling motor outputs torque decelerates after the third-level cylindrical gears and the second-level planet gear reduction gear, by the planet carrier outputs,withwalks lining on the feet and palms of buddha meshing through the driving gear, bywalks again round and onworking surface scraper conveyer's rack rail meshing causes the coal mining machine back and forth towalk, simultaneously the brake spindle output shaft is connected through the key and the brake, realizes the electricity hauling department brake.
The MG400/900-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 effectiveworking surface the need.
