采煤机牵引部的运动仿真

摘要

MG300/720-AWD型采煤机是一种多电驱动，横向布置的交流电牵引采煤机。该机功率大，多电横向布置，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连接成一个整体，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。

MG300/720-AWD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 MG300/720-AWD 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 surf ace scraper conveyer’s 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 d epartment, the middle electrically controlled box’s 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 MG300/720-AWD 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 words: The coal mining machine; The hauling department; Planet gear.
