摘 要MG400/900-WD 型采煤机是一种多电机驱动的交流电牵引采煤机。这种采煤机运用的电牵引技术，拥有很强大的功能。这是我国技术突出的表现。我对这次采煤机的设计研究进行了详尽的剖析，对每一个参数进行了详尽的计算，分析了电牵引采煤机的各个重要组成部分，然后确定了行走部的各个零部件，最后完成了选型。选型确定的同时，开始着手查看齿轮的研究，详细的分析之后，确定齿轮的选材和整体的传动方案，然后对传动的各个部分进行详细的设计和校核，轴的设计和选材是最后完成的，也同样进行了校核。本文在末尾还介绍了采煤机日常的保养和维护，这也是详尽分析后的结果。总之，本文的设计是为了采煤机能更加的完整，能适应恶劣的地底环境，创造出可以让企业进步的利益。还有是为了能够更安全的进行地下的工作。关键词：电牵引采煤机；行走部；齿轮；减速机构 AbstractMG400 / 900-WD shearer is a multi-motor driven AC traction shearer. The electric traction technology used by this type of shearer has powerful functions. This is an outstanding performance of China's technology. I carried out a detailed analysis of the design and research of this shearer, carried out a detailed calculation of each parameter, analyzed each important component of the electric traction shearer, and then determined each part of the walking part, and finally Completed the selection.At the same time when the type selection is determined, the research of the gear is started. After detailed analysis, the material selection of the gear and the overall transmission scheme are determined, and then each part of the transmission is designed and checked in detail. The shaft design and material selection are finally completed Yes, it was also checked.This article also introduces the daily maintenance and maintenance of the shearer at the end, which is also the result of detailed analysis.In short, the design of this article is to make the coal mining machine more complete, adapt to the ...
