MG300-700采煤机牵引部总体设计本文是新型采煤机牵引部整体设计的说明书。设计通过参考大量产品资料和指导老师的指导，分析以往典型采煤机在中、厚煤层开采中的液压部分存在的问题，利用多种方法改进，权衡许多重要参数最终将牵引部定为由液压装置提供动力，齿轮在轨道上行走的基本形式，将采煤机的直线行走运动性能十分稳定。
本文主要是关于牵引部的整体设计以及行走箱的设计，主要阐述行走箱各轴、齿轮以及轴承等的选型及选型和改进措施，其中以动力传动与行走机构的确定为主。还有关于牵引部的总体传动系统的传动比的计算。最后，为牵引部的生产和使用中遇到的实际问题以及问题的解决提了-些要求和建议，帮助用户能更好的使用机器。设计说明书中不易表达出来的地方还配有图纸来说明。

Abstract
Shearer traction in this paper is the new Department of the overall design of brochures. Design of a large number of products through reference information and guidance to the guidance of teachers， analysis of typical Shearer in the past， thick seam mining in the hydraulic part of the existing problems， and use various methods to improve balance many important parameters of the traction will eventually be ground Hydraulic devices powered gear running on the track in the basic form， Shearer will walk a straight line movement of very stable.
This article is about the overall design of the Department of traction， as well as the design of walking box， walking on the main shaft， gears and bearings， such as the selection and selection and improvement measures， Power Traction and walking mechanism is mainly confirmed. Traction is also available on the Department of the overall transmission ratio of the transmission system of calculation. Finally， the Department of traction for the production and use of the practical problems encountered in the settlement of the issue and mentioned a number of requests and suggestions to help users better use of machinery. Design Manual difficult to express in the local also has drawings to illustrate..
