MG300/700采煤机牵引部设计 摘 要 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一些要求和建议，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。 关键词：采煤机；牵引部；行走箱；牵引机构；The Design of Shearer Traction Department 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.. Key words: Shearer; traction Department; walking mechnism; traction 目录 摘 要 Abstract 第一章 绪 论 1.1引言 1.2 采煤机械的技术现状与发展趋势 1.3中国煤炭开采的重要性 1.4 小结 1.5设计意义及需解决的问题 第二章 牵引部的整体方案 2.1牵引形式的选择 2.2牵引机构的选择 2.3牵引部的组成及特点 2.4牵引机构结构和动力设计方案的确定 2.5此种设计对牵引部的要求 2.6牵引阻力的确定 2.7减速机构的选用 2.8润滑方式及齿轮油的确定 2.9密封形式的确定 第三章 牵引部的主要技术参数及传动比的设定 3.1机械传动系统 3.2牵引电动机
