MG300/700采煤机牵引部设计 摘要 本文是新型采煤机部整体设计的说明书。通过参考大量和，分析以往典型采煤机在中、厚煤层开采中的，利用多种改进，权衡许多重要参数最终定为，性能十分。 本文主要是关于的整体设计，主要阐述各的选型及选型和改进措施，其中以为主。还有关于的总体传动系统传动比的计算。最后，为的生产和使用要求和建议，帮助用户能更好的。设计说明书中还配有图纸关键：采煤机；； 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牵引电动机的选择 3.3传动比确定及分配 3.4各级传动转速、功率、转矩的计算 第四章 齿轮、轴、轴承、键的选用与校核 4.1 齿轮传动设计 4.2花键轴的设计计算 4.3轴承的选型及寿命的计算.......................................................
