山西农业大学工程技术学院毕业论文毕业设计说明书中文摘要往复式煤炭输送机设计摘要：煤炭是我国能源安全的基石。煤炭工业是我国重要的基础产业，我国的煤炭产量已是世界第一位，是煤炭生产大国，现在我国煤炭工业已具备了设计、施工、装备及管理千万吨露天煤矿和大中型矿井的能力。但是，我国煤炭开采技术装备总体水平低，煤炭生产技术装备是机械化、部分机械化和手工作业并存的多层次结构。技术和装备水平低，严重影响煤炭的生产效率。保障煤炭供应是国家加强煤炭工业宏观调控的重点之一，煤炭深加工更是国家重工业发展的重中之重，输送机设备作为煤矿生产系统的基础设备,给煤设备的可靠性,特别是关键咽喉部位给煤设备的可靠性,直接影响整个生产系统的正常运行。生产实践证明,现有的往复式给料机的生产能力小、安装和拆卸不方便、受力不均匀等缺点。，随着煤炭工业的发展,煤矿井型不断地扩大,现有型往复煤炭输送机生产能力小,不能满足大型矿井的要求，因此,改进和扩大现有型往复煤炭输送机是完全必要的。本设计的往复式煤炭输送机是在原有的基础上作了一些改进，具有结构简单、维修量小、性能稳定、噪音低、安装方便等优点。本文主要介绍了：往复式煤炭输送机的发展历史，用途，组成及工作原理；往复式煤炭输送机的特点；设计的一般步骤；使用中存在的问题及改进措施；安装和维护等内容。在本次往复式煤炭输送机的设计过程中，着重对减速器、传动平台进行了分析和设计。对重要的部件进行了受力分析、强度的校核，根据其常见失效形式、影响因素及基本设计要求，给出了重要部件的受力分析、强度和刚度的设计方法。关键词：往复式煤炭输送机 减速器 受力分析 强度校核 毕业设计说明书外文摘要Reciprocating coal conveyorABSTRACTCoal is the cornerstone of Chinas energy security. The coal industry is an important basic industries，Chinas coal production is the first in the world, coal producing countries，however, coal mining technology and equipment of our overall low level of，coal production is mechanized equipment, part of both mechanized and manual operation of the multi-level structure. Low level of technology and equipment, seriously affect the efficiency of coal production.To protect the supply of coal is the coal industry to strengthen macro-control of one of the key points，deep processing of coal is the most important national industrial development,coal mine production equipment is the one of the main equipment for coal equipment reliability, Special location is the key to the throat of coal equipment reliability, a direct impact on the entire production system to normal operation. Practice has proved that the existing reciprocating Feeder small production, With the development of coal industry and coal-wells continues to expand, the existing K-type reciprocating coal production capacity of the small plane, unable to meet the requirements of large-scale mine, therefore, improve and expand existing K-type reciprocating to the coal machine is totally necessary. The design of the reciprocating to the coal on the basis of the original made some improvements, it has a simple structure and a small amount of maintenance, stable performance, low noise, the installation is easy.This paper introduced：Reciprocating coal conveyor history of the development, use, composition and physics; Reciprocating to the characteristics of coal; focusing on reducer, transmission platform, crank linkage, strength check, in accordance with its common failure mode, Factors and basic design requirements, is an important component of th
