摘    要

      给煤设备是煤矿生产系统的主要设备之一,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Ｋ型往复给煤机生产能力小,不能满足大型矿井的要求，因此,改进和扩大现有Ｋ型往复给煤机是完全必要的。本设计的往复式给煤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：往复式给煤机的发展历史，用途，组成及工作原理；往复式给煤机的特点；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。在本次往复式给煤机的设计过程中，着重对减速器、传动平台、曲柄连杆机构、托辊进行了分析和设计。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。

ABSTRACT

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, installation and dismantling inconvenient, and the disadvantages of implants uniform. 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 describes : Reciprocating to the coal history of the development, use, composition and physics; Reciprocating to the characteristics of coal; Design of the general steps; the use of the existing problems and improvement measures; installation and maintenance and so forth. Reciprocating in this coal to the design process, focusing on reducer, transmission platform, crank linkage, Idler for the analysis and design. Important components of the stress analysis, strength check, in accordance with its common failure mode, Factors and basic design requirements, is an important component of the stress analysis, strength and stiffness of the design method.
Keywords : Reciprocating to the coal;  Reducer; Crank linkage;  Analysis;  Strength Check
