摘    要

      給煤設備是煤礦生產系統的主要設備之一,給煤設備的可靠性,特別是關鍵咽喉部位給煤設備的可靠性,直接影響整個生產系統的正常運行。生產實踐證明,現有的往復式給料機的生產能力小、安裝和拆卸不方便、受力不均勻等缺點。，隨著煤炭工業的發展,煤礦井型不斷地擴大,現有Ｋ型往復給煤機生產能力小,不能滿足大型礦井的要求，因此,改進和擴大現有Ｋ型往復給煤機是完全必要的。本設計的往復式給煤機是在原有的基礎上作了一些改進，具有結構簡單、維修量小、性能穩定、噪音低、安裝方便等優點。
本文主要介紹了：往復式給煤機的發展歷史，用途，組成及工作原理；往復式給煤機的特點；設計的一般步驟；使用中存在的問題及改進措施；安裝和維護等內容。在本次往復式給煤機的設計過程中，著重對減速器、傳動平臺、曲柄連桿機構、托輥進行了分析和設計。對重要的部件進行了受力分析、強度的校核，根據其常見失效形式、影響因素及基本設計要求，給出了重要部件的受力分析、強度和剛度的設計方法。
關鍵詞：往復式給煤機； 減速器； 曲柄連桿機構； 受力分析； 強度校核

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
