【正文】 河南理工大學(xué)本科畢業(yè)設(shè)計(jì)（論文） I 摘 要 機(jī)械系統(tǒng)是機(jī)械零、部件同作用的整體，是零、部件服務(wù)的目標(biāo)。本次設(shè)計(jì)從分析 采煤機(jī) 設(shè)計(jì)的任務(wù)和目標(biāo)開始，介紹機(jī)械系統(tǒng)的組成，各組成部分之間的配置，選擇和結(jié)構(gòu)匹配性設(shè)計(jì)，以及進(jìn)行 采煤機(jī) 整體設(shè)計(jì)時(shí)應(yīng)該考慮哪些問(wèn)題，目的是培養(yǎng)學(xué)生多樣性設(shè)計(jì)，結(jié)構(gòu)設(shè)計(jì)創(chuàng)新和整體設(shè)計(jì)的能力。 本次設(shè)計(jì)主要是液壓牽引采煤機(jī)的總體設(shè)計(jì)，其主要包括總體結(jié)構(gòu)、 機(jī)身聯(lián)接 和主要附屬裝置設(shè)計(jì)。在論文中首先對(duì)采煤技術(shù)做了簡(jiǎn)單介紹，然后對(duì)采煤機(jī)的原理做了簡(jiǎn)單介紹，接著對(duì)采煤機(jī)的部件組成進(jìn)行了尺寸計(jì)算和校核。該設(shè)計(jì)代表了采煤機(jī)設(shè)計(jì)的一般過(guò)程。 關(guān)鍵詞： 液壓 采煤機(jī)、總體設(shè)計(jì)、機(jī)身聯(lián)接、附屬裝置 河南理工大學(xué)本科畢業(yè)設(shè)計(jì)（論文） II Abstract A mechanical system is a synergistic collection of machine elements, and designing a mechanical system is the final goal in studying machine design. This paper starts with the analyses of tasks and objectives in designing a shearer, followed by its position,selection and patibility of mechanical units and the main considerations in designing a shearer. The purpose of this paper is to help the undergraduates learn skills of diversified design, creative design and systematic design . This design mainly introduces the general design of a hydraulic tow shearer, including its general structure、 fuselage connection and main accessory devices of the design. In the first paper introduces mining technology and the principle of the shearer, then calculation and check for main ponents and the design dimension. The design represents the general design process of a shearer.
