【正文】 本科畢業(yè)設(shè)計（論文）通過答辯摘 要隨著我國經(jīng)濟(jì)的迅速發(fā)展，對能源的需求量將日益增加。而作為我國傳統(tǒng)的煤炭是推動我國經(jīng)濟(jì)持續(xù)健康發(fā)展的重要能源保障。煤炭在世界范圍內(nèi)的使用僅次于石油，屬于世界第二大使用能源。是我國的主要能源，在一次能源生產(chǎn)和消費(fèi)中占主導(dǎo)地位。我國正處在全面建設(shè)小康社會的現(xiàn)代化進(jìn)程中，經(jīng)濟(jì)的發(fā)展對煤炭的需求快速增長。進(jìn)入21世紀(jì)，科學(xué)技術(shù)有著飛速的發(fā)展，伴隨著科學(xué)技術(shù)的發(fā)展機(jī)械制造技術(shù)也有了較大的發(fā)展。刮板運(yùn)輸機(jī)作為采煤工作面和采區(qū)巷道的運(yùn)煤機(jī)械是煤礦使用量最大、消耗量最多的重要設(shè)備，是煤炭裝運(yùn)的第一個環(huán)節(jié)，很大程度上決定了采煤工作面的生產(chǎn)能力和效率。在工程中得到了廣泛的應(yīng)用。它由它由機(jī)頭、中間部和機(jī)尾部等三個部分組成。刮板輸送機(jī)的工作原理是，將敞開的溜槽，作為煤炭、矸石或物料等的承受件，將刮板固定在鏈條上（組成刮板鏈），作為牽引構(gòu)件。當(dāng)機(jī)頭傳動部啟動后，帶動機(jī)頭軸上的鏈輪旋轉(zhuǎn)，使刮板鏈循環(huán)運(yùn)行帶動物料沿著溜槽移動，直至到機(jī)頭部卸載。刮板鏈繞過鏈輪作無級閉合循環(huán)運(yùn)行，完成物料的輸送。但由于SGW250型刮板輸送機(jī)還存在著許多缺點(diǎn)，需要進(jìn)一步的改進(jìn)，來進(jìn)一步提高采煤的效率。它的設(shè)計制造涵蓋了運(yùn)動轉(zhuǎn)換，動力傳輸，變速機(jī)構(gòu)，鑄鍛件的設(shè)計的機(jī)械設(shè)計及工藝內(nèi)容。我設(shè)計了邊雙鏈型刮板輸送機(jī)，本文首先綜合比較了各種類型輸送機(jī)的特點(diǎn)，根據(jù)實(shí)際情況選用了邊雙鏈型刮板輸送機(jī)。而后，經(jīng)過半年的思考鉆研對邊雙鏈型刮板輸送機(jī)進(jìn)行了總體結(jié)構(gòu)設(shè)計。對機(jī)頭傳動裝置、過渡槽、中部槽、刮板鏈、刮板、鏈輪、機(jī)尾等主要部件進(jìn)行了技術(shù)分析和結(jié)構(gòu)設(shè)計，完成了刮板輸送機(jī)的整體設(shè)計。此次設(shè)計的刮板輸送機(jī)的特點(diǎn)是過煤空間大，消耗能量小，具有很強(qiáng)的適應(yīng)性。 ABSTRACT With the rapid development of China39。s economy, the demand for energy will increase increasingly. As China 39。s traditional coal is important energy security to promote the development of China39。s economic sustainable and healthy. The use of coal in the world after oil, belong to the world39。s secondlargest energy use. Is the main energy in our country, in a dominant in energy production and consumption. The modernization of our country is in the prehensive construction welloff society, the development of economy rapid growth in demand for coal. Entering the 21st century, with rapid development of science and technology, along with the development of science and technology of mechanical manufacturing technology have greater development. Scraper conveyor for coal mining face and roadway of coal mining machine is the largest coal usage and consumption is the most important equipment, is the first link in coal loading, largely determine productivity and efficiency in coal mining face. Has been widely used in engineering. It from it by the head, middle and tail three parts, etc. Working principle of scraper conveyor, will open chute, as coal, coal gangue or material, etc, under the scraper is fixed on the chain (of scraper chain), as a traction ponents. When the nose drive after startup, drive the head shaft on the chain wheel rotation, make the scraper chain run loop drive the material move along the chute, until to the nose of unloading. Scraper chain around sprocket for stepless closed cycle operation, plete material conveying. But because SGW 250 type scraper conveyor, there are many shortings, need further improvement, to further improve the efficiency of coal mining. It covers the design and manufacturing of sports conversion, power transmission, variable speed institutions, the design of the castings and forgings of mechanical design and technological content. I designed the double chain scraper conveyor, this paper first prehensive parison of the characteristics of various types of conveyor, according to the actual situation to choose the double chain scraper conveyor. Then, after half year thinking to delve into the side of the double chain scraper conveyor has carried on the overall structural design. Central to the nose gear, tanks, tank, scraper, scraper, chain sprocket, the tail and main ponents of the technical analysis and structure design, pleted the overall design of scraper conveyor. The design of the scraper conveyer is the feature of coal space is large, energy consumption is small, has a strong adaptability.目錄 、系列 31齒輪減速器的優(yōu)化設(shè)計3．2　機(jī)械傳動裝置的傳動方案的設(shè)計3．3 計算傳動裝置的運(yùn)動、動力參數(shù)3．4 錐齒輪的設(shè)計、校核及繪制3．5 斜齒輪的設(shè)計、校核及繪制3．6 輸入軸的結(jié)構(gòu)設(shè)計，校核 刮板輸送機(jī)結(jié)構(gòu)的基本要求 機(jī)頭部 機(jī)頭架 減速器 盲軸 電動機(jī)與減速器的聯(lián)接 電動機(jī) 機(jī)尾部 中部槽及附屬部件 運(yùn)輸能力 圓環(huán)鏈的選擇計算 圓環(huán)鏈鏈環(huán)的結(jié)構(gòu)和規(guī)格 圓環(huán)鏈接鏈環(huán)的結(jié)構(gòu)型式 圓環(huán)鏈鏈輪的齒形參數(shù)和幾何計算 圓環(huán)鏈鏈輪的齒形參數(shù) 圓環(huán)鏈和鏈輪的嚙合特性 圓環(huán)鏈和鏈輪的嚙合分析 圓環(huán)鏈和鏈輪的出點(diǎn)嚙合特性 實(shí)現(xiàn)入點(diǎn)嚙合的設(shè)計要求 圓環(huán)鏈鏈輪的技術(shù)條件 圓環(huán)鏈鏈輪的材料和熱處理 圓環(huán)鏈鏈輪的工藝技術(shù)要求 刮板 結(jié)構(gòu)型式的確定 外形尺寸的確定參考文獻(xiàn)謝辭刮板輸送機(jī)是一種以撓性體為牽引機(jī)構(gòu)的連續(xù)輸送機(jī)械，是為采煤工作面和采區(qū)巷道運(yùn)煤布置機(jī)械，是目前長壁式采煤工作面唯一的運(yùn)輸設(shè)備。可用于水平運(yùn)輸，亦可用于傾斜運(yùn)輸。沿傾斜向上運(yùn)輸時，煤層傾角不得超過25176。，向下運(yùn)輸時，傾角不得超過20176。，當(dāng)煤層傾角較大時，應(yīng)安裝防滑裝置?？蓮澢伟遢斔蜋C(jī)允許在水平和垂直方向作2176?！?176。
