中國(guó)礦業(yè)大學(xué) 2008 屆本科生畢業(yè)設(shè)計(jì) 第 1 頁(yè)橋式轉(zhuǎn)載機(jī)橋式轉(zhuǎn)載機(jī)是綜合機(jī)械化采煤工作面運(yùn)輸系統(tǒng)配套設(shè)備中的重要組成部分,在工作面運(yùn)輸巷中接受工作面刮板輸送機(jī)卸下的煤流,不停頓地轉(zhuǎn)運(yùn)到可伸縮帶式輸送機(jī)上去.橋式轉(zhuǎn)載機(jī)與工作面刮板輸送機(jī)機(jī)頭部同步推移,保證工作面采煤機(jī)連續(xù)采煤,實(shí)現(xiàn)綜采工作面的高產(chǎn)高效作業(yè).橋式轉(zhuǎn)載機(jī)是一種特殊結(jié)構(gòu)的刮板輸送機(jī),其動(dòng)力傳動(dòng)系統(tǒng)及驅(qū)動(dòng)裝置與刮板輸送機(jī)相似,其機(jī)身有一個(gè)坡道段和一段拱橋結(jié)構(gòu),可在帶式輸送機(jī)機(jī)尾段上面搭接.在后退式采煤工作面運(yùn)輸巷中,當(dāng)轉(zhuǎn)載機(jī)推移到其拱橋段全部與帶式輸送機(jī)機(jī)尾段搭接疊的極限位置時(shí),可伸縮帶式輸送機(jī)縮短一個(gè)搭接長(zhǎng)度,帶式輸送機(jī)的機(jī)發(fā)展部移置到轉(zhuǎn)載機(jī)卸載機(jī)頭下方,轉(zhuǎn)載機(jī)又可隨工作面的推進(jìn)而向前推移.轉(zhuǎn)載機(jī)是與大型綜采工作面設(shè)備配套使用的順槽輸送、轉(zhuǎn)載設(shè)備，完成把工作面輸送機(jī)送來(lái)的煤輸送、轉(zhuǎn)運(yùn)到后續(xù)皮帶輸送設(shè)備上的任務(wù),并提供相應(yīng)的連接手段。設(shè)計(jì)要求與ZY2300 皮帶機(jī)自移機(jī)尾配套，以實(shí)現(xiàn)在2.3 米范圍內(nèi)整體移動(dòng)而不必拆移皮帶機(jī)。與ZY2300 皮帶機(jī)自移機(jī)尾配合可更方便地調(diào)節(jié)皮帶機(jī)，增強(qiáng)了皮帶機(jī)與轉(zhuǎn)載機(jī)配合的協(xié)調(diào)性。本轉(zhuǎn)載機(jī)與SGZ1000/3000 型輸送機(jī)配套使用，運(yùn)量可達(dá)4000 噸/小時(shí)，技術(shù)先進(jìn)，工作可靠，是大型綜采配套設(shè)備的優(yōu)秀機(jī)型。中國(guó)礦業(yè)大學(xué) 2008 屆本科生畢業(yè)設(shè)計(jì) 第 2 頁(yè)Bridge reversed loaderBridge reversed loader is a reprint of fully coal face ancillary equipment in the transport system an important part of the roadway in the face of the accepted face scraper conveyor unloading of coal flow, not halt the transfer to the retractable belt Conveyor boost. Bridge reversed loader with the face-scraper conveyor machine synchronous over his head, face Shearer guarantee for coal mining, and fully mechanized coal face of high yield and high efficiency operations.Bridge reversed loader is a reprint of a special structure of the scraper conveyor, powertrain and drive and scraper conveyor similar to a ramp of its fuselage and a section of the arch bridge structure and belt conveyors in the tail Paragraph above lap. In the back-alley in the coal face when the machine goes to reprint its arch bridge and all of the aircraft ended the lap belt conveyor stack of position limits, a retractable belt conveyor shortened ride Next length of the belt conveyor for the development of the shift to home-unloading nose reproduced below, can be reproduced with the face of the advance goes forward.Reproduced large-scale machine is fully coal face with the equipment supporting the use of the Gate transmission, reproduced equipment, to complete the face conveyor sent to the coal transportation, transit facilities to follow up on the conveyor belt of tasks and to provide the appropriate means of connection. ZY2300 belt with the design requirements for supporting the tail since the shift to achieve in the 2.3 metres of the overall mobile rather than demolished shift belt machine. ZY2300 belt and the tail of the shift can be more easily cope with belt-regulation, enhance the belt-and-reproduced with the coordination. This reprint of SGZ1000/3000 and supporting the use of conveyor, capacity up to 4,000 tons / hour, technologically advanced, reliable, large-scale comprehensive mining equipment supporting the excellent models.中國(guó)礦業(yè)大學(xué) 2008 屆本科生畢業(yè)設(shè)計(jì) 第 3 頁(yè)目 錄1 概述 .11.1轉(zhuǎn)載機(jī)的發(fā)展概況 .11.2國(guó)內(nèi)外轉(zhuǎn)載機(jī)的技術(shù)特點(diǎn)及趨勢(shì) .11.3 轉(zhuǎn)載機(jī)組成 .31.4 限矩型液力聯(lián)軸器的選擇 61.4.1 液力聯(lián)軸器的工作液體 .72總體方案的確定 72．1 結(jié)構(gòu)與傳動(dòng)系統(tǒng) .72．1．１主要技術(shù)參數(shù) .102.2電動(dòng)機(jī)的選擇 102.3總傳動(dòng)比及傳動(dòng)比的分配 .102.3.1 總傳動(dòng)比的確定 112.3.2 傳動(dòng)比的分配 .113 傳動(dòng)系統(tǒng)的設(shè)計(jì) 113.1 各級(jí)傳動(dòng)轉(zhuǎn)速、功率、轉(zhuǎn)矩的的確定 .113.2 第一級(jí)錐齒輪傳動(dòng)設(shè)計(jì)計(jì)算 .133.2.1 選擇齒輪材料 133.2.2 按齒根的彎曲疲勞強(qiáng)度設(shè)計(jì)計(jì)算 .143.2.3 齒面的接觸疲勞強(qiáng)度校核 .163.2.4 齒輪幾何尺寸的計(jì)算 173.3 第二級(jí)直齒圓柱齒輪傳動(dòng)設(shè)計(jì)計(jì)算 .193.3.1 選擇齒輪材料 193.3.2 按齒根的彎曲疲勞強(qiáng)度設(shè)計(jì)計(jì)算 .213.3.3 齒面的接觸疲勞強(qiáng)度校核 .243.3.4 齒輪幾何尺寸的計(jì)算 253.4第三級(jí)直齒圓柱齒輪傳動(dòng)設(shè)計(jì)計(jì)算 .253.4.1 選擇齒輪材料 .253.4.2 按齒根的彎曲疲勞強(qiáng)度設(shè)計(jì)計(jì)算 .273.4.3 齒面的接觸疲勞強(qiáng)度校核 .303.4.4 齒輪幾何尺寸的計(jì)算 314 傳動(dòng)軸的結(jié)構(gòu)設(shè)計(jì)與校核 .31中國(guó)礦業(yè)大學(xué) 2008 屆本科生畢業(yè)設(shè)計(jì) 第 4 頁(yè)4.1 輸入軸的結(jié)構(gòu)設(shè)計(jì) 334.1.1 確定軸的最小直徑 .334.1.2 減速器高速軸 I 的設(shè)計(jì) .334.2 Ⅱ軸的結(jié)構(gòu)設(shè)計(jì) 384.2.1 確定軸的最小直徑 .384.2.2 按軸向定位要求確定各軸段直徑和長(zhǎng)度 .384.3Ⅲ軸的結(jié)構(gòu)設(shè)計(jì) .424.3.1 確定軸的最小直徑 424.3.2 按軸向定位要求確定各軸段直徑和長(zhǎng)度 .424．4 輸出軸的結(jié)構(gòu)設(shè)計(jì) .454.4.1 確定軸的最小直徑 .454.4.2 按定位要求確定各軸段直徑和長(zhǎng)度 .455 鍵的校核 .485.1 Ⅰ軸鍵的校核 .485.2Ⅱ軸鍵的校核 .485.3Ⅲ軸鍵的校核 .495.4Ⅳ軸鍵的校核 .496 軸承的校核 .506.1驗(yàn)算Ⅰ軸承壽命 .506.2驗(yàn)算Ⅱ軸承壽命 .516.3驗(yàn)算Ⅲ軸承壽命 .516.4驗(yàn)算Ⅳ軸承壽命 .526.5箱體及附件的設(shè)計(jì) .537 安裝、使用和維護(hù) 547.1 安裝和拆卸 .547.1.1 安裝方法 .547.1.2 拆卸方法 557.2操作及運(yùn)轉(zhuǎn) .55參考文獻(xiàn) 57外文翻譯： 58英文原文： .58中文譯文 69中國(guó)礦業(yè)大學(xué) 2008 屆本科生畢業(yè)設(shè)計(jì) 第 5 頁(yè)結(jié) 論 .77致 謝 .78
