I摘 要本文主要是針對(duì)雙軸直線振動(dòng)篩的設(shè)計(jì)進(jìn)行的，從整體布局到個(gè)別零件的選用都進(jìn)行了改良，包括篩箱，篩面的設(shè)計(jì)和固定，激振器的形狀，支撐方案的設(shè)計(jì)等等，還包括軸，齒輪，帶輪，偏心塊等零件的設(shè)計(jì)。采用單電機(jī)帶動(dòng)，齒輪傳動(dòng)來(lái)使得兩個(gè)偏心塊同步，另一方面采用用了座式結(jié)構(gòu)，淘汰了以往懸掛式的方式，使得結(jié)構(gòu)更加安全，占地面積更小。本產(chǎn)品為生產(chǎn)能力為 80t/h 的大型振動(dòng)篩，對(duì)于篩框的材料有比較高的要求，現(xiàn)采用高強(qiáng)度和高沖擊韌性的鋼材，不僅僅提高了篩框的耐用度，還減輕了整個(gè)結(jié)構(gòu)的重量，對(duì)彈簧的選則等許多方面也帶來(lái)了很多的方便。設(shè)計(jì)中還包括對(duì)連接和固定件的選用，采用耐用的十字軸聯(lián)軸器，并用螺栓連接代替焊接，減小了焊接時(shí)應(yīng)力對(duì)它的影響。還包括對(duì)產(chǎn)品的潤(rùn)滑，以及保養(yǎng)等日常維護(hù)措施。關(guān)鍵詞： 振動(dòng)篩 激振器 偏心塊 橫梁 IIAbstractThis article is carried out mainly according to the design of the two axle vibrating separators of straight line, from overall layout go to individual element choose to go on improving , include sifting the design of case and compass screen surface and the regular shape of vibrator , support the design of scheme and so on , still include the design of the elements such as axle, gear, belt and partial piece. Drive with single generator, positive drive makes two partial pieces synchronous , has adopted on the other hand to use type structure, have superseded the way of former overhead suspension, make structure more safe, it is less to cover an area of area.This design product has higher requirement, for the material of screen frame for productivity is the large scale vibrating separator of 80 t/h, has now not only raised the durability of screen frame with the high-strength and high steel material of impact tenacity, have still alleviated the weight of entire structure, for spring choose to have also brought many conveniences.In design still include for connection and regular choosing, with the durable shaft coupling of cross axle, replace welding with bolt connection, it is little to reduce welding stress for it's influence. In this design, include the lubrication for product as well as the daily maintenance measures such as maintenance.Keyword: Vibrating separator, vibrator, partial piece, beam 1目 錄摘 要 ⅠAbstract Ⅱ第 1 章 緒論 11.1 課題研究背景及意義 11.2 振動(dòng)篩的發(fā)展史 11.3 振動(dòng)篩在國(guó)內(nèi)外的發(fā)展現(xiàn)狀 21.4 振動(dòng)篩在實(shí)際生產(chǎn)中的應(yīng)用 31.5 振動(dòng)篩的工作原理、分類及特點(diǎn) 41.5.1 振動(dòng)篩的工作原理 41.5.2 直線振動(dòng)篩的工作原理 4第二章 總體方案的確定 72.1 直線式振動(dòng)篩的選擇 72.2 篩箱的設(shè)計(jì) 72.2.1 篩箱部件的連接 82.2.2 篩箱的支撐 82.2.3 篩框的材質(zhì) 82.3 篩面的設(shè)計(jì) .92.3.1 篩面種類 92.3.2 篩面的固定 .102.3.2.1 木楔壓緊 .102.3.2.2 拉鉤張緊 .1122.3.2.3 螺栓壓緊 .112.3.2.4 斜板壓緊 .112.4 激振器 .122.5 支撐形式與隔振裝置 .13第三章、雙軸直線振動(dòng)篩的設(shè)計(jì)計(jì)算 143.1 振動(dòng)篩上物料的運(yùn)動(dòng)分析和工藝參數(shù)的選擇 .143.1.1 直線振動(dòng)面上的物料運(yùn)動(dòng)分析 .143.1.1.1 篩面的運(yùn)動(dòng)方程 .143.1.1.2 物料的運(yùn)動(dòng)分析 .143.1.1.3 拋擲指數(shù) vK的討論 153.1.2 工藝參數(shù)的選擇 .163.1.2.1 處理量要求 .183.1.2.2 拋射強(qiáng)度 vK的確定 183.1.2.3 振動(dòng)篩的振幅 A 的確定 .183.1.2.4 篩面傾角 ?.193.1.2.5 振動(dòng)方向角 ?.193.1.2.6 篩下物最大顆粒 .193.1.2.7 物料層厚度 203.1.2.8 篩分方式 .203.2 總體設(shè)計(jì)計(jì)算步驟 .203.2.1 計(jì)算振動(dòng)篩篩面面積 .203.2.2 振動(dòng)次數(shù)的計(jì)算 .2033.2.3 物料運(yùn)動(dòng)速度的計(jì)算 .203.2.4 驗(yàn)算生產(chǎn)率 .213.2.5 估算振動(dòng)篩的重量 .213.2.6 激振器偏心塊的質(zhì)量及其偏心距的確定 .213.2.7 隔振彈簧剛度的確定 .213.2.8 篩箱的設(shè)計(jì) .213.2.9 電動(dòng)機(jī)的選擇 .223.3 壓縮彈簧的設(shè)計(jì) .223.3.1 初算彈簧所承受的載荷 .233.3.2 彈簧材料和直徑 .233.3.3 彈簧的剛度和變形計(jì)算 .233.3.4 彈簧的校核 .243.3.5 結(jié)構(gòu)參數(shù)的計(jì)算 .263.3.6 疲勞強(qiáng)度校核 .263.3.7 穩(wěn)定性計(jì)算 .273.4 齒輪的設(shè)計(jì) .273.4.1 選定齒輪類型，精度等級(jí)，材料及齒數(shù) 283.4.2 按齒面接觸強(qiáng)度計(jì)算 .283.4.3 計(jì)算載荷系數(shù) .283.4.4 計(jì)算模數(shù) .293.4.5 齒輪的設(shè)計(jì)計(jì)算 .293.5 軸的計(jì)算與設(shè)計(jì) .30 43.5.1 初步估算軸的最小直徑 .313.5.2 軸的各段長(zhǎng)度的直徑設(shè)計(jì) .313.5.3 對(duì)軸的受力分析 .313.6 圓軸法蘭的設(shè)計(jì) .333.7 軸承壓蓋的設(shè)計(jì)計(jì)算 .343.8 密封件的設(shè)計(jì)計(jì)算 .353.9 偏心塊的設(shè)計(jì)與計(jì)算 .363.10 聯(lián)軸器的設(shè)計(jì) 363.10.1 聯(lián)軸器的類型選擇 373.10.2 規(guī)格的選擇與計(jì)算 373.11 鍵的選擇 373.11.1 軸與偏心塊連接處鍵的選擇 373.11.2.1 電動(dòng)機(jī)與帶輪的連接處鍵的尺寸 373.12 螺栓的強(qiáng)度校核 383.12.1 橫聯(lián)合梁與篩板連接處螺栓的強(qiáng)度校核 383.13 帶輪的設(shè)計(jì)計(jì)算 383.13.1.確定計(jì)算功率 CAP.393.13.2 計(jì)算帶的速度 393.13.3 確定 v 帶的基準(zhǔn)長(zhǎng)度和傳動(dòng)中心距 393.13.4 確定帶的根數(shù) z 403.13.5 計(jì)算預(yù)緊力 0F40第四章 日常維護(hù)保養(yǎng)以及故障排除 .4254.1 日常維護(hù)保養(yǎng) 424.2 潤(rùn)滑 434.3 檢修周期以及大小修 434.4 故障分析以及排除 44結(jié)論 45附錄一 目前篩分機(jī)的分類形式 .46參考文獻(xiàn) 48謝詞 49
