摘 要起重機(jī)是用來對(duì)物料做起重、運(yùn)輸、裝卸和安裝等作業(yè)的機(jī)械設(shè)備，它可以減輕體力勞動(dòng)、提高勞動(dòng)生產(chǎn)率和在生產(chǎn)過程中進(jìn)行某些特殊的工藝操作，實(shí)現(xiàn)機(jī)械化和自動(dòng)化。起升機(jī)構(gòu)包括電動(dòng)機(jī)、制動(dòng)器、減速器、卷筒和滑輪組。電動(dòng)機(jī)通過減速器，帶動(dòng)卷筒轉(zhuǎn)動(dòng)，使鋼絲繩繞上卷筒或從卷筒放下，以升降重物。本文就十噸橋式起重機(jī)起升機(jī)構(gòu)做設(shè)計(jì)計(jì)算，確定起升機(jī)構(gòu)傳動(dòng)方案，確定起升機(jī)構(gòu)工作級(jí)別，對(duì)起升機(jī)構(gòu)的主要部件卷筒、鋼絲繩、滑輪等鋼絲繩卷繞系統(tǒng)，電動(dòng)機(jī)、聯(lián)軸器、減速器等驅(qū)動(dòng)裝置進(jìn)行設(shè)計(jì)計(jì)算，驗(yàn)證卷筒壁壓應(yīng)力，卷筒應(yīng)力，確定吊鉤裝置構(gòu)造方案，吊鉤橫梁，滑輪軸的計(jì)算等。對(duì)起升機(jī)構(gòu)運(yùn)行的過程，包括起升速度、起升和制動(dòng)時(shí)間進(jìn)行計(jì)算和驗(yàn)算。關(guān)鍵詞：傳動(dòng)方案；卷繞系統(tǒng)；驅(qū)動(dòng)裝置；起升運(yùn)行 AbstractCrane is used to start heavy materials, transportation, handling and installation of machinery and equipment and other operations, which can reduce manual labor, improve labor productivity and in the production process for some special process operation, mechanization and automation. Lifting mechanism includes a motor, brake, reducer, drum and pulley. Motor through reducer, driving drum rotation, so that the wire rope around the drum or from a roll down to lift heavy loads.In this paper, ten tons crane hoisting mechanism to do the design calculations to determine the transmission scheme lifting mechanism, hoisting mechanism to determine the working level of the main components of the hoisting mechanism drum, wire rope, wire rope winding system pulleys, motors, United coupling, reducer drives the design calculations, validation reel wall stress, stress reel, hook device is configured to determine program, hook beams, pulley shaft calculation. Hoisting mechanism for running processes, including the lifting speed, lifting and braking time calculations and checking.Keywords: transmission scheme; winding system; drive; lifting operation目錄摘 要IIIAbstractIV目錄V1 緒論11.1 橋式起重機(jī)的簡(jiǎn)介11.2 起重機(jī)械的發(fā)展21.3 起重機(jī)械的特點(diǎn)22 起升機(jī)構(gòu)主要部件的設(shè)計(jì)計(jì)算42.1主要參數(shù)42.2確定起升機(jī)構(gòu)傳動(dòng)方案42.3 確定吊鉤和滑輪組52.4 鋼絲繩的計(jì)算62.4.1 鋼絲繩所受最大拉力62.4.2 鋼絲繩允許的偏斜角72.5 卷筒的計(jì)算82.5.1 卷筒材料82.5.2 卷筒直徑計(jì)算82.5.3 卷筒長(zhǎng)度82.5.4 卷筒壁壓應(yīng)力驗(yàn)算82.5.5 卷筒應(yīng)力驗(yàn)算92.6 繩端固定裝置的計(jì)算102.7 取物裝置122.7.1 確定吊鉤裝置構(gòu)造方案122.7.2 吊鉤主體結(jié)構(gòu)的主要尺寸的計(jì)算122.7.3 吊鉤強(qiáng)度驗(yàn)算132.7.4 吊鉤彎曲部分?jǐn)嗝鍭-A強(qiáng)度驗(yàn)算132.7.5 吊鉤彎曲部分?jǐn)嗝鍮-B強(qiáng)度驗(yàn)算142.7.6 推力球軸承的選擇142.7.7 吊鉤橫梁的計(jì)算152.7.8 滑輪軸的計(jì)算162.7.9 拉板的強(qiáng)度校核173 起升運(yùn)行機(jī)構(gòu)設(shè)計(jì)193.1 力矩的計(jì)算193.1.1 平穩(wěn)上升階段193.1.2 平穩(wěn)下降階段203.1.3 上升起動(dòng)階段203.1.4 下降制動(dòng)階段223.2 電動(dòng)機(jī)的選擇223.2.1 電動(dòng)機(jī)的功率確定223.2.2 驗(yàn)算電動(dòng)機(jī)發(fā)熱條件233.3 減速器的選擇233.3.1 減速器傳動(dòng)比233.3.2 減速器的選取233.3.3 輸出軸強(qiáng)度校核233.4 起升速度和實(shí)際所需功率243.4.1 實(shí)際速度243.4.2 實(shí)際功率243.5 制動(dòng)器的選擇243.6 起升和制動(dòng)時(shí)間驗(yàn)算253.6.1 起動(dòng)時(shí)間驗(yàn)算253.6.2 制動(dòng)時(shí)間驗(yàn)算263.7.1 疲勞計(jì)算263.7.2 強(qiáng)度驗(yàn)算274 總結(jié)與展望294.1 總結(jié)294.2 展望29致 謝30參考文獻(xiàn)31
