The main parameter of this time design is to give bucket capacity:1m3 .This the main design scoop out machine of work device, the turn-over drives device, the liquid presses to spread to move principle. In the design, I adopted car dish and take in to change a work inside the larger scope, because of build to satisfy a request, upper parts turning set is a whole turn-over type, so it can Be adopting a liquid to press to spread to move control but canning make the whole machine function improve.Scoop out machine with machine type mutually through, the its excavation machine dint raised a lot of, the whole machine quality is about 26 ton, the excavation dint 140 KN, unload height about 4.59 m, the excavation depth 5.089 m, scoop out a radius 9.075 m.Keyword: the liquid press to scoop out machine; the liquid presses a control; the liquid presses system; whole turn-overs; unload; bucket.目 錄1 概述11.1 機(jī)械發(fā)展的特點(diǎn) 11.2 挖掘機(jī)械的類型 21.3 單斗液壓挖掘機(jī)的基本組成和工作原理 21.4 本次設(shè)計(jì)任務(wù) 22 設(shè)計(jì)方案32.1 工作裝置方案設(shè)計(jì) 32.1.1 工作裝置設(shè)計(jì)原則 32.1.2 反鏟裝置的組成及構(gòu)造特點(diǎn) 3 2.1.3 具體結(jié)構(gòu)方案 42.2 回轉(zhuǎn)機(jī)構(gòu)方案設(shè)計(jì) 52.2.1 對(duì)回轉(zhuǎn)機(jī)構(gòu)的基本要求 52.2.2 回轉(zhuǎn)機(jī)構(gòu)的選擇 52.2.3 制動(dòng)器的選擇 62.3 液壓系統(tǒng)方案設(shè)計(jì) 62.3.1 單斗液壓挖掘機(jī)的作業(yè)過(guò)程包括下列幾個(gè)間歇?jiǎng)幼?62.3.2 對(duì)液壓系統(tǒng)的要求 63 工作裝置設(shè)計(jì)計(jì)算 73.1 尺寸估計(jì) 73.2 運(yùn)動(dòng)分析 83.2.1機(jī)構(gòu)自身幾何參數(shù) 83.2.2 動(dòng)臂的運(yùn)動(dòng) 83.2.3 斗桿的運(yùn)動(dòng)12 3.2.4 鏟斗的運(yùn)動(dòng)133.3 工作裝置的設(shè)計(jì)計(jì)算143.3.1 斗形參數(shù)選擇143.3.2 轉(zhuǎn)斗挖掘阻力計(jì)算143.3.3 動(dòng)臂機(jī)構(gòu)參數(shù)的選擇153.3.4 鏟斗機(jī)構(gòu)的參數(shù)選擇203.3.5 鏟斗機(jī)構(gòu)載荷分析213.3.6 斗桿機(jī)構(gòu)的參數(shù)選擇223.3.7 動(dòng)臂液壓缸，斗桿液壓缸，鏟斗液壓缸初步設(shè)計(jì)估算244 回轉(zhuǎn)裝置設(shè)計(jì)計(jì)算 254.1 滾動(dòng)軸承式回轉(zhuǎn)支承的選型計(jì)算254.2 回轉(zhuǎn)起動(dòng)力矩和制動(dòng)力矩計(jì)算314.3 行星減速器設(shè)計(jì)324.3.1 齒形及精度334.3.2 齒輪材料及其性能334.3.3 計(jì)算傳動(dòng)比334.3.4 分配傳動(dòng)比334.3.5 高速級(jí)設(shè)計(jì)計(jì)算344.3.6 低速級(jí)的計(jì)算454.3.7 軸的設(shè)計(jì)475 轉(zhuǎn)臺(tái)布置和整機(jī)穩(wěn)定性 475.1 轉(zhuǎn)臺(tái)布置475.2 整機(jī)穩(wěn)定性計(jì)算486 液壓系統(tǒng)設(shè)計(jì) 506.1 液壓系統(tǒng)基本回路506.2系統(tǒng)初步計(jì)算和液壓元件的選用54結(jié)論56參考文獻(xiàn)57致謝58
