【正文】 本科畢業(yè)設(shè)計(jì)（論文） 題目： 液壓千斤頂設(shè)計(jì) 教學(xué)單位： 機(jī)電工程系 專 業(yè)： 機(jī)械設(shè)計(jì)制造及其自動(dòng)化 學(xué) 號(hào)： 0912020239 姓 名： 劉 健 指導(dǎo)教師： 2020 年 5 月 I 摘 要 液壓傳動(dòng)的基本原理是機(jī)械能與液壓能的相 互轉(zhuǎn)換，液壓千斤頂是典型的利用液壓傳動(dòng)的設(shè)備，液壓千斤頂具有結(jié)構(gòu)緊湊、體積小、重量輕、攜帶方便、性能可靠等優(yōu)點(diǎn)，被廣泛應(yīng)用于流動(dòng)性起重作業(yè)，是維修汽車、拖拉機(jī)等理想工具。其結(jié)構(gòu)輕巧堅(jiān)固、靈活可靠，一人即可攜帶和操作，千斤頂是用剛性頂舉件作為工作裝置，通過(guò)頂部托座或底部托爪在小行程內(nèi)頂升重物的輕小起重設(shè)備。 關(guān) 鍵 詞 : 液壓傳動(dòng) 工作原理 故障 維護(hù) II Abstract Hydraulic drive is to liquid pressure can for work of drive way ， its work principle is machinery can and hydraulic can of mutual conversion, hydraulic jack is typical of using hydraulic drive of device, hydraulic jack has structure pact, and volume small, and weight light, and carry easy, and performance reliable, advantages, is widely application Yu liquidity lifting job, is maintenance car, and tractor, ideal tools. Its light structure strong and flexible and reliable, one person to carry and operate, Jack is made of rigid toplift as a work device, through the bracket at the top or bottom bracket feet lifting heavy weights in the small tour of small light lifting equipment. Key words: Hydraulic drive 。 operating principle 。 broken down 。 maintain III 目錄 第 1 章 緒論 ...........................................................................................................................1 第 2 章 液壓千斤頂?shù)慕Y(jié)構(gòu)及組成 ...........................................................................................2 液壓千斤頂?shù)慕Y(jié)構(gòu)圖 .................................................................................................2 液壓千斤頂?shù)慕M成 .....................................................................................................2 液壓傳動(dòng)的優(yōu)缺點(diǎn) .....................................................................................................3 液壓傳動(dòng)的優(yōu)點(diǎn) .................................................................................................3 液壓傳動(dòng)的缺點(diǎn) ...............................................................................................3 液壓千斤頂?shù)脑? .....................................................................................................4 液壓千斤頂原理圖 ...........................................................................................4 液壓千斤頂?shù)奶攸c(diǎn) ...........................................................................................5 第 3 章 液壓千斤頂結(jié)構(gòu)設(shè)計(jì) ..................................................................................................6 大液壓缸設(shè)計(jì) ............................................................................................................6 液壓缸主要參數(shù)及尺寸的確定 ............................................................................7 相關(guān)計(jì)算及驗(yàn)證 .................................................................................................7 液壓缸的推力和流量計(jì)算 ...................................................................................8 大液壓缸的流量計(jì)算 ..........................................................................................8 小液壓缸的設(shè)計(jì) ........................................................................................................9 缸底厚度的計(jì)算 ...............................................................................................9 小液壓缸的推力計(jì)算 ...................................................................................... 10 小液壓缸的流
