1、洛陽(yáng)理工學(xué)院(論文)WY6反鏟液壓挖掘機(jī)工作裝置設(shè)計(jì)摘要液壓挖掘機(jī)是土方和石方工程的主要施工機(jī)械，廣泛應(yīng)用于能源、交通、水利、城鎮(zhèn)建設(shè)以及現(xiàn)代化軍事工程等領(lǐng)域的機(jī)械化施工。液壓挖掘機(jī)利用工作裝置進(jìn)行土方和石方挖掘，工作裝置的性能和可靠性是整機(jī)先進(jìn)性的重要標(biāo)志。本設(shè)計(jì)對(duì)液壓挖掘機(jī)的典型工況進(jìn)行了分析，根據(jù)液壓挖掘機(jī)的工作特點(diǎn)，從幾何尺寸、動(dòng)力特性、結(jié)構(gòu)強(qiáng)度、經(jīng)濟(jì)性等方面討論了液壓挖掘機(jī)工作裝置的設(shè)計(jì)要求，提出了液壓挖掘機(jī)工作裝置的設(shè)計(jì)原則。通過(guò)分析挖掘機(jī)工作裝置鉸點(diǎn)的失效機(jī)理，提出了鉸點(diǎn)銷(xiāo)軸和軸套最小
2、間隙的計(jì)算公式和最大間隙的限制條件。同時(shí)以某挖掘機(jī)工作裝置為例，進(jìn)行了工作裝置的優(yōu)化設(shè)計(jì)。對(duì)比優(yōu)化設(shè)計(jì)和原設(shè)計(jì)尺寸，比較了主要作業(yè)參數(shù)，得出經(jīng)過(guò)優(yōu)化設(shè)計(jì)的鏟斗缸的挖掘力得到了充分發(fā)揮。關(guān)鍵詞液壓反鏟挖掘機(jī)；工作裝置；大臂運(yùn)動(dòng)分析；鏟斗II洛陽(yáng)理工學(xué)院(論文)DESIGNOFWORINGDEVICEOFBACKHOEHYDRAULICEXCAVATORAbstractHydraulicexcavatoristhemajorconstructionmachineintheearthmoving,exca
