汽車起重機起升機構(gòu)和液壓系統(tǒng)的設(shè)計
摘要
本設(shè)計介紹了汽車液壓起重機的工作原理，并詳細介紹了起升機構(gòu)設(shè)計計算的全過程，其中包括起升機構(gòu)的工作原理，參數(shù)確定，結(jié)構(gòu)設(shè)計等。該設(shè)計汽車起重機的起升機構(gòu)采用定量高速液壓馬達，減速器，制動器，聯(lián)軸器及卷筒組成。根據(jù)液壓系統(tǒng)的技術(shù)指標(biāo)對該系統(tǒng)進行整體方案設(shè)計，對其功能和工作原理進行分析，初步確定了系統(tǒng)各回路的基本結(jié)構(gòu)及主要元件，按照所給機構(gòu)性能參數(shù)和液壓性能參數(shù)進行元件的選擇計算，以滿足該起重機所要達到的要求。
