1、Xxxxx大學(xué)畢業(yè)設(shè)計工程鉆機(jī)—履帶行走部分設(shè)計摘要工程機(jī)械是國民經(jīng)濟(jì)建設(shè)及國防工程施工中使用的重要技術(shù)裝備，在國民經(jīng)濟(jì)建設(shè)中，尤其是城市建設(shè)、民用建筑、水利建設(shè)、道路構(gòu)筑、機(jī)場修建、礦山開采、碼頭建造、農(nóng)田改良中，工程機(jī)械起著越來越重要的作用。我國的工程機(jī)械行業(yè)目前進(jìn)入了一個高速發(fā)展階段，推、挖、裝、起重、鏟土運(yùn)輸、筑路、農(nóng)用機(jī)械等各種品種齊全并形成了系列化，各種工程機(jī)械雖然品種很多但基本上可劃分為動力裝置、行走裝置和工作裝置。履帶行走裝置的挖掘機(jī)履帶行駛系統(tǒng)包括車架。行走裝置和懸架三部分。車架是整體骨架，用來安裝所有的總成和部件。行走裝置用來支持機(jī)體，把
