液压挖掘机行走装置设计

AbstractThe progress of reform and opening up has greatly widened the machinery industryin our country,and the gap between excavator-related production and manufacturingtechnologies and the world is narrowing day by day.Excavators are widely used inconstruction fields such as roads,mining areas,houses,tall statues and other fields.With the development of economic science and technology,excavators are playing anincreasingly important role.Among the power device,walking device and working device,the walking deviceis designed in this topic.On this basis,the crawler-type hydraulic excavator travelingdevice including "four wheels and one belt",reducer assembly,frame,tensioningmechanism and other parts are designed,the development status of hydraulic excavatorat home and abroad is introduced,the reasons for backward development are analyzed,the key parts are introduced,the selection and design calculation are carried out.Key words:machinery Walking Device of Hydraulic Excavator
