7、置挖掘时的反力，使挖掘机稳定的支撑在地面工作，也是挖掘机在工作场地自由移位的装置。行走装置设计的好坏会影响挖掘机的机动性、爬坡能力、越野性能、接地比压以及挖掘机的稳定性等。【关键词】履带式，液压挖掘机，行走机构，张紧装置。前言改革开放以来，我国的科学技术、信息技术迅猛发展，各行各业都发生了翻天覆地的变化，工程机械行业同样得到了相应的快速发展。各行各业都在奋力拼搏、大胆创新，使得工程机械品种不断增加、产量不断提高、性能不断完善，发展势头强劲。-30-液压挖掘机是工程机械的一个重要品种，是一种广泛用于建筑、铁路、公路、水利、采

8、矿等建设工程的土方机械。它的发展与应用反映了一个国家施工机械化的水平。液压挖掘机由发动机、液压系统、回转机构、工作装置、底盘五部分组成。发动机的作用是提供动力；液压系统功能是把发动机机械能以油液为介质，利用油泵转变为液压能传送给油缸、马达等，再传动各个执行机构，实现各种运动；回转机构是实现转台的回转；工
