1、河北建筑工程学院本科毕业设计（论文）题目ZL50装载机总体及行星变速箱设计（第二排行星架）全套图纸，加学科专业：机械设计制造及其自动化班级：机094姓名：指导教师：摘要Zl50装载机是我国轮式装载机系列中的中型产品，该机是一种较大型的以装卸散状物料为主的工程机械，广泛应用于矿山、基建、道路修筑、港口、货场、煤场等地进行装载、推土、铲挖、起重、牵引等作业。本设计的步骤简单如下：1.对装载机的总体进行分析，确定总体参数；2.牵引计算，确定出各档及各档传动比；3.对装载机进行整体布置，并绘出总体布置图；4.变速箱的设计，这是本设计中最主要的部分，确定传动比，

2、设计传动简图，配齿计算，得出齿圈、行星轮、太阳轮的齿数，并验算其合理性。然后进行齿轮设计；5.对离合器，轴、轴承的设计及选择。此设计中，主要任务是设计变速箱及第二行星排，设计中采用了行星式动力换挡变速箱，它具有3个离合器和3根轴，且轴安装在壳体内，使变速箱结构简单、便于维修。变速箱具有两个前进挡和一个后退档，可以产生三个速度。关键词：装载机液力机械传动系统行星式动力换挡变速箱TABSTRACTTheloaderZL50iswheeltypeanditismorebiggeramongtheseriesmadeinourcountry.Itissuita
