轮胎式压路机传动系统和变速箱设计 摘要 压路机在机械工程中属于道路设备的范围，广泛用于高级公路、铁路、机尝大坝、体育场等大型工程项目内容的填方压实作业，可以碾压沙性、半粘性及粘性土壤、路基稳定土及沥青混凝土路面层。使施工体具有足够的强度和稳定性，并能承受足够的载荷和抗侵蚀的能力，不会因为材料的自重和受环境影响等侵蚀。而轮胎式压路机在现在的市场上更加能够具有相当大的竞争优势，轮胎式压路机不会破坏已经施工的路面，轮胎压路机属超重型自行式静作用压路机，具有强大的静压力和优越的压实性能，适用于压实沥青路面、基础层、次基础层及填方工程，广泛用于各种交通道路、机场港口、大坝等大型工程的压实作业。轮胎压路机是一种静作用压路机，它是由特别制作的充气轮胎对地面施以搓揉压实作用，能获得平整而且致密的道路表面而且轮胎式压路机灵活性强，可移动性能比较好，适用范围广，在以后压路机械中具有很大的前景，本课题研究方向是主要对轮胎式压路机的传动系统与变速箱进行设计和计算，设计内容主要有选择传动轴和齿轮和确定参数以及对其进行校对。 关键词：压路机；传动系统；变速箱 Abstract The road roller i
