2013届本科生毕业设计（论文） 课题名称YZ16全液压振动压路机传动系统设计 专 业 机械设计制造及其自动化 专业方向 机械制造工艺及设备 班 级 091021B2 学 号 0910211412 学生姓名 吴佳毅 指导教师 纪林章 教研室 机械电子工程 上海应用技术学院机械工程学院 2013年9月28日 振动压路机是利用其自身的重力和振动压实各种建筑和筑路材料。在公路建 设中，振动压路机最适宜压实各种非粘性土壤、碎石、碎石混合料以及芥种沥青 混凝土而被广泛应用。B前国产振动压路机以中小吨位和机械传动方式为主，而 性能优良的全液压重型振动压路机主耍依赖于进口。之所以出现处于这种状况是 由于全液压压路机液压传动系统结构比较复杂并II各类液压元件加工复杂，为彻 底改变这种现状本文对现有压路机液压系统进行调研，研制出结构优良的全液压 压路机传动系统。 木文在理论分析和计算的基础上，完成了 YZ16型振动压路机液压系统的设 计，在方案、结构和设计方法上进行了创新：采用全液压的传动方案，通过3 个相互独立的液压回路实现行驶、振动和转向三大基木功能，与机械传动相比在 压实效果、爬坡能力、质量分配、操作控制和整体布局方面具备更大优势。转向 结构采用铰接式车架折腰转向的方案，转弯半径小、机动性好、前后轮迹重叠、 重心低、驾驶员视野开阔。同时本文对分动箱的机构进行了详细的设计计算，为 缩小分动箱的体积本次采用齿面硬度达60HRC的齿轮和双列滚柱轴承的结构。 关键词：振动压路机；设计：液压系统；分动箱 Abstract Vibratory roller is to use its own gravity and vibration compaction variety of building and road construction materials . In highway construction, the most suitable vibratory roller compacted variety of non- cohesive soils，gravel，crushed stone and a variety of asphalt concrete mixture has been widely used . Current domestic vibratory roller to small and medium tonnage and mechanical transmission mode based, and excellent performance heavy-duty hydraulic vibratory roller mainly dependent on imports. The reason why this situation is due in full hydraulic roller hydraulic system structure is more complex and complicated processing all types of hydraulic components 5 to completely change the situation this roller hydraulic system on the existing research，developed a well-structured full hydraulic roller transmission . Based on the theoretical analysis and calculation，based on the completed YZ16 type vibratory roller hydraulic system design, program，structure and design methods on the innovation : the use of full hydraulic transmission scheme by three independent hydraulic circuits to achieve with，vibration and steering three basic functions， compared with mechanical transmission in the compaction effect，climbing ability， quality and distribution，operation control and overall layout has a greater advantage.
