YZ8H压路机振动轮设计
摘要
振动压路机是众多工程施工设备中的一种,其主要要用于压实各种土壤、碎石块以及各种沥青混凝土等。在公路施工中,主要用于路基、路面的压实,是修路施工中不可缺少的压实设备。根据振动压路机的结构特点、工作原理、操作方法和主要用途等的不同,可以分为不同的种类。按振动轮内部结构的不同可分为:振动、震荡和垂直振动。按振动型式又可分为:单频单幅、单频双幅、双频多幅、无级调频调幅等。由此可见,振动轮是振动压路机的核心。
我国的振动压路机的研究已经相对成熟,但是与国外发达国家相比仍然有很大的差距,本文主要研究的就是压路机振动轮的设计。
本设计简要介绍了振动压路机的发展概况、振动机构、激振器的结构、偏心块的设计与计算和减振块的设计计算,轴的设计与校核,轴承的寿命计算。
