传统振动式压路机的工作原理,系依靠装置于前轮心轴上的偏心块,以高速、垂直的正压力,作用在被压层及其底层上,加以压实。德国生产的振荡式新型压路机,凭藉一对同步、反向旋转的偏心块所产生的双向剪力,使被压层得以压实。振荡式新型压路机,前轮有3根轴,在心轴的上下180°对称处的两根轴上,分别设置偏心块。中心轴 The working principle of the traditional vibratory roller depends on the eccentric block installed on the front wheel mandrel, which acts on the pressed layer and its bottom layer with high speed and vertical positive pressure to compact it. The new oscillating roller manufactured in Germany uses a bidirectional shear force generated by a pair of synchronous and counter-rotating eccentric blocks to compact the pressed layer. The new oscillating roller includes three shafts on the front wheel, and two eccentric shafts are respectively arranged on two shafts at the symmetry position of the mandrel. The central axis
