一台LX1000型路面铣刨机在工作一段时间后,其上链条张紧机构的张紧板出现严重磨损(见图1),经分析,链条与张紧板之间存在的滑动摩擦是造成张紧板损坏的主要原因;同时,张紧板的反作用力也阻止了链条的运转,并消耗掉一部分能量,加速了张紧板的损坏。 为此,我们将该结构做了改进,改进后的结构如图 A LX1000 pavement milling machine after working for a period of time, the tension of the tensioning mechanism on the chain tensioner appear severe wear (see Figure 1), the analysis of the existence of the friction between the chain and the tensioning plate is caused by Zhang At the same time, the reaction force of the tension plate also prevents the operation of the chain and consumes a part of energy, accelerating the damage of the tension plate. To this end, we have made improvements to the structure, the improved structure shown in Figure
