4m~3挖掘机履带装置上的主动轮,材质为ZG42CrMo。由于挖掘机移动频繁,主动轮一年即需更换一组(两个),因磨损导致折断报废的占99％。特别是挖掘机工作装置分散,更换就更费时费工。针对上述问题,首先核对履带板尺寸,在履带板与主动轮传动中不产生干涉的情况下,对原设计图纸进行局部改动(如图)。图中括号内数字为原设计尺寸。改进后,装机试验,一年多来运转正常,据现场测定,寿命可提高
4m ~ 3 excavator track drive on the device, made of ZG42CrMo. Due to frequent excavator movements, the active wheels need to be replaced one year (two), resulting in 99% of worn-out scrap. In particular, excavators scattered working equipment, replacement of more time-consuming and laborious. In response to the above problems, first check the track shoe size, in the track shoe and drive wheel without interference in the case of the original design drawings for local changes (Figure). Figure figures in brackets for the original design size. After the improvement, installed test, more than a year of normal operation, according to the field determination, life expectancy can be increased
