1.驱动桥常见故障(1)异响零部件质量不合格、主传动在装配时安装和调整不当,以及使用中磨损过甚等,都会使装载机在行驶和作业中发出异响。一般情况下,异响随机器速度的增加而增大。一般有以下几种异响:①主、被动齿轮啮合间隙不当发出异响。其原因及现象有:若主、被动齿轮啮合间隙过大,引起轮齿间相互撞击,响声为无节奏的“咯噔、咯噔”声;若啮合间隙过小,使轮齿之间相互挤压,响声为连续的“嗷嗷”声,并伴有驱动桥发热;若啮合间隙不 1. Drive axle common fault (1) abnormal sound quality parts failed, the main drive assembly and adjustment in the improper assembly, as well as wear and tear in use and so on, will make loaders in the driving and operating abnormal sound. In general, anomalies increase with machine speed. Generally have the following types of abnormal sound: ① Lord, passive gear meshing abnormal sound issued abnormal. The reasons and phenomena are: If the main and passive gear meshing gap is too large, causing the collision between gear teeth, the sound is rhythmic “slightly grateful, slightly grateful ” sound; if the meshing gap is too small, so that the teeth between each other Pressure, sound for continuous “嗷 嗷 ” sound, and accompanied by the drive axle fever; if the engagement gap is not
