工程机械运行时会产生振动,本文指的是非正常振动(以下简称振动)。这是常见的故障,它会加速零件的损坏(如螺钉松动、轴承咬死、焊缝开裂、仪表失灵等),且使噪音增大,致使司机疲劳。振动严重的,甚至会造成机械事故和人身事故。现试对工程机械振动原因和对策,发表一点浅见,仅供同行参阅。一、振动原因分析常见的引起工程机械振动的原因如图一所示。
When the construction machinery is running, it will produce vibration. This article refers to abnormal vibration (hereinafter referred to as vibration). This is a common failure, it will accelerate the damage of parts (such as screw loosening, bearing seizure, cracking of welds, failure of the instrument, etc.), and make the noise increase, resulting in driver fatigue. Serious vibrations may even cause mechanical accidents and personal accidents. The current test gives a brief opinion on the causes and countermeasures of construction machinery vibration and is only for reference by the industry. First, the cause of vibration analysis Common cause of vibration of construction machinery is shown in Figure 1.
