一台YZ20JC型振动压路机,在工作中经常出现侧传动驱动齿轮被打坏的现象,致使机器的行走方向突然跑偏,并伴有清脆的敲击声。紧急停机检查时发现,驱动齿轮轴压盖破裂引起轴位移,造成驱动齿轮齿尖被打坏,因而无法正常啮合,从而发出敲击声。 我们曾多次更换驱动齿轮和焊修驱动齿轮轴压盖,但均未能解决问题。最后,通过现场跟踪观察,发现压盖一旦出现裂纹其固定螺栓立刻就会折断,驱动齿轮轴就产生位移。仔细观察后发现,压
A YZ20JC-type vibratory roller, the work side of the drive gear is often broken side of the phenomenon, resulting in a sudden departure of the direction of the machine running, accompanied by crisp percussion. Emergency shutdown inspection found that the drive gear shaft gland rupture caused by shaft displacement, resulting in drive gear tooth tip was broken, and therefore can not be properly engaged, which issued a percussion sound. We have changed drive gears and drive gear shaft glands many times, but none of them solved the problem. Finally, through the on-the-spot observation, it was found that once the gland cracks, the fixing bolt will be broken immediately, and the driving gear shaft will be displaced. After careful observation found that pressure
