有一台IPF-85B混凝土泵车,底盘型号为SJR461。该车在泵送混凝土时,发生分动箱无动力输出而造成液压泵不工作的故障。经拆检,是分动箱第一轴和第二轴之间支承的有保持架滚针轴承损坏,保持架被打成碎片,滚针脱出掉入分动箱底部但没有损伤。由于保持架全部损坏,轴承型号无法查找,欲用国产同类轴承替换,但尺寸或大或小均不适用,而进口轴承又需等4～6个月。 为此,我们采取加工滚针的办法进行修复。修复方法是:将加工好的滚针与原滚针相间依次用黄油粘结
There is an IPF-85B concrete pump truck with chassis type SJR461. The car in the pumping of concrete, the transfer case occurs without power output hydraulic pump does not work failure. After dismantling, there is a cage bearing fault between the first shaft and the second shaft of the transfer case, the cage is broken into pieces, and the needle roller emerges into the bottom of the transfer case without any damage. As the cage all the damage, the bearing model can not find, want to replace the same type of domestic bearings, but the size of large or small are not applicable, and imported bearings have to wait 4 to 6 months. To this end, we take the method of processing needle repair. Repair method is: the processing of the needle and the needle roll with the original phase followed by butter bonding
