6TWL 13T 型40吨索引车,后桥刚性平衡梁悬挂中间大轴(附图), 需换新轴,但车架梁体积大,不能上压床,大轴直径西150毫米,过盈配合,采用100吨千斤顶顶压也无效。为此,我们采用在轴端圆周钻一圈小孔,使大轴外径微量塑性收缩后,再用千斤顶一压就卸下大轴,速度快、成本低,不需搬移就解决了修车问题。 6TWL 13T type 40 ton indexing vehicle, the rear axle rigid balance beam suspends the middle big axle (the picture), need to change the new axle, but the frame beam bulky, can not press the bed, the big axle diameter west 150 millimeters, With 100 tons Jack pressure is invalid. To this end, we use drilling a small hole in the shaft end circumference, so that the outer diameter of the plastic shaft after a small plastic contraction, and then use the jack pressure to remove the big shaft, fast, low cost, without moving to solve the car repair problem.
