1台NK-800型汽车起重机在起吊10t重物时未使用支腿,由此造成后桥壳轴头弯曲,轴头法兰盘弯曲断裂。该机后桥主要由轴头1、后桥壳2、法兰盘3、法兰盘与轴颈连接处4等组成,如附图所示。后桥壳原值很高,损坏后仍具有一定修复价值,遂决定对其进行修复。具体步骤如下所述。1.准备工作(1)检测后桥壳材质先对后桥壳材质进行取样,再对取样进行材料力学性能试验和化学成分分
One Taiwan NK-800 truck crane did not use the outriggers when lifting a 10t heavy load, resulting in bending of the axle head of the rear axle housing and bending of the axle flange. The aircraft rear axle mainly by the shaft 1, rear axle housing 2, flange 3, flange and journal connections 4 and other components, as shown in the figure. The original value of the rear axle housing is high, after the damage still has a certain value of repair, then decided to repair it. Specific steps are as follows. 1. Preparations (1) After testing the material of the rear axle shell After sampling the material of the rear axle shell, and then the material mechanical properties of the sample test and test
