我单位使用的法国贝利特10米~3矿用汽车发动机曲轴止推凸缘端面磨损严重。经研究大胆采用焊前把止推凸缘全部车掉,从轴颈开始用振动堆焊一次连续堆焊完。堆焊宽度:根部为25毫米,顶部为15毫米,外径堆至135毫米左右,然后车削。施焊参数为:工作转数2.7(转/分),焊丝进给速度1.51(米/分),焊丝材质65Mn,直径1.6毫米。经这样修复,尺寸精度、强度、硬度等都满足了使用要求,无气孔等缺陷。已修复使用的曲轴,至今没有发生问题。
I use the French Belite 10 m ~ 3 mine car engine crankshaft thrust flange face serious wear and tear. The study boldly used to push all the flange before the car off, starting from the journal with a continuous surfacing surfacing surfacing. Surfacing width: 25 mm at the root, 15 mm at the top and 135 mm at the outer diameter before turning. The welding parameters are: Working speed 2.7 (rev / min), wire feed speed 1.51 (m / min), wire material 65Mn, diameter 1.6 mm. After this repair, dimensional accuracy, strength, hardness, etc. to meet the requirements of use, no holes and other defects. The crankshaft has been repaired, so far no problem has occurred.
