二十四、600马力紫油机曲轴变形的矫正(见图22)大连海洋渔业公司一台进口600马力柴油机,因咬瓦事故,造成曲轴弯曲扭转变形1.1毫米,无法继续运转。这在过去只能报废换新,现在采用火焰矫正方法,为修复柴油机曲轴闯开新路。曲轴材料相当于45钢,长3600毫米,轴颈直径150毫米,经检查变形部位在轴端的轴颈部位,
Twenty-four, 600 horsepower Zi oil machine crankshaft deformation correction (see Figure 22) Dalian Marine Fisheries Company imported a 600-hp diesel engine, due to biting accidents, causing the crankshaft bending deformation of 1.1 mm, can not continue to operate. This can only be replaced in the past, now using the flame correction method, to open up a new road for the repair of diesel engine crankshaft. The crankshaft material is equivalent to 45 steel, 3,600 mm long, with a journal diameter of 150 mm, and the axial position of the shaft at the axial end of the deformed part is examined.
