东风型内燃机车柴油机曲轴在运用中,由于各种因素的影响导致弯曲和断裂的数量日益增多。据我厂不完全统计,因弯曲需进行磨修的曲轴约占总修车台数的25％,因断裂报废的曲轴到目前为止已有89根。从检修的角度出发,本着尽量设法改善曲轴工作条件,延长其工作寿命的目的,就我们积累的一些统计资料,进行了曲轴弯曲、断裂部位分布情况的分析,并提出曲轴检修组装后的检查和调整的一点粗浅看法,供有关制造、
In the application of the diesel engine crankshaft of the Dongfeng diesel locomotive, the number of bending and fracturing is increasing due to various factors. According to our factory’s incomplete statistics, crankshafts to be worn for bending account for about 25% of the total number of cars repaired, so 89 crankshafts have been scrapped so far. From the maintenance point of view, in order to try to improve the working conditions of crankshafts, to extend its working life purposes, some of our accumulated statistics, crankshaft bending, the distribution of fracture site analysis and proposed crankshaft repair assembly inspection And a little superficial view of adjustment for the manufacture,
