一台小四轮拖拉机烧瓦抱轴后,更换了一根新的曲轴,作业不到4小时就发现主轴承油封处漏油,最初从与离合器壳体接合处滴油,后来从飞轮通风孔向外甩油,每作业8小时耗机油1.5～2千克,不足半个月更换油封11个在后主轴颈靠曲柄与7213轴承处加1.5毫米的垫片后,故障排除了。分析其原因是:①新换的曲轴前后主轴颈总长度比原曲轴的短1毫米,就是把主轴承盖上的调整垫片都取掉,也达不到规定的轴向间隙;②曲轴尺寸不合标准,工作起
After a small four-wheel tractor briquetting axle, the replacement of a new crankshaft, homework less than 4 hours to find the main bearing oil seal leakage, the first clutch from the clutch with the Department of drip, and later from the flywheel vents Oil thrown out, each operation 8 hours consumption of oil 1.5 to 2 kg, less than two weeks to replace the oil seal 11 in the main spindle neck bearing and 7213 bearing plus 1.5 mm gasket, the troubleshooting. Analysis of the reasons are: ① for the replacement of the crankshaft before and after the total length of the main journal than the original crankshaft short 1 mm, is the main bearing cap on the adjustment were removed from the pad, also can not reach the required axial clearance; ② crankshaft size Substandard, work from
