我厂在1980年10月大修的116台汽车中,消耗曲轴43只,价值98900元。可见,为降低修车成本,必须减少曲轴消耗量。而延长曲轴使用期限是减少曲轴消耗量、降低修车成本的重要措施。曲轴的修理,主要是修理曲轴轴颈尺寸和精度,还必须注意修复轴颈的同心度、平行度、曲轴半径以及各连杆轴颈间的夹角等相互位置精度,同时亦应注意保证曲轴原中心线位置不变。一般都采用轴颈重磨的方法来恢复曲轴轴颈尺寸和精度。但是,为了保持曲轴的强
I plant in October 1980 overhaul of 116 vehicles, the consumption of crankshaft 43, the value of 98,900 yuan. Visible, in order to reduce the cost of repairing a car, must reduce the consumption of crankshaft. The extension of crankshaft life is to reduce the crankshaft consumption, reduce the cost of repairing an important measure. Crankshaft repair, mainly to repair the crankshaft journal size and accuracy, but also must pay attention to repair the journal concentricity, parallelism, crankshaft radius and the connecting rod journal angle between the mutual accuracy, but also should be taken to ensure that the crankshaft The original centerline position unchanged. Generally use the method of neck grinding to restore crankshaft journal size and accuracy. However, in order to maintain the strong crankshaft
