S1 95柴油机常发生轴瓦成批“咬瓦”或拉伤、拉毛事故 ,这种故障一般发生在出厂试验过程中的磨合后期至加载初期 (一般发生在柴油机起动运转后 9～ 6 0 min) ,具体原因分析如下。1　质量因素如果计算和试验结果都表明 ,主轴瓦与连杆轴瓦的压力载荷均远小于许用值 ,所受单位压力 S1 95 Diesel engine often occur in a batch of “bite tile” or strain, pulling the hair, the failure usually occurs during the factory test run-in period to the initial load (usually occurs after the diesel engine starts running 9 ~ 60 min) The specific reasons are as follows. A quality factor If the calculation and test results show that the main bearing and connecting rod bearing pressure loads are much smaller than the allowable value, the unit pressure
