在拖拉机发动机中,曲轴主轴承与连杆轴承负荷很大,因而受到很大的磨损。图1为Д—54发动机曲轴轴颈和轴瓦平均磨损(一些发动机曲轴颈最大磨损的平均值)的情况。
In tractor engines, the crankshaft main bearing and connecting rod bearing are heavily loaded and therefore subject to significant wear. Figure 1 shows the average wear on Д-54 engine crankshaft journal and bushings (average of some engine crankshaft maximum wear).
