为了评价高强化复合式内燃机曲轴轴承的工作能力,在其设计和调试阶段广泛地应用电子计算机进行轴承的完全流体动力计算。同时,计算了轴承间隙中的轴心运动轨迹,并确定轴颈和轴承之间的最小油膜厚度。根据许多研究工作者的意见,最小油膜厚度值是表明轴承结构参数正确选择的主要因素。然而在许多情况下,在柴油机运用中,特别在提高曲轴的转速时,尽管轴承最小油膜厚度计算值是足够
In order to evaluate the working ability of crankshaft bearings of high-strength compound internal combustion engines, a full computerized calculation of the hydrodynamic bearing of the bearing was performed during its design and commissioning stages. At the same time, the movement of the shaft center in the bearing clearance is calculated and the minimum film thickness between the journal and the bearing is determined. According to many researchers, the minimum oil film thickness value is the main factor to show the correct choice of bearing structural parameters. However, in many cases, even though the calculation of bearing minimum oil film thickness is sufficient in diesel engine application, especially when the crankshaft rotation speed is increased
