以某型柴油机主轴承为研究对象,计入主轴承表面粗糙度和弹性变形等因素,建立主轴承润滑状态的分析模型,分析了主轴承径向轴颈型线对润滑状态的影响。结果表明,与不考虑径向轴颈型线的计算结果相比,计入径向轴颈型线时,主轴承的最小油膜厚度增加了25.95%,最大油膜压力减小了17.69%,平均摩擦损失减小了6.14%,主轴颈倾斜现象有所改善。随着轴颈表面粗糙度的增加,主轴承的最小油膜厚度增加,最大油膜压力几乎不变,平均摩擦损失增加。
Taking the main bearing of a diesel engine as the study object, the lubrication state analysis model of the main bearing is established by taking the roughness and elastic deformation of the main bearing surface into account, and the influence of the radial profile of the main bearing on the lubrication state is analyzed. The results show that, compared with the calculated results without considering the radial journal profile, when the influence of the radial journal profile is taken into account, the minimum oil film thickness of the main bearing increases by 25.95%, the maximum oil film pressure decreases by 17.69%, the mean friction power loss decreases by 6.14% and the inclination of the spindle neck is improved. With the increase of journal roughness, the minimum oil film thickness increases, the maximum oil film pressure almost invariably, and the mean friction power loss increases.
