中文摘要：

研究中采用平均Reynolds方程进行轴承的动力润滑分析，采用变形矩阵方法计算轴承表面变形。结果表明，偏心率较大时，润滑油黏压效应对倾斜轴颈轴承润滑性能有较大影响，特剐是当倾斜角较大时，影响更为显著。不考虑轴承表面变形情况下，当偏心率较大且轴颈倾斜角也较大时，表面粗糙度对倾斜轴颈轴承润滑性能产生影响；表面形貌方向参数在最小油膜厚度与表面综合粗糙度的比值较小时对倾斜轴颈轴承润滑性能产生显著影响。计入轴承表面变形影响时，轴承表面粗糙度以及表面形貌方向参数对倾斜轴颈轴承润滑性能影响很小。轴颈不倾斜时，轴承表面变形对轴承润滑性能的影响很小；轴颈倾斜时，轴承表面变形的影响比较显著，偏心率越大，轴承表面变形对倾斜轴颈轴承润滑性能的影响越大。

英文摘要：

Average Reynolds equation was used to analyze bearing lubrication. The surface deformation of bearing was calculated by deformation--matrix method. The results show that the oil viscosity--pressure relationship has large effect on the lubrication characteristics of misaligned bearing, especially under condition of great misalignment angle. The surface roughness affects lubrication characteristics of misaligned bearing when eccentricity ratio and angle of journal misalignment are all large and not considering surface deformation of bearing. The directional parameter of surface has obvious effect on lubrication of misaligned bearing when ratio of least film thickness to surface roughness is small. The surface roughness and directional parameter of surface have little effect on lubrication of misaligned bearing when considering deformation of bearing surface. Although having little effect on lubrication of aligned bearing, the deformation of bearing surface has remarkable effect on lubrication of misaligned bearing. The larger the eccentricity ratio,the greater the effect of the deformation of bearing surface on lubrication of misaligned bearing.
