提出了贫油收敛区流体动压润滑的计算方法，研究了上瓦带挡板的椭圆轴承性能．结果表明该种轴承可明显地提高稳定性，在载荷较小的情况下即可进入恒稳工作区，并且平均温升低；静、动态性能明显好于同尺寸的椭圆轴承
The calculation method of fluid dynamic pressure lubrication in lean oil convergence zone is proposed, and the performance of oval bearing on upper tile baffle is studied. The results show that this type of bearing can significantly improve the stability of the load in the case of small into the steady work area, and the average temperature drop; static and dynamic performance is significantly better than the same size oval bearings
