| 摘 要： | 研究了推力球轴承的钢球与滚道间形成的椭圆接触等温弹流润滑问题。据此问题建立的数学模型既有沿接触椭圆短轴方向的卷吸速度分量，又有沿其长轴方向的卷吸速度分量，且速度值处处各异。运用多重网格法求得了几组参数下的完全数值解，并分析了转动速度、中心距、椭圆比等参数对结果的影响。

| Abstract: | The isothermal EHL problem in the contacts between the steel ball and the race of the thrust ball bearing is analyzed The established mathematical model includes the components of the entrainment velocity along both the x and y axes, and the values of these components are varies with the locations Complete numerical solutions are obtained for various parameters with a multigrid solver The influences of the rotating velocity, center distance and the elliptical ratio on the bearing performance are investigated and discussed |
