推力轴承瓦面形面对润滑性能影响的研究

The Influence of Thrust Bearing Pad Face Shape on Lubrication Performance

  • 摘要: 以三峡机组推力轴承为研究对象,运用瓦面二次曲面数学模型和三维热弹流润滑性能分析软件,对平面形面、圆柱形面、马鞍形面、横弯形面、球形形面和反横弯形面等6种瓦面形面的推力轴承的最小油膜厚度,最大油膜压力和最高油膜温度等进行了大量的数值计算。在分析和比较上述6种瓦面形面推力轴承优点和缺点的基础上,指出沿周向凸起的瓦面形面及沿径向下凹的瓦面形面均有利于形成收敛的油膜几何形状,从而显著提高轴承润滑性能。

     

    Abstract: In order to study the thrust bearing system of Three Gorge hydroelectric generating set, the mathematical model of preselecting the pad face shape is constructed. The influence of the pad face shapes on the maximum oil film temperature, maximum oil film pressure, and minimum oil film thickness of the bearings was analyzed, by combining the established mathematical model and the software specifically developed for the analysis of three dimensional thermohydro dynamic lubrication, with six kinds of pad face shape including plane shape, cylinder shape, saddle shape, transverse bend shape,spherical shape, and anti transverse bend shape as the targeted research objects. As the results, the pad shapes characterized by circumferential convex and radial hollow are of advantages to form oil wedge and hence greatly improve the lubrication performance of the bearings.
