| 摘 要： |
ANSYS FLUENT computational fluid dynamics (CFD) software was used to develop a full-scale model of a singlephase oil flow in a deep groove ball bearing (DGBB). The CFD model was used to investigate fluid flow characteristics as a function of bearing geometry and operating conditions. The underlying theory, boundary conditions and development of the model are described in detail. Major features of the model, including meshing techniques, mesh density and geometric clearances, were determined by performing parametric studies. Streamlines, velocity vectors and pressure contours are used to investigate various DGBB aspects such as cage design and lubricant properties. The CFD model developed provides a novel approach to study DGBB fluid flow and the effect of cage geometry on bearing performance.
使用ANSYS FLUENT计算流体动力学（CFD）软件，开发了深沟球轴承（DGBB）中单相油流的全尺寸模型。通过CFD模型研究了流体流动特性在轴承几何形状和运行条件下的变化。文中详细介绍了模型的理论基础、边界条件以及建模过程。模型的主要特征，包括网格划分技术、网格密度和几何间隙，均通过参数化研究确定。利用流线、速度矢量和压力分布图，对轴承盖设计及润滑剂性能等DGBB相关方面进行了分析。所建立的CFD模型为研究DGBB中的流体流动以及轴承盖几何形状对轴承性能的影响提供了一种新颖的方法。 |
