摘 要: In recent years, use of textured surfaces has gained lot of momentum for improving the performance of tribopairs. This article studies the influence of spherical shape micro-textures on the performance of hole-entry hybrid spherical journal bearing. Different arrangements of micro-textures (i.e., fully texture and partially texture) are used to study the performance behavior. The governing modified Reynolds equation for spherical journal bearing and flow equation of capillary restrictor are solved using Finite element method. Additionally, stability parameter of bearing system is numerically computed for different values of bearing span angle. The obtained results reveals that by application of spherical micro-dimple on bearing surface provides enhanced value of stability parameter, whereas frictional loss decreased corresponding to non-textured hybrid spherical journal bearing.

近年来,采用纹理表面以提升摩擦副性能的趋势日益显著。本文研究了球形微纹理对孔入口混合式球轴承性能的影响。通过不同排列方式的微纹理(即全纹理和部分纹理)来分析其性能表现。利用有限元方法求解了球轴承的修正雷诺方程以及毛细管限制器的流动方程。此外,还针对不同的轴承跨度角度数值计算了轴承系统的稳定性参数。结果表明,在轴承表面应用球形微凹槽可提高稳定性参数值,而与无纹理混合式球轴承相比,摩擦损失有所降低。
