Abstract In recent years, use of textured surfaces has gained lot of momentum for improving the performance of tribo-pairs. 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.

表面纹理对进孔混合球面轴颈轴承性能影响的研究

摘要 近年来，纹理表面的使用在提高摩擦对的性能方面获得了很大的动力。本文研究了球形微织构对进孔混合球面轴颈轴承性能的影响。微纹理的不同排列（即，完全纹理和部分纹理）用于研究性能行为。采用有限元法求解了球面轴颈轴承的控制修正雷诺方程和毛细管节流器的流动方程。此外，对于不同的轴承跨距角值，数值计算了轴承系统的稳定性参数。获得的结果表明，通过在轴承表面应用球形微凹坑提供了稳定性参数的增强值，
