Influence of textured surface arrangement onhydrodynamic journal bearing performance

The textured bearing performance enhancement passes essentially by a minimum film thickness and a friction torque improvement through an appropriate surface texture geometry and

The variations in the bearing static characteristics (load capacity, maximum hydrodynamic pressure, friction torque, axial film flow, attitude angle, and the energy dissipated in

Improving performance of textured bearing with spherical dimples suggest that contact characteristics such as minimum film thickness, maximum pressure, and friction torque may

Texturing the contact inlet region (cases 10 to 12) has a modest and negative effect on the bearing performances; + 0.1% for the maximum pressure, -0.2% for the film thickness and no

The variations in the bearing static characteristics (load capacity, maximum hydrodynamic pressure, friction torque, axial film flow, attitude angle, and the energy dissipated in

The textured bearing performance enhancement passes essentially by an improvement of aminimum film thickness, a maximum pressure and a friction torque through an appropriate

The use of textured surfaceswith different shapes of microcavities (textures) and at different locations of the texture zone can be aneffective approach to improve the performance
