Surface structure effects on hydrodynamic bearing lubrication
2004 (English)In: Improvement of bearing performance under severe operating conditions: 3rd EDF/LMS Poitiers Workshop FUTUROSCOPE, 2004Conference paper (Refereed)
In bearings a hydrodynamic oil film separates stationary and moving surfaces reducing friction and eliminating wear. This separation is achieved due to the pressure generation in the converging wedge formed by the surfaces. Thickness of the oil film between the surfaces is an important parameter that affects bearing load carrying capacity and its margin of safety. There are indications that texturing of the load carrying surfaces can provide an additional pressure generation in the oil film and better oil circulation in the loaded zone. Introduction of micro indentations or grooves on the bearing surface can thus contribute to higher load carrying capacity and lower coefficient of friction. Latest experimental data and theoretical findings as well as those available in the scientific literature will be discussed in this paper.
